Hardware Setup And Configuration - Crown DCi 8 Operation Manual

Hardware Setup and Configuration

Wire Input Connectors
Crown recommends using pre-built or professionally wired balanced cables (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.
AVB Connectors
For AVB audio connection, standard Category 6 cabling can be used.
When using the AVB Primary and Secondary input connections, pass the CAT 6 cable twice
through a Ferrite core located as close to the amplifier as possible. This is to ensure compliance
with emissions regulations. See Figure 5.
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.
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.
