PZi100.4 / PZi125.4 / PZi175.4 / 4 CHANNEL AMPLIFIER APPLICATIONS

2 way active, or bi-amplified system with mono bass

This application shows how easily a 2 way active system can be implemented using a 4 channel amplifier. Channels 1 and 2 will be used for highs, and channels 3 and 4 for mono bass.

Interconnect cable checklist:

- We need to feed the same signal to both sets of channels, so must use 2 Y- adapters, one to feed the LEFT signal to channels 1 and 3, and the right signal to channels 2 and 4, as shown.

Mono bass woofer wiring:

-Connect the mono speaker positive terminal to the LEFT +, and its negative terminal to RIGHT -.

Switch setting checklist:

-1/2CH X-OVER: HP

-3/4CH X-OVER: LP

Crossover frequency control checklist:

Channels 1/2:

-HI PASS: 100 Hz

-LOW PASS: N/A

Channels 3/4:

-HI PASS (subsonic): 20 Hz

-LOW PASS: 100 Hz

Please note that these frequency points are suggestions only. Refer to the loudspeaker manufacturer specifications and the section “Setting up systems after installation for best performance”

Level control checklist:

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

Minimum final loudspeaker impedances:

-2-Ohms per channel in stereo mode.

-4-Ohms mono bridged.

2 way active, or bi-amplified system with mono bass, and faded highs/lows

Here we present a variation of the previous system. Since this is a 2 way system, we can use the front outputs from a head unit to drive the highs, and the rear output to drive the bass This method allows the listener to easily adjust the relative levels of bass to highs, with the front to rear fade on the head unit.

Channels 1 and 2 will be used for highs, and channels 3 and 4 for mono bass.

Interconnect cable checklist:

-Use good quality RCA leads to connect the inputs of the amplifier to the source as shown.

-Follow the instructions as per the previous system for switch and crossover settings.
