DIP SWITCH SETTING

Each pair of amplifiers have their own set of four DIP switches. The function of each switch is described below:
AMP ON: (ON is the factory default setting for all amplifier pairs)
Amplifier pairs with DIP switch ‘AMP’ set to ‘ON’, have the remote Master and Channel switching of
the amplifier audio mute on/off feature disabled. When remote amplifier audio muting is desired by
either the Master or ‘Local’ Channel control input, the ‘AMP’ switch must be set to the ‘Off’ position.
SENSE OFF: (OFF is the factory default setting for all amplifier pairs)
Amplifier pairs with DIP switch ‘SENSE’ set to ‘ON’, have the remote Master and Channel switching of
the amplifier audio mute on/off feature disabled. Amplifier pairs set to use ‘SENSE’ will mute
automatically after a delay of three minutes once no audio signal has been detected. The sense circuit
monitors the amplifiers selected audio, i.e.. ‘Local’ or ‘BUS’ mono or stereo. When remote amplifier audio muting
is desired by either the Master or ‘Local’ Channel control input, the ‘SENSE’ switch must be set to the ‘Off’
position. When the AMP ON feature is desired or automatic muting of the amplifier pairs is not desired, or if the
audio signal is erratic, the ‘SENSE’ switch must be set to the “Off’ position.
L + R: (OFF is the factory default setting for all amplifier pairs)
Amplifier pairs with DIP switch ‘L + R’ (mono) set to ‘ON’, have the sum of the selected audio inputs,
i.e.. ‘Local’ or ‘BUS’, processed into a composite mono signal source for both amplifier channels.
When mono is not desired, or independent channel amplification of the amplifier pairs is necessary,
the ‘L + R’ switch must be set to the ‘Off’ position
BUS: (OFF is the factory default setting for all amplifier pairs)
Amplifier pairs (channels 1-2, 3-4 and 5-6), with DIP switch ‘BUS’ set to ‘ON’, have their inputs
sourced from the audio signals present at the BUS inputs. When the BUS feature is not desired and
the amplifier pair is to be sourced at the ‘Local’ audio inputs, the ‘BUS’ switch must be set to the ‘Off’.
