DMS
700 4 Setting Up
• Prior to using your DMS 700, make certain that the transmitter and receiver are tuned to the same frequency.
Inserting Batteries into the Transmitter
1. Open the battery compartment cover (9).
2. 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.
3. 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.
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 (14, 15) on the receiver rear panel.
Use RG58 cable to connect 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 (13).
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.
Connecting the Receiver to a Mixer/Amplifier
Analog output
You can connect the receiver’s two analog XLR (17, 20) and two analog ¼”/6.3mm jack (18, 21) outputs at any time. Use the receiver’s AUDIO Menu to adjust the output level as needed.
• Connect the audio output to the desired input: a) BALANCED XLR-output - microphone input: set the output level switch to "-30 dB".
b) BALANCED XLR-output - line input: set the output level switch to "0 dB".
c) UNBALANCED 1/4” output - unbalanced 1/4" microphone or line input jack.
Digital Output
For details on the AES-EBU output visit www.akg.com.
• Use the AES-EBU digital balanced XLR (24) output to feed the audio signals of both receivers to an AES-EBU digital input.
The built-in Wordclock generator supports a sampling rate of 48 kHz. You can connect an external 48 kHz clock generator to the Wordclock IN (23) BNC socket to synchronize all your digital signals.
DMS 700_2_Quad Manual_F031103 21.03.2011 15:12 Uhr Seite 9
4 Setting Up
The receiver will automatically detect an external 48 kHz clock and then use the external clock.
You can check the Wordclock status in the Channel Information window.
DMS
700
Ground Lift (16, 19) This switch allows you to remove hum caused by ground loops.
• To open the chassis ground connection, set the GROUND LIFT switch to the LIFT position.
You can check the GND LIFT status in the Channel Information window.
• 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.
Connecting the Receiver to
Power
L
Important!
• Plug the power cord into the AC IN socket (25) on the receiver’s rear panel and the other end of the power cord into a convenient power outlet.
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.
Transmitter SILENT Mode
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 SELECT control (5) until the "LOCK" label disappears.
After approximately 4 minutes with no action, the receiver will automatically switch into LOCK mode.
• To disable the automatic LOCK function, call up the AUTOLOCK sub-menu and select "OFF".
Receiver LOCK Mode
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.

700 9 Function Description
QUICK SETUP The DSR 700 has been designed for use in large multi-channel systems. To find intermodulationfree and clean carrier frequencies quickly and easily, we recommend using the QUICK SETUP function to find all required channels.
1. To start QUICK SETUP, select the START SETUP menu, set the required number of channels as well as the required frequency ranges and start scanning.
The scan procedure can take up to one minute. The CHANNEL LIST shows you clean channels in a user-friendly list.
2. To assign and synchronize a clean channel to the receiver you can use the channel button.
3. Use the CONTINUE SCAN sub-menu to search for other frequencies.
CHANNEL Menu All channel-specific parameters such as GROUP/CHANNEL, FREQUENCY, NAME, PT GAIN, TRANS-
MISSION POWER, ENCRYPTION and MUTE LOCK can be set and adjusted manually.
GROUP / 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 channels are from the same Group within the same Preset. To find clean channels we recommend using the QUICK SETUP function.
FREQUENCY The FREQUENCY sub-menu allows frequency adjustments in 25-kHz increments.
NAME You can enter any name (the name of a performer or instrument, etc) for each channel.
PT GAIN This sub-menu allows you to match the audio input gain of the DPT 700 bodypack transmitter to the microphone connected to the audio input.
TRANSM. POWER The TRANSM.POWER sub-menu lets you adjust the RF output power of the synchronized transmitter.
ENCRYPTION
For details, visit www.akg.com.
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 process.
You cannot read out the encryption key and it is not possible to set two transmitters to the same key.
Note: • For transmitters with firmware versions lower than 2.0, select 32-bit encryption. (These transmitters will not function with 512-bit encryption.)
• For transmitters with firmware version 2.0 and higher, you can select 512-bit encryption for the highest possible security.
• If you use a backup transmitter you must turn off the signal encryption function.
MUTE LOCK MUTE LOCK deactivates the mute button on the transmitter. The user of the synchronized transmitter cannot mute the audio signal locally.
SYNCHR. TRANSMITTER During the infrared synchronization process the receiver overwrites all previously selected transmitter settings (Group/Channel, frequency, name, bodypack gain, transmission power, encryption key, and mute lock).
• To program the transmitter to the settings you selected on the receiver, start the transmitter synchronization from 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.

The Environment Scan function turns the receiver into a spectrum analyzer. UNLIMITED SCAN automatically searches the receiver's entire frequency band ±6 MHz for active radio frequencies. LIMIT
SCAN scans only 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 using the SELECT control.
REHEARSAL –
Sound Check
The Rehearsal Scan function converts the receiver to an RF recorder to check the transmitter RF level in your reception area. Maximum recording time is four minutes.
1. Start this function and walk around the desired coverage area with the synchronized transmitter. The graphic display indicates the received signal level as it varies over time.
2. 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 using the SELECT control.
• The received signal level should never drop below -85 dBm. You can optimize signal reception by changing the position of the connected antennas.
