Installation - Crown CE 4000 Reference Manual

2 Installation

Follow these instructions for a detailed explanation of CE 4000
installation procedures and options. If you just want to get up and
running as quickly as possible, see the Quick Start section on
page 6.
2.1—Begin with the amplifier turned off and disconnected
from the power receptacle. The CE4000 power switch is
located on the left side of the front panel; it is off ("O") when
depressed on the left. Equipment that will be connected to
the inputs of the amplifier (such as mixers,equalizers or signal
processors) should also be turned off.
2.2—Mount the amplifier. Your CE 4000 amp can be mounted in
a standard, 19-inch (48.3-cm) equipment rack, or it can be
simply stacked with other equipment. The CE 4000 amp is
provided with a convenient 3-foot (1-meter) power cord to
minimize excess cordage when installed in a rack. Do not
use extension cords. Properly wired power outlets must be
provided close to the mounted amplifier.
If you choose to mount your amp in a rack, you should secure
the back of the rack as well as the front. Securing the amp at
both front and rear will assure that the amp stays in place,
even when the rack is transported or accidentally dropped
(which we know never happens).

2.3—Set the mode switch. Make sure your amplifier is turned
off ("O") before moving this switch. The Mode switch
should be in the "Stereo" position when you're running in
Stereo Mode. Stereo Mode allows independent inputs on
the left and right channels to feed separate speakers at
the output. It's the configuration typically chosen for ev-
eryday audio applications.
Turn the Mode switch to "Bridge-Mono" to have a single
input that feeds to a single output with twice the voltage
of Stereo Mode. Use this configuration if you want to give up
stereo capabilities in order to drive your speakers louder.
Note that the wiring will also need to be adjusted for this
configuration—that includes both input and output wir-
ing. See Step 2.5 (Connecting the Outputs) and Figure 4.8
later in this section for correct wiring when running in
Bridge-Mono mode.
2.4—Connect the inputs of the CE 4000 amp to your mixer,
equalizers, or signal processors ahead of the amp. Three
types of balanced input connectors are provided, allow-
ing you to choose barrier strip,
or 3-pin XLR connectors.* You can also choose to use ei-
ther balanced or unbalanced wiring. (See the information
on "Balancing the Line" in the Crown Pro Information
Guide section for an explanation of balanced vs. unbal-
anced wiring.)
If the Mode switch is in "Bridge-Mono" position, only
the Channel 1 input connectors should be used.
*Optional SST crossover may provide other input connector options.
