SPEAKER TERMINAL CLAMPS CHANNEL A AND B
Connection of speakers or speaker systems with a total impedance of at least 4 ohms per channel.
Connect the positive pole (+) of the speaker cable to the red terminal clamp (+) and the negative pole (-) of
the speaker cable to the black terminal clamp (-) of the respective channel. Optionally, speaker cables with
banana plugs can also be used.
In bridge mode BTL (bridge tied load), the red Channel A terminal clamp must used as the positive pole (+)
and the red Channel B terminal clamp must be used as the negative pole (-).
IMPORTANT: In bridge mode, the total impedance of the connected speaker system must not be less than 8
ohms.

GROUND-LIFT SWITCH
Used to avoid ground loops. In LIFT position, the connection between the housing and the signal ground is
interrupted.
7
MODE SWITCH
In STR position (stereo mode), output stages A and B operate independently. Both stereo signals and entirely
different signals can be amplified via Channel A and B.
In BTL position (bridge mode), output stages A and B are connected to a more powerful mono output stage.
IMPORTANT: In bridge mode, the total impedance of the connected speaker system must not be less than 8
ohms.
