This control adjusts the amplifier’s gain for channel 2.
7 SDP slot CH1/bridge
Insert SDP modules for channel 1 or bridge mode operation in this connector
8 SDP slot CH2
Insert SDP modules for channel 2 in this connector
9 Parallel mode switch
When this switch is set to the right hand or ‘ON’ position, the signal on the channel 1 input connector is also fed to the channel 2
input circuitry. In this mode each channel uses its own SDP module and gain control.
10 Bridge mode switch
When this switch is set to the right hand or ‘ON’ position, the amplifier operates in bridge mode.
11 SDP limit CH1
This LED indicates limiting of the channel 1 SDP module.
12 SDP limit CH2
This LED indicates limiting of the channel 2 SDP module.
