5 channel discrete, one being mono low pass
You can use this configuration simply as 4 discrete full range channels, with a 5th
low pass channel. All of the crossovers are bypassed , except the LOW PASS on
channel 5. The 5 channels can also be utilized with an outboard active crossover,
or with crossovers in head units or equalizers. This setup is common when your
headunit or crossover has 2 sets of full range RCA outputs and 1 set of mono
subwoofer outputs.
Interconnect cable checklist:
Connect channel 1&2 inputs to the front output, channels 3&4 to the rear output,
and channel 5 to the mono subwoofer output of a head unit or in dash equalizer.
The LOW PASS filter on channel 5 will be in tandem with that of the source. You
can either set it to the same frequency for a steeper rolloff, or set it to a higher
frequency to minimize it's effect. By the same reasoning, you could switch
channels 1,2,3&4 high pass crossovers in for steeper high pass slopes.
Switch setting checklist:
INPUT MODE: 5CH DISCRETE
- CH 1 / 2 X-OVER: FULL
Single Set of Stereo RCA's
We will use the same basic setup on the speaker and subwoofer connections as
above to illustrate an installation that only has 1 set of stereo RCA's to connect to
this amplifier. By switching the amplifier to 2CH on the INPUT MODE, you now
provide signal to all channels on the amplifier.
Interconnect cable checklist:
Connect Stereo Left and Right RCA's from headunit to CH1&2 RCA Inputs.
Switch setting checklist:
INPUT MODE: 2CH
- CH 1 / 2 X-OVER: FULL
- CH 3 / 4 X-OVER: FULL
- CH 3 / 4 X-OVER: FULL
Crossover frequency control checklist:
- CH 1 / 2 HIGH PASS: N/A
- CH 3 / 4 HIGH PASS: N/A
- CH 3 / 4 LOW PASS: N/A
- CH 5 LOW PASS: 80 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"
