Device Specifications - Preliminary Information
QX2010
QXpander Processor
General Description
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
QXpander
technology to produce a
spatially widened stereo image from ordinary
left and right channel inputs.
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.
Features
