The power supply unit has been set from the factory to operate at the voltage required for your part of the
world. However, it’s important to double-check this in order to ensure no damage will occur to the unit if power
is applied while the setting is incorrect.

The pow
er switch is located on the front panel of the Power Supply Unit. Switching the rocker switch to the I
position turns th
e mains power on. Switching the rocker switch to the O position turns the mains power off.

connections be made before applying power to the RCU. Simply plugging the 2.1mm barrel connector into the
DC power jack turns the power
on. The m802 RCU is rated for 6.0-7.5V / 0.5A DC. (+) is in the center and (–) is
on the outside sleeve.

Standard microphone input connections are made via female XLR connectors with pin 2 positive, pin 3 negative
and pin 1 ground. 48V phantom power is supplied on pins 2 and 3. DPA® 130V microphone connections are
made via the female 4 pin XLR connectors with audio on pin 4, 130V on pin 3 and ground on pin 1.
On standard m802 preamp channels, two male XLR output connectors are available with pin 2 positive, pin 3
negative and pin 1 ground. (There is one male XLR output connector available on 130V DPA cards.) An ad-
ditional set of parallel outputs is provided with a 25 pin D-sub connector
NOTE:
this output is not available if the optional A/D converter module is installed. All output connectors can be used
simultaneously.
If the output is to be used unbalanced, pin 1 should be connected to signal ground and pin 2 to signal hot. Due
to the nature of the balanced output stage, pin 3 should be left open for unbalanced operation (See CABLE
DIAGRAMS p. 21). Note: This will provide a signal of positive absolute polarity when the preamplifier is being
used with a microphone which produces a positive voltage on pin 2 with positive air pressure on the front of the
diaphragm. While a vast majority of microphones conform to this standard a few do not. Use the phase reverse
switch to compensate if necessary.
DiGital aUDio connectionS
If the optional A/D converter module is installed, multiple digital outputs are available. The routing of the pre-
amp outputs to the A/D converter is fixed. Each preamp channel feeds the corresponding converter channel
(1-8). The DB25 pin provides 8 stereo AES outputs, which can be configured for single or dual wire operation.
