SETTING INTO OPERATION
Rack Installation
Install the unit on a plane surface or in your rack. For 19" (483 mm) rack installation, 1 unit is required. When
mounting the unit into the rack, please make sure that there is enough space around the unit so that the
heated air can be passed on. Steady overheating will damage your unit. You can fix the unit with four screws
M6 in the rack.
Making the Connections
Switch off the mixer prior to connecting any units or to changing any existing connections.
1
Connect stereo units with line level (e.g. CD players) to the RCA inputs
SOURCE 1-3
(white jack = left;
red jack = right).
2
It is possible to connect both microphones (balanced or unbalanced) and mono units with line level to
the inputs of the mono channels
MIC 1-3
. For phantom powered microphones you can switch on a 12 V
phantom power via the dip switches (see chapter 6).
Caution!
If the phantom power is switched on, no unbalanced microphones or units with line level must be
connected to the corresponding inputs. Otherwise, these microphones and units may be
damaged.
3
An external effects unit can be inserted via the jacks
SEND
and
RETURN
. Connect the mono output
(6.3 mm jack)
SEND
to the input and the stereo input
LEFT/RIGHT RETURN
to the output of your
external effects unit.
4
A PA amplifier for speakers or a subsequent unit with line level can be connected to the 6.3 mm jacks
LEFT OUT
and
RIGHT OUT
.
5
For sound recordings, connect the recording unit to the RCA output
REC OUT
. The recording level is
independent of the position of the master control.
6
Finally, connect the supplied power supply cable to the corresponding input and the mains plug to an
outlet.
Basic Setting
1
Prior to switching on, turn the master control to zero to avoid a possible switching-on noise.
2
Switch on the unit with the power switch. The power indicator on the front panel lights up. Then switch
on the connected units, always switch on the PA amplifier for the speakers last. When switching off the
system, always switch off the PA amplifier first.
3
Turn up the master control so that the mixing ration of the connected audio sources can be adjusted in
an optimum way.
4
With the input selector
MIC/LINE
adjust the mono channels
MIC 1-3
to the connected sources:
• button not pressed: input switched to microphone level
• button pressed: input switched to line level
5
Adjust the desired volume ratio with the level controls of the stereo channels and the mono channels.
The overload indication
CLIP
should not light up or only light up shortly during signal peaks. If it lights
permanently, reduce the level with the channel level control.
6
To mix the signal of an external effect unit to the mono channels, press the button
FX LOOP
and adjust
the signal amount with the control
FX LOOP
.
7
Adjust the desired sound with the tone controls. By adjusting the tone controls, the high frequencies
(control
HIGH
) and the low frequencies (control
BASS
) can be boosted or attenuated. With the controls
in mid-position, the frequency response is not affected.
8
Adjust the definite level of the stereo master signal with the master control.
