C2N-DAP8RC
Quick
Digital Audio Processor
With Room Control
Start
These instructions can be performed in the office or at the job site to get your Crestron® C2N-DAP8RC
Digital Audio Processor (DAP8RC) ready for operation quickly. They cover basic procedures necessary to
verify that the unit functions properly, and include running the example program, which is downloadable
from the Crestron FTP website.
Hardware Hookup
Before starting the hardware hookup procedures, make certain power to all devices is off.
NOTE: The DAP8RC is designed to be used only with a Crestron 2-Series control system.
NOTE: The DAP8RC requires 21 Watts of Cresnet power and may require a dedicated Crestron power
supply.
Connect Head End and Local Sources
Connect audio and video sources to the DAP8RC using the diagram below as a guide.

Connect Outputs
Connect audio and video outputs from the DAP8RC using the diagram below as a guide.
Network ID
The Net ID of the DAP8RC is factory set to 50. The Net IDs of multiple DAP8RCs in the same system must
be unique, and the Net ID of each unit must match an ID code specified in the SIMPL Windows program.
Refer to “Identity Code” on page 12 of the Operations Guide for the DAP8RC (Doc. 8187) for details.
Communication Setup
To upload a SIMPL Windows program or the
example program for the DAP8RC, it is
necessary to establish communications with a
2-Series control system.
• Use a standard DB9 male to female
“straight-through” cable, to connect a
PC’s serial port to the control system’s
computer port.
• Use a 4-wire Cresnet cable to connect
the DAP8RC to the control system.
If communication cannot be established, refer to
the “Troubleshooting Communications” section
in the Operations Guide for the control system.

Crestron C2N-DAP8RC Digital Audio Processor with Room Control
Load the Example Program and Verify Operation
Download the DAP8RC example program from the Crestron FTP site (ftp://ftp.crestron.com/Examples).
Search for C2N-DAP8RC.Basic Example.zip.
The example program does virtually all of the functions that can be accomplished via the Digital Audio Tools
(DAT) software, and lets you immediately hear the results of your adjustments. It can serve as a model
program for those individuals who wish to do system setup and room balancing functions via a touchpanel.
NOTE: The supplied program is designed to work with a Crestron TPS-4500 touchpanel and a PRO2 control
system. If your system uses a different touchpanel and/or control system, convert the programs accordingly.
After downloading the example program,
load the .spz program to the control system,
and load the .vtz program to the touchpanel.
Refer to “Upload via Crestron Viewport” on
page 56 of the Operations Guide for the
DAP8RC (Doc. 8187) for details. Once
these programs are loaded, the touchpanel
main screen appears.
The MUTE button and the up and down
arrows at the lower right control the sound
being supplied to the available speakers
indicated by the LEDs in the upper right
corner. The gauge shows the relative sound
level.
The SOURCE SELECT area is used to
select the digital or analog audio material
connected to the unit’s input ports.
The UTILITY area lets you select the
AUDIO or VIDEO switching utilities, or
SYSTEM SETUP.
The TONE CONTROL area provides
controls appropriate to the chosen audio
source and decoding mode.
• To begin, select SYSTEM SETUP.
The display provides a set of
buttons you use to select the parts
of the system to be configured—
SPEAKER CONFIG, AUDIO
CONFIG, and EQ’S—plus
AUDIO SWITCH and VIDEO
SWITCH, which are used to set
the internal routing of audio and
video signals. Initially, the large
screen area to the right is blank.

• From the system setup display, select SPEAKER CONFIG to display the SPEAKER CONFIG
window. Use this screen to specify the speaker arrangement of your system and to set the crossover
frequency for the subwoofer.
• From the system setup display, select AUDIO CONFIG to display the AUDIO CONFIG window.
Use this screen to set up the volume trims, the delays, and the noise generator settings. These settings
are usually used together during room calibration. The VOLUME TRIMS specify the relative gain for
each speaker in the room. The DELAY X 1ms settings specify the delays needed to ensure that the
sound from all speakers reach the listener’s ears at exactly the same time.
Use the NOISE GENERATOR buttons to select the noise source. The default STD (Dolby) button
toggles to PINK. Press BYPASS to bypass all equalization filters and tone controls. Use the ON and
MUTE buttons to turn each speaker on and off.
• From the system setup display, selecting the EQ’s button displays the EQUALIZATION window
used to specify the various filter settings for each speaker in the system.
• From the system setup display, select AUDIO SWITCH to display the AUDIO SWITCHING
window used to select the analog source you wish to appear on the three possible outputs.
NOTE: Any output from the AUDIO CAT5 connector and the AUDIO OUT A and B RCA
connectors is stereo from the unit’s analog crosspoint and does not contain any surround sound
encoding. But, any analog audio routed to the AUDIO OUT B connectors will also appear on the
SURROUND SOUND OUT connectors unless a digital source is selected for the surround sound
processor. Digital sources, though, cannot appear on the analog outputs.
Select the analog source that will appear on the CAT5, OUTPUT A, and OUTPUT B audio output
connectors. You can also choose to mute the signal to those outputs.
The OUTPUT B CONTROLS section affects only the signals to OUTPUT B. The BASS, TREBLE,
and BALANCE controls are initially set to their middle positions; the VOLUME control is set to its
zero position.
The three buttons at the bottom provide both electronic and relay mute control of all outputs, and a
standard ‘loudness’ selection that provides emphasized treble and bass. The electronic mute reduces
the level of the output to –80dB (effectively silent); the relay mute opens the output circuits.
• After performing the system setup procedures, press RETURN to display the default main screen.
Use the SOURCE SELECT buttons to choose the desired audio source. When any of the digital
audio inputs are chosen as the source selection, the system automatically detects the encoding
method of the incoming signal and displays the appropriate decoding mode choices.
Room Calibration
After you have determined that the DAP8RC is functioning properly, the next step is to install it at the site
and to calibrate the DAP8RC to the listening area. This process, called room calibration, is a critical part of
setting up a home theater. Without proper calibration, the impact of a movie or musical soundtrack will lack
what the sound engineer had originally intended.
Calibration procedures are beyond the scope of this Quick Start. Instead, refer to “Surround Sound System
Setup” on page 25 of the Operations Guide for the DAP8RC (Doc. 8187) for detailed instructions.
