AT1000 / AT1500 / 2 CHANNEL AMPLIFIER APPLICATIONS
FULL RANGE STEREO
This is the most basic application for the SUPER SPORT Series 2 channel amplifiers.
1. Interconnect cable checklist:
Connect the LINE INPUTS to the Radio/CD with good quality RCA cables.
2. Crossover Switch:
The
3.Crossover frequency control checklist: N/A for full range operation.
4.Line Level:
Refer to the section “Setting up systems after installation for best performance”.
NOTE: Minimum final loudspeaker impedances:

FULL RANGE MONO
This application illustrates the basic mono bridging method for all Autotek 2 channel 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 LEFT +, and its negative terminal to RIGHT
Switch setting checklist:
- The AMPLIFIER
Crossover frequency control setting checklist:
N/A for full range operation.
TIP: If you are using the mono sub bass output of an active crossover, there is nothing wrong with switching in the low pass filter in these amplifiers for a steeper low pass
Minimum final loudspeaker impedance:
- 4-Ohms mono.
