1. MIC/LINE 1-2 IN
This is a XLR connector that accepts a XLR plug from any balanced or unbalanced microphone. The XLR
input is wired as follows:
Pin 1 = shield or ground
Pin 2 = + positive or "hot"
Pin 3 = - negative or "cold"
2. CH1-2 PHANTOM SWITCH
This switch activates (LED on) and deactivates (LED Off ) the phantom power on MIC 1-2 Inputs. Most
professional condenser microphones require phantom power, which is a lower DC voltage delivered to
the microphone on pin 2 and 3 of the XLR microphone connector. Dynamic microphones do not require
phantom power, however phantom power will not harm most dynamic microphones should you plug
one in while the phantom power is on. Check the manual of your microphone to find out for sure
whether or not phantom power can damage it.
3. MIC/LINE 3-4 IN
This is a female combo connector that accepts a XLR or a JACK plug from any dynamic balanced or
unbalanced microphone. The XLR input is wired as follows:
Pin 1 = shield or ground
Pin 2 = + positive or "hot"
Pin 3 = - negative or "cold"
The JACK input is wired as follows:
Tip = + positive or "hot"
Sleeve = shield or ground
4. MIC/LINE BUTTON
Press this button to select the input sensitivity of the respective channel 1 to 4: with the button up you
can select the MIC input signal, with the button down you can select the LINE input signal.
5. HIGH EQ
This potentiometer sets the HIGH TONE level of each input channel: if rotated clockwise it enhances the
highs, if rotated counter-clockwise it reduces the highs (in the centre position the response is flat).
6. LOW EQ
This potentiometer sets the LOW TONE level of each input channel: if rotated clockwise it enhances the
lows, if rotated counter-clockwise it reduces the lows (in the centre position the response is flat).
7. FX LEVEL
This potentiometer sets the level of the effect applied to the respective channel input.
8. CH 1-4 LEVEL
These potentiometers set the level of the respective channel input.
9. LINE STEREO 5/6 IN (JACK)
This is a ¼” (6.3mm) jack connector, which accepts a balanced or unbalanced line level input signal from
almost any source. When connecting a balanced signal, wire them as follows:
Tip = + positive or "hot"
Ring = - negative or "cold"
Sleeve = shield or ground
When connecting an unbalanced signal, wire them as follows:
Tip = + positive or "hot"
Sleeve = shield or ground
