BD3473KS2 (MAIN : IC53)
7.1ch Sound Processor
●
General Description
It is 8ch independence volume which is the most
suitable for the realization of 7.1ch surround system.
Low shock noise switching was realized by Micro-Step
Volume. 12 single-end input selector can cope with it to
the zone 3, dual-multi input selectors are built in, and
many sources of signal can be connected. Moreover, 2
band equalizer characters can be changed freely by
changing outside parts.
