Electrocompaniet AW100DMB - Manual (Page 5)

Single-ended (normal) input and operation
Upon arrival, the amplifier is set for single-ended use with a shorting plug in the ne-
gative RCA input. This will short the negative (-) input of the amplifier to ground. With
shorting plugs in position, the amplifier is ready to be connected in a normal way with
a single ended preamplifier.
Balanced XLR input and operation
The balanced mode can only be used if the preamplifier has a balanced output. In
order to use the balanced XLR- input, turn off the amplifier, and remove the
shorting plugs from the negative (-) RCA inputs. Use an XLR interconnect with
GND on pin 1, + on pin 2 and - on pin 3.
Balanced RCA input and operation
The balanced mode can only be used if the preamplifier has a balanced output. Be
sure the amplifier is turned off. Remove the shorting plugs. Use 2 single (1 stereo)
interconnect cables from the preamplifier to the power amplifier, connecting + and -
outputs from the preamplifier to the + and - inputs of the corresponding channel on
the amplifier.
Make sure the + and - are not interchanged, as this will cause the system to operate
out of phase, with very poor bass response as a result.
Operating instructions:
How to turn on your system
You should always turn on your equipment in this order: Signal source devices (CD,
tuner, etc) and preamplifier are turned on first. Allow 30 seconds of preheating before
you turn on your power amplifier.When turning your system off, you should start by
switching off your power amplifier, preamplifier and finally your signal source
devices.
After switching on the power amplifier, there will be a 5 seconds delay before the
speakers are connected. This will prevent large turn on/off transients to reach the
speakers.
