P1-600.4 / P1-1000.4 4-CHANNEL AMPLIFIER APPLICATIONS

4 CHANNEL FULL RANGE SYSTEM

Here we show how to use the 4 channel amplifiers as straight forward discrete 4 channel full range units. The MODE switch should be in 4CH.

Interconnect cable checklist:

- Connect the four inputs of the amplifier to a Radio/CD with quality RCA cables.

Switch setting checklist:

-1/2CH X-OVER: FULL

-3/4CH X-OVER: FULL

Crossover frequency control checklist:

2 or 3 CHANNEL SYSTEM

Here we show how to use the 4 channel amplifiers as a 3 channel unit by taking advantage of the mono bridging capability of all Crunch 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:

-MODE: Set at 3CH

-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. If you only have 1 set of RCA outputs from your headunit, you can simply connect those to the inputs for ch 1/2 and switch the MODE to 2ch. The amplifier will auto sum the signal and provide mono output for bridged channels 3/4.

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 CH4 +, and its negative

terminal to CH3 - as shown.

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”

Minimum final loudspeaker impedances:

-2 ohm per channel in stereo mode.

-4 ohm mono bridged.
