Q Xpander Processors
Monolithic IC MM1434
Outline
From ordinary stereo signal input, each of the sound sources is expanded spatially to reproduce sound with a
sense of immediacy.
Algorithms developed by Q Sound are faithfully implemented in an IC produced by Mitsumi.
Features
1. Sound spreading is easily modified using an external VR.
2. Few external components required through use of active filters based on Mitsumi's bipolar technology.
3. Low cost achieved through improvements from previous model (MM1354) to VA.
Package
SOP-16A (MM1434XFBE)
Applications
Sound enhancement processor.
