Transcription

1 AUDIO PROCESSOR with BBE ViVA+ GENERAL DESCRIPTION The is a TV audio processor with BBE ViVA+ High Definition 3D Sound process. BBE's traditional sound clarity enhancement technology is combined with the Mach3BASS process to bass enhancement and the new ViVA 3D process to create an authentic and exciting spatial effect. The contains all necessary functions to process TV audio signal such as volume control, tone control, balance, mute and AGC function.
