3 Setup

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.com.

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.

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.
