5 Channel Discrete Operation:
MODE: “5” since 3 sets of RCA’s are connected.
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.
Control checklist:
- Refer to the section “Settings for Best Performance”
Interconnect cable checklist:
Connect channel 1&2 inputs to the front output, channels 3&4 to the rear output, and
Minimum final loudspeaker impedances:
channel 5 to the mono subwoofer output of a head unit or in dash equalizer.
- 2 Ohms per channel for channels 1-4
- 2 Ohms on channel 5
Switch setting checklist:
- CH 1 / 2 X-OVER: FULL
- CH 3 / 4 X-OVER: FULL
Single Set of Stereo RCA’s
MODE: “2” since 1 set of RCA’s are connected.
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.
Control checklist:
By switching the amplifier to 2CH on the INPUT MODE, you now provide signal to all
