The Surround Mode button scrolls through the avail- able surround sound modes when pressed repeatedly.

The surround modes are:

Stereo: The Stereo mode provides signals to the front left and right speakers and possibly the subwoofer.

Hall: In the Hall Surround mode, a realistic level of ambiance is added to a normal stereo source such as a CD or FM radio.

IIhas enhanced imaging and wider bandwidth surround signals than original Pro Logic. Dolby Pro logic II

is intended for use with most mov- ies and television programs that are designed to be listened to using Pro Logic decoding. In addition to the standard Dolby Pro Logic II, which is known as Prologic II Cinema(PLII-C). “Pro Logic II Cinema”(PLII-C) is opti- mized for movies and television. The GTP-860IIsupports two other ver- sions of Pro Logic II processing, which were designed for specific types of programs. “Pro Logic II Music” (PLII- M)mode was designed for use with regular stereo recordings and it can utilize all your speakers in your sys- tem when listening to a CD. “Pro Logic II Panorama” (PLII_P)is a version of Pro Logic II that is intended for use with movie playback that spreads the images from the front left and right speakers around to the surround speakers. The original Pro Logic pro- cessing mode is also available.

With any of the Digital Inputs, the GTP-860IIautomatically recognizes

if the selected source carries a Dolby Digital™ or DTS™ signal. Dolby Digital and DTS have six independent chan- nels available in total: Left, Center, Right, Surround Left, Surround Right and an “Effects Channel” (Subwoofer). With either Dolby Digital

5.1or DTS digital input, the Stereo, Dolby Pro Logic and Hall surround modes cannot be selected. The Dolby Digital signal allows for several chan- nel configurations. Most two-channel Dolby Digital recordings will allow the Pro Logic listening mode to be applied. If the GTP860II detects a Dolby Digital™ or DTS™ signal it will be indicated on the front panel dis- play in the surround mode section.
