FUNCTIONS

Level Controls – Allows any of the channels to be adjusted independently to raise or lower the output of each channel.

BUS(L.R)*LINE Switch – Allows each channel to play a variety of different inputs. Depending on the switch position the channel amplifies the signal connected to the BUS input and its own LINE input. Bus switch also includes a L and R position which is used to direct the channel to play the left signal from input “L” or right signal from input “R”.

POWER MODE SELECTION

There are three ways to turn the amplifier on and off:

1. Manual – Use this selection when you wish to manually turn the amplifier on and off by using the front power button.

2. Trigger – Use this selection to turn on the amplifier when it receives voltage (3-24V A/C or D/C) from an external source and turns off once that voltage has stopped. The voltage source must be connected to the trigger-input jack on the back of the amplifier.

3. Audio Sense – The amplifier will automatically turn on when the amplifier’s main input receives an audio signal. At the moment that either the left or right input jacks receive a signal, the amplifier will automatically turn on. Once the signal stops, the amplifier automatically goes into stand-by mode after 3 minutes.

BRIDGE MODE

To bridge two adjoining channels move the switch marked “BRIDGE” to the “ON” position. The output of the combined channels can then be used to power one speaker. Do not connect more than one speaker to the outputs of the bridged channel.

REMOTE POWER ON

3-24V DC/AC Trigger in – 3-24V AC or DC input to trigger power up with voltage from another device, such as a receiver. The voltage source must be connected to the trigger-input jack on the back of the amplifier.

12V DC Control Out – The 12V output jack on the back of the amplifier can be used to turn on a variety of components equipped to be activated when they receive a 12V DC output.
