Crown recommends using pre-built or professionally wired balanced line (two- conductor plus shield). Balanced wiring provides better rejection of unwanted noise and hum but unbalanced line may also be used. For more information, refer to the Crown Amplifier Application Guide, available online at www. crownaudio.com.

Use 3-pin Phoenix-type cable ends at the amp input connectors.

Figure 4.4.1 shows connector pin assignments for balanced wiring and figure 4.4.2 shows connector pin assignments for unbalanced wiring.

NOTE: Custom wiring should only be performed by qualified personnel. Class 2 wiring is required.

Crown recommends using professionally constructed, high quality, two-conductor, heavy gauge speaker wire and connectors. Use 2-pin Phoenix-type connectors (Included with the amp).

Suggested below are guidelines to select the appropriate size of wire based on the distance from amplifier to speaker. Check with local code as this may vary.
