depending on the source material.

Surround EX decoding is ONLY applicable to 2/2.0, 2/2/

.1, 3/2.0, 3/2.1 streams AND when there is one or two surround back channels available in the system.

Dolby Pro Logic II: Dolby Pro Logic II is a substantial enhancement to the original Pro-Logic process. In addition to full-bandwidth surrounds, Pro Logic II provides three unique user adjustable processing options: panorama; dimension; and center width. Used primarily in Pro Logic.

Dolby Pro Logic II-C (Cinema): This processing mode can create up to 6 full bandwidth channels from any stereo, 2 channel source, idea for use with movies.

Dolby Pro Logic II-M (Music): In music mode there are three additional adjustments.

Panorama provides an extension of the front stereo image to the surround channels creating an enveloping, wrap- around effect.

Dimension enables adjustment of the surround image between the front and rear of your room. Certain types of music benefit from smoother overall balance and a more natural sounding image.

Center width provides variable adjustment of the center channel image and location, to create a more seamless front soundstage as well as control of the sense of “width” across the L/C/R loudspeaker array. A phantom center image can also be created from just the left and right front speakers.

DTS: This compressed digital data format is similar to Dolby Digital. DTS also provides 5.1 channel surround channels and is available on compact disc, DVD and laser discs. Audio-only DTS discs may be used with any CD, LD or DVD player with a digital audio output, but DVD discs with DTS audio must be used on players with the “DTS Digital Out” logo.

DTS-ES:An extension of the original DTS format that adds an additional sixth, or center surround, channel to a soundtrack. DTS-ES Matrix 6.1 titles provide a surround back channel by a matrix decoding process, while DTS-ES Discrete 6.1 media deliver a true discrete center surround channel. Both DTS-ES formats are backwards compatible with the original DTS process, and will deliver a 5.1 channel output when no center or back surround speakers are available. Additionally, the user may force the system to decode a DTS-ES Matrix 6.1 stream or DTS-ES Discrete 6.1 stream using the DTS Digital Surround 5.1 channel

decoder, even if they have a surround back speaker(s) in their setup.

The GTP-880 will automatically sense the availability of either DTS-ES format and automatically switch the pro- cessing mode when required.

DTS NEO:6-C (Cinema): This processing mode can create up to 6 full bandwidth channels from any matrix-encoded 2 channel source. Additionally, this mode can produce the rear surround information from a 5.1 source.

DTS NEO:6-M (Music): In music mode it can expand stereo music material, into a multichannel surround experience.

Stereo: This mode provides conventional 2 channel signals from a stereo or downmixed multichannel to the left and right front speakers only. With an analog and digital input source, the signal is decoded (if AC-3 or DTS) and then downmixed (if a multichannel source) and then bass- management is applied which allows for the HPF on the front speakers to match the LPF set on the subwoofer. Delays are offered on the front and subwoofer channel in this mode as well.

Stereo 5: This mode is designed for use with stereo program material. It is designed to get maximum output from all your speakers. The rear speakers are driven with the same signal as the front left and right, while the center speaker is a monophonic summation of the front speakers.

Stereo 7: This mode is designed for use with stereo program material. It is designed to get maximum output from all your speakers. The rear speakers are driven with the same signal as the front left and right, while the center speaker is a monophonic summation of the front speakers.
