Overview

QS7779PM/CM NIPPON PRECISION CIRCUITS INC.

3D Stereo Enhancement and 3D Virtual Stereo Surround with Dolby Pro Logic and Mixed DVD (AC-3) Decoder OVERVIEW The QS7779PM/CM is an audio processor IC which implements a decoder for stereo matrix encoded source materials such as the Dolby Surround Pro Logic and mixed DVD (AC−3) with surround virtualization using QSound™ technology developed and licensed by QSound Labs, Inc.

This chip produces enhanced stereo sound for a stereo input signal and if the input signal contains matrix encoded surround sound, the chip decodes it and produces 3D virtualized surround sounds with two speakers.

Key Features

  • s s s s s Capable of decoding Dolby Surround materials such as Dolby Pro Logic or other matrix surround encoded materials (DVD/AC.
