2 or 3 CHANNEL FULL RANGE SYSTEM

Here we show how to use the 4 channel amplifiers as full range 2 or 3 channel units by taking advantage of the mono bridging capability of all Autotek amplifiers.

The following example shows how to create a 3 channel system by mono bridging channel pair 3 / 4. In order to create a 2 channel system, simply follow the example to also mono bridge channel pair 1 / 2.

Interconnect cable checklist:

- Connect the inputs of channel pair 1/2 to a suitable stereo source, e.g. a head unit

with good quality RCA cables.

- A MONO signal source is required to bridge channel pair 3/4, such as would be

available from the mono sub bass output of an active crossover, whether

standalone, 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.

Crossover frequency control checklist:

Channels 1/2:

-HI PASS: N/A

-LOW PASS: N/A

Channels 3/4:

-HI PASS: N/A

-LOW PASS: N/A

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 rolloff.

Level control checklist:

-Refer to the section “Setting up systems after installation for best performance”

- 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 - as shown.

Minimum final loudspeaker impedances:
