ATA800.2 / ATA1200.2 / ATA2000.2 TWO CHANNEL AMPLIFIER APPLICATIONS
This is the most basic application for the 2 channel amplifiers.
Connect the
to the Radio/CD with good quality RCAcables.
The
switch must be in the
position.
N/Afor full range operation.

FULL RANGE STEREO
MONO
This application illustrates the basic mono bridging method for all Autotek
amplifiers.
A MONO signal source is required, such as would be available from the mono
sub bass output of an active crossover, whether stand alone, or built into a head
unit or equalizer.
Do not be tempted to connect the hot, or positive
outputs, from any source together to obtain a mono signal, as this could very well
damage the output stage of that source.
It is necessary to feed the SAME signal to both left and right inputs via a Y-adapter
RCA cable. Connect the mono speaker positive terminal to the RIGHT -, and its
negative terminal to LEFT +.
- The
switch should be in the
position and the
should be in the
position.

The
inputs are used when the radio/CD player does not have RCA cable outputs. You can connect the radio/CD player speaker wires directly to the
amplifier via the high Level Inputs.
