3.6  Wire Your System

3.6.1 Stereo Mode

Typical input and output wiring is shown in 
Figure 3.6.  Turn off the amplifier, and set the 
Stereo/Mono mode switch on the back to Stereo.

INPUTS: Connect input wiring for both channels.

OUTPUTS: Maintain proper polarity (+/-) on out-
put connectors.

Connect Channel 1 positive (+) speaker load  to 
Channel 1 positive terminal of amp; repeat for 
negative (-). Repeat Channel 2 wiring as for 
Channel 1. 

3.6.2 Bridge-Mono Mode

Typical input and output wiring is shown in 
Figure 3.6.  Turn off the amplifier, and set the 
Stereo/Mono mode switch on the back to Bridge 
Mono.

INPUTS: Connect input wiring to Channel 1 
only.

OUTPUTS: Connect the speaker across the posi-
tive (red) terminals of each channel. Do not use 
the negative terminals when the amp is being 
operated in Bridge-Mono mode. The load must 
be balanced so neither lead is connected to 
ground.

CAUTION: Connect only balanced equip-
ment (meters, switches, etc.) to the 
Bridge-Mono output. Both sides of the 
line must be isolated from the input 
grounds or oscillations may occur.

NOTE: To prevent distortion and low lev-
els, the Channel 2 level control should be 
set fully counter-clockwise when operat-
ing the amplifier in Bridge-Mono mode.

NOTE: Crown provides a reference of wiring pin 
assignments for commonly used connector 
types in the Crown Amplifier Application Guide 
(Section 1.21.) available at www.crownaudio.

3 Setup

3.6.3  Parallel-Mono Mode

Typical input and output wiring is shown in
Figure 3.6. Turn off the amplifier, and set the Ste-
reo/Mono mode switch on the back to Parallel 
Mono.  Turn down the Channel 2 level control.

INPUTS: Connect input wiring to Channel 1 
only.

OUTPUTS: Connect positive (+) speaker load to 
amplifier Channel 1 red (+) binding post.  Con-
nect negative (-) speaker load to amplifier Chan-
nel 1 black (-) binding post.  Add a 14 gauge (or 
larger) jumper wire between the red (+) binding 
posts of both channels 1 and 2.

CAUTION: When the amplifier is wired for 
Parallel-Mono mode, do not change the 
rear switch to Stereo or Bridge-Mono.  
Doing that will result in inefficient opera-
tion, high distortion and excessive heat-
ing.
