COMMON SIGNAL TO ALL THE FOUR CHANNELS (4-CH MONO)
Make sure the amplifier is switched off before setting:
-
the BRIDGE A+B switch
10
to OFF
-
the BRIDGE C+D switch
11
to OFF
-
the switch
15
to A+B+C+D INPUT TO ALL OUTPUTS.
All the four inputs are mixed into a single signal sent to all the speaker and balanced
outputs.
This mode is useful to get a four-channel mono amplifier: for instance, the channel A
input is sent to all the 4 speaker outputs.
Each front panel level control affects its respective speaker output.
Minimum load impedance is 2 Ω per speaker output.
