Setup
7 Channel Surround-Sound Amplifier
WARNING: To prevent bodily injury when mounting or servicing this unit in a rack, you must take special precautions to ensure that the system remains stable. The following guidelines are provided to ensure your safety.
If the rack is provided with stabilizing devices, install the stabilizers before mounting or servicing the unit in the rack.
When mounting this unit assembly in a partially filled rack, load the rack from the bottom to the top with the heaviest component at the bottom of the rack.
CAUTION: Due to the heat dissipation of the CNAMPX7X200 (and all audio amplifiers in general), allow at least one free rack space above and below the
CNAMPX7X200 for proper circulation.
NOTE: Reliable grounding of rack-mounted equipment should be maintained.
Particular attention should be given to supply connections other than direct connections to the branch circuit. (e.g., use of power strips).
Rack Mounting
Two “ears” are provided with the unit and must be installed so that it can be rack mounted. Refer to the following illustration and complete the procedures below to attach ears to the unit. The only tool required is an Allen wrench (supplied).
Ear Attachment for Rack Mounting

7 Channel Surround-Sound Amplifier Crestron
1. Using the supplied Allen wrench, remove and retain the three side screws closest to the front panel.
2. Position a rack ear so that its mounting holes align with the vacated holes, and secure the ear to the unit with the three screws from step 1.
3. Repeat the procedure to attach the remaining ear to the opposite side.
Network Wiring
NOTE: When installing network wiring, refer to the latest revision of the wiring diagram(s) appropriate for your specific system configuration, available from the
Downloads | Product Manuals | Software and Wiring Diagrams section of the
Crestron website (www.crestron.com).
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
R < L x PF Where: R = Resistance (refer to table below).
L = Length of run (or chain) in feet.
PF = Power factor of entire run (or chain).
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 below.

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 plug and tighten the retaining screw. Repeat the procedure for the other three conductors.

Programming
The easiest method of programming, but does not offer as much flexibility as
SIMPL Windows.
You can create a program that allows you to control the CNAMPX-7X200 through a
Crestron control system using the Crestron programming tools Crestron Application
Builder™ (AppBuilder) and SIMPL™ Windows ® . These tools are intended for users with different levels of programming knowledge. The flexibility of each tool is proportional to the degree of programming expertise (i.e., the more flexible, the more a programmer needs to know and account for). Of course, one can initiate programming using the easiest method (Crestron AppBuilder) and use advanced techniques that are available from SIMPL Windows to customize the job.
The following are recommended software version requirements for the PC:
• SIMPL Windows version 2.01.05 or later. Requires SIMPL+ Cross
Compiler version 1.1.
• Crestron Database version 15.6.8 or later.
• Application Builder version 1.0.9 or later. Requires SIMPL Windows.
Programming with the Crestron AppBuilder
The Crestron AppBuilder offers automatic programming for such residential and commercial applications as audio distribution, home theater, video conferencing, and lighting. The interface of this tool guides you through a few basic steps for designating rooms and specifying the control system, touchpanels, devices, and functionality. The Crestron AppBuilder then programs the system, including all touchpanel projects and control system logic.
The Crestron AppBuilder is fully integrated with Crestron's suite of software development tools, including SIMPL Windows, VT Pro-e, Crestron Database, User
IR Database, and User Modules Directory. The Crestron AppBuilder accesses these tools behind the scenes, enabling you to easily create robust systems.
Programming with SIMPL Windows
NOTE: The following assumes that the reader has knowledge of SIMPL Windows.
If not, refer to the extensive help information provided with the software.
NOTE: In the following, the PRO2 control system is used.
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. SIMPL Windows offers drag and drop functionality in a familiar Windows
environment.
This section explains how to create a SIMPL Windows program that includes the
CNAMPX-7X200.
Configuration Manager is where programmers “build” a Crestron control system by selecting hardware from the Device Library. In Configuration Manager, drag the
PRO2 from the Control Systems folder of the Device Library and drop it in the upper pane of the System Views. The PRO2 with its associated communication ports is displayed in the System Views upper pane.
Operations Guide – DOC. 8179 7 Channel Surround-Sound Amplifier: CNAMPX-7X200 • 9
