Denon HEOS Amp HS2 - Integrated Circuit Specifications; BD3473 KS2 IC Details

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.
●Features
 12 single end input selectors are built-in
(Possible maximum 18 single end with exclusion)
 Low shock noise switching was realized by
Micro-Step Volume
 Zone 3 is possible
 Dual-mult
i input selectors are built-in
 2 wire control copes with 3.3/5 V
●Applications
 Most suitable for the AV receiver, home theater
system
●Key Specifications
 Total harmonic distortion: 0.0004%(Typ.)
 Maximum output voltage: 4.2V(Typ.)
 Output noise voltage: 1.5uVrms(Typ.)
 Residual output noise voltage: 1.0uVrms(Typ.)
 Cross-talk between channels: -105dB(Typ.)
 Cross-talk between selectors: -105dB(Typ.)
