AC-Processor II Operation

Dolby Pro Logic II

Dolby Pro Logic II is a matrix decoding technology in which the updated digital matrix technology is applied and Dolby Pro Logic is further im- proved. It realizes excellent 5.1 channel reproduction of Dolby surround source as well as stereo sound sources such as CDs, thereby causing a surround channel to be full-ranged (20 Hz to 20 kHz) and become stereo. Therefore, you can enjoy any stereo sources with dynamic sound of 5.1 channel. According to a source to be reproduced, Music Mode or Matrix Mode can be selected.

●Music Mode

This mode is suitable for stereo sources like CDs. By optimizing frequency characteristics of the surround channel, a broader and deeper sound is assured. In addition, since broadness of the sound field varies with recording conditions of music sources, there is Adjusting Mode which makes a finer tuning available.

●Matrix Mode

This mode is suitable for AM/FM radio.
