Q Xpander Processors
Monolithic IC MM1326, 1354, 1369
Outline
These ICs are analog stereo enhancement processors. They use patented Q Xpander technology to create a
stereo image with depth in three dimensions from ordinary left and right input channels.
There is no need for any special playback equipment; the enhanced audio effect can be experienced using
standard stereo audio equipment.
This IC, produced by Mitsumi, faithfully incorporates algorithms developed by Q Sound Labs, Inc., the world
leader in sound enhancement.
Features
1. Sound spreading sensation can be varied at will using an external VR (MM1354, MM1369)
2. Pseudo-stereo effects can be obtained from monaural audio signals (MM1369)
3. Sound spreading sensation can also be varied with a VR for pseudo-stereo from monaural input (MM1369)
4. Q Xpander on/off and pseudo-stereo on/off switching at TTL level
5. Internal filter circuit for few external components (MM1369)
6. No need for input signal encoding or special external equipment; playback possible using ordinary stereo
equipment
7. Low-noise design:
55 µVrms with Q Xpander on (MM1326)
60 µVrms with Q Xpander on (MM1354)
