d. Speaker - Socket
• 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.
e. 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!
f. 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.
g. 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.
h. Connection with the Mains
Have a qualified technician carry out the electric connection!
The wiring of the connection cables is as follows:
The device must be earthed!
