MM1454 - Q Surround Processor

MITSUMI

Key Features

1. Virtual rear speakers allow reproduction of 3-dimensional sound through only two speakers when a Pro Logic encoded source is input. 2. Also reproduces wide sound for a normal stereo source. 3. 2ch input - 2ch output. 4. Few external parts due to use of the active filter created using Mitsumi's bipolar technology. 5. Low noise design Q Surround ON: 15µVrms OFF: 10µVrms 6. Simple structure results in small size and low cost. Package SOP-16B.

MITSUMI Q Surround Processor MM1454 Q Surround Processor Monolithic IC MM1454 Outline This is an analog IC virtual surround processor that faithfully reproduces the sound algorithm developed by Q SOUND Labs, Inc. In particular, when a stereo signal (L/Rch) encoded by Dolby Pro Logic is input to this IC, a virtual rear speaker is created spatially, and this allows reproduction of realistic, 3-dimensional sound from two speakers, without the addition of another speaker. Q Xpander technology allows deep, spatially wide sound for input of normal stereo signals, as well. * Virtual Dolby sound is a system developed by Dolby Labs, Inc.
