8. Speaker terminals
Connect your speaker wires on these euroblock terminals. Note that minimum load impedance is
4
Ω
in 2 channel mode and 8
Ω
in bridge mode.
9. Earth lift switch
In case you should have a ground loop problem, push this switch to lift the audio inputs from ground.
Please avoid ground loop problems and use this switch only in case of emergency.
This is not a miracle problem solving switch
Note: you can use all 8 channels from one stereo source by pushing the 1 to 3/2 to 4, 3 to 5/4 to 6 and
5 to 7/6 to 8 switches. In case you link channels, don’t connect any sources to the linked channels,
e.g. if you link 1 to 3/2 to 4 you have to apply your input channel to inputs 1 and 2 and keep
inputs 3 and 4 free.
Only the levelcontroller and highpass filter switch of the odd numbered channel will be in use
In bridge mode, only the input to the odd numbered channel will be heard. Only the levelcontroller and
highpass filter switch of the odd numbered channel are in use.
Also take a look at the signal flow chart on top of the amplifier for more clarity.
