Digital Surround Processor
Overview
LV1110NM digital surround processor developed miniature stereo components radiocassette combinations. major features built into this Bi-CMOS single-chip solution function switching, recording volume control, surround processing, karaoke processing, 3-band graphic equalizer, master volume control.
Features
built-in delay functions include input output filters, analog-to-digital digital-to-analog converters, delay lines with built-in memory, delay reverberation. Other functions available fixed matrix (L+R L-R) front mixing (choice level phase). These functions freely combined easily produce variety surround modes thus simulate wide range acoustic environments. built-in karaoke functions include vocal canceler, microphone echo, control I/O, other support audio multiplexing software.
