Audio DSP IC501

Purpose:

· Down-mixing of six channel AC-3 into two (L/R) channels

· Dolby Prologic decoding

· Audio enhancements when there is no AC-3 received (this rear chan-

nel delay circuitry is only found in some models):

q Digital Cinema Soundâ gives you the illusion of various spatial room

environments

q Virtual Enhanced Surround (VES) for 3D sound with two speakers

q Enhanced Surround for a greater sense of presence from the normal

Dolby Prologic sound

· Digital coax and optical output

· Rear channel delay

· Front/rear level balancing

· Test tone generation

D/A Converters IC902, IC905 – IC907

Purpose

Converts the digital input to analog output when received.

Support Signals

All the D/A IC support signals go to the same pins of these ICs because

they are the same number IC (CXD8799).
