DIR (Digital audio Interface Receiver : QR01 / LC89055)
This circuit extract synchronized clock signals and data from SPDIF signal input.
QR01(LC89055) generates these signals, this chip supports 96kHz sample rate.
1st DSP (Digital Signal Processor for Dolby Digital, Pro Logic, DTS : Q601 / YSS912)
Q601(YSS912) decodes 6 channels audio from encoded data signal input.
Some effects are processed in addition to multi channel decoding on HALL, MATRIX, and MOVIE mode.
2nd DSP (Digital Signal Processor for THX processing : Q651 / ZR38601)
Q651(ZR38601) has the THX 5.1 processing functions. These functions include Re-equalization, Surround Timbre-Match-
ing, Adaptive Decorrelation, Bass Management, Bass Peak Level Manager, and Loudspeaker Position Time Synchroni-
zation.
Re-equalization takes the edginess or "brightness" out of your home cinema sound, compensating for the fact that sound
mixed for theatres will sound too bright when played back through flat response speakers in your home.
Timbre Matching matches the tone of your front speakers to your surrounds to compensate for the fact that only two surround
speakers are used in a typical Home Theatre system instead of a full array as in a movie theatre.
Adaptive Decorrelation gives a stereo "feel" when your surrounds are playing mono and automatically switches off when they
are playing stereo.
Bass Management Electronic Crossover allows you to use more compact, easier-to-place speakers, while sending bass to a
subwoofer system, improving frequency response, lowering distortion and increasing dynamic range.
Bass Peak Level Manager protects your subwoofer from overloading due to the great amount of bass a 5.1 soundtrack
delivers.
Loudspeaker Position Time Synchronization lets you easily set up your system for an optimum listening position, which is
difficult to achieve within the space constraints of most homes.
CODEC ( QK01 / AK4528)
The AK4528 is a high performance 24bit CODEC for the 96k Hz recording system . The ADC has an Enhanced Dual Bit
architecture w ith wide dynamic range. The DAC uses the new developed Adv anced Multi Bit architecture and achieves
low outband noise and high jitter tolerance by use of SCF (switched capacitor filter) techniques.
The DAC is used for surround Back Left & Right channel.
DAC (Digital to Analog Converter : QD01 / AK4356)
The AK4356 is a high performance six channels DAC corresponding to 96kHz sampling mode of DVD.
Two channels of them can operate up to 192kHz sampling fully correspond to DVD-Audio standards. The AK4356
int roduces the advanced mult i-bit architecture for
range, while keeping much t he same superior distort ion characterist ics as conventional Single Bit way.
In the AK4356, the analog out puts are filtered in the analog domain by sw itched-capacit or filt er (SCF) with high
to lerance to clock jitter. The analog out puts are full differential output , so the device is suitable for hi-end applications.
The DAC is used for Left, Right, Center, Surround Left & Right and Sub woofer channel.
CPU (Q691 / TMP93CW44ADF)
This chip controls some ICs in P604 and communicates with QU01.
Connect to QU01 with serial interface lines.
