2. Control Elements

1. MIC Use this balanced XLR jack to connect microphone to the mixer.
• The phantom power required for condenser mics can be activated with
+48V PHANTOM switch.
Channels 1-4 feature an additional line input on a balanced 1/4" jack.
2.
3. Use the GAIN control to adjust the input gain. This control should always be
turned fully counterclockwise when ever you connect or disconnect a signal
source to one of the inputs.
4. In addition, the mono channels are equipped with a steep LOW CUT filter
(slope at 18 dB/oct, -3 dB at 75 Hz) designed to eliminate unwanted low-
frequency signal components.
5-7.
The upper (HIGH) and the lower band (LOW) are shelving filters that
increase or decrease all frequencies above or below their cut-off frequency.
The cut-off frequencies of the upper and lower band are 12 kHz and 80
Hz respectively. The (MID) band is configured as a peak filter with a center
Frequency of 2.5 kHz.
8.
The PK LED's of the mono channels illuminate when the input signal is
driven too high, which could cause distortion. If this happens, use the GAIN
control to reduce the preamp level until the LED does not light anymore.
9. FX sends enable you to feed signals via a variable control from one or
more channels and sum these signals to a bus. The bus appears at the
console's FX sent output and can be fed from there to an external effects
device. The return from the effects unit is then brought back into the
console on the stereo channels. Each FX send is mono and features up to
+10 dB gain.
10.
The PAN control determines the position of the channel signal within the
stereo image. Turning PAN knob left will send Audio to the left side of
MASTER output and vice versa.
11.
The LEVEL control determines the level of the channel signal in the main
mix.
12. LINE IN Each stereo channel has two balanced line level inputs on 1/4" jacks
for left (L/MONO) and right (R) channels. If you use only the (L/MONO)
jack , same sound is output from both Left and right speakers.
13. The EFF SEND connector outputs the signal you picked up from the
individual channels using the EFF SEND controls. You can connect this to
the input of an external effects device in order to process the EFF bus'
