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
- 1 Ohm 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
- Refer to the section “Settings for Best Performance” channels on the amplifier. You sacrifice the ability to fade front to rear though.
Minimum final loudspeaker impedances: Interconnect cable checklist:
- 2 Ohms per channel for channels 1-4 Connect Stereo Left and Right RCA’s from headunit to CH1&2 RCA Inputs.
- 1 Ohm on channel 5
Switch setting checklist:
- CH 1 / 2 X-OVER: FULL
- CH 3 / 4 X-OVER: FULL
5-Channel Amplifiers
FEATURES:
- 3 Sets of RCA inputs
- LEVEL: Variable sensitivity from 0.2V to 6V
- BASS EQ: Adjustable 45Hz bass boost from 0dB to 10dB
- X-OVER: Selects internal crossover functions
- FULL: Bypasses all crossovers for full frequency operation
- BP: Selects the built in LOW PASS filter, variable from 30Hz to 150Hz
- HI: Selects the built in HI PASS filter, variable from 10Hz to 15KHz
- POWER LED: Indicates the powered up and turned on condition
- PROTECTION LED: Indicates a high voltage, low voltage, short circuit,
hard clip, over heating or DC fault condition.
- MODE: “2” indicates one set of RCA’s are being used. This will also pass signal to channels 3/4 and 5 through
1/2 inputs. “4” indicates connecting 2 sets of RCA’s to 1/2 and 3/4 inputs. “5” indicates connecting 3 sets of
RCA’s to channels 1/2, 3/4 and mono signal to channel 5 inputs.
