[8] Surround Mode

With the Surround Mode button the available surround sound modes can be selected. The selected surround mode is permanently indicated in the display area on the right side of the top line of the display. 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.

Pro Logic II: Dolby Pro Logic II is the new advanced version of Pro Logic, Dolby’s original surround matrix with center channel output. Pro Logic

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.

5 ch Stereo: This mode is designed for use with stereo program mate- rial. 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.

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.

[9] Bass/Treble Controls

The GTP-860IIis fitted with Bass and Treble tone controls to adjust the overall tonality of your system. The 12 o’clock position is ‘flat’ with no boost or cut and a detent indicates this position.

Rotate the control clockwise to increase the amount of Bass or Treble. Rotate the control counter- clockwise to decrease the amount of Bass or Treble. These controls affect the Left and Right Front chan- nels. The Tone controls do not affect recordings made using the Tape or Video line outputs.
