QX2012  
QXpander Processor  
Device Specifications - Preliminary Information  
General Description  
Features  
The Qxpander™ (QX2000 chip series) is a  
bipolar analog stereo enhancement processor  
using the patented Qxpander™ technique to  
produce a spatial or widened stereo image  
from ordinary left and right channel inputs or  
from a mono input. The QX2012 provides  
variable spread of the spatial or widened  
stereo image. Enhancement is achieved  
without any initial encoding of the input  
signals and no additional speakers are  
required.

activates the internal mono to stereo  
simulator.  
The QX2012 can be bypassed using the  
QEN/BYP  
digital control input  
. This allows  
the stereo input signal to pass through the  
chip unaltered.  
The QX2012 is fabricated using bipolar  
technology and is available in plastic 24 pin  
SDIP. Other package options may be  
offered upon request.

Normally, the QXpander™ is used in the  
preamplifier stage between the source and  
the stereo amplifier stages used to drive the  
speakers. The QXpander™ enhancements  
can be disabled using the bypass control  
allowing the unchanged input signal to pass

In ordinary stereo systems, the stereo image  
is formed between the left and right  
speakers, and is confined by the speaker  
positions (i.e., the "sound stage" is located  
between the two speakers). QXpander™ is  
designed to form the stereo image beyond  
the speakers, thus enlarging the "sound  
stage".

Using the spread control, the level of the  
stereo enhancement (width emphasis) can be  
adjusted to satisfy the listener. Figure 2
