2 Channel Professional Audio Amplifier

2 Channel Professional Audio
Amplifier: CNAMPX-2X60

Description

Functional Description

The CNAMPX-2X60 is a 2-channel, 60-Watts per channel audio amplifier. As part
of a Cresnet system, the unit can accept remote power on/off commands and report
ambient temperature within the enclosure. Temperature is available as Fahrenheit or
Celsius and the signal can be used under program control to reduce the audio
volume, activate an external cooling fan, or turn the unit off.

Functional Summary

• 2 Channels of Amplification

− 60 Watts/Channel Stereo into 8 Ohm Load (90

Watts into 4 Ohms)

− 200 Watts Bridged into 8 Ohms

− Flat within +0, -0.1 dB from 20 Hz to 20 KHz

• 3-Position Mode Selection Switch: Stereo, Mono

(Sum L+R), and Bridged

• Can Be Used In Many Applications, Including:

− Local Stereo Amp For Remote Room

− Sub-Amp For Home Theater’s Passive Subwoofer

All audio connectors are gold plated to minimize oxidation, and three types of wire
terminations can connect to the audio outputs. A highly efficient toroid transformer
provides ample power to the two-channel amplifier module. No fans are required but
if the unit is placed in a rack configuration, it must have a minimum of one rack
space above and below for adequate ventilation.

The CNAMPX-2X60 is also available as an international version. All of the features
are identical with the exceptions of the international AC power requirements and
power cord and the unit nomenclature of CNAMPXI-2X60. Throughout this
operations guide, all references to CNAMPX-2X60 apply to both versions except
where noted.

Physical Description

The CNAMPX-2X60, shown below, is housed in a black enclosure with labeling on
the front and rear panels. The enclosure consists of 13-gauge powder-coated steel

consideration. If Cresnet units are to be daisy-chained on the run, the power factor of
each unit to be daisy-chained must be added together to determine the power factor
of the entire chain. If the unit is a home-run from a Crestron system power supply
network port, the power factor of that unit is the power factor of the entire run. The
length of the run in feet and the power factor of the run should be used in the
following resistance equation to calculate the value on the right side of the equation.

Resistance Equation

NOTE: All Cresnet wiring must consist of two twisted-pairs. One twisted pair is the
+24V conductor and the GND conductor and the other twisted pair is the Y
conductor and the Z conductor.

NOTE: When daisy-chaining Cresnet units, strip the ends of the wires carefully to
avoid nicking the conductors. Twist together the ends of the wires that share a pin on
the network connector, and tin the twisted connection. Apply solder only to the ends
of the twisted wires. Avoid tinning too far up the wires or the end becomes brittle.
Insert the tinned connection into the Cresnet connector and tighten the retaining
screw. Repeat the procedure for the other three conductors.

removal and can be performed with the unit installed in an equipment rack.

CAUTION: Refer to the table below. Use only the listed fuse for each
corresponding CNAMPX model and version to replace a defective fuse. The fuse is
available commercially but if a replacement fuse cannot be obtained, contact
Crestron customer service.

The fuse holder of non-international versions contains a spare fuse. Verify that the spare

fuse is the same type, size and rating as the defective and use as the replacement. If the
spare fuse is used as the replacement, obtain the same type, size and rating fuse to be
used as the spare as soon as possible.
