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 QXpander™ technology to produce a spatially widened stereo image from ordinary left and right channel inputs.
The QX2011 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.
