CE2000TX Power Amplifier

3.1 Unpack Your Amplifier

Please unpack and inspect your amplifier for
any damage that may have occurred during
transit. If damage is found, notify the transpor­tation company immediately. Only you can ini­tiate a claim for shipping damage. Crown will
be happy to help as needed. Save the shipping
carton as evidence of damage for the shipper’s
inspection.

We also recommend that you save all packing
materials so you will have them if you ever
need to transport the unit. Never ship the

unit without the factory pack.

YOU WILL NEED (not supplied):

• Input wiring cables

• Output wiring cables
Rack for mounting amplifier (or a stable surface

for stacking)

WARNING: Before you start to set up
your amplifier, make sure you read and
observe the Important Safety Instruc­tions found at the beginning of this
manual.

3.2 Install Your Amplifier

CAUTION: Before you begin, make sure
your amplifier is disconnected from the
power source, with power switch in the
“off” position and all level controls
turned completely down (counterclock­wise).

Use a standard 19-inch (48.3 cm) equipment
rack. See Figure 3.1 for amplifier dimensions.

You may also stack amps without using a
cabinet.

NOTE: When transporting, amplifiers should be
supported at both front and back.

3.3 Ensure Proper Cooling

When using an equipment rack, mount units
directly on top of each other. Close any open
spaces in rack with blank panels. DO NOT
block front or rear air vents. The side walls of
the rack should be a minimum of two inches
(5.1 cm) away from the amplifier sides, and the
back of the rack should be a minimum of 4
inches (10.2 cm) from the amplifier back panel.

3.4 Choose Input Wire
and Connectors

You have three choices of input connectors:
1/4-inch (6.35-mm) phone, 3-pin XLR, or
barrier strip. You can also use either balanced or
unbalanced wiring.

Figure 3.3 shows balanced connector pin
assignments for XLR and phone. Figure 3.4
shows unbalanced connector pin assignments
for XLR and phone.

Figure 3.5 shows barrier strip input wiring for a
balanced signal. Both channels should be wired
using a common center terminal for ground con­nection.

NOTE: Custom wiring should only be
performed by qualified personnel.

3 Setup

3.5 Choose Output Wire and Con­nectors

Crown recommends using pre-built or profes­sionally wired, high-quality, two- or four-con­ductor, heavy gauge speaker wires. They should
be terminated with Neutrik Speakon NL4FC con­nectors (Figure 3.6) at one end and appropriate
connectors to fit your speakers at the other end.

If your CE 2000TX amplifier came equipped with
the CEAS1 (barrier strip) or CEAS2 (5-way bind­ing post) optional output connectors, you may
wire your output to these connectors instead.
Optional output connectors can also be ordered
as a Service Option for installation on existing
CD 2000TX amplifiers.

If the CEAS1 Output Module is installed, use ter­minal forks or bare wire for your output connec­tors (see Figure 3.7).

To prevent the possibility of short-cir­cuits, replace the cover on the barrier
strip after completing the output wiring.

If the CEAS2 Output Module is installed, connect
to it with bare wires, spade lugs or banana plugs
on the speaker cables (Figure 3.8).

Using the guidelines below, select the appropri­ate size of wire based on the distance from
amplifier to speaker.

Distance Wire Size

up to 25 ft. 16 gauge

26-40 ft. 14 gauge
41-60 ft. 12 gauge

61-100 ft. 10 gauge
101-150 ft. 8 gauge
151-250 ft. 6 gauge

3.6 Wire Your System

3.6.1 Stereo Mode

Make sure the amplifier is turned off and the
level controls are turned down before you wire
the system.

Typical input and output wiring is shown in
Figure 3.9.

INPUTS: Connect input wiring for each channel.
OUTPUTS: Maintain proper polarity (+/-) on out-

put connectors.
Connect Channel 1 positive (+) speaker load to

Channel 1 positive terminal of amp; repeat for
negative (-). Repeat each channel wiring as for
Channel 1. Refer to Section 3.5 for output con­nector pin assignments. Make sure the Mode
switch is set to the “Stereo” position when oper­ating in Stereo mode.

How to Parallel the Inputs in Stereo Mode

There are three ways to feed the same signal to
each amplifier channel:

1. Buy a "Y" cable. Plug the female end into your
signal cable, and plug the split male ends into
both amplifier inputs.

2. Feed your signal to the Channel-1 input
(either barrier-block or Combo). Connect a
jumper wire (Figure 3.10) between the barrier­block Channel-1 (+) screw terminal and the
Channel-2 (+) screw terminal. Connect another
jumper wire between the Channel-1 (–) screw
terminal and the Channel-2 (–) screw terminal.

3. Feed your signal to the Channel-1 input screw
terminals. Using a mic cable or phone-to-phone
cable, connect Channel-1 Combo jack to Chan­nel-2 Combo jack.

See the next page for Bridge-Mono wiring.
