If there is no external control voltage, the output
voltage (10 V) provided at the screw terminals* (7)
can be used. For this purpose it is recommended to
use potentiometers with a value of 10 kΩ and a
linear characteristic (e. g. MONACOR VCA-202RN).
Connect the potentiometers according to fig. 3.
If a stereo source is connected, the control
inputs (6) of both channels have to be connected in
parallel according to fig. 4.
4) Finally connect the plug of the mains cable (3) to a
mains socket (230 V~/50 Hz).
5 Operation
1) Prior to switching on, the control voltages should be
set to 0 V to prevent loud switching noise.
2) Switch on the unit with the POWER switch (1). The
red POWER LED (2) lights up.
3) Switch on the connected units, always switch on the
power amplifier for the speakers last.
4) When switching off the system, always switch off
the power amplifier first.
5.1 Adjusting the output level
The output level is adjusted with a DC voltage. The con-
trol range is between 0 and 10 V, at 0 V there is no out-
put level. There is a linear rise of the output level ac cor-
d ing to the control voltage. The maximum amplification
is 1 (0 dB) and appears at a control voltage of 10 V.
