MAXP4260 4 CHANNEL AMPLIFIER APPLICATIONS
2 way active, or b .... mpllfted system with mono bass
This application shows how easily a 2
way
active system can be
implemented using a MAX PRO series 4 channel amplifier. Channels
I 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
I and 3, and the right signal to channels 2and 4, as shown.
Mono bass woofer wiring
- Connect the mono speaker positive terminal to the RIGHT +,
and
its
negaitive terminal to LEFT -.
Switch setting checklist:
• 1/2CH
X-oVER: HP
• 3/4CH
X-oVER: lP

2 way active, or bl-ampllfted system with mono bass,
and faded highsj 10_
Here
we
present a variation of the previous system. Since
this is a 2 way system, wecan 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 anf 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.
Level control checklist:
Refer

the section
"setting
up systems after in stall ation for best performance"
