MB QUART ONYX ONX1.1000D, Installation Manual

ONX4.80/500

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

: 

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.
