Micro-Tech Series Power Amplifiers
Operation Manual
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

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.
