MITSUMI Q Xpander Processors MM1326, 1354, 1369 . U Monolithic IC MM1326, 1354, 1369 4 t e e h S Outline a at .D w w w Features Q Xpander Processors co m 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. 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) Package SSOP-20A (MM1326AJ) SDIP-22A (MM1326AD, MM1354AD, MM1354BD) SSOP-24A (MM1354AJ) SDIP-24A (MM1369AD, MM1369BD) Applications 1. Computer sound boards 2. Active speaker systems 3. TV game equipment and other amusement devices 4. TVs, monitors, audio ...
