This unit will process either digital audio streams (S/PDIF) or analog signals, and generate up to 7.1 surround sound preamp outputs. Designed for the ultimate in home theater entertainment, the C2N-DAP8 provides multiple surround sound modes for virtually any room size and speaker configuration, with unmatched accuracy to satisfy the most discerning ear. The functional summaries below and on the following page highlight the main features of the C2N-DAP8.

The C2N-DAP8 provides digital surround sound processing along with CAT5 head end/local AV distribution functions. The result is cost-effective surround sound in any room of the house. Surround Sound Modes The C2N-DAP8 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 a discrete, 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. 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. 2 · Digital Audio Processor: C2N-DAP8 Operations Guide - DOC. 8186 Crestron C2N-DAP8 · Digital Audio Processor 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 contain 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. 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. Operations Guide ­ DOC. 8186 Digital Audio Processor: C2N-DAP8 · 3 Digital Audio Processor DTS ES Matrix 6.1 Crestron C2N-DAP8 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. Whe ...
