FUSE HOLDER/IEC MAINS RECEPTACLE
The console is connected to the mains via the cable supplied, which meets the 

required safety standards. Blown fuses must only be replaced by fuses of the 

same type and rating. The mains connection is made via a cable with IEC mains 

connector. An appropriate mains cable is supplied with the equipment.

POWER switch
Use the POWER switch to turn on the mixing console. The POWER switch should 

always be in the “Off” position when you are about to connect your unit to 

the mains.
To disconnect the unit from the mains, pull out the main cord plug. 

When installing the product, ensure that the plug is easily accessible. If mounting 

in a rack, ensure that the mains can be easily disconnected by a plug pull or by an 

all-pole disconnect switch on or near the rack.

PHANTOM switch
The PHANTOM switch activates the phantom power (necessary to operate 

condenser microphones) on the XLR sockets. The red +48 V LED illuminates 

when phantom power is on. As a rule, dynamic microphones can still be used 

with phantom power, provided that they are wired in a balanced configuration. 

In case of doubt, contact the microphone manufacturer!

You will need a large number of cables for the various connections of the console. 

The illustrations below show the wiring of these cables. Be sure to use only 

high-grade cables.

The footswitch connects both poles momentarily

6.1.1  Audio connections
Please use commercial RCA cables to wire the 2-track inputs and outputs.
You can, of course, also connect unbalanced devices to the balanced input/

outputs. Use either mono plugs, or use stereo plugs to link the ring and shaft 

(or pins 1 & 3 in the case of XLR connectors).

For unbalanced use, pin 1 and pin 3 

have to be bridged

1 = ground/shield

2 = hot (+ve)

3 = cold (-ve)
