Rear panel features
(1) Line inputs
Individual channel inputs for use with multi-channel preamps or dedicated
sources.
(2) Global input
Allows an individual input source to be shared across any or all channels.
(3) Global loop out
Allows global inputs to be looped out to other amplifiers or devices.
(4) Global DIP switch
Allows distribution of the audio signal from the Global In (L and R) to multiple
amplifier channels in a configuration of your choice.
(5) Bridge DIP switch
Allows the combining of two channels to create a single bridged output channel.
The single combined output channel is driven at 160 W at 8Ω. This can be very
useful when more power is needed in particular areas, such as outdoor
environments. Note: 8Ω speakers must be used when bridging channels.
(6) Gain control
Allows individual control of the maximum output for each pair of amp channels.
(7) 12V trigger
Powers on the amplifier from Standby mode into full power mode when triggered.
(8) Global gain
Allows control of the maximum output of all channels that have been set to Global
mode (i.e., Global DIP switches for those channels are ON).
(9) Speaker outputs
Individual Phoenix-style terminal connectors (included) for each speaker.
(10) Fan
Rear location fan with front intake allows for direct stacking of the amplifier with
other equipment, greatly reducing rack space usage.
(11) Power connector
