ATA800.2 / ATA1200.2 / ATA2000.2 TWO CHANNEL AMPLIFIER APPLICATIONS
FULL RANGE STEREO
This is the most basic application for the 2 channel amplifiers.
1. Interconnect cable checklist:
Connect the
LINE INPUTS
to the Radio/CD with good quality RCAcables.
2. Crossover Switch:
The
X-OVER
switch must be in the
FULL
3. Crossover frequency control checklist:
N/Afor full range operation.

MONO
This application illustrates the basic mono bridging method for all Autotek
amplifiers.
Interconnect cable checklist:
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.
Important:
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 +.
