• MONO MODE
Ensure the amplifier is switched off, then set the
MODE
selector to
PARA
.
In mono mode, both channels are linked to input 1 (therefore receiving the same signal).
Each front panel level control affects the respective output, allowing you to set (if necessary) different
levels.
Minimum nominal load impedance is 2 Ω per output.
Loudspeakers can be connected to either the SPEAKON output 1 or 2.
Note
that only the amp. inputs are connected in parallel. This is NOT an output parallel mono mode.
Never connect either positive or negative output terminals in parallel !
As alternative wiring, the amplifier output 2 is also available on the SPEAKON connector of the
output 1 (pins: 2+ positive, 2– negative).
• BRIDGE MODE
Ensure the amplifier is switched off, then set the
MODE
selector to
BRIDGE
.
In ‘bridge’ mode (mono), both amplifier channels work with the same input signal, but with
inverse phases. The result is a doubling of the output voltage in order to get a double power (on a
double impedance load).
Both level controls (on the front panel) must be set to the same value (it is advisable to set them
to the max. level: 0 dB).
Only the CH1 input is to be used; only the amplifier output 1 is to be connected (pay attention to the
SPEAKON pins: 1+ positive, 2+ negative).
Minimum nominal load impedance is 4 Ω.
