Although your new console will not make any noise until you feed it signals,
it has the capability to produce sounds that, when monitored through a moni-
tor system or headphones, can damage hearing over time.The table below is
taken from the Occupational Safety & Health Administration directive on
occupational noise exposure (1926.52):
Duration per day [h] Sound level [dBA, slow response]
890
692
495
397
2 100
1.5 102
1 105
0.5 110
<0.25 115
Conforming to this directive will minimise the risk of hearing damage caused
by long listening periods. A simple rule to follow is: The longer you listen, the
lower the average volume should be. Please take care when working with your
audio system – if you are manipulating controls which you don’t understand
(which we all do when we are learning), make sure your monitoring level is
turned down. Remember that your ears are the most important tool of your
trade. Look after them, and they will look after you. Most importantly: Don’t
be afraid to experiment to find out how each parameter affects the sound;
this will extend your creativity and help you to get the best results.

A1 Safety Symbol Guide
For your own safety and to avoid invalidation of the warranty, all text marked
with these symbols should be read carefully.
To reduce the risk of electric shock, do not remove covers. No user-serviceable
parts inside. Refer servicing to qualified service personnel (i.e., persons
having appropriate technical training and experience necessary to be aware
of hazards to which they are exposed in performing a repair action, and of
measures to minimize the danger of themselves).
The lightning flash with arrowhead symbol is intended to alert the user to the
presence of un-insulated “dangerous voltage” within the product’s enclosure
that may be of sufficient magnitude to constitute a risk of electric shock to
persons.
The exclamation point within an equilateral triangle is intended to alert the
user to the presence of important operating and maintenance (servicing)
instructions in the literature accompanying the appliance.
Headphones safety warnings contain important information and useful tips
on headphone outputs and monitoring levels.
Assemblies or sub-assemblies of this product can contain opto-electronic
devices. As long as these devices comply with Class I of laser or LED prod-
ucts according to EN 60825-1:1994, they will not be expressly marked on
the product. If a special design should be covered by a higher class of this
standard, the device concerned will be marked directly on the assembly or
sub-assembly in accordance with the above standard.
A2 First Aid

B General Installation Instructions
Please consider besides these general instructions also any product-specific
instructions in the “Installation” chapter of this manual.
B1 Unpacking
Check the equipment for any transport damage. If the unit is mechanically
damaged, if liquids have been spilled or if objects have fallen into the unit,
it must not be connected to the AC power outlet, or it must be immediately
disconnected by unplugging the power cable. Repair must only be performed
by trained personnel in accordance with the applicable regulations.
B2 Installation Site
Install the unit in a place where the following conditions are met:
within the specified limits during operation of the unit. Relevant values
are the ones at the air inlets of the unit (refer to Appendix 1)
precautions must be taken before and after operation (refer to Appendix
1)
unit are a functional part of the design and must not be blocked in any
way during operation (e.g. by objects placed upon them, placement of the
unit on a soft surface, or installation of the unit within a rack or piece of
furniture)
-
light, spotlights)
B3 Earthing and Power Supply
Earthing of units with mains supply (class I equipment) is performed via
battery operation (< 60 V, class III equipment) must be earthed separately.
Earthing the unit is one of the measures for protection against electrical shock
hazard (dangerous body currents). Hazardous voltage may not only be caused
by a defective power supply insulation, but may also be introduced by the
connected audio or control cables.
If the unit is installed with one or several external connections, its earthing
must be provided during operation as well as while the unit is not operated.
If the earthing connection can be interrupted, for example, by unplugging
the mains plug of an external power supply unit, an additional, permanent
earthing connection must be installed using the provided earth terminal.
Avoid ground loops (hum loops) by keeping the loop surface as small as
possible (by consequently guiding the earth conductors in a narrow, parallel
way), and reduce the noise current flowing through the loop by inserting an
additional impedance (common-mode choke).
Installation
V
Installation / EMC
Should the equipment be delivered without a matching mains cable, the
latter has to be prepared by a trained person using the attached female plug
(IEC 320 / C13 or IEC 320 / C19) with respect to the applicable regulations
in your country.
line voltage matches the equipment rating (voltage, frequency) within the
admissible tolerance. The equipment fuses must be rated in accordance with
the specifications on the equipment.
Equipment supplied with a 3-pole appliance inlet (protection conforming to
class I equipment) must be connected to a 3-pole AC power outlet in such a
way that the equipment cabinet is connected to the protective earth.
For information on mains cable strain relief, please refer to Appendix 2.

Equipment of this protection class must be earthed using the provided earth
terminal if one or more external signals are connected to the unit (see expla-
nation at the beginning of this paragraph).
B4 Electromagnetic Compatibility (EMC)
The unit conforms to the protection requirements relevant to electromagnetic
a way that other equipment and systems can be operated normally
that it can operate properly
The unit has been tested and conforms to the EMC standards of the speci-
fied electromagnetic environment, as listed in the following declaration.
The limits of these standards ensure protection of the environment and cor-
responding noise immunity of the equipment with appropriate probability.
However, a professional installation and integration within the system are
imperative prerequisites for operation without EMC problems.
For this purpose, the following measures must be followed:

by keeping the relative humidity above 30%. Further measures (e.g. con-
ducting floor) are usually unnecessary and only effective if used together
with corresponding personal equipment
care that the surrounding building structure allows for sufficient capacitive
coupling of the operator. This coupling can be improved by an additional,
conducting surface in the operator’s area, connected to the equipment
housing (e.g. metal foil underneath the floor covering, carpet with conduc-
tive backing)
C Maintenance
All air vents and openings for operating elements (faders, rotary knobs) must
be checked on a regular basis, and cleaned in case of dust accumulation. For
cleaning, a soft paint-brush or a vacuum cleaner is recommended.
Cleaning the surfaces of the unit is performed with a soft, dry cloth or a soft
brush.
Persistent contamination can be treated with a cloth that is slightly humidified
with a mild cleaning solution, such as dishwashing detergent.
For cleaning display windows, commercially available computer/TV screen
Never use any solvents for cleaning the exterior of the unit! Liquids must
never be sprayed or poured on directly!
For equipment-specific maintenance information please refer to the corre-
sponding chapter in the operating and service manuals.
D Electrostatic Discharge during Maintenance and Repair

Appendix 1: Air Temperature and Humidity
General
Normal operation of the unit or system is warranted under the ambient condi-
tions defined by EN 60721-3-3, set IE32, value 3K3.
This standard consists of an extensive catalogue of parameters, the most
important of which are: ambient temperature +5...+40 °C, relative humidity
5...85% (i.e., no formation of condensation or ice); absolute humidity 1...25 g/
m³; rate of temperature change < 0.5 °C/min. These parameters are dealt with
in the following paragraphs.

ture range (i.e. temperature of the incoming air) of +5 °C to +40 °C. When
rack mounting the units, the intended air flow and herewith adequate cooling
must be provided. The following facts must be considered:

corresponds to 2.12 m³/min.
failure or illumination with spot lamps), the outgoing air temperature must
be measured directly above the modules at several places within the rack.
The trigger temperature of the sensors should be 65 °C to 70 °C
Frost and Dew
The unsealed system parts (connector areas and semiconductor pins) allow
for a minute formation of ice or frost. However, formation of dew visible to
the naked eye will already lead to malfunctions. In practice, reliable opera-
tion can be expected in a temperature range above –15 °C, if the following
general rule is considered for putting the cold system into operation:
If the air within the system is cooled down, the relative humidity rises. If it
reaches 100%, condensation will arise, usually in the boundary layer between
the air and a cooler surface, together with formation of ice or dew at sensi-
tive areas of the system (contacts, IC pins, etc.). Once internal condensation
occurs, trouble-free operation cannot be guaranteed, independent of tempera-
ture.
-
mation of condensation or ice. Only with a minute formation of ice, direct

evaporation (sublimation) may be expected; otherwise the system must be
heated and dried while switched off.
A system without visible internal formation of ice or condensation should be
heated up with its own heat dissipation, as homogeneously (and subsequently
as slow) as possible; the ambient temperature should then always be lower
than the one of the outgoing air.
If it is absolutely necessary to operate the cold system immediately within
warm ambient air, this air must be dehydrated. In such a case, the absolute
humidity must be so low that the relative humidity, related to the coldest
system surface, always remains below 100%.
Ensure that the enclosed air is as dry as possible when powering off (i.e. before
switching off in winter, aerate the room with cold, dry air, and remove humid
objects such as clothes from the room).
These relationships are visible from the following climatogram. For a con-
trolled procedure, thermometer and hygrometer as well as a thermometer
within the system will be required.
+20 °C and a relative humidity
of 40% is switched off in the evening. If the temperature falls below +5 °C,
the relative humidity will rise to 100% (7 g/m³); dew or ice will be forming.

1 SYSTEM DESCRIPTION
1.1 Introduction
The Studer Micro Series is a compact OnAir broadcast and production mixing
system.
It has been designed with focus on very easy operatability - whilst providing
features for professional broadcast production, which are normally only found
in more complex OnAir mixers.
Eventough it has specific OnAir features, it can also be used as a versatile
production mixer for many other applications.
The Studer Micro Series can currently be used as a standalone unit, and later
it will have the functionality to be part of a networked studio environment.
The minimal system consists of a base unit only which is called Micro Core.
The Micro Core is then operated via a browser GUI, which can be run on a
tablet, notebook or desktop computer. (iOS, Android, Windows, MacOS, and
Linux platforms are supported).
For local operation, a computer screen and mouse and keyboard can be
directly connected to the Micro Core to operate the GUI.
For users who wish dedicated hardware controls, the Micro Core can be
combined with one or two desk modules - adding faders, buttons and channel
displays for real hands-on control. The desk module is called Micro Fader.
This manual is written for users that operate the mixer - and also for setup
and installation of the mixer (last part in the manual).

The heart of the Micro Series is the fanless, rackmountable 3 RU Micro Core.
It is the actual mixing engine, also providing USB connectivity and status
LEDs on the front side, and audio I/O as well as a multitude of other connec-
tors on the rear side.
By using the included rackmount-kit, the Micro Core can also be mounted in
“reversed” way , making it easier to access all audio I/Os from the front of
the rack.

1.2.2 Micro Fader
Up to two Micro Fader modules can be connected to one Micro Core - giving
access to up to 12 faders. This allows professional Radio OnAir operation.
Connection is via a single cat5 cable for communication protocol and power.
1.2.2.1 Operating Elements
There are six non-motorized faders. Each channel strip has its own display
Per channel strip, two small option buttons are placed directly below the
display. Further down, two large buttons are placed above the fader. These
buttons are used for Rec an Cue functions. Then below the fader there are
another two large buttons : the On- and the PFL /Off button.
Also a signal indication- as well as an overload LED are placed between the
fader and the upper two large buttons.
Display The Micro Fader module provides a two row LCD display to indicate :
( The background of the function name is inverted when the function is active.)
(default) to blue. The backlight is flashing if a channel that is On-Master is
pending on snapshot parameter recall.
Buttons The Micro Fader module features six buttons per channel strip. From top to
bottom of the strip, they have the following functions :
on the lower row of the display. (Text 1 and Text 2)
REC button is the same as the REC button in the GUI. This button
contains one yellow LED . The OffAir Record function is indicated yellow.
CUE/Blank button. This button contains two LEDs, red and yellow.
(The CUE function is indicated yellow).
ON button is the same as the ON button in the GUI. This button contains
two LEDs, red and yellow.The Channel ON status is indicated red.
PFL/OFF button.This button contains two LEDs, red and yellow. The
PFL function is indicated yellow, the OFF function not illuminated.

Except for the REC button and the ON button, the buttons can represent
different functions.
Faders Each Micro Fader module features six none motorized faders at 36mm pitch.
Because the faders are not motorized, there is the need for an Auto Takeover
mechanism that is an aid to manually synchronise fader positions between
GUI and physical faders. Auto Takeover indication is on the channel strip
display, on the upper row (Text0).
Auto Takeover Auto Takeover works like this :
When the position of the physical fader differs from the fader value in the
GUI, the channel’s display indicates this by showing either FADER UP or
FADER DOWN. This is a request to the operator, to touch the fader and move
it to the identical position that the fader value has in the GUI. This can be
done very easily, without looking at the GUI.
As soon as the fader is touched, the display shows a value. This value is fol-
lowed by the word UP or DOWN. This means that the fader must be moved
the value in dB’s up or down to match the current fader value of the GUI.
The larger the value, the longer the way that the fader needs to be moved
until the current fader value is met. Since the value is being udated while
the fader is moved, it is easy to fade to the area where the value becomes 0.
Once the fader is there, the display indicates that Auto Takeover is complete
for this channel, by showing the word TAKEOVER, which will be flashing
for a couple of seconds.
This procedure must be carried out for every channel that is assigned to a
phisycal fader of a Micro Fader module, where the channel strip’s display
shows FADER UP or FADER DOWN.
LEDs OVL : A red LED indicating analogue clipping.
SIG:A green LED indicating the signal after the INPUT processing block.
1.2.2.2 Connectors
The Micro Fader module features two connectors on the rear side.
One RJ45-connector where the connection to the Micro Core is made.
And one USB connector that can be used to power an optional iPad.
1.2.2.3 iPad mount
An iPad can be mounted on the top rim of the Micro Fader module. This is
optional.
The iPad displays the normal Micro Series GUI.

1.3 Main Features
The Studer Micro Series mixer is fully loaded with mixer functionality :
Automatic Gain Control
1.4 How can it be operated
The Micro Core has an integrated webserver, which allows any computer that
is able to run HTML5 pages on its webbrowser to control the Micro Core.
There is no need to install any drivers or applications. The only requirement
is a network connection to the Micro Core - this can either be via wireless
LAN or via a wired LAN connection to the Micro Core’s Ethernet port.
Once the webbrowser has been directed to the Micro Core’s IP address, the
control screen is loaded and control elements which are optimized for touch-
screens with multitouch-operation allow to control the mixer.
Note : For browser control of the Micro Core, cookies must be enabled.
1.4.1 GUI
The entire functionality of the Micro Series can be controlled from the GUI
(Graphical User Interface) running on a webbrowser, as described above, or
through local connected screen, keyboard and mouse.
Note : GUI on iPad Please don’t use Mozilla Firefox or Chrome browsers on the iPad, as they
both don’t support full screen mode.
Use the Safari browser instead, and create a Home Screen Icon, which opens
the browser in full screen mode.
1.4.2 Micro Fader
In addition to the GUI, one or two hardware Micro Fader modules can be
connected to the Micro Core. This provides hardware faders and buttons for
those operators who wish full tactile control of the Micro Series mixer.

1.5 Hookup possibilities via Network
Ethernet A very secure way to control the Micro Core is to use a wired LAN connec-
tion. An ethernet cable between your control PC/Laptop and the Micro Core’s
network port 1 is all that is needed. This connection can also be made via a
corporate network, or even via Internet.

Of course the Micro Core can also be controlled by a wireless device when
connecting an external WLAN router to the Micro Core’s network port.

WLAN The Micro Core has an internal Wi-Fi port, allowing to join any existing
WLAN. Once the control device (PC/Laptop/Tablet) also has access to the
same WLAN, it is able to control the Micro Core.

Internal Hotspot The Micro Core is able to produce its own WLAN, or with other words, it
has its own WirelessAccessPoint (WAP). A control device can then simply
join this WLAN and will be able to control the Micro Core without the need
of any external network components.

1.6 Hookup possibilites direct GUI Control
The simplest way of controlling the Micro Core is using the peripherial
interface where a screen and mouse and keyboard can be connected, without
any network in between.

2 GUI OPERATION
The GUI operation concept of the Micro Series is organized in three levels :
L1 - Operations level
L2 - Options level
L3 - Configuration level
L1 The Operation level is the top page of the GUI. Here, all controls which are
needed for a DJ to run a live radio show are easily accessible.
L2 The Options level only shows the options of one specific channel. It is opened
by double-clicking (or touching) the channel’s label.
L3 The Configuration level is entered by using the Config button. Then the
Config view is shown, which consists of several pages.
In the following chapters, all three levels are described.
2.1 L1 - The operation level (for DJs)
2.1.1 Main Page
For basic DJ operation, all necessary control elements can be found on the
Main page of the GUI. The Main page consists of three sections :
Left section
Central section
Right section (Watch and Metering/Monitoring)

Le t section Central section ight section
Left Section The left section of the GUIs operation view displays the control elements that
are selected by the view buttons in the central section. This section is the main
working surface for the DJ.
Central Section The section in the middle of the GUI provides the view buttons, elements for
navigation, the OnAir indication, as well as the button to access the mixer
settings.
Right Section The right section of the GUIs operation view displays control elements for
Watch, Recording, Snapshot handling, Metering and Monitoring

2.1.2 Mixer Channels
Before the channel view is explained, it is essential to understand the concept
of having different channel roles.
2.1.2.1 Channel Roles
All twelve DSP channels are identical. But every channel can be given a
specific “role”. The role links specific functionality and operating elements
to a channel, in order to make it capable of a specific task.
The following channel roles can more or less freely be used :
Channel Role Description Additional Buttons Specific Input
Default for a simple input channel, no special behaviour
DJ for a mic source located in the control room (CR) Mute
Guest for a mic source located in the control room (CR) Talk
Input for sends 1 the bus owner of a N-1 bus Talk
Input for sends 2 the bus owner of a N-1 bus Talk
Input for sends 3 the bus owner of a N-1 bus Talk
Input for sends 4 the bus owner of a N-1 bus Talk
Track for the input channel that is linked to the Track Player Next, Display Is linked to USB
In 3/4
Jingle for the input channel that is linked to the Jingle Player Jingle buttons Is linked to USB
In 1/2
Already in the factory-reset state of the mixer, the channels have different
roles.
Channel
Num er Channel ole a ter Factory- eset Channel La el Channel Source
1 DJ DJ MIC HQ MIC/LINE #1
2 Guest GUEST 1 HQ MIC/LINE #2
3 Guest GUEST 2 HQ MIC/LINE #3
4 Guest GUEST 3 HQ MIC/LINE #4
5 Input for sends 1 PHONE 1 ANALOG LINE #9
6 Input for sends 2 PHONE 2 ANALOG LINE #10
7 Jingle JINGLE USB 1/2
8 Track PLAYER USB 3/4

10 Default LINE 1/2 ANALOG LINE 5/6
11 Default LINE 3/4 ANALOG LINE 7/8
12 Default NET AES67/DANTE 1/2
Channel roles are configured in the Config View of a channel, under the
Source tab.
Depending on the channel role, the channel view can vary, because of addi-
tional buttons that need to be operatable.

2.1.3 Chan View
The channel view shows the faderstrips of the mixers input channels. All
twelve input channels are shown - by using the scroll buttons in the central
section the operator can navigate to the desired faderstrips. Also swiping can
be used on a touchscreen to navigate between the faderstrips.
The operating elements that are common to all channels are these (channel role “Default”) :
1

[1] Label The channel label display shows the channels name. This name can be entered
in the Options page of the channel. The labels background changes from grey
to blue, when the channel is ‚On-Master‘.
[2] Rec button The Rec button assigns a channel to the record bus.
[3] OVL Indicator The overload indicator is used to indicate analogue input clipping (A/D con-
verter), which means overload is never illuminated for digital sources. For
Micro Series

SW V1.2
channels with analogue inputs, OVL is illuminated as soon as the input level,
before input calibration, reaches 0dBFS.
[3] SIG Indicator The green signal indicator is illuminated as soon as the signal is > -40dB. The
signal is captured after the INPUT processing block and therefore it is also
influenced by the analogue gain as well as the digital input calibration of the
channel.
[4] Fader The channel fader. It can be operated by mouse or touch. The mousewheel can
also be used to operate the fader when hovering the mousepointer anywhere
over the fader area.
[5] On button The On button activates the channel. When the fader is open, the On button
toggles the channel ‚on-air‘ and ‚off-air‘.
[6] PFL button The PFL button allows the operator to pre- listen to this channel even if the
fader is closed or the channel is not switched to ‚On‘. PFL stands for PreF-
adeListening. The Reset PFL button in the central section releases all channels
from PFL.
The channel of other roles than “Default” have additional buttons :

[1] Mute button The Mute button is intended for the use as a cough-button. It is only available
for channels of the role DJ.
[2] Talk button The Talk button allows the DJ to talk either to a Guest via the Guest’s head-
phone monitor - or to a N-1 output of a channel of the role “Input for sends”.
[3] Next button The Next button allows to change to the next audio file of the current playing
playlist. For details please see chapter 2.1.6.1 Track Player Operation.
[4] Status Display The Status Display of the Track Player Channel shows the name of the current
title, as well as a progress bar and the current playing time.
[5] Jingle buttons The Jingle buttons are used to play specific Jingles from the Jingle channel.
More Jingle buttons can be found in the Play view.

The files are played back via the channel with the role “track”.
The Track Player is controlled on Operation Level L1 of the Track Player
Channel through the following elements :
FaderStart To start the Track Player via FaderStart, the channel ON button must be active,
and the fader must be opened. Then, playback of the the currently selected
audio file or the next file in the playlist starts from begin.
Closing the Track Player Channel will stop playback and re-positions to the
file begin. In case of a playlist, the next file of the playlist will be positioned
to its begin.
This allows playing all files of the selected playlist just by opening and clos-
ing the fader, or by turning the channel ON and OFF.
Next button The Next button operation works similar as activating FaderStart , with the
the following difference - it can also be activated while a file is already play-
ing and it doesn’t stop playback. Therefore, the Next button function allows
playback of the next file of the playlist without the need of manually stopping
the currently playing file first.
Note, that the fader must be open when using the Next button in order to make
sure playback reaches program-, record and send buses.
The Next button function is defined as follows:
During Stop:
When the Next button is activated while no playback is in progress, the Track
Player Channel is turned to ON and playback of the currently selected audio
file or the next file of the selected playlist starts from begin.
During Playback:
When the Next button is activated while playback is in progress, the current
playback stops and playback of the next file of the selected playlist starts from
begin.
In case of a selected file instead of a playlist, the currently selected file restarts
playback from its begin.
PFL button When no track is playing, activating the Track Player Channels PFL button,
the playback of the currently selected audio file is started and the Track Player
Channel remains OFF. When a file is already playing, the Track Playe Chan-
nels PFL can be activated, but then playback of the file is not interrupted nor
will playback of this file be re-started.
Since there is only one instance of the Track Player, PFL of a track, while a
different track is currently playing is not possible!
When no file is playing, any desired audio file can be prelistened in the Play
View. This is done with the PFL button that is located at the and of each track
next to the play button.
Playing order Usually the audio files of a playlist are played in the order they are defined
by the list. Once a file is playing, there is a blue frame around the Title Bar

of the file that will be played as next file.
‘next file to be played’ This file is marked as ‘next file to be played’.
Without any interference of the operator, this file will be played when the
current playing file has come to its end. If the operator decides, that a different
file should be played as next file, she/he can long-click/touch on any other
file in the playlist, whereupon the long-clicked file will be marked with the
blue frame and becomes the next file to be played.
The next file to be played from the playlist is defined as follows :
the playlist is automatically selected as the next file to be played. After
the last file from the playlist starts playback, the first file in the playlist is
automatically selected as the next file to be played.
2.1.6.2 Jingle Player Operation
The Jingle Player supplies stereo audio playback through the inputs USB 1/2.
Any channel that is configured to have these inputs as source is in the role
“Jingle Player” and is used to control the playback of the jingles.
Nine different jingle can be loaded which will then be available for playback
through nine direct access buttons.
Audio files can be assigned to jingle buttons through the following file name
conventions:
Jingle Player files must be located in the ‘Jingle’ folder of the USB storage
media.
The filename begins with the character “J” followed by a one- or two digits
button number 1..9 or 01...09.
The first eight characters of the filename are indicated on the jingle button.
If the filename is more than eight characters long, the surplus characters are
omitted.
The following audio file formats can be used for the Jingle Player :
Format File E tension Description
Wave .wav uncompressed audio
AAC .aac lossy audio compression
MP3 .mp3 lossy audio compression
Ogg Vorbis .ogg lossy audio compression
AIFF .aif uncompressed audio
FLAC .flac lossless audio compression
Example : J01_Logo 1.wav is the file that will be played when button 1 is pressed. The
button will be labeled “Logo 1”.
J2Applaus.wav is the file that will be played when button 2 is pressed. This
button will get the label “Applaus”.
The Jingle Player is controlled on Operation Level L1 of the Jingle Player
Channel through the following elements :

If PFL is active, the Jingle Player channel is set to OFF.
Stopping a jingle A currently playing jingle can be stopped by either turning the Jingle Player
Channel to OFF or pressing the STOP button in the Play View page.
Playback of a Jingle stops automatically at its end without any user action.
When playback is stopped, the Jingle Player Channel is automatically
switched to channel OFF.
Note 1 : If the Jingle Player Channel is set to ON, eventhough no Jingle is playing,
the Jingle Player Channel is On Air.
As in the GUI, there is no fader to this channel, the On Air state is simply
activated by the channel ON/OFF button.
Note 2 : There is a difference to Micro Series mixers with connected Micro Fader
modules. In the case of connected Micro Fader module, the Jingle Player
Channel can have a fader - which then also has an effect on the On Air state
of the Jingle Player Channel.

[1] 48V Switches phantom power (48V) to the microphone on and off.
[2] Highpass filter Activates a highpass filter on the analog side of the microphone input, before
theA/D converter. This can be useful to filter out rumbling noise on speach
signals. The cutoff frequency of this filter is fixed at 75Hz and it has a slope
of 12dB/oct.
[3] Mic gain This fader sets the microphone gain.The gain range is 86dB and the absolute
numbers on the fader-scale are depending on the Max Level of the analog
I/O. Max Level is defined in the Settings page.
On channels with Line inputs as source, other control elements are displayed
in place of the Mic control elements.
Max Level The Max Level setting defines the systems reference line level for 0dBFS.
This is a global setting found on the Settings-page. But it can also be set on
a channel by channel basis. This setting needs to correspond with the actual
level calibration of the analogue input- and output interfaces. As a standard,
the Micro Core is shipped with all analogue levels calibrated to +9dBu. This
means that the highest possible analog signal that leaves the mixer is +9dBu.
And it also means, that signals which are higher than +9dBu will clip the A/D
converters.

3 SETUP
3.1 Setting up the Network
To configure all network settings, please go to the Settings page. There, on
the Network tab, you can configure the network settings to your work with
your network environment.
Please see in chapter 1.5 how the Micro Core can be used in a network, and
then in chapter 2.4 how the settings are configured.
3.2 Setting up the Micro Fader modules
To configure one or two Micro Fader modules that are to be used with the
Micro Core, please go to the Settings page. There, on the Desk Modules tab,
you see all available Micro Fader modules, and you can assign a range of
channel strips to one or two of them. This comfoguration process is called
“pairing”.
Please see in chapter 2.4 how these settings can be configured.
Micro Fader Web GUI If a browser is prompted to the standard IP address of a Micro Fader module
(10.10.2.2) - the settings page of the connected Micro Fader module is
shown.
In the page, the device settings can be changed and updated :
Important : After changing any of the Micro Fader’s settings, first click on the Update
Settings button, and then on the Reboot Device button. Only after a reboot
Micro Series

of the Micro Fader module, all of the changed settings will be applied.
Note : It is necessarry to change the IP address of one Micro Fader module, if two
Micro Fader modules are to be used together. (This needs to be done before
the Micro Fader modules can be assigned to the Micro Core.)
Fader Calibration The fader’s 0dB position can be calibrated.
And the fader start point can also be calibrated - which is the position where
the fader start signal is triggered when opening the fader from -infinity
towards 0 dB.
3.3 Setting up the Monitoring
In total, there are two monitoring sections that can be used within the Micro
Core.
The actual physical outputs that are used by these two monitoring sections
can be freely assigned.
Step 1 Chose the monitoring section that you would like to configure.
Step 2 What should be connected ?
- Active loudspeaker
- Headphone
- Meter
Step 3 What physical connector ?
Step 4 Assign the output :
This is done on the CR Config page, on the Targets tab.
Any of the outputs viewable on this page can be used :
Micro Series
Micro Series 1-85
Document generated: 04.10.17 SW V1.2
The selectable sources for the monitoring sections are the following :
CR MON LSP (L)
CR MON LSP (R)
CR MON LSP (M)
These are the outputs of the CR monitoring section that are meant for a direct
connection of an active loudspeaker. Normally, the left and right speakers
are wired individually. The two stereo signals are downmixed internally to a
mono output (on the source marked M). This source can be used if a single
mono speaker will be used as CR mon speaker.
CR MON DIRECT (L)
CR MON DIRECT (R)
CR MON DIRECT (M)
The sources above, named DIRECT, are providing the same signal as CR
MON LSP, but without level control. These are normally used to connect a
meter that measures the level of the currently selected CR source. Be careful
not to connect an active loudspeaker to such a DIRECT source, as the signal
is fullscale and no level control is possible.
DJ HP (L)
DJ HP (R)
DJ HP (M)
These are the outputs carrying the HP signal of the Control Room Monitoring.
DJ HP DIRECT (L)
DJ HP DIRECT (R)
DJ HP DIRECT (M)
The HP signal of the Control Room Monitoring is also available as DIRECT
signal that has no volume control. This could be used if fed to a remote HP
amplifier when the DJ is remotely operating the Micro Core.
GUEST HP (L)
GUEST HP (R)
GUEST HP (M)
The GUEST HP Monitoring section only has a volume controlled output.
When the outputs are assigned as desired, the Config pages of the monitoring
sections can be used for further configuration.
CR Monitoring Options page :

PFL to Mon With this option active, the current CR monitoring source gets replaced with
the PFL signal, as long as any PFL is active.
Mono This button mixes the stereo CR source down to a mono signal for both, CR
speakers and CR headphones.
HP Split With this mode active, the PFL signal will be fed to the left channel of the
headphone, if PFL is active on any channel. On the right channel, still the pre-
viously selected CR source will be heard. Both signals are then downmixed
to mono.
Once PFL is released, the current CR source will be heard in stereo again.
If PFL is already selected as the CR source, actually pressing PFL on any
channel will not change the stereo PFL bus as the monitoring source.
Guest Monitoring Options page :
Monitoring Source Here the actual monitoring source is chosen. FOLLOW CR choses the cur-
rently active source of the CR monitoring section.
Note : TB return signals are heard via the two monitoring sections :
Please note that TB return signals are fed to the CR monitoring section in
case of TB to the DJ.
In case of TB to Guest, TB return signals are fed to the guest monitoring sec-
tion.
When a TB return is active, the current monitoring signal will be dimmed by
20dB.
3.4 Setting up TB
The Micro Core provides a powerful internal TB matrix.
Micro Series
Micro Series 1-87
Document generated: 04.10.17 SW V1.2
The DJs TB possibilities The DJ can use the Talk buttons on channels of the role “Guest” and “Inputs
for Send” and talk to the Studio guests and outside sources such as a telefone
guest.
These Talk buttons automatically appear on the GUI. They are meant to be
used by the DJ and therefore use the DJ Mic Input as the source signal.
The DJ can also talk to the External TB target (TB to Extern). The physical
output, where this signal leaves the Micro Core can be assigned freely. Any
of the outputs viewable on the Targets page can be used.
TB TO EXTERN is the name of the signal that has to be assigned.
The TB possibilities of others TB from other channels than th DJ’s input channel can only be activated by
GPI’s.
Via GPI, TBfromCH 1-12 as well as TBfromExtern can be activated to speak
to the following possible targets :
TBtoCR
TBtoDJ
TBtoGuest
TBtoSend1
TBtoSend2
TBtoSend3
TBtoSend4
TBtoExtern
3.5 Setting up N-1 / Sends
There are four send busses within the Micro Core. Each bus can either be
used as an Aux bus or as a N-1 bus.
The setup of all parameters concerning the typ of the bus, as well as the actual
mix from the input channels, can be done in the Config page of the bus. Please
see chapter 2.3.2.
3.6 Setting up GPIOs
GPIO (GeneralPurposeInputs and Outputs) are an effective interface for the
mixer to communicate with the studio environment. The upper d-type con-
nector hosts 12 pairs of pins where a voltage pulse or level can be detected
(GPI). The lower d-type connector hosts 12 pairs of pins where a relay can
establish a connection between the pins (GPO).
GPI’s There are many mixer internal functions that can be used via the 12 GPI’s.
Mixer internal functions that can be triggerd via GPInputs are called Input
Functions.
Please refer to the table in chapter 2.4 for a complete description of all Input
Functions.

3.7 Setting up Dante
To control and setup the Dante network, please use the Dante Controller
software that can be downloaded under :
https://www.audinate.com/products/software/dante-controller
Within the Dante Controller software, all network devices are displayed in a
matrix and you can make the signal routing from and to the different devices.
Within the Micro Core, the received Dante streams are available from the
input ports AES67/DANTE #1 - 8.
The signals that are assigned to the output ports AES67//DANTE#1-8 will
be transmitted as Dante streams.
There are two AES67/Dante ports, which means that the Dante Controller
will see two Micro Core devices when both ports are connected to the Dante
network.
Note : Since the built-in Dante ports do not accept external sync reference (Enable
Sync to External), it is not meaningful to use the Micro Core as Preferred
Master within a Dante/AES67 network.
3.8 Firmware update
To perform a software update of the Micro Core, the latest software file can
be downloaded from the Studer website. The software file has a .zip file
extension and is named like this :
oamupdate-X.X.XXXX-usb.zip
Where the Xs stand for the latest software version.
This file can be copied to the root folder of a USB media, which then can be
inserted into the Play/Rec USB port of the base unit.
Once the USB media is scanned. the software file is automatically detected
and the update process is started. All following process steps are then guided
by instructions that are shown on the screen or GUI of the Micro Core.

3.9 Emergency factory reset
Full factory reset The following scenario executes a full reset including reloading the factory
firmware and factory default settings :
Step 1 Connect a USB keyboard to the Micro Core’s GUI connectors.
Step 2 During startup, as soon as the CORE LED lights up, press the F12 key.
(Press the key in the same way as on a personal computer to enter it’s BIOS
settings.)
As soon as the Micro Core detects the F12 key pressed during startup, it
reloads the factory firmware and resets all parameters to factory default.
Reset of network settings The following scenario resets the network settings to factory default :
Step 1 Connect a USB keyboard to the Micro Core’s GUI connectors.
Step 2 During startup, as soon as the CORE LED lights up, press the DEL key.
(Press the key in the same way as on a personal computer to enter it’s BIOS
settings.)
As soon as the Micro Core detects the DEL key pressed during startup, it
resets the network settings to factory defaults and confirms it by flashing the
blue WiFi LED for 5s.

on a single XLR cable.
Aux Auxiliary mix - an additional mix possibility (four on the Micro Core) that
can be independent of the main PRG master (PRE-Fader Aux) - or that is also
taking the channel fader level into account (POST-Fader Aux).
CUE The CUE button lets the operator listen to the post-fader signals of individual
channels .(As oposed to PFL which is pre-fader-listening.)
CR Control Room monitoring. This is usually the main loudspeaker monitoring
system that is used by the operator or DJ.
Dante Digital audio network through Ethernet cable.
DJ Disc-Jockey - an On Air operator that runs a radio show as a single person.
DSP Digital Signal Processing - the electronic hardware that calculates the audio
processing.
GEQ Graphic Equalizer - an equalizer with 31 filter bands where each band repre-
sents a fixed frequency. The gain sliders of each band are graphically arranged
next to each other - so that the resulting curve of the sliders represents the
GEQ’s filter response.
GPIO General Purpose Inputs and Outputs that can be configured by the operator.
GPI General Purpose Inputs.
GPO General Purpose Outputs.
GUI Graphical User Interface - the actual graphics on the tablet or computer screen
that provides all the control elements of the On Air Micro.
HDMI Interface where a digital screen can be connected (High Definition Multimedia
Interface)
HPF High Pass Filter.
Jingle A jingle is a short song or tune used in advertising and radio production.
N-1 This mode is made for Aux busses that are feeding a return signal to remote
positions. It doesn’t allow the input signal of the remote source to be assigned
to the bus. With this bus mode, the remote source (e.g. a reporter) will never
have his own signal in his return feed. This is optimal to prevent echo’s that
could be introduced through long distance signal transmission.
