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 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.

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 X-OVERswitch must be in the FULL position.

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 roll-off.

Minimum final loudspeaker impedance:

- 4-Ohms mono.
