•
Your amplifier is equipped with 4-pole, lockable speaker sockets. Turn the plug to the right to lock the
connection. To unlock: pull the unlock button, turn to the left and pull the plug out of the socket.

Choosing Appropriate Connection Cables
•
Use sufficiently thick cables to connect the speaker system. Thin cables may heat up and cause significant
power loss and loss in sound quality.
•
For all speaker systems up to 400W, we recommend a cable diameter of 2.5mm²; for all other speaker cables
it's 4mm².
•
The high damping factor of your amplifier ensures a clear sound reproduction. Unnecessarily long and thin
cables will influence the damping factor and thus the low frequencies in a negative way. In order to safeguard
good sound quality, the damping factor should be around 50. The longer a cable, the thicker it should be.
Example: A damping factor of 200 is reduced to 47 (8 ohms) when using a diameter of 2.5mm² speaker cable
of 10m in length. The power loss at 8 ohms is 1.63%, at 4 ohms it’s 3.25% and at 2 ohms it’s as
much as 6.5%.
•
The maximum cable length is 30m!

Installing the Speaker Cables
•
Connect the cable of the first speaker system with speaker outputs CH-1 and output CH-2 of the amplifier. The
signal will be transmitted to the individual speaker systems.
•
Always handle the cables with care and protect them from damage in transit.
•
Make sure no one can trip over the cables. Always fix them with an appropriate tape.
•
Both cables should be of the same type and length.
•
Do not loop the cables.
•
Always install the cables far away from power cables (never alongside them).
•
Never put heavy objects like speaker systems, flight cases etc. on cables.
•
Always roll cables loosely round the elbow.

Ground Lift Switch
This switch allows the signal ground or chassis ground to be separated in case of a ground conflict. For highest
safety of the equipment, it is recommended to keep the ground lift switch in the GND FLOATING position. In case
of a ground conflict set the ground lift switch to GND LIFT.

Connection with the Mains
Be careful of the high voltage at the screw terminal. Switch off the amplifier before
connecting the device.
Have a qualified technician carry out the electric connection!
