Device Specifications - Preliminary Information

General Description

Applications

The QXpander QX2010 is a bipolar analog

stereo enhancement processor. This device is

part of the QX chip family offered by

QSound Labs, and uses the patented

Television sound systems (Stereo).

Semi-professional audio equipment.

Personal/portable audio.

Multimedia applications for PCs and

laptops.

Multimedia speaker systems.

Video Games.

QXpander^™technology to produce

spatially widened stereo image from ordinary

left and right channel inputs.

Pin Assignment

This audio enhancement is achieved while

using normal stereo signals and standard

stereo audio equipment. No special initial

encoding of the input signals is required, no

additional speakers are required, and no

special hardware is needed to produce

QXpanded audio.

A TTL-compatible control input is provided

to select QXpanded audio or a normal stereo

signal (bypass). The QX2010 is fabricated in

bipolar technology, and is offered in a 22 pin

SDIP standard package. A 20 pin plastic

SSOP package is available on request.
