QXpander Processor

Device Specifications - Preliminary Information

General Description

•

Low noise: 60 uV_RMS.

single supply voltage, internal reference.

Few external components, low cost.

The QXpander^™QX2011 is a bipolar analog

stereo enhancement processor. This device

is part of the QX chip family offered by

QSound Labs, and uses the patented

Applications

QXpander^™technology to produce

•

Television sound systems (Stereo).

spatially widened stereo image from

ordinary left and right channel inputs.

Semi-professional audio equipment.

Personal/portable audio.

Multimedia applications for PCs and

laptops.

Multimedia speaker systems.

Video Games.

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.

The 2011 has a TTL-compatible bypass

control to select between QXpander

enhancement and normal stereo audio. An

analog “spread” control is provided to vary

the amount of QXpander enhancement. The

QX2011 is fabricated in bipolar technology,

and is offered in plastic 22 pin SDIP and 24

pin SSOP packages.
