Connecting The Receiver To A Mixer/Amplifier; Ground Lift (15, 18); Connecting The Receiver To Power; Silent Mode - AKG DMS 700 User Manual

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:
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.
