MAXP4260N 4 CHANNEL AMPLIFIER APPLICATIONS
2 way active. or bl-ampllfled 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 negative terminal
to
LEFT -.
Switch setting checklist:
-1j2CHX-OVER: HP
- 3/4CH X-OVER: LP
Crossover frequency control checklist:
channels 1j2
-HIGH PASS: 100 Hz
-LOW PASS: NJA
Channels 3/4:
- HIGH PASS ,subsonic!: 20 Hz
- Low PASS: 100 Hz
Please note that these frequency points only. Refer
to
the
loudspeaker manufacturer specifications and the section
"setting up system after installation for best performance"
2 way active. or bi-amplified system with mono bass.
and faded highsj 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 I anf 2 will be used for
h
ighs. 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 to the section "setting up systems after in stall ation for best performance"
Minmum 'inalloudspeaker impedances:
- 2 ohm per channel in stero mode
- 4 ohm mono bridged.
