The CNAMPX-7x200 7-channel, 200 watts per channel surround sound amplifier is
the ideal companion product to the C2N-DAP8RC surround sound processor.
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.

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.

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.

+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.

“Set Net ID by TSID” Window
4. Click on the Search for Touch Settable Devices button. The system
searches the network and lists all TSID-enabled devices found. The list
is similar to the report produced by pressing F4 (Report Network
Devices); the first eight digits of each line constitute the TSID number
(hexadecimal form of the serial number).
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
Tool” window is displayed.

Rack Mounting
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.
NOTE: If rack mounting is not required, rubber feet are provided for tabletop
mounting or stacking. Apply the feet near the corner edges on the underside of the
unit.
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).
Two “ears” are provided with the unit and must be installed so that it can be rack
mounted. Refer to the illustration on the next page and complete the procedures to
attach ears to the unit. The only tool required is a Phillips screwdriver.

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.

Digital Audio Processor with Room Control Crestron C2N-DAP8RC
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.
