3. General
DMS 700
The DMS 700 wireless microphone system is comprised of the DSR 700 stationary digital true-diversity
receiver, handheld transmitters DHT 700/C with the AKG C 5 microphone element and DHT 700/D with
the AKG D 5 microphone element and the DPT 700 bodypack transmitter. The receiver and transmitters
operate in a 155 MHz sub-band of each frequency set within the UHF band from 548 MHz to 865 MHz.
You can select the receiving frequency from pre-programmed frequency groups and sub-channels of your
receiver or set it directly in 25 MHz-increments. Both the handheld and the bodypack transmitter are set to
the parameters selected on the receiver via infrared transmission.
4. Setting Up
Prior to using your DMS 700, make certain that the transmitter and receiver are tuned to the same
frequency.
• Open the battery compartment cover (9).
• Insert the supplied battery into the battery compartment, aligning the battery according to the polarity
symbols. If you insert the battery the wrong way, the transmitter will not be powered.
• Close the battery compartment cover (9).
Connecting Antennas
The supplied ¼-wave antennas can be mounted quickly and easily and are suitable for applications where
a direct line of sight between the transmitter and the receiver antenna is available and a wireless
microphone system is to be used without a lot of installation work.
Remote Antennas
You should use remote-mounted antennas if the receiver’s position doesn’t allow the best reception.
Connect the remote antennas to the BNC sockets (13, 14) at the rear of the receiver. Use RG58 cable for
connecting the antennas. For details on antennas, accessories, and frequency planning support visit our
website at www.akg.com.
Antenna Front-mount Cable
Use the BNC extension cable (AKG part #0110E01890) for mounting the ¼-wave antennas on the front
panel.
Positioning the Receiver
Signal reflections off metal objects, walls, ceilings, etc. or the shadow effects of musicians and other
people may weaken or block the direct transmitted signal.
For best results, place the receiver or remote antennas as follows:
• Place the receiver/antennas near the performance area (stage). Make sure, though, that the
transmitter won’t be used within 10 ft (3 m) of the receiver. Optimum separation is at least 16 ft. (5
m). Check that you can see the receiver from where you will be using the transmitter. Shadow effects
caused by people or objects can disrupt the radio link.
• Place the receiver at least 5 ft. (~1.5 m) away from any large metal objects, walls, scaffolding,
ceilings, etc.
• You can use the receiver either free-standing or mounted in a 19" equipment rack.
• If you install one or more receivers into a 19" rack, either mount the supplied antennas on the
receiver front panel(s) or use remote antennas. This is the only way to ensure optimum reception
quality.
DMS 700 V1.00 8
Connecting the Receiver to a Mixer/Amplifier
Analog output
You can connect the receiver’s two analog XLR (16, 19) and two analog ¼ Inch/6.3mm jack (17, 20)
outputs at any time. Using the receiver’s DSP Menu the output level can be adjusted as needed.
Connect the audio output to the desired input:
• BALANCED XLR-output - microphone input: set the output level switch to "-30 dB".
• BALANCED XLR-output - line input: set the output level switch to "0 dB".
• UNBALANCED 1/4-inch output - unbalanced 1/4" microphone or line input jack.
Digital Output
Use the AES3 digital balanced XLR (23) output to connect audio signals of both receivers to an AES3
digital input. The built in A/D converter supports a sampling rate of 48 kHz. You can connect an external
48 kHz clock generator at the Wordclock IN (22) BNC socket to synchronize all your digital signals. The
receiver will automatically detect an external 48 kHz clock and will use this clock for the A/D conversion.
You can check the Wordclock state in the Channel Information window.
Ground Lift (15, 18)
This switch allows you to remove hum caused by ground loops. To open the chassis ground connection,
press the GROUND LIFT button to the LIFT position. You can check the GND LIFT state in the Channel
Information window.
Connecting the Receiver to Power
Check that the AC mains voltage stated on the rear panel is identical to the AC supply voltage
available where your system will be used. Using the power supply with a different AC voltage may
cause damage to the unit.
Plug the power cord into the AC IN socket (24) on the receiver’s rear panel and plug the power cord into a
convenient power outlet
Silent Mode
We recommend setting the carrier frequency in SILENT mode only (RF OFF). To engage SILENT mode,
push and hold the MUTE switch (2) while turning on (6) the transmitter. This is the only way to make sure
you won't go "on air" on a frequency that is not allocated or coordinated and risk "jamming" or interfering
with some other RF device or wireless system.
Key Lock / Unlock of the Receiver
The receiver is electronically locked so that you won’t make any unintended adjustments.
The "LOCK" label (D) is shown on the display. To enter SETUP mode, press and hold the SETUP control
(5) until the "LOCK" label disappears. After approximately 4 minutes with no action, the receiver will
automatically switch into the LOCK mode.
Optional external MUTE switch
The optional RMS 4000 Remote Mute Switch allows muting of the transmitter if it is mounted in a position
where it is difficult or impossible to use the "on-board" MUTE switch.

Quicksetup
The DSR 700 is designed for use in large multi-channel systems. To find intermodulation-free carrier
frequencies quickly and easily, we recommend using the QUICKSETUP function to find all required
channel from the same Group within the same Preset. To start the QUICK SETUP, push the START
SETUP Menu, set the required channel number and if frequency ranges and start the scan. The scan
procedure can take up to one minute. The CHANNEL LIST shows you the free channels in a user-friendly
list. To assign and synchronize a free channel to the receiver you can use the channel button. Use the
CONTINUE SCAN sub-menu to search for other frequencies
Channel Menu
All channel-specific parameters like GROUP/CHANNEL, FREQUENCY, NAME, TRANSMISSION
POWER, ENCRYPTION and MUTE LOCK can be set and adjusted manually.
Group and Channel
The DSR 700 receiver provides frequency groups with specially-calculated frequencies. In the
GROUP/CHANNEL menu you can set and synchronize a channel(frequency) manually. Make certain that
all selected channel are from the same Group within the same Preset. To find free channels we
recommend using the QUICKSETUP function.
Frequency
Using the FREQUENCY sub-menu, the DSR 700 receiver allows frequency adjustments in 25-kHz-steps.
Name
You can enter any name (the name of performer or instrument, etc) for each channel.
Transm. Power
The TRANSM.POWER sub-menu lets you adjust the RF output power of the synchronized transmitter.
Encryption
If you turn on the encryption function, the receiver will calculate a unique key every time that you
synchronize the transmitter. The receiver uploads the key during the infrared synchronization with the
transmitter. You can not readout the encryption key and it is not possible to set two transmitters to the
same key! If you have to work with a backup transmitter you must turn off the signal encryption.
Mute Lock
The MUTE LOCK deactivates the mute button on the transmitter. You can override the transmitter if you
set the MUTE LOCK at the receiver afterwards!
Synchronization
During the infrared synchronization the receiver overwrites all previously-set values (Group/Channel,
frequency, name, transmission power, encryption key, and mute lock) of the transmitter.
To program the transmitter to previously-set values, start the transmitter synchronization in the receiver
menu and point the infrared sensor (4) on the transmitter at the infrared emitter (8) on the receiver from a
distance of 4 inches/10 cm max.
AUDIO Menu
DSP
The built-in digital signal processor allows you to control your audio signal directly in the receiver with
common processing features. The following dynamics processors are available:
• Input gain (gain)
• Low cut (frequency)
• 3-Band Equalizer (low gain, mid gain, mid-frequency, high gain)
• Compressor (threshold, ratio, gain, attack & release time)
• Limiter (threshold)
All values can be stored with a freely-selectable name in one of the nine profiles.
Attention! Profiles affect the settings on both channels! Changes effect both channels and all
values stored in profiles previously will be overwritten!
DMS 700 V1.00 16
DSP Button
The DSP button provides a bypass function for LOW CUT, EQ, COMPRESSOR and LIMITER for both
channels separately.
Output Gain
For matching the receiver’s BALANCED output level to the input gain of the connected equipment . If you
are using the MIC input of your mixer, the LINE 0 dB level might overload the input. In that case, set the
receiver’s output gain to MIC -30 dB to reduce the output level. The UNBALANCED line output level is not
adjustable
Environment Scan
The Environment Scan function converts the receiver into a spectrum analyzer. The UNLIMITED SCAN
automatically searches the receiver's entire frequency band ±6 MHz for active radio frequencies. The
LIMIT SCAN provides the possibility of scanning only a part of the receiver’s frequency range. During the
search, the audio output is muted and the display shows a frequency graph. You can navigate (CW, CCW)
and zoom (push) through the graph by using the SETUP Wheel.
Rehearsal – Sound Check
The Rehearsal Scan function converts the receiver to an RF recorder to check the RF level in your
reception area. Start this function and walk around the desired coverage area with the synchronized
transmitter. The graphic display shows you the received signal level in time. To mark some positions, you
can use the transmitter MUTE button to set markers on the receiver display. You can navigate (CW, CCW)
and zoom (push) through the graph by using the SETUP Wheel. The received signal level should never
drop below -85 dBm. You can optimize signal reception by changing the position of the connected
antennas.

Utilities Menu
Status
The STATUS sub-menu lets you activate a visual warning that alerts you when there are problems with
selected critical system conditions. If one of the selected conditions occurs, the LED ring around the
SETUP control will change from green to red and a warning message will appear on the display that
describes the problematic condition. The warning messages appear in the order of priority. Depending on
the warning, a big information message lasts only for 5 sec. visible. A smaller information message stays
active until it is confirmed.
The selected warning functions are active in LOCK and ACTIVE modes. To delete a warning message
from the display, press the SETUP control briefly.
Status Information in order of priority
LOW BAT
Transmitter’s remaining battery capacity is low. Permanent big warning and red LED ring.
AF CLIP
Audio overload of the transmitter’s A/D converter. Reduce the audio input level. Red LED ring and big
warning lasts for 5 sec. or as long as the condition occurs. Small warning in the main window lasts until
it is deleted.
RF LOW
The field strength of the received RF signal is so low that the receiver’s audio output is muted to prevent
unwanted noise. Red LED ring and big warning for 5 sec. or as long as occur. Small warning in main
window as long as not deleted.
ANT ERROR
The same antenna has been active for at least one minute. Check if antenna cable is broken or wrong
connected. Red LED ring and big warning for 5 sec. Small warning in main window as long as not
deleted.
Country
When you turn the receiver on for the first time, the receiver will ask you to set a country.
Normally you should use SD (Standard), EU (EUROPE) or US (USA). Only for special countries does the
internally-stored frequency presets have to be adjusted. In that case, these countries can be set.
Otherwise, please use the SD setting.
Display-Mode
This menu lets you change the display appearance. You can choose from 4 different displays:
MAIN: GROUP/CHANNEL: FREQUENCY: NAME :
Display Contrast
The Display Contrast sub-menu allows you to adjust the contrast of the display for use in different lighting
conditions
Factory Reset
The Factory Reset sub-menu allows you to reset all parameters to their default values.
Info
The INFO sub-menu lets you call up software and hardware information about your receiver and the
synchronized transmitter.
