Dolby Laboratories CD Player manual

DOLBY SURROUND PRO LOGIC mode:

Choose this feature when playing Dolby Pro Logic encoded movies and music (especially laser disc, video tapes and TV broadcasts with Dolby Surround sound). Most currently released video cassetles and many TV broadcasts include this feature. Dolby Pro Logic will not only give improved sound, it will give a clear perception of the position and direction of the original sound track.

Three types of centre mode are available when using the Dolby Pro Logic feature, NORMAL WIDE and PHANTOM. These options have programmed surround (delay) values for the centre channel. The delay (or echo effect) is different for each mode:

.The NORMAL mode gives true Dolby Pro Logic sound.

.The WIDE mode can be used to gives greater acoustic separation of the centre speaker-

.The PHANTOM mode diminishes the effect of hearing a true centre channel. The main left and right speakers give the effect of centre channel information.

One other Pro Logic mode is available:

.The DOLBY 3 STEREO mode creates a Dolby Pro Logic sound effect using just the left, right and centre channels. No sound comes from the surround channel speakers. You can still select normal or wide effect in this mode.

To select and cancel Dolby Pro Logic modes 1.Press the PRO LOGIC. PHANTOM or DOLBY 3

STEREO button to select the required mode.

2.Press NORMAL or WIDE buttons to select normal or wide effect (not available in phantom mode).

3.To cancel any Dolby Pro Logic mode. press the PRESET EQUALIZER button.

NOTE:

It is not unusual on some Pro Logic material to have little or no rear speaker output. This is normal and to be expected, as part of the overall effect created by the sound track producer.
