QX2015

Matrix Surround Stereo Decoder with

Surround Virtualization

Device Specifications - Preliminary Information

General Description

Fabricated using bipolar technology and

available in a plastic 16 pin SOP

packages. Other package options may be

offered upon special request.

The QSurround™ QX2015 is a bipolar

analog virtual surround processor using

QSound Labs patented technology to create

a spatial or widened surround sound

experience. This virtual surround experience

is achieved by first passive decoding the

individual surround channels from a matrix

encoded stereo signal, then the QSound

processing widens the front channel

information, and virtualizes the surround

channel, placing it to the sides and behind the

listener. If the source material is a standard

stereo recording, QSound’s high quality

stereo expansion, QXpander™, creates a

spatial or widened stereo image.

Applications
