WARNING: Before you start to set up your amplifier, read and observe the Important
Safety Instructions found at the beginning of this manual.
Install the Amplifier
CAUTION: Before you begin, make sure your amplifier is disconnected from the
power source and that all level controls (see Page 14) are set to INF.
All DCi Series amplifiers are 3.5 in. (8.9 cm).high and 19 in. (48.3 cm) wide. All are 14.25
in. (36.2 cm) deep except the DCi8|600 and 4|1250 which is 17 in. (43.2 cm) deep.
(See Figure 1)
Mount the unit in a standard 19-inch (48.3 cm) equipment rack (EIA RS-310B). You can
also place a single amp on a solid, stable surface or stack multiple amps.
NOTE: Amplifiers should be supported at both the front and rear of the rack.
Ensure Proper Cooling
When using an equipment rack, mount units directly on top of each other. Close any open
spaces in the rack with blank panels. (Open spaces will reduce cooling efficiency.) DO NOT
block front or rear air vents.
The rack should be a minimum of two inches (5.1 cm) away from the amplifier, and the back of
the rack should be a minimum of four inches (10.2 cm) from the amplifier back panel.

Set-up and System Conguration
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 oddnumbered 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.
Figure 3
Figure 4
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.
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.
Figure 5
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.

Set-up and System Conguration
Connect Loudspeakers and Configure for Loudspeaker Load
Determine load impedances and power requirements
Before making any connections, carefully check and review the total impedance for loudspeaker systems to be connected to each amplifier output. If multiple loudspeakers
are connected to one output (in series, parallel or series-parallel) for Lo-Z operation, be certain the total system impedance is within allowed specification for the output.
When multiple loudspeakers are connected to one output for Hi-Z operation, be certain total tapped power is below the rated power output for the channel. For additional
information, please consult Crown’s Amplifier Application Guide (available online at www. crownaudio.com).
Note: Illustrations and some text references are for channel pair 1 - 2 only. Connections and settings are identical for channels 3 – 4 on
four-channel models and for channels 5 – 6 and 7 – 8 on eight-channel models. Each channel pair may be configured independently on
multichannel models.
Dual Mode Low-Z (8, 4 or 2 Ohm)
Typical input and output wiring, along with Attenuator and Mode DIP Switch settings are shown in Figure 6. Make sure DIP
Switches are in the default OFF (down) position.
INPUTS: Connect the input with wiring in place for each channel. If the same signal is to drive both outputs of a channel pair (“mono”), the signal
must be split externally and applied to both inputs.
OUTPUTS: Maintain proper polarity (+/–) on output connectors. Connect the Channel 1 speaker’s positive (+) lead to amplifier Channel 1 positive terminal;
repeat for negative (–). Repeat Channel 2 wiring as for Channel 1, and for any subsequent channel pairs on multichannel models. Refer to Page 7
for output connector terminal assignments.
