AT1000 / AT1500 / 2 CHANNEL AMPLIFIER APPLICATIONS
3
FULL RANGE MONO
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 X-OVER switch must be in the FULL position.
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:
4 &-2-Ohms stereo mode or 4-Ohms mono mode
This amplifier will not do 1-Ohm stereo or 2/1-Ohm mono operation.
This application illustrates the basic mono bridging method for all Autotek 2

Important:
If you are using the mono sub bass output of an active crossover, there is
