The C2N-DAP8RC provides digital surround sound processing along with CAT5
head end/local AV distribution and room control functions. The result is cost­effective surround sound in any room of the house.

Surround Sound Modes

The C2N-DAP8RC provides the following surround sound modes, permitting choice
of the format that best suits the entertainment medium selected, the specific
characteristics of the listening/viewing area, and the personal preferences of the
listener.

Dolby Digital 5.1

Typically, 5.1-channel audio consists of five discrete, full-range main channels (left,
center, right, left surround, and right surround) plus an optional band-limited low
frequency effects (LFE) channel for added bass (subwoofer). Dolby Digital
bitstreams deliver full frequency bandwidth main channels, from 3 Hz to 20 kHz,
and a limited frequency bandwidth LFE channel, from 3 Hz to 120 Hz.

Dolby Pro Logic

As a descendent of the advanced technology used in Dolby Stereo theaters, Dolby
Pro Logic Surround decoders give enhanced spatial and directional effects when
used in the home environment. Sophisticated logic steering techniques are used to
extend the impact of the soundtrack over a wider listening area. Wide separation,
smooth dynamic action, and proper spatial imaging are key characteristics of Pro
Logic decoders.

Dolby Pro Logic II

Dolby Pro Logic II creates five full-bandwidth output channels from two-channel
sources. This is done using an advanced, high-purity matrix surround decoder that
extracts the spatial properties of the original recording without adding any new
sounds or tonal colorations.

2 • Digital Audio Processor with Room Control: C2N-DAP8RC Operations Guide - DOC. 8187A

Crestron C2N-DAP8RC Digital Audio Processor with Room Control

Movie Mode

The Movie mode is for use with VCRs, television shows, and all programs encoded
in Dolby Surround. The result is an enhanced soundfield that approaches the quality
of discrete 5.1-channel sound.

Music Mode

The Music mode is for use with any stereo music recordings, and provides a wide
and deep sound space. The Music mode includes controls that allow the sound to be
tailored to individual listening tastes.

• Center Width. This control allows center-channel sounds to be positioned
between the center speaker and the left/right speakers over a range of eight
steps. Step “3” uses a combination of all three front speakers to give the
best vocal imaging and most seamless soundstage presentation, and is
recommended for most recordings. Step “0” places all center sound in the
center speaker. Step “7” places all center sound equally in the left/right
speakers, just as in conventional stereo.

• Dimension. This control allows the user to gradually adjust the soundfield
either toward the front or the rear. This can be useful to help achieve the
desired balance from all the speakers with certain recordings that may
contain either too much or too little spatial effect. Step “3” is the
recommended setting, which has no effect on the sound. Steps “4” through
“6” gradually move the sound forward, and steps “2” through “0” move the
sound toward the surrounds.

• Panorama. This control extends the front stereo image to include the
surround speakers for an exciting “wraparound” effect with side-wall
imaging. It is particularly effective for recordings that have strong left- or
right-channel elements in the mix, since these are detected and accentuated
by the Panorama process.

All three of the above controls may be used alone or in any combination. After
experimenting with them on a few programs, it is easy to understand their effect and
which settings are preferable.

Dolby Digital EX

Dolby Digital EX creates six full-bandwidth output channels from 5.1 channel
sources by adding a rear center channel. This is done using a matrix decoder that
derives three surround channels from the two in the original recording. The center
rear is matrixed into the rear 2-channels of the 5.1 soundtrack, like what Pro Logic
does with the front three channels in the Pro Logic mode. The decoder takes the right
rear and left rear information, which also contains the center rear information, and
extracts the information so that the center rear channel is active. Thus, sound will be
heard out of the center rear speaker as well as the right rear and left rear speakers.
For best results, Dolby Digital EX should be used with movie soundtracks recorded
with Dolby Digital Surround EX.

DTS 5.1

DTS 5.1 is a multi-channel digital signal format developed by Digital Theater
Systems, Inc., that provides channels for the front left, right, and center, surround left
and right, and LFE. The process used by DTS produces audio tracks that closely
match the original master recording, with very little data compression.

Digital Audio Processor with Room Control Crestron C2N-DAP8RC

DTS ES Discrete 6.1

With the DTS-ES Discrete 6.1 format, all 6.1 channels, including the surround back
(SB) channel, are recorded independently using a digital discrete system. The main
feature of this format is that because the SL, SR and SB channels are fully
independent, the sound can be designed with total freedom and it is possible to
achieve a sense that the acoustic images are moving about freely among the
background sounds surrounding the listener from 360 degrees. Though maximum
performance is achieved when sound tracks recorded with this system are played
using a DTS-ES decoder, when played with a conventional DTS decoder the SB
channel signals are automatically down-mixed to the SL and SR channels, so none of
the signal components are lost.

DTS ES Matrix 6.1

With this format, the additional SB channel signals undergo matrix encoding and are
input to the SL and SR channels beforehand. Upon playback, they are decoded to the
SL, SR and SB channels. The performance of the encoder used at the time of
recording can be fully matched using a high precision digital matrix decoder
developed by DTS, thereby achieving surround sound more faithful to the producer's
sound design aims than with conventional 5.1- or 6.1-channel systems. In addition,
the bit stream format is 100% compatible with conventional DTS signals, so the
effect of the Matrix 6.1 format can be achieved even with 5.1-channel signal sources.

When DTS-ES Discrete 6.1 or Matrix 6.1 encoded sources are decoded with a DTS­ES decoder, the format is automatically detected upon decoding and the optimum
playing mode is selected. However, some Matrix 6.1 sources may be detected as
having a 5.1-channel format, so the DTS-ES Matrix 6.1 mode must be set manually
to play these sources.

DTS Neo:6 Cinema

This mode is optimum for playing movies. Decoding is performed with emphasis on
separation performance to achieve the same atmosphere with 2-channel sources as
with 6.1-channel sources.

This mode is effective for playing sources recorded in conventional surround formats
as well, because the in-phase component is assigned mainly to the center channel and
the reversed phase component to the surround (left, right, and back) channels.

DTS Neo:6 Music

This mode is suited mainly for playing music. The front (left and right) channel
signals bypass the decoder and are played directly, so there is no loss of sound
quality, and the effect of the surround signals output from the center and the
surround (left, right, and back) channels add a natural sense of expansion to the
sound field.

Two-Channel

This mode is used to play stereo source material in its pure unprocessed form.

Low Frequency Effects (LFE)

In 5.1, 6.1, and 7.1 surround formats, the point 1 represents an extra channel for LFE
sounds (120 Hz and below) that is decoded and routed to a subwoofer (if present).
The LFE channel signal is added to any other low frequency signals routed to the
subwoofer from channels unable to produce effective low frequency sound.

Crestron C2N-DAP8RC Digital Audio Processor with Room Control

Parametric Equalizer

The parametric equalizer consists of eight channels (one for each speaker) of six
bandpass filter sections that permit you to correct for acoustic anomalies in the
listening area or in the speakers themselves, and/or to establish preset values that
enhance the sound conditions for favorite music or recording types.

The six bands are identical in function. Each delivers up to 12 dB of boost or
attenuation, has an adjustable bandwidth control (from .02 octaves to 2 octaves), and
a center frequency control range from 10 Hz to 20 kHz. Use each band anywhere in
the audio spectrum, not just pre-selected ranges as typically found on graphic
equalizers. In addition, you can select from among five filter types (low pass, high
pass, EQ filter, bass shelf, and treble shelf) or select no filter.

Room Control Options

The C2N-DAP8RC also functions as a Cresnet® room control interface to local AV
and other devices such as TVs, projectors, VCRs, and DVD players. The unit may
receive video and digital audio from the Crestron CNX-PVID8, as well as analog
audio from the CNX-BIPAD8, all via CAT5 cabling. In addition, it receives video,
digital audio and analog audio from local sources via standard RCA connections.
The unit’s built-in audio/video matrix switcher distributes these inputs to local
outputs.

One bi-directional RS-232 and four IR ports are provided. A current sensor input
accepts power status feedback from the optional CNXRMCS current sensor
(available separately). In addition, a powered IR input allows connection of the
optional CNXRMIRD IR sensor (available separately) to receive IR commands from
a Philips Pronto

®

with RC5 commands or a similar universal remote control, which
may be programmed to control any device connected to the Cresnet system.
Naturally, any Crestron touchpanel or pushbutton control panel may be used with the
C2N-DAP8RC as well.

Finally, the unit provides outputs for directing video and analog audio back to the
head end.

Setup

Network Wiring

CAUTION: Use only Crestron power supplies for Crestron equipment. Failure to do
so could cause equipment damage or void the Crestron warranty.

CAUTION: Provide sufficient power to the system. Insufficient power can lead to
unpredictable results or damage to the equipment. Please use the Crestron Power
Calculator to help calculate how much power is needed for the system.
http://www.crestron.com/dealer-tech_resources/power_calculator.asp

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 | Wiring Diagrams section of the Crestron website
(www.crestron.com)

When calculating the wire gauge for a network run, the length of the run and the
power factor (power usage in watts) of each network unit must be taken into
consideration. If multiple network units are to be daisy-chained, the power factors of
each unit must be added to determine the power factor of the entire chain. The length
of the run in feet and the power factor of the run (in watts) should then be used in the
following resistance equation.

NOTE: All network wiring must consist of two twisted-pairs. One twisted pair is the
+24V conductor and the GND conductor; 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 network conductors.

Identity Code

Every equipment and user interface within the network requires a unique identity
code (Net ID). These codes are two-digit hexadecimal numbers from 03 to FE. The
Net ID of each unit must match an ID code specified in the SIMPL Windows
program. Refer to “Setting the Net ID in Device Settings” on page 49 for details of
the SIMPL Windows procedure.

The Net ID of the C2N-DAP8RC has been factory set to 50. The Net IDs of
multiple C2N-DAP8RCs in the same system must be unique. Net IDs are changed
from a personal computer (PC) via the Crestron Viewport.

NOTE: For detailed information on establishing communication between the PC and
control system, refer to “Communication Settings” on page 55. If communication
cannot be established, refer to the “Troubleshooting Communications” section in the
respective Operations Guide for the control system.

There are two different methods for setting the C2N-DAP8RC Net IDs:

Method A (Cresnet address-settable ID), described below, requires that a single unit
be the only network device connected to the control system. This method is
necessary with a 2-Series control system upgrade file (CUZ) version prior to 3.008.
It is optional with later versions of the operating system.

Method B (Touch-Settable IDs), which begins on page 13, applies to C2N­DAP8RCs in a Cresnet system with 2-Series control system upgrade file (CUZ)
version 3.029 or later. These upgrades enable Touch-Settable ID (TSID)
functionality, which makes it possible for the control system to recognize a network
device via its serial number, which is stored in the device’s memory. This method
does not require that any devices be disconnected from the network; Net IDs may be
set with the entire Cresnet system intact. This method requires the use of the
Crestron Viewport version 3.35 or later.

Use the appropriate method to set the C2N-DAP8RC Net ID.

5. As you enter either the serial number or TSID number of the device
that requires a change, the corresponding TSID or serial number
automatically appears in its appropriate field, and the list scrolls to and
highlights the device listing. The listing should show the device’s
current Cresnet ID.

6. Enter the Cresnet ID that the device should be set to and click OK. The
number you enter should appear on the list.

CAUTION: This function does not prevent you from setting duplicate IDs. Be sure
to check current assignments before entering the desired Cresnet ID number.

Serial Number to TSID Conversion

This utility is useful in a case where there are multiple devices of the same type on a
network, you need to locate a particular one, you know the TSID but not the serial
number, and your site installation list is based on device serial numbers. In this (or
the reverse) situation, do the following:

1. Open the Crestron Viewport.

2. From the Viewport menu, select Functions | Serial Number 
TSID Conversion Tool. The “Serial Number TSID Conversion

Crestron C2N-DAP8RC Digital Audio Processor with Room Control

Typical Hookup Connections for C2N-DAP8RC

Audio/Video Distribution

The C2N-DAP8RC provides local inputs and outputs for audio and video. Each local
video source input has a built-in video sensor. In addition, the unit provides a contact
closure type input that can be used with the CNXRMCS current sensor to detect the
power status of a high power device such as a television.

Typically, the C2N-DAP8RC receives video and digital audio from the CNX­PVID8, as well as analog audio from the CNX-BIPAD8, all via CAT5 cabling. In
addition, it receives video, digital audio and analog audio from local sources via
standard RCA connections. The unit’s built-in audio/video matrix switcher
distributes these inputs to local outputs.

NOTE: For additional information on video connections over CAT5, refer to the
latest version of the Crestron CAT5 Wiring Reference Guide (Doc. 6137) which is
available from the Downloads | Product Manuals section of the Crestron website
(www.crestron.com).

NOTE: The coax connection to audio inputs A and B and the optical connection to
inputs C and D carry the same signal type, S/PDIF, but Toslink cabling is only good
up to a maximum of 10 meters; the coax version can go 10 - 15 meters. This should
be considered in your hookup planning.

The following paragraphs and the audio and video routing diagrams below and on
the next page describe signal distribution arrangements that are typical for the C2N­DAP8RC. Refer also to the Typical Surround Sound Configuration diagram on page

20.

Distribution of Analog Audio to/from the Head End

Analog audio from distributed source devices is supplied by the CNX-BIPAD8 (or
CNX-PAD8) via CAT5 to the C2N-DAP8RC, then passed through a Crestron
amplifier (CNAMPX-7X200), and delivered as speaker level audio to the local set of
speakers. Analog audio can be directed from the C2N-DAP8RC back to the CNX­BIPAD8 directly, via CAT5.

Distribution of both Analog and Digital Audio from the Head
End

The C2N-DAP8RC also allows the user to choose digital audio as a video source
from the head end. In the room, the digital audio is supplied to the C2N-DAP8RC
surround sound decoder, passed through the CNAMPX- 7X200 amplifier, and
distributed to the local speakers. The listener can only select digital or analog audio
at any given time.

Speaker Types

Different speaker types have different sound reproduction characteristics, which
affect their performance in a home theater environment. Crestron makes no specific
recommendations, and provides the following information for reference purposes
only.

To create the most realistic surround sound experience, it is recommended that you
match your speakers’ tonal characteristics. This is also known as ‘timbre matching.’

Direct Radiating

Direct radiating speakers provide a focused image, which makes it relatively easy to
detect the general location of the sound (localization). This opposes the type of open
sound you would expect in a large theater or concert hall.

Bipolar

Bipolar speakers have drivers on opposite sides of their cabinets, wired in phase, and
provide a diffuse sound. Sound radiates from both sides, so the sounds seem to be
coming from all around instead of from a specific location. Because the sound is
very open, it creates a larger ideal listening area, and speaker localization becomes
more difficult.

LEFT
SURROUND

LEFT
FRONT

CENTER

RIGHT

FRONT

SURROUND

RIGHT

Dipolar

Dipolar speakers also have drivers on opposite sides of their cabinets and provide a
diffuse sound. These speakers operate 180°out of phase and create a sound field that
is more open than either the direct radiating or bipolar types. These speakers are
typically used in surround channel applications, and speaker localization becomes
the most difficult. This type of speaker is not recommended for front channels.

Subwoofers

Subwoofers are specially designed to reproduce the lowest ranges of audible
sound-usually from 120 Hz down to 20 Hz. These speakers are either powered or
non-powered. Non-powered subwoofers require an external amplifier and power
supply. Subwoofer output typically includes the information from the decoded LFE
channel and will include the low frequency information from the left, right, center
and surround channels when the speakers for those channels are unable to reproduce
the low frequency sounds, and bass management is enabled.

Speaker Arrangements

Refer to the diagram to the left of this paragraph and arrange the speakers in the
listening area according to these general guidelines. Refer to the instructions given in
“Surround Sound System Setup” on page 26 for optimum placement.

• Place front speakers so their front surfaces are as flush as possible with the
front of the viewing screen, and at an angle to the listening position of 45 to
60 degrees, with the primary drivers at ear level. Refer to manufacturer’s
instructions. Most recommend placement one to three feet from the wall.

• Depending upon the type of speakers used, surround speakers are usually
placed slightly behind and above ear level of the primary listening position,
approximately six feet above the finished floor.

at or slightly above ear level, approximately six feet above the finished
floor.

• Place the subwoofer according to the owners manual supplied with the
speaker.

Video Input Compensation for CAT5 Inputs

After the system is connected, it may be necessary to adjust the video input
compensation pots on the C2N-DAP8RC to achieve the best picture on the monitor.
This requires a narrow slotted screwdriver and an audio/video calibration DVD (or
laser disc). Crestron recommends one of the following:

• Avia Guide to Home Theater, from Ovation Software (www.ovationsw.com)

• Video Essentials, from DVD International (www.videoessentials.com).

To adjust the video input compensation:

1. Place the calibration disk in the system's DVD player.

2. Search the DVD for the chapter that displays the multi-burst pattern, as

shown in the following figure:

Refer to the note on page 55 for a
definition of Viewport.

NOTE: For S-video and component video sources, be sure to adjust the pot for
luminance compensation first (VIDEO INPUT COMP 1). The pots for chrominance
compensation should be adjusted last.

3. While the pattern is being displayed on the monitor, use the

screwdriver to adjust the VIDEO INPUT COMP 1 compensation pot
until the line intensity on the monitor appears uniform. Note the
numeric value.

4. Adjust the other two compensation pots (VIDEO INPUT COMP 2 & 3)

to the same value as the VIDEO INPUT COMP 1 compensation pot.

Universal Remotes

The C2N-DAP8RC can communicate with any universal remote control transmitter
that uses standard RC5 code, as well as some Sharp codes. An RC5 code is 14 bits
long and includes a 5-bit address (or “System Number”) and a 6-bit “Command
Number.”

The setup procedure for a universal remote is completed in two steps. First, the
Crestron Viewport is used to verify that the transmitter sends an identifiable code
that is compatible with the C2N-DAP8RC. Second, the buttons on the transmitter
are mapped so that they can be programmed in SIMPL Windows.

Operations Guide – DOC. 8187A Digital Audio Processor with Room Control: C2N-DAP8RC • 23

Digital Audio Processor with Room Control Crestron C2N-DAP8RC

NOTE: The Philips Pronto model transmitter contains built-in RC5 commands for
out-of-the-box use. The Pronto transmitter’s RC5 System Number is equivalent to
the Crestron Transmitter ID; similarly, the RC5 Command Number is equivalent to
the Crestron Button ID. This means that setting up the Phillips Pronto requires only
the code verification procedure described below, but not the mapping procedure.

NOTE: The Phillips Pronto can also generate non-RC5 codes.

Code Verification

All IR transmitters provide manufacturer’s documentation that lists IR codes by
device and manufacturer. Code verification involves choosing the appropriate code
so that the transmitter can communicate with the C2N-DAP8RC. This requires the
following:

• Crestron interface box, such as C2N-DAP8RC, connected to CNXRMIRD

• PC running the Crestron Viewport. The Crestron Viewport is available as a

pull-down command from SIMPL Windows or Crestron VisionTools
Pro-e (VT Pro-e), or as a standalone utility

• Crestron control system connected to the PC (the control system should be
running a valid SIMPL Windows program so that the C2N-DAP8RC can be
polled)

The procedure is completed as follows:

1. From the Viewport Diagnostics menu, select Identify Transmitter ID. The
Viewport will check the baud rate and then display the "Transmitter
Identification" window.

2. Point the transmitter at the CNXRMIRD and select a code, as outlined in
the manufacturer's documentation.

®

3. Press a button on the transmitter and take note of the "Transmitter
Identification" window.

4. If no activity is listed next to Button Action, the code is not acceptable.
Repeat steps 2 and 3 with another code. If activity is indicated next to
Button Action with each button press, the code was successfully
programmed.

Once the code has been successfully programmed, the transmitter is automatically
assigned a unique hexadecimal Transmitter ID that can range from 00 to 3F.

Surround Sound System Setup

After completing the hardware hookup procedures, perform these procedures to set
the C2N-DAP8RC surround sound default values according to the actual
environment of the listening area.

Crestron recommends the use of its Digital Audio Tools program (DAT) to configure
the surround sound system because of the program’s simplicity, speed, and ease of
operation. However, Crestron also supplies an Example Program with the C2N­DAP8RC that can demonstrate the various features of the unit and serve as a model
program for those individuals who wish to do the system setup and room balancing
functions via a touchpanel.

xample Program

NOTE: Crestron recommends setting the analog parameters of the C2N­DAP8RC in only one way—either through the DAT software or through the
SIMPL Windows program. However, if you must allow both, please read and
understand this warning. There are some subtleties that must be handled in a way

that is a bit different from what you may be familiar with when using similar
devices. For example, if you intend to directly set the C2N-DAP8RC <Volume>
analog input in your program, keep in mind that the <Volume_FB> signal can be set
to a different value through some other method (e.g., using the DAT software). In
other words, the C2N-DAP8RC actually stores these parameters, as opposed to a
CNXVTC-3 or ST-VC, where the value is stored solely in the control system. If you
were to just use an Analog RAMP symbol and send the output of the RAMP to the
<Volume> input and jam it with the <Volume_FB> output of the C2N-DAP8RC,
Oscillations might result between the RAMP and the actual <Volume_FB> value
from the C2N-DAP8RC. This could cause damaging volume levels to be sent to
your speakers.

Instead, use the "Analog Increment with Optional Feedback" (AINC) symbol.
Connect the <aout> output of the AINC to the <Volume> input of the C2N-
DAP8RC, then connect the <Volume_FB> output of the C2N-DAP8RC to the
<[FbckSignal]> input of the AINC. This way, the program will always be updated
with the true value of the C2N-DAP8RC. The same applies to any analog value that
can be changed from two places (EQ, Trim, etc.).

Test Equipment

No matter which method is used to set up the surround sound system in the listening
area, the following items are required:

• SPL (Sound Pressure Level) Meter. Used to measure sound in decibels
(dB). This is used to calibrate the speakers so each produces the same sound
level at a given volume setting.

• Tape Measure. Used to measure distance from speakers to main listening
position.

The following equipment is recommended to optimize the performance of the C2N­DAP8RC relative to the listening area, speaker arrangement, and the user’s
preferences:

• Audio Spectrum Analyzer. Used to “see” a speaker’s frequency response in
a room. This is used with equalizers to adjust for a proper room response.

26 • Digital Audio Processor with Room Control: C2N-DAP8RC Operations Guide - DOC. 8187A

Crestron C2N-DAP8RC Digital Audio Processor with Room Control

• Avia Guide to Home Theater, from Ovation Software
(www.ovationsw.com)

OR

Video Essentials, from DVD International (www.videoessentials.com).

The Avia Guide to Home Theater and the Video Essentials DVD discs provide
information and extensive instructions, including video test patterns and audio test
signals, for setting up a home theater environment.

Crestron Digital Audio Tools

The Crestron Digital Audio Tools software program is available from the Crestron
website. This program allows you to customize the configuration of the audio
processor to match the requirements of the listening/viewing area. You can specify
the speaker configuration, adjust the delay settings (to permit sound from all the
speakers to reach the listener at the same time), select the decoding mode for every
signal type input, and adjust the output setting (gain) for each speaker. The program
also provides the easiest method to configure the 8-channel, 6-band parametric
equalizer that lets you set the frequency, gain, bandwidth, and filter type for each
speaker to balance the listening area.

Refer to the help file that accompanies the software for more detailed information.

Setup Procedures

Setting up the C2N-DAP8RC surround sound processor consists of a number of
steps that need to be accomplished in the order presented here.

1. Place an SPL meter at the designated “sweet-spot” location in the room.
Measure the distance, to the nearest half foot, from the SPL meter to each
speaker in the room, including the subwoofer.

2. Launch the DAT program, and set communications parameters as described
in “Communications” on page 31.

3. Specify the room speaker arrangement as described in “Speaker Sizes / Bass
Management” on page 33.

4. Using the measurements obtained in Step 1 above, set up the system delays
as described in “Delay Settings” starting on page 34.

5. Select Tools | Realtime Mode from the menu bar (or click the Realtime
Mode icon on the toolbar). Then, select Tools | Source/Noise Steering (or
click the Source/Noise Steering icon), and use the information given in
“Source/Noise Steering” on page 28, to send pink noise to each speaker to
verify that the speakers are connected and functioning.

6. Using the instructions in “Using Source/Noise Steering for Calibration” on
page 30, and in ”Room Calibration” on page 34, perform room calibration
procedures.

7. Perform the instructions given in “Input Settings” on page 35 to set the
input levels for each of your audio sources.

8. Perform the instructions given in “Output Settings” on page 37 to set the
relative gain for each speaker in the room for each decoding mode.

9. Follow the instructions given in “Graphic EQ” on page 38 to specify the
number of graphic equalizers to be used in the system and to set their
gain/attenuation level.

Operations Guide – DOC. 8187A Digital Audio Processor with Room Control: C2N-DAP8RC • 27

Digital Audio Processor with Room Control Crestron C2N-DAP8RC

10. Refer to “Parametric Equalizers” on page 39 adjust the frequency response
interaction within the room for each speaker in the system.

DAT Program Procedures

After launching DAT, either open an existing program for the C2N-DAP8RC, or
start a new program and choose the C2N-DAP8RC template. The following
paragraphs describe the features and functions of the DAT program. Use the DAT
software to perform the setup procedures for the C2N-DAP8RC in the order
specified in the previous section.

Toolbar Icons

The following paragraphs describe some of the unique toolbar icons that provide
quick access to important digital audio tools functions.

Realtime Mode

The Digital Audio Tools Realtime Mode permits all changes to be transferred to the
device immediately. This is especially useful during calibration of the room

To select Realtime Mode, click the Realtime Mode icon on the Digital Audio Tools
toolbar, or select Tools | Realtime Mode. The system displays the following
message:

As suggested in the message, synchronize the application and the device by
performing a “Send To Device” or “Load From Device” transfer from the
Communications tab screen before attempting any real-time equalizer configuration
changes. Refer to “Communications” on page 31 for additional details.

Source/Noise Steering

The Digital Audio Tools program “Source/Noise Steering” window is for selecting
internal noise and external audio sources for calibrating the other parameters in the
system. Refer to “Using Source/Noise Steering for Calibration” on page 30. The
option is only available if you are working in Realtime mode. Clicking the
Source/Noise Steering icon displays the screen shown on the next page.

28 • Digital Audio Processor with Room Control: C2N-DAP8RC Operations Guide - DOC. 8187A

Crestron C2N-DAP8RC Digital Audio Processor with Room Control

This screen lets you select any available source signal from any of the C2N­DAP8RC audio ports or internal noise and direct it to a particular speaker to enable
setting the filters for optimum response.

If you select one of the Internal Noise sources (Pink or Dolby), the Source Select
drop down list is dimmed and unavailable.

If you select the Internal Noise Off setting, you may instead select an external audio
source from any of the ports and select a speaker for the left channel of that audio
source to be routed to. You would use this if you wanted to calibrate your system
using an external noise source (i.e., a CD or DVD or calibration tool) or with a
specific music or movie track.

View Error Log

Clicking this button displays the error log (if one exists) as shown in the following
illustration:

Mute

Mute on the toolbar acts as a toggle. Clicking this icon immediately mutes the sound
in all channels; clicking it again turns mute off.

Mute can also be accomplished by selecting Tools | Mute from the menu bar, or by
pressing F8. To turn Mute off, you must select Tools | Mute again or press Shift F8.

Operations Guide – DOC. 8187A Digital Audio Processor with Room Control: C2N-DAP8RC • 29

Digital Audio Processor with Room Control Crestron C2N-DAP8RC

The Mute button on the lower right of all screens is intended as a “panic” button to
prevent damage to speakers in the event of sudden large increases in sound level,
which can occur when switching from one sound source to another. Pressing this
button again does not turn mute off. Turn mute off, after the problem is resolved, as
stated above.

Using Source/Noise Steering for Calibration

Calibrating a room 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.

The Source/Noise Steering feature gives you three options to choose from to suit
your calibration needs. The definitions below give you the function of each type of
noise and its intended use for system calibration. The Source/Noise Steering feature
should be used with an SPL Meter and/or a Real Time Analyzer (RTA) for the best
possible calibration of the room.

Pink Noise:

Pink noise is sound that is comprised of a random signal, with all audio frequencies
present, over time, and at various signal levels. It provides equal energy per octave to
provide a flat response over all frequencies. (Refer to Graph 1 after the next
paragraph for visual reference.)

The main function of pink noise is to calibrate a speaker’s interaction within its
given room. The reason that pink noise is used over other generated noises such as
white noise is because of its equal power to all octaves. This makes it easier to
calibrate for a flat plot on a real time analyzer, since the level will be uniform across
every octave. Pink noise is provided by DAT software or you can use an external
source such as a DVD or CD. This would be used with the Room Calibration, Output

Dolby Noise:

Dolby Noise is Dolby Laboratories version of noise intended for calibrating a room
that uses only Dolby’s Surround formats for its listening modes. Dolby specifically
created this noise to represent what a home theater frequency response should be. A
flat response is not intended when using this noise in calibration of a room.

White Noise (External Source Only):

White noise is a sound that is comprised of a random signal, with all audio
frequencies present, over time, and at various signal levels. It provides equal energy
per Hz, which will give a 3 dB per octave increase starting from the lower frequency
range (20 Hz) to the upper frequency range (20,000 Hz). (Refer to Graph 2 after the
next paragraph for a visual reference.)

CAUTION: White noise is used to calibrate electronic equipment. It provides a
signal to measure levels and drives the circuitry at all signals simultaneously. IT
SHOULD NOT BE USED TO CALIBRATE SPEAKERS IN A ROOM. It can cause
a speaker’s tweeter to burn out and cause undesired response in the room due to the
levels you would set based upon the calibration.

Communications

The Communications tab allows you to define the settings for communication with
the C2N-DAP8RC in order to download existing files and upload new ones. It is
important that you set the communication parameters first before doing any of the
other setup procedures.

Operations Guide – DOC. 8187A Digital Audio Processor with Room Control: C2N-DAP8RC • 31

Digital Audio Processor with Room Control Crestron C2N-DAP8RC

Set up for communications as follows:

1. Initially, the Pass To check box is not selected indicating a direct
connection from your PC to the C2N-DAP8RC. Select Pass To if your PC
and the C2N-DAP8RC are connected through the control system via
Cresnet. Make certain the Cresnet ID setting is correct (50 is the default for
the C2N-DAP8RC). Refer to “Identity Code” on page 12 for more
information on setting the Cresnet ID.

2. Click on the Connection Settings Viewport Settings button to display the
“Port Settings” window. Select RS-232 as the connection type. Verify that
an available COM port is selected, and that all communication parameters
and necessary options from the “Port Settings” window are selected as
shown in the illustration on the next page. Click the OK button to save the
settings and close the window.

3. Synchronize communication between the PC and the device by clicking the
Transfer Configuration Load From Device button. This transfers any
current settings of the C2N-DAP8RC to the DAT program.

NOTE: Before making any adjustments via the DAT program, immediately save the
program (use File | Save As) to preserve the current device settings. This is
especially important if you are working on a device that has already been configured
and you subsequently need to restore those settings.

This screen lets you specify the room speaker arrangement, and set the crossover
frequency for the subwoofer.

Click on the appropriate buttons to identify the existing speaker arrangement; use the
Crossover Frequency drop-down list to specify the crossover frequency for the

Operations Guide – DOC. 8187A Digital Audio Processor with Room Control: C2N-DAP8RC • 33

subwoofer (if present). The distinction between Large and Small speakers here is
their ability to provide effective sound in the low frequency range (120 Hz and
below), not their physical size. Speakers designated as Large will receive low
frequency signals. Low frequency signals appearing in channels with speakers
designated as Small will be filtered out and routed to the subwoofer. Check the
frequency range rating of all speakers to determine their proper setting.

Delay Settings

Select the Delays tab to display the following window.

This screen lets you specify the distance—in feet or meters—between the speakers
and the primary listener location (the so-called “sweet spot”). This is done to ensure
that the sound from all speakers reach the listener’s ears at exactly the same time.
Measure the distances and enter the values to the nearest half-foot (or nearest 0.15
meter); the software will calculate any necessary delays. Enter distances as
accurately as possible.

You may also enter the delays in milliseconds by using a Real Time Analyzer (RTA)
equipped to give a millisecond value from the time the sound was produced to the
time it reaches the listener’s position. One example of such a device is the Audio
Controls Iasys RTA.

Note that the delays are not sent automatically in Realtime Mode. Click on the Send
button to transfer the delay settings to the device.

Room Calibration

Any listening/viewing area has its own characteristics that can affect the quality of
sound reproduction. The goal is to analyze the room and compensate for any
unwanted effects (such as reflections from hard surfaces, and resonance at particular
frequencies) so the listener hears what was intended when the material was recorded.

34 • Digital Audio Processor with Room Control: C2N-DAP8RC Operations Guide - DOC. 8187A

Crestron C2N-DAP8RC Digital Audio Processor with Room Control

During room calibration, this screen lets you set the master volume (e.g., -10 dB) and
then modify the gain of each speaker in the system to make the sound of each
speaker heard at the same level. Generally, a calibration level is chosen between 75
dB and 85 dB when playing Dolby Noise and all speakers are adjusted to the same
level. The zero button to the left of the Front Left slider resets all speaker sliders to

0.00 dB; the Master Volume and LFE settings are not affected.

Input Settings

This screen allows you to set the input levels for analog audio sources. Using the
Input Level Gain (dB) adjustment properly lets you compensate for analog sources
with different input levels to obtain a seamless transition between sources at a given
volume level. This screen also allows you to specify decoding modes for the various
analog and digital inputs.

Operations Guide – DOC. 8187A Digital Audio Processor with Room Control: C2N-DAP8RC • 35

Digital Audio Processor with Room Control Crestron C2N-DAP8RC

Selecting the button to the right of the Input Source pull-down list produces a
window with a field where you can enter a specific name, such as CD Changer,
VCR, or DVD, to help you keep track of multiple sources.

Each input source signal type can be assigned a specific decoding mode. The signal
type for all analog sources is 2-channel. You can assign a decoding mode to each
analog source via the Decoding Mode drop-down list. For example, you may want
the input from your CD Changer to always be played in DTS-Neo:6 Music mode.

The C2N-DAP8RC automatically recognizes the signal type that appears on its
digital input sources. You can select the preferred decoding mode for each input type
for each source from among the available types. Certain types have limited decoding
modes available. For example, a DTS-ES Discrete input is limited to the DTS-ES
Discrete or user controlled decoding modes. Refer to the table on the next page for a
complete listing of the input modes and corresponding available decoding modes.

NOTE: The availability of decoding modes depends on your primary configuration
mode (5.1, 6.1, 7.1) and your speaker configuration settings. The available decoding
modes listed in the above table are based on a 7.1 primary configuration, with all
speakers selected as Large and the subwoofer selected as Present.

NOTE: For configuration settings, one or more signal type(s) and decoding mode(s)
are dimmed to indicate they are not applicable.

Output Settings

Select the Output Settings tab to specify the relative gain for each speaker in the
room for each decoding mode.

These settings allow you to make adjustments in the surround sound configuration to
suit your personal preferences.

To adjust the gain settings, either click on the slider controls and drag them to
achieve the desired setting, use the up and down arrow keys on the PC to adjust the
setting, or type the value in the window. The Zero button to the left of the Front Left
slider resets all speaker sliders to 0.00 dB (the Master Volume and LFE sliders are
not affected). Use the Decoding Mode drop-down to select among the available
modes to alter their default settings (if there are default settings).

The Panorama, Center Width, and Dimension values are only available for Dolby
Prologic II Music decoding. Center Gain is available only for DTS NEO:6 decoding
and is used to adjust the gain of the center channel. (Refer to “DTS Neo:6 Cinema”
and “DTS Neo:6 Music” on page 4.)

Panorama

This control extends the front stereo image to include the surround speakers for an
exciting “wraparound” effect with side-wall imaging. It is particularly effective for
recordings that have strong left- or right channel elements in the mix, as these are
detected and accentuated by the panorama process.

Center Width

This control allows center-channel sounds to be positioned between the center
speaker and the left/right speakers over a range of eight steps. Step “3” uses a
combination of all three front speakers to give the best vocal imaging and most
seamless soundstage presentation, and is recommended for most recordings.
Step “0” places all center sound in the center speaker. Step “7” places all center
sound equally in the left/right speakers, just as in conventional stereo.

Operations Guide – DOC. 8187A Digital Audio Processor with Room Control: C2N-DAP8RC • 37

Digital Audio Processor with Room Control Crestron C2N-DAP8RC

Dimension

This control allows the user to gradually adjust the soundfield either towards the
front or the rear. This can be useful to help achieve the desired balance from all the
speakers with certain recordings that may contain either too much or too little spatial
effect. Step “0” is the recommended setting, which has no effect on the sound. Steps
1 through 7 gradually move the sound forward, and steps –1 through –7 move the
sound toward the surround speakers.

NOTE: The Panorama, Center Field and Dimension settings are only used in
Prologic II music mode.

Graphic EQ

This tab lets you specify how many (0, 3, or 5) of the six available filters for each
speaker will function like a standard graphic equalizer (with fixed frequencies and
settable gain/attenuation only), and how many (the remainder) will function as
parametric equalizers with settable frequency, gain, bandwidth, and filter type.

If you select 0 bands, all six filters will function as parametric equalizers. If you
select 3 or 5 bands, the following warning appears:

When you click YES, the display includes the appropriate one of the two screens
shown on the next page.

38 • Digital Audio Processor with Room Control: C2N-DAP8RC Operations Guide - DOC. 8187A

Crestron C2N-DAP8RC Digital Audio Processor with Room Control

In either case, the filter frequencies are fixed, and the gain for each frequency is
adjustable from 5 dB to –10 dB. The default gain is 0 dB.

If you choose either three or five graphic equalizer filters, you can also specify up to
10 trim presets using the EQ Trim Preset drop-down list.

Parametric Equalizers

The Parametric EQ tab allows you to adjust the frequency response interaction
within the room for each speaker in the system. You can attempt to achieve a flat
room response, or you can enhance or attenuate the response at up to six different
frequencies. In general, a flat room response is not pleasing to most ears. The
purpose of achieving a flat response is to remove all unwanted audio conditions in
the equipment and listening environment before making adjustments to satisfy the
user’s personal listening preferences.

For each speaker in the system (up to eight), you can set the gain, bandwidth and
filter type at up to six different frequencies in the spectrum, for each of the five
preset listening modes. Use the Filter drop-down list to select the filter to be set. You
can set the frequency, gain and bandwidth values by typing them into the appropriate
boxes, or by clicking and dragging the control handles in the display.

The DAT software helps simplify a system setup by permitting you to copy and
paste filter or speaker or preset values from one to another.

Example Program

The Example Program for the C2N-DAP8RC demonstrates the various features of
the unit. The program also serves as a basic model for those individuals who wish to
do system setup and room balancing functions via a touchpanel. The program does
virtually all of the functions that can be accomplished via the DAT software, and lets
you immediately hear the results of your adjustments.

The example program for the C2N-DAP8RC is available from the Crestron FTP site
(ftp://ftp.crestron.com/Examples). Search for C2N-DAP8RC.Basic Example.zip.

The program is supplied designed to work with a Crestron TPS-4500 touchpanel and
a 2-Series processor. If your system uses a different touchpanel, convert the program
for that touchpanel.

Preparation

In preparation for running the Example Program, do the following:

1. Verify that all the necessary procedures detailed in “Setup” on page 11 have
been completed.

2. Verify that communication setup procedures described in “Communication
Settings” on page 55 have been completed.

3. After downloading the Example Program from the Crestron website, use the
instructions given in “Upload via Crestron Viewport” on page 57, to load
the .spz program to the control system and load the .vtz program to the
touchpanel.

Running the Example Program

Once the programs are loaded to the touchpanel and the control system, the main
screen appears on the touchpanel.

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 pane is used to select the digital or analog audio source
material connected to the unit’s input ports.

The UTILITY pane lets you select the AUDIO or VIDEO switching utilities, or
SYSTEM SETUP.

The TONE CONTROL pane provides controls appropriate to the chosen audio
source and decoding mode. For example, the DYNAMIC RANGE selections MIN,
STD, and MAX, shown in the illustration, apply the indicated amount of
compression for Dolby Digital sources, as follows:

 MIN provides the highest compression ratio, bringing dynamic range

close to that of a TV broadcast.

 STD provides the dynamic range recommended by sound engineers for

general home viewing.

 MAX provides the full dynamic range of a cinema.

System Setup

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.

Select the first button, SPEAKER CONFIG. The screen displays the SPEAKER
CONFIG window.

SPEAKER CONFIG Window

Use this screen to specify the speaker arrangement of your system and to set the
crossover frequency for the subwoofer.

Crestron C2N-DAP8RC Digital Audio Processor with Room Control

Click on the appropriate buttons to identify the existing speaker arrangement. Note
that the front and the surround speakers are treated as pairs. Select the appropriate
one of the X-OVER buttons to specify the crossover frequency for the subwoofer (if
present). The distinction between large and small speakers here is their ability to
provide effective sound in the low frequency range (120 Hz and below), not their
physical size. Speakers designated as large will receive low frequency signals. Low
frequency signals appearing in channels with speakers designated as small will be
filtered out and routed to the subwoofer. Check the frequency range rating of all
speakers to determine their proper setting.

Audio Configuration

Select the AUDIO CONFIG button. The screen displays the AUDIO CONFIG
window. Use this screen to set up the volume trims, the delays, and the noise
generator settings. These settings are used together during room calibration.

AUDIO CONFIG Window

Use the VOLUME TRIMS settings to specify the relative gain for each speaker in
the room. Settings range from –12 dB to 12 dB in 0.5 dB increments.

Use the DELAY X 1ms settings to specify the delays needed to ensure that the sound
from all speakers reach the listener’s ears at exactly the same time. Enter the delays,
from 0 to 15 milliseconds, for each speaker by using a Real Time Analyzer (RTA)
equipped to give a millisecond value from the time the sound was produced to the
time it reaches the listener’s position. One example of such a device is the Audio
Controls Iasys RTA.

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

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.

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 description, the PRO2 control system is used.

This section describes a sample SIMPL Windows program that includes a C2N­DAP8RC.

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.

exists in the program. Always ensure that the hardware and software settings of the
Net ID match. For Net ID hardware setting details, refer to “Identity Code” on page

12.

C2N-DAP8RC Symbols in Programming Manager

Programming Manager is where programmers “program” a Crestron control system
by assigning signals to symbols. Due to the extensive functionality of the unit, a
single C2N-DAP8RC symbol in SIMPL Windows would be too complex. Instead,
the C2N-DAP8RC is broken up into slots. In Program Manager, expand the C2N­DAP8RC to view the individual slots; then drag the desired symbol to Detail View.
The C2N-DAP8RC slots, sub-slots, and corresponding symbols are described in the
following paragraphs. Because of their complexity, the description of the symbols
for the Surround Sound Decoder symbol, Slot 08; the Speaker Settings symbol, Slot
09 Sub-Slot 1; the Full Parametric EQ Controls symbol, Slot 09 Sub-Slot 2; and the
Graphic EQ Controls symbol, Slot 09 Sub-Slot 3, are described in the Appendix
“Advanced Programming Symbols,” beginning on page 63, for those advanced
programmers who wish to program them in SIMPL Windows.

Slot 01: Built-in 4 Port IR Card

This slot can contain up to four IR devices, selected from the Crestron or User IR
Databases. The actual symbols associated with this slot vary depending on the
devices in the system. As a sample, the IR Device Symbol illustration after this
paragraph is for a system that contains a Sony DVD player (model DVD-S7000).
Typical of all IR devices, it has a number of inputs to control its many functions.
These inputs are driven by a user interface (i.e., touchpanel or an acceptable third­party transmitter).

These ports also support one-way RS-232 serial communication, up to 9600 baud.

IR Device Symbol

Slot 02: IR Receiver

This symbol is only used in systems containing an acceptable third party transmitter
(Pronto/RC5/Universal IR Remote). To include a compatible third party transmitter
as part of the program, you must first drop a wireless receiver (CNXRMIRD) from
the Wireless Receivers | Wireless Receivers (IR) folder of the Device Library into
slot 2. Then, from the Wireless Remotes (IR) folder, drop the Pronto/RC5/Universal
IR Remote symbol onto the CNXMIRD. The symbol, shown below, consists of a
number of outputs (presses), which correspond to the actual buttons on the
transmitter. Recall that when mapping the buttons on the third party transmitter, a list
was developed (refer to "Map the Universal Remote" on page 25 for the actual
procedure). That list needs to be transcribed to this symbol. Match the button ID
numbers from the list to the numbered press. These outputs are the driving source for
the IR devices.

Pronto/RC5/Universal Remote Symbol

Slot 03: DAP8 Video Switch

The DAP8 Video Switch is a 16x16 video matrix switcher built into slot 03 of the
C2N-DAP8RC surround sound processor. The symbol is illustrated on the next page.
The C2N-DAP8RC provides one CAT5 input, labeled VIDEO IN 1-2-3-4 (where
twisted pair #4 can carry digital audio) and 12 RCA video inputs labeled 5 through

16. The C2N-DAP8RC accepts any combination of composite, S-video, and
component video, and switches these sources to up to sixteen outputs. Typically, the
RCA inputs are connected to local video sources, while the CAT5 input receives
video and digital audio from the CNX-PVID8.

RCA 5d – 16d
No Source 0d

The C2N-DAP8RC also provides 12 video sensors, plus one SENS input for
connection of an external current sensor. The <Sense_In> outputs will go high
whenever the sensor detects the presence of a video signal on RCA inputs 5 through

16.

The <SENS> input is a TTL input with pull-up resistor, designed to sense a contact
closure.

Slot 04: Built-in RS-232 Port

This port serves two purposes: an RS-232 port for two-way communication with
serial devices, and a console port for upgrading firmware. (Refer to “Uploading and
Upgrading” on page 55.)

The symbol, shown below, is only used when the C2N-DAP8RC communicates with
a serial device. The bidirectional port supports baud rates up to 115K baud N81 and
has RTS/CTS handshake signals. The tables below and on the next page list the
inputs/outputs and their functional description. Input and outputs enclosed by
brackets ([…]) are optional.

[tx$] More advanced signal processing can be done through serial strings and

the tx$ input line on the symbol.

[enable] If signal is present on this input, it must be high to permit activity of the

symbol. If the signal is low, the symbol is disabled.

[break] Some devices use a break character before sending out any serial data.

Break characters are sent out the port separated pace parameter.

[rts] RTS is an output from the program to the C2N-DAP8RC RS-232 port when

the state of the RTS line is set.

Slot 06: DAP8 Analog Audio Switch

The DAP8 Analog Audio Crosspoint is a 6x3 stereo analog audio crosspoint built
into slot 06 of the C2N-DAP8RC surround sound processor. The DAP8 Analog
Audio Crosspoint allows each of three stereo outputs to independently select one of
six stereo audio inputs.

the form of serial data strings on this output line.

The C2N-DAP8RC provides one CAT5 connector, labeled AUDIO, for stereo audio
input and output. That is, one twisted pair carries stereo audio to the unit, and the
other twisted pair carries stereo audio from the unit. The remaining audio inputs are
RCA left/right connectors, labeled AUDIO IN 2 through 6.

In addition to the CAT5 audio output, the C2N-DAP8RCprovides two left/right RCA
outputs, labeled A and B. Output A flows directly from the crosspoint with no
additional processing. Output B is passed through a volume/tone controller on slot 07
of the C2N-DAP8RC. Thus output B can be adjusted for volume, bass, and treble.
Refer to “Slot 07: Audio Output B Controls” on page 54.

Analog audio that is sent to output B will also be sent to the C2N-DAP8RC's internal
DSP (digital signal processor) if analog source is selected. The DSP settings are
controlled by the Surround Sound Decoder on slot 08; in some cases, the
programming of the Surround Sound Decoder may affect the Analog Audio Switch
settings. For example, if the program selects a different analog audio source for the
DSP, then that source will also be sent to output B (and the feedback will be updated
accordingly).

To switch a source to an output, each <Src> analog is initialized to a value that
corresponds to the source, as shown in the following table.

Analog Audio Symbol Source Signal Description (in Decimal Format)

Operations Guide – DOC. 8187A Digital Audio Processor with Room Control: C2N-DAP8RC • 53

Digital Audio Processor with Room Control Crestron C2N-DAP8RC

For example, to route the CAT5 audio input to output B, use an Analog Initialize
symbol to set the value of <DSP/OutB_Src> to 1. (Here, if no digital audio source is
being used, the CAT5 audio will also be sent to the DSP.)

Similarly, to switch RCA input 4 to output A, initialize <OutA_Src> to 4.
The feedback signals report the currently selected audio source for each output.
Again, in the case of output B, the feedback signal will be updated if the DSP selects
a different analog audio source.

Slot 07: Audio Output B Controls

The Audio Output B Controls module is a volume/tone controller built into slot 07 of
the C2N-DAP8RC surround sound processor. The C2N-DAP8RC provides three
outputs for analog audio: one CAT5 output and two left/right RCA outputs labeled A
and B. Output A flows directly from the processor's internal Analog Audio Switch
without additional processing, while output B is passed through the Audio Output B
Controls volume/tone controller. The symbol is shown below.

Audio Output B Controls

Digitals

The <Mute-On> and <Mute_Relay_On> inputs cuts audio for as long as their
respective signal remains high. The <Loudness-On> input activates the loudness
function for as long as the input remains high, while the <Mono-On> input switches
the audio setting from stereo to mono.

Analogs

The <Volume> analog input sets the volume level from 0% to 100%, which
corresponds to a gain range of –80 to +20 dB. The other analog inputs control bass,
treble and balance settings relative to the 50% mark. That is, a <Balance> input with
a value of 50% results in even distribution of audio between the left and right
speakers (0% = full left; 100% = full right). Likewise, 50% indicates a neutral level
for <Treble> and <Bass>.

NOTE: The symbols for the surround sound processor’s Surround Sound Decoder
symbol, Slot 08; the Speaker Settings symbol, Slot 09 Sub-Slot 1; the Full
Parametric EQ Controls symbol, Slot 09 Sub-Slot 2; and the Graphic EQ Controls
symbol, Slot 09 Sub-Slot 3, are very complex. Crestron strongly recommends using
its Digital Audio Tools (DAT) software to configure these modules. However, they
are described in “Appendix: Advanced Programming Symbols” beginning on page
63, for those advanced programmers who wish to program them in SIMPL
Windows.

Crestron C2N-DAP8RC Digital Audio Processor with Room Control

Uploading and Upgrading

Assuming a PC is properly connected to the entire system, Crestron programming
software allows the programmer to upload programs and projects to the system and
touchpanel after their development. However, there are times when the files for the
program and projects are compiled and not uploaded. Instead, compiled files may be
distributed from programmers to installers, from Crestron to dealers, etc. Even
firmware upgrades are available from the Crestron website as new features are
developed after product releases. In those instances, one has the option to upload via
the programming software or to upload and upgrade via the Crestron Viewport.

NOTE: The Crestron Viewport utility accomplishes multiple system tasks, primarily
via an RS-232 or TCP/IP connection between the control system and a PC. It is used
to observe system processes, upload new operating systems and firmware, change
system and network parameters, and communicate with network device consoles and
touchpanels, among many other tasks. Viewport can also function as a terminal
emulator for generic file transfer. All of these functions are accessed through the
commands and options in the Viewport menus. Therefore, for its effectiveness as a
support and diagnostic tool, the Crestron Viewport may be preferred over
development tools when uploading programs and projects.

The following sections define how one would upload a SIMPL Windows program or
upgrade the firmware of the C2N-DAP8RC. However, before attempting to upload
or upgrade, it is necessary to establish communications.

Communication Settings

NOTE: For laptops and other PCs without a built-in RS-232 port, Crestron
recommends the use of PCMCIA cards, rather than USB-to-serial adapters. If a
USB-to-serial adapter must be used, Crestron has tested the following devices with
good results:

Belkin (large model) F5U103
I/O Gear GUC232A
Keyspan USA-19QW

Other models, even from the same manufacturer, may not yield the same results.

The procedure in this section provides details for RS-232 communication between
the PC and the 2-Series control system. If TCP/IP communication is preferred,
consult the latest version of the Crestron e-Control Reference Guide (Doc. 6052) or
the respective Operations Guide for the control system. These documents are
available from the Downloads | Product Manuals section of the Crestron website
(www.crestron.com). Refer to the figure on the next page for a typical connection
diagram when uploading files.

NOTE: Use a standard DB9 male to female “straight-through” cable.

To take advantage of all the C2N-DAP8RC features, it is important that the unit
contains the latest firmware available. Therefore, please check the Crestron website
(http://www.crestron.com/downloads/software_updates.asp) for the latest version of
firmware. Not every product has a firmware upgrade, but as Crestron improves
functions, adds new features, and extends the capabilities of its products, firmware
upgrades are posted. To upgrade the firmware, complete the following steps.

1. Make sure that “Communication Settings” that begins on page 55 has
been performed.

NOTE: It is possible to communicate with the C2N-DAP8RC directly from a PC,
using the Viewport and an STCP-501 interface cable (DB9 to RJ11). Use this
method if you are uploading/upgrading only to a C2N-DAP8RC that is already
installed and you do not need to communicate to any other devices on the network,
or uploading/upgrading to one or more C2N-DAP8RCs before they are installed. If
you encounter a communication problem, enter Alt-K a few times (3-4) to clear it.

the volume and gain settings for a CD source, for
example, to differ from those for a Dolby Digital DVD.

together to produce the output volume.

Sets the delay, in milliseconds, for the indicated
channel. The delay is adjustable within a range of 0
ms to 20 ms, although the Dolby recommendations
are 0 ms to 5 ms for the center channel and 0 ms to
15 ms for all other channels.

Certain Pro Logic decoding modes add a 10 ms
delay that is not displayed or accounted for here.

Sets the bass and treble settings for all digital output

Digital Audio Processor with Room Control Crestron C2N-DAP8RC

Slot 09, Sub-Slot 1 Speaker Settings Symbol

The C2N-DAP8RC Speaker Settings module is built into slot 09 of the C2N­DAP8RC surround sound processor. The digital input signals select the presence and
size of the system speakers as well as the LFE crossover frequency; the digital output
signals report the selections. Alternatively, the speakers can be configured via
Crestron's Digital Audio Tools software, with no programming in SIMPL Windows.

FUNCTION

Sets the type of filter or EQ, as follows:

Filter_Mode
Off (no EQ) 1
EQ Filter - boosts or attenuates

specified frequency, as in a
graphic equalizer band.

Bass Shelf - uniformly boosts or
attenuates all frequencies below
the Filter_Freq level. The amount
of modification is given by
Filter_Gain.

Treble Shelf - uniformly boosts or
attenuates all frequencies above
the Filter_Freq level. The amount
of modification is given by
Filter_Gain.

Low Pass - filters out all audio
above the Filter_Freq level.

High Pass - filters out all audio
below the Filter_Freq level.

Selects the center frequency. Valid values range
from 20 (20 Hz) to 20000 (20 kHz).

Controls the bandwidth of a given filter, and is
expressed in octaves. Although ‘bandwidth’
applies only to the EQ filters, the CN2-DAP8RC
can derive Q or slope from bandwidth to control
the sharpness of high pass, low pass, and shelf
filters. Use of uniform units permits clean
transitions between filter types, such as from EQ
filter to lowpass.

For EQ, lowpass, and highpass, bandwidths in
the range of 0.02 to 2.0 are appropriate. For the
shelf filters, a range of 1.0 to 3.0 is appropriate.
Smaller values represent a narrow band of boost
or attenuation; larger ones represent a wide band
of boost or attenuation.

Boosts or attenuates the center frequency, or
with shelving filters, all frequencies above or
below the center frequency. Valid values range
from -240 (-24 dB) to +240 (+24 dB).

The Preset# input defines the preset to be stored
or recalled; thus valid values range from 1
through 5, or 0 for no preset. The Preset#_FB
output reports the current preset.

Crestron C2N-DAP8RC Digital Audio Processor with Room Control

Slot 09, Sub-Slot 3, Graphic EQ Controls Symbol

The Graphic EQ Controls symbol allows you to define the characteristics of the
graphic equalizer filters and presets.

The symbol’s input and output signals are as follows:

Preset store/recall signals:

• Digital inputs: <Store_EQ>, <Recall_EQ>, <Recall_EQ1> through
<Recall_EQ10>

• Analog input: <Preset#>

• Analog output: <Preset#_FB>

Trim Values:

• Analog inputs: <EQ_1> through <EQ_6>

• Analog outputs: <EQ_1_FB> through <EQ_6_FB>

Operation of the module is described following the symbol illustration.

C2N- DAP8RC Graphic EQ Controls Module

The C2N-DAP8RC provides ten trim presets, where a trim preset is a set of all six
<EQ> values.

Operations Guide – DOC. 8187A Digital Audio Processor with Room Control: C2N-DAP8RC • 73

Digital Audio Processor with Room Control Crestron C2N-DAP8RC

On the rising edge of <Store_EQ>, the six trim band values will be stored in the
preset specified by <Preset#>. Valid values for <Preset#> range from 1 to 10. The
<Preset#_F> output reports the current trim preset.

On the rising edge of <Recall_EQ> the values stored in the indicated <Preset#> will
be recalled and propagated to the outputs. Here the <EQ_FB> outputs may have
different values than the inputs.

Alternatively, a rising edge of a <Recall_EQ#> (1 through 10) input will recall that
trim preset.

The <EQ> inputs adjust the gains of the 6 filters; thus <EQ_1> corresponds to filter
#1, <EQ_2> corresponds to filter #2, and so forth. The gains are adjustable within a
range of –10 dB to +5 dB, and are applied equally to 7 of the 8 channels (the
subwoofer channel is excluded). All trim band values propagate immediately to the
outputs.

Valid values for <EQ> range from -100 (-10 dB) to +50 (+5 dB). An <EQ> value of
0 (0 dB) means that the signal will pass unaffected. Values above and below 0 will
boost or attenuate the gain in increments of .1 dB. That is, changing the analog value
by 1 signifies a 0.1 decibel boost or attenuation.
