Wiring 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.
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 odd-numbered input channels (1,3,5,7) should be wired for each bridged pair.
For Dante audio connections, standard Category 5e or 6 Ethernet cabling should be used for Gigabit networks. Category 5 cabling can be used for 100Mbps network
connections. Primary and Secondary Dante ports are provided; Dante audio traffic is duplicated to both of these ports. The Secondary port can be connected to a second
network switch for redundant operation in the event the Primary cable connection or switch is compromised.

Wiring Output Connectors
IMPORTANT:
The amplifier output mode (Low Z, High Z) should be properly configured for the application before connecting the speakers. By default, all outputs are
configured for Low Z operation. See
"Hi-Z/Low-Z" on page 15
for more information.
Before making any output connections, ensure the power cord is disconnected from the amplifier and carefully review the total impedance for loudspeakers connected to
each amplifier output. If multiple loudspeakers are connected to an output in Low Z mode (i.e., in series, parallel, or series-parallel), be certain the total system impedance
is within allowed specification for the output. When multiple loudspeakers are connected to one output in High Z mode, be certain total tapped power is below the rated
power output for the channel. See
"DCi DA Specifications" on page 47
for supported load specifications.
NOTE:
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 5
). For best results, Crown recommends Panduit part #PV10-6LF-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.
For application-specific output connection diagrams, including how to wire outputs for bridge mono operation, see
