INPUT BALANCE NOISE SEQUENCER ADAPTIVE MATRIX
Function
Revises a level error between the input Lch and Rch for optimum decorder performance. A simple noise sequencer circuit for ajustment of output level. Contineuously analyze the two-channel matrixed audio input to determ ine the direction and relative magnitude of encoded soundfield. Possible to select 4 - center mode position. (WIDE,NORMAL,PHANTOM,OFF) This is the level ajustment volum of Cch and Sch. ( 0 to -30 dB : 1dB/step )

Modifide BNR
Function
This block restores the signal to its original spectrum while reducing noise and certain crosstalk signals in a final stage of the surround chain. Select a positive phase signal or a negative phase signal with DIGITAL SPACE SURROUND MODE. This is a selective switch to select the output signal of Lout and Rout from BY-PASS,PRO LOGIC,OTHER SUR and MUTE . This is a selective switch to select the output signal of Sout from S',L+R,L-R and MIC. This is a selective switch to select the output signal of Sout from BNRout,Dout and 3STEREO/MUTE. This is a switch to connect a simple noise sequencer output to ADAPTIVE MATRIX stage for level ajust-ment.
Make 7 kinds of delay signal s.(15.4msec to 196.6msec) The delay function and CLK signal stop at the time of DELAY OFF MODE. This mode is for suppress bad effect of digital noize.

AUTO MUTE FUNCTION
The IC carries out auto mute function at the time of powerring up, delay time setting change, and cancelling delay off mode, in order to suppress shock noise that the digital delay may produce. * At power up
* Transient noise common with power up occurs.
RESET TIME Power up Freed from resettung
MUTE TIME Freed from muting Internal delay time setting
* At delay time setting change Delay signal before change Delay signal after change
MUTE TIME Freed from muting Instruction to change Internal delay delay time time change
* At canceling delay off mode
MUTE TIME Canceling delay off mode Freed from muting
Mute time changes depending on set (or preset) delay time.
DELAY TIME 15.4 to 49.2 147.5 ,196.6 ms ms
