Crestron CNAMPX-16X60 16 Channel Professional Audio Amplifier
16 Channel Professional Audio
Amplifier: CNAMPX-16X60
Description
Functional Description
The CNAMPX-16X60 is a Crestron control network (Cresnet) 16 channel, 60-
Watts per channel audio amplifier. Typically installed in addition to the CNX-PAD8,
the unit provides remote system power on/off and remote zone on/off capabilities.
The CNAMPX-16X60 reports any electrical fault within itself or from a speaker
load. The voltage from each speaker terminal is monitored and ambient temperature
within the enclosure is reported via Cresnet and is available as Fahrenheit or Celsius.
These signals can be used to reduce the audio volume, activate an external cooling
fan, or turn the unit off under program control.
All audio connectors are gold plated to prevent corrosion and five types of wire
terminations can connect to the audio outputs. Highly efficient twin toroid
transformers provide ample power to eight two-channel amplifier modules. The eight
modules are of Crestron Detachable Modular Component (CDMC) design that
allows rapid field repair. Each channel (two per module) of each module has its own
power supply and filter capacitors that produce over 108,000 microFarads for
enhanced dynamic range. The heat sinks of each channel contain more than 300
square inches of radiating surface allowing cooler operation. No fans are required but
the unit must have a minimum of one rack space above and below for adequate
ventilation.
Physical Description
The CNAMPX-16X60, shown on the next page, is housed in a black enclosure with
silk-screened labels on the front and rear panels. The enclosure consists of 13-gauge
powder-coated steel with stainless steel screws. The front panel contains the main
power switch and light-emitting diode (LED). All audio input and output, Cresnet,
and power connections are made on the rear panel. There are four rubber feet on the
base of the unit for stability and to prevent slippage and two mounting ears with
screws are provided for rack mounting.

Setup
1 The latest software versions can be obtained from the Downloads | Software Updates section of the
Crestron website (www.crestron.com)
2 CNX update files are required for either CNMSX-AV/Pro or CNRACKX/-DP. Filenames for CNX
update files have a UPZ extension and are in one EXE or zipped UPZ file. To avoid program
problems, make certain you are using the update file with the correct suffix letter (e.g., V, W, X).
. Refer to the NOTE after the last footnote.
NOTE: Crestron software and any files on the website are for Authorized Crestron
dealers and Crestron Authorized Independent Programmers (CAIP) only. New users
may be required to register to obtain access to certain areas of the site (including the
FTP site).
As of the date of manufacture, the CNAMPX-16X60 has been tested and found to
comply with specifications for CE marking.
NOTE: This device complies with part 15 of the FCC rules. Operation is subject to
the following two conditions: (1) these devices may not cause harmful interference,
and (2) these devices must accept any interference received, including interference
that may cause undesired operation.
Network Wiring
When calculating the wire gauge for a particular Cresnet run, the length of the run
and the power factor of each network unit to be connected must be taken into
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
40,000
Where:
R <
L x PF
The required wire gauge should be chosen such that the resistance value is less than
the value calculated in the resistance equation. Refer to the table after this paragraph.
6 • 16 Channel Professional Audio Amplifier: CNAMPX-16X60 Operations Guide – DOC. 8155
R = Resistance (refer to table below).
L = Length of run (or chain) in feet.
PF = Power factor of entire run (or chain).

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.

Identity Code
Every equipment and user interface within the Cresnet network requires a unique
NET ID. These codes are recognized by a two-digit hexadecimal number from 03 to
FE. The NET ID of the unit must match an ID code specified in the SIMPL
Windows program. The NET ID of the CNAMPX-16X60 is factory set to 3D. The
NET IDs of multiple CNAMPX-16X60 must all be unique and changed from a PC
via SIMPL Windows or Crestron VisionTools
Pro-e (VT Pro-e).
The method for changing the unit’s NET ID is identical regardless of the software
chosen. Attach one of the CNAMPX-16X60s to the control system (verify that the
software is running) and complete the following steps to change the NET ID:
1. Disconnect all Cresnet devices from the control system, except for the
unit that needs to have its NET ID changed.
2. Select Tools | Viewport to open the “Crestron Viewport” window.
3. Select Functions | Set Network ID. The software checks the baud rate
and then opens the “Set Network ID” window.
4. In the “Set Network ID” window, highlight the unit.

Programming with SIMPL Windows
SIMPL (Symbol Intensive Master Programming Language) is an easy-to-use
programming language that is completely integrated and compatible with all
Crestron system hardware. The objects that are used in SIMPL are called symbols.
SIMPL Windows offers drag and drop functionality in a familiar Windows®
environment.
SIMPL Windows is Crestron's software for programming Crestron control systems.
It provides a well-designed graphical environment with a number of workspaces
(i.e., windows) in which a programmer can select, configure, program, test, and
monitor a Crestron control system.
The next three sections describe a CNAMPX-16X60 within a SIMPL Windows
program. The first section details the SIMPL symbol and the second section
describes how an example program works by using a textual description and a block
diagram.
NOTE: The following descriptions assume that the reader has knowledge of SIMPL
Windows. If not, refer to the extensive help information provided with the software.
NOTE: VT Pro-e is a Windows compatible software package for creating Crestron
touchpanel screen designs.
NOTE: VT Pro-e (version 2.1.8 or later) is required to produce the CNAMPX16X60 example touchpanel pages. The latest version of VT Pro-e can be obtained
from the Downloads | Software Updates section of the Crestron website
(www.crestron.com ). New users are required to register in order to obtain access to
the FTP site.
NOTE: There is no need to recreate the CNAMPX-16X60 example touchpanel
pages or example SIMPL Windows program. Both are available from the Crestron
FTP site (ftp://ftp.crestron /Examples). Search for CNAMPXEX.ZIP that contains
CNAMPX-EX.SMW, CNAMPX-EX.VTP and associated macros required to
complete the program.

Example Basic Touchpanel Pages
NOTE: VT Pro-e is required to produce the CNAMPX-16X60 example basic
touchpanel pages. The latest version of VT Pro-e can be obtained from the
Downloads | Software Updates section of the Crestron website (www.crestron.com).
New users are required to register in order to obtain access to the FTP site.
The example touchpanel page shown below is provided to demonstrate the basic
capabilities of the CNAMPX-16X60. After selecting a room to control, the desired
audio source is selected. Each source has a “Controls” subpage that is unique for the
particular type of device. As shown, the jukebox that is available as an audio source
can be programmed to skip to the next or previous track. Skipping to the next or
previous disk can also be programmed as an available function. The audio volume
can be increased, decreased or muted by the three buttons at the lower-left of the
page. Pressing the button in the upper-right corner of the display accesses the
CNAMPX-16X60 diagnostics page.

The diagnostic page shown below may be used to monitor outputs of the CNAMPX16X60. The status of the override button is displayed, the circuitry of the eight
amplifier modules is each monitored for electrical errors, and the output of each
module is monitored for wire faults. The ambient temperature within the CNAMPX16X60 enclosure may be displayed and the audio level (rooms 1 through 4 for this
example) can be monitored. Pressing the BACK button in the lower-left corner of the
display returns the display to the main page.

How the Example Program Works
The example SIMPL program for the CNAMPX-16X60 is shown on the next page as
a block diagram. The diagram shows only the components and logic associated with
example touchpanel. The actual program involves extensive CNX-PAD8 logic and
certain inputs and outputs have been rearranged or omitted for clarity.
In the block diagram, the signals labeled A through F are feedback to the touchpanel.
