ONX4.80/500

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.

5 Channel Discrete Operation:

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.

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.

Switch setting checklist:

-CH 1 / 2 X-OVER: FULL

-CH 3 / 4 X-OVER: FULL

MODE: “5” since 3 sets of RCA’s are connected.

Control checklist:

-Refer to the section “Settings for Best Performance”

Minimum final loudspeaker impedances:

-2 Ohms per channel for channels 1-4

-1 Ohm on channel 5

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. You sacrifice the ability to fade front to rear though.

Interconnect cable checklist:

Connect Stereo Left and Right RCA’s from headunit to CH1&2 RCA Inputs.

MODE: “2” since 1 set of RCA’s are connected.
