3 BP24 UWB Body Pack Transmitter
3.1 Transmitter Controls
An On/Off power switch is located in the battery compartment.
The adjustable transmitter parameters are:
1. System ID (SYS) – Each transmitter must be assigned a system ID (1-9) that
must match the system ID set on the MCU3224
The transmitter will only transmit when it receives a sync pulse and
matching system ID from an active system. This will prevent users with
transmitters assigned the same channel slot on a different system from
interfering if they enter the coverage area.
Note: RP timing signals from separate systems must be RF isolated from
one another to prevent system timing contention in transmitters.
2. Channel Number (CHAN) – The channel slot assigned to the transmitter (01-
24.) Each transmitter in the system is assigned a unique channel number.
3. Input level (GAIN) – Adjustment of the audio input level (0 dB to 20dB in
2dB Steps).
The adjustable transmitter parameters are shown on a display located on the face
of the transmitter.
The display will only be illuminated when the user is adjusting the transmitter.
Pressing any button will activate the display for 10 seconds. After 10 seconds,
display functions will no longer be illuminated although the BP is functioning.
Pressing any button will light the display in order to check for power or operating
condition.
Studio Broadcast System
Page 9 of 26
Adjustment Process:
1. Press and Hold (2 sec) the button associated with the parameter to be adjusted - SYS,
CHAN or GAIN.
2. The selected parameter value will flash on the screen.
3. Make the adjustment via the up down arrow keys.
4. The new value will be shown
5. Confirm the change by pressing the same parameter button as step 1.
6. The changed value will flash twice indicating the parameter change.
Note: If there is no button pressed for a 10 second period the transmitter will
revert to its original settings and the display will go dark.
Note: No parameter changes will be made unless confirmed as indicated in
step 5 above. Pressing a different parameter selection button, or
allowing a 10 second period without any input abandons any change in
process.
Note: GAIN value is automatically sent to and adjusted at the MCU3224
display. BP GAIN setting may also be changed via MCU3224 transmitter

3.2 Batteries
The BP24 operates via 2 x AA size batteries.
When inserting the batteries into the BP24, observe correct polarity as marked.
Do not peel off or damage the outer tube of the battery.
Do not use a leaking battery. If battery leakage occurs, avoid contact with skin. If contact
occurs, immediately was thoroughly with soap and water. If battery leakage comes into
contact with your eyes, immediately flush with water and seek medical attention.
Do not expose batteries to fire. Do not heat, deform, solder, disassemble or modify
batteries.
For best operation, do not use batteries of different types together, old or new batteries
together, or batteries with different charge levels.
3.3 Transmitter Audio Output Routing
The system includes a talkback function utilizing 48 output channels in either the MADI
stream or DANTE/AVB network output. In normal operation, audio will be routed to the
audio channel that matches the channel slot number assigned (Audio Channel = CHAN =
1 - 24). The talkback function is activated by connecting the appropriate transmitter
connector contact (TBD) to ground when the in-line talkback switch is depressed. The
talkback function is a press and hold operation. While the talkback button is depressed,
the audio output will be routed to a channel in the range of 25 to 48 - equal to the
channel slot number + 24 (Audio Channel = CHAN +24). Upon button release, the audio
channel returns to the normal operation on the assigned channel 1-24.

4 RP32 UWB Receiver Module
A two digit display (7 Segment LED) is provided to automatically indicate the receiver
channel number when the RP32 is connected via a CAT5 cable to the corresponding
output channel of the MCU3224. This display serves as the unit’s power indicator. A
visible channel number also indicates that there is a full round-trip connection between
the RP and the MCU communications, confirming that the cable, the RP and the
corresponding MCU3224 channel are all operating appropriately. Should the user prefer
that the LED lights not be illuminated, there is a control option available on the MCU
“tools” screen which allows this RP display lights to be turned off.

RJ45 Connector for Cat5 Cable
Connection to the RP32 is via an RJ45 jack on the rear. Once connected via RJ45 and
shielded CAT5 cable to an MCU, the RP is operational. There is no power switch, and no
further controls necessary. The MCU3224 supplies operating power and control over RP
functions/preferences is available via the tools screen of the MCU3224.
A choice of 2 mounting threads are available on the rear of the RP32. The inserts mate
with either 5/8”-27 thread or ¼”-20 thread adapters.

5 MCU3224 Main Control Unit
The main control unit is the central connection and control point for the system. It also
supplies the power required to operate up to 32 receivers via standard shielded CAT 5
cable. This unit provides operational coordination, regulates system timing and feeds
the output product to the end user’s system as desired. The MCU allows user
control/adjustment of operating preferences and management of both transmitters and
receivers.
The audio outputs - MADI, Networked Audio Protocal are all contained within this 3U
sized unit, with appropriate output connections on the rear. A touchscreen GUI, and
internal headphone monitor output/meter are provided for user control and monitoring.
The MCU3224 operates via 2 fully redundant 110-220V 50-60Hz AC power supplies via 2
separate standard IEC power cables. The unit is fully operational with a single power
cable and power supply. A front panel display will indicate a blue light for the 1st power
supply and a red light for the 2nd power supply.

The user will be able to control the transmitter audio input level from this screen.
The user may press either the up or down arrow to select the desired
gain setting.
This action will cause the new value to be displayed (in red) and a “Set”
button will appear. The setting is not changed on the transmitter
until the set button is pressed.
Activating another function on the GUI or allowing a 10 second
interval without interaction will abandon the change.
Once the set button is pressed, the system will send a command to
the transmitter to change the setting. When the transmitter
acknowledges the change, the set button will disappear, and the setting color will
change back to white.
Note: When the transmitter is not in link this option will not be available.
If the transmitter does not acknowledge the change after several attempts, an error
message will be displayed and the setting will revert to the previous setting. This would
only happen if the transmitter moved out of the coverage pattern during the change
process.
6.3 Matrix Screen - Receiver Measurement
The matrix screen allows the user to visualize specific connections between 32 possible
receivers and 24 possible transmitters. There are two modes: Receiver Test and
Transmitter Test.
In the receiver test mode the user selects a source transmitter - blue buttons on the
right side of the screen - and the screen on the left indicates the active receivers
currently linked to that transmitter. Active receivers are indicated with a blue square;
green fill indicates a link to the selected transmitter.
Studio Broadcast System
Page 19 of 26
The Σ button is used to view receivers that are connected to ANY active transmitter
rather than just a single transmitter. This mode is used to test which receivers are most
effective in a given set up, and may assist in receiver placement.
When the user selects the matrix screen, the system will first check for added receivers;
without interrupting the operation of the active receivers or the audio output. This
gives the user a way to add receivers while the system is in active operation. If the user
plugs in a receiver it will not be active until the system goes through this process.
Pressing the mode swap button switches to Transmitter measurement mode.

6.4 Matrix Screen – Transmitter Measurement
In the transmitter measurement mode the user selects one of the active receivers – blue
buttons on the right side of the screen - and the transmitters linked to that receiver are
indicated on the left side of the screen.
Σ-mode operation is similar - when selected, the system will show transmitters that are
connected to any receiver in the system. This is a quick way to make sure that all
transmitters are connected to the system by at least one receiver.

Test Mode – activates a test tone through the system so that
the user can carry out a constant-signal walkout test while
setting up and de-bugging the system. NOTE: No normal audio
operation is available when in the test tone mode, and the
mode must be exited in order for the system to operate
normally.
To enter and activate any of the TOOLS screen functions, press on the screen graphic for
the desired parameter. The display for the selected parameter will blink. Press the “SET”
button on the number pad to confirm the change.
To enter TEST MODE, press on the screen graphic at the “OFF” position under test mode.
The parameter will begin to blink. Enter the Audio-Technica phone number using the
key pad by pressing 330 686 2600 and then press “SET.” The display for TEST MODE will
now change to a green color and display “ACTIVE.” To immediately stop the TEST TONE,
press on the screen where it says “OFF.”
7. QUICK START
Using a shielded CAT 5 cable (may be used with up to 1,000 feet of cable per
channel) terminated with a standard RJ45 connector, plug the cable into the RJ45
input jack on the rear of at least one RP32 receiver. Connect the other end of the
CAT 5 cable to the RJ45 input jack on the rear of the MCU3224 main control unit.
You may connect up to 32 RP32 receivers by connecting them into the
corresponding channel output (1-32) found on the rear of the MCU.
You do not need to turn the RP on. It receives power via the CAT 5 cable
from the MCU 3224. The RP display should immediately light and display
the channel output number to which it has been connected on the MCU.
Apply power to the MCU3224 by connecting at least one IEC cable to AC wall
supply.
Studio Broadcast System
Page 23 of 26
Turn on one or both of the IEC power switches on the rear of the unit. The unit
fan will begin operation.
Press the front panel “power” button.
The power light(s) corresponding to the IEC cable input will be visible on the
front panel (one red and one blue), and the GUI screen will illuminate and
enter a “set-up” mode while the system is normalizing and preparing for
operation.
Once the system is available for operation, the GUI screen will display a
“HOME SCREEN.”
On the left-hand side of the screen, select the “Matrix” button:
This will allow the user to view and confirm that the desired number of RPs are
connected to the system with the desired channel # assignments.
Place 2 x AA batteries into a BP24 beltpack transmitter and slide the internal
power switch into the on position.
Studio Broadcast System
Page 24 of 26
Ensure that the BP24 system ID is the same as the System ID of the
MCU3224 (system will turn on in “default” system ID 1 for all devices). The
System ID is visible in all screens on the left-hand side of the display for
“navigation.”
Select the BP24 channel for operation (1 through 24)
Select the desired BP24 gain level
Ensure that the BP24 front surface is facing the RP32 front surface, and that they
are located somewhat in proximity to each other and roughly in a line-of sight
orientation. (Note that the distance of operation can be 90’ or more, depending
upon the particular operating environment, and line of sight operation is not
strictly or fully required due to positive effects of multi-path. However, with only
a single RP connected to the system, the “multiple coordinated receiver diversity”
is not in operation. Thus, line of sight and proximity are more important to stable
operation for initial set-up with only a single RP).
Studio Broadcast System
Page 25 of 26
Return to the MCU and select the “home screen”
The BP24 that has just been turned on should be shown in the display on the
channel number that you have set via the BP24 channel selection process.
Press the GUI on the displayed channel to highlight/select the channel of the BP24
that you are operating. This will allow all information about this particular channel
to be observed on the other screens. It also selects this particular channel for
output to the front-mounted headphone monitor jack.
You may now listen to your selected beltpack, or if you prefer, you can observe its
operation characteristics by selecting the “transmitter detail” button:
Repeat this process for as many RP32s and BP24s as needed for the application.
No frequency or channel coordination is required. Simply ensure that only one
beltpack channel is in operation for each channel (up to 24) in each system ID. (Do
not attempt to set 2 BP channels to the same channel # in the same system. The
system will not operate).
