Operation Manual
Wire Input Connectors
Crown recommends using pre-built or professionally wired balanced line (two-conductor plus shield).
Balanced wiring provides better rejection of unwanted noise and hum; however, unbalanced line may
also be used. For more information, refer to the Crown Amplifier Application Guide, available online at
www.crownaudio.com.
Use 6-pin plug-in cable ends at the amp input connectors. A male connector is supplied for each input
of your model of amplifier. Additional connectors are available from Crown (P/N 5024623).
Figure 3 shows connector pin assignments for balanced wiring and Figure 4 shows connector pin
assignments for unbalanced wiring. Note that for bridged operation, only the connectors for odd-
numbered channels (1,3,5,7) for each bridged pair need be wired. See Page 9 and 11.
Wire Output Connectors
Crown has designed an output cover that does not need to be removed
to connect the output wiring.
Crown recommends using the included spade connectors and two- or
four-conductor, heavy gauge speaker wire. You may use terminal forks
up to 10 AWG or bare wire for your output connectors (see Figure 6).
For best results, Crown recommends Panduit part #PV10-10LF-L or
equivalent terminal fork. For bare wire, it is highly recommended that
output wiring is tinned. To reduce strain on input and output wiring,
Crown recommends the use of horizontal lacer bars. For best results,
Crown recommends Middle Atlantic part# LBP-4R90 or equivalent
horizontal lacer bar.
To prevent the possibility of short-circuits, wrap or otherwise insulate
exposed loudspeaker cable connectors.
For low-impedance loads, select the appropriate size of wire based on
the distance from amplifier to speaker.
Distance Wire Size
Up to 25 ft. (7.6m) 16 AWG
26-40 ft. (7.9-12.2m) 14 AWG
41-60 ft. (12.5-18.3m) 12 AWG
> 60 ft (18.3m) 10 AWG
CAUTION: Never use shielded cable for output wiring.
CAUTION: Never connect the speaker return to the chassis of the amplifier, or damage to the amplifier may result.
NOTE: Custom wiring should only be performed by qualified personnel. Class 2 output wiring is required.
