ONE BRIDGED OUTPUTS PAIR AND TWO INDIPENDENT CHANNELS
Make sure the amplifier is switched off before setting:
- BRIDGE A+B switch to ON;
- BRIDGE C+D switch to OFF;
- switch [14] to STEREO.
CHANNELS A AND B: these channels are bridged and work with the same input signal (channel A input). The result is
a doubling of the output voltage in order to get a double power (on a double impedance load).
The output level is adjusted only by the channel A front panel control (turn fully counterclockwise the channel B control).
CHANNELS C AND D: these two channels are independent, and each front panel level control affects its respective
speakers’ output.
Do NOT connect the channel B speakers’ output. Minimum load impedance is 4 Ω on channel A speakers’ output.
Pay attention to the SPEAKON wiring: pin 1+ positive, pin 2- negative. Minimum load impedance is 2 Ω on speakers’
output C and D.
As alternative wiring, it is possible to use just a SPEAKON connector (by using all the four pins) for the channels C and D.
It is alternatively possible to use channels A and B separately (BRIDGE A+B switch set to OFF) and channels C and D
bridged (BRIDGE C+D switch set to ON), by considering a mirror image of the description and connections here above
explained.
