QX-1  
QXpander Processor with Volume and Tone control  
Device Specifications - Preliminary Information  
Overview:  
The QX-1 is an audio enhancement and control IC featuring QSound Labs’ QXpander process. The patented  
QXpander technology produces a spatial or 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 and no additional speakers are required.  
Feature:  
·
Built in QXpander technology  
Stereo sound enhancement  
Electronic volume control  
2 band tone control
