ZXi4408 / ZXi6408 / ZXi8408 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 Zeus 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: HI
- 3/4CH X-OVER: LP/BP
Crossover frequency control checklist:
Channels 1/2:
- HI PASS: 100 Hz
- LOW PASS: N/A
LEFT TO CHANNELS 1 AND 3

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.
