BUS* AUX* LINE Switch
Allows each channel to play a variety of dierent inputs. Depending on the switch
position the channel amplies the signal connected to the BUS input, the AUX
input, or its own LINE input.
R R + L L Switch
When either a BUS or AUX input is selected, this switch is used to direct the channel
to play the left signal from the input “L” or the right signal from the input “R”, or a
combined right and left signal from the input “R+L”.
Bus Input
Allows the signal from a source to be distributed to any of the 12 channels on the
amplier.
Auxiliary Inputs
Allows the signal from a secondary source to be distributed to any of the 12 channels
of the amplier.
Power Mode Selection
There are three ways to turn the amplier on and o. Use the following list to
decide which mode will work best for your application. See Diagram 3 below.
1. Constant
Use this selection when you wish to manually turn the amplier on and o by
using the front mounted power button.
2. Trigger
Use this selection if you wish the amplier turn on when it receives voltage
(12-15V A/C or D/C) from an external source and turn o once that voltage has
stopped. Some components have voltage outputs that are designed for this use.
In addition there are devices that can be used as part of an automated system
that will provide voltage to enable the mode. The voltage source must be
connected to the trigger-input jack on the back of the amplier.
3. Audio Sense
Use this selection when you want the amplier to turn on when the amplier’s
main input receives an audio signal. At the moment that either the left or right
input jacks receive a signal the amplier is turned on. Once the signal stops the
amplier waits 3 minutes and then turns o.
