TXi4408 / TXi6408 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 a Y-adapter 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

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.
