SELECTOR3 This is a selective switch to select the output signal of Sout from BNRout,Dout and 3STEREO/MUTE. SELECTOR4 This is a switch to connect a noise sequencer output to ADAPTIVE MATRIX stage for level ajustment. Digital Deley Make 7 kinds of delay signal s.(15.4msec~196.6msec) The delay function and CLK signal stop at DELAY OFF MODE. This mode is for suppress bad effect of digital noize. FEEDBACK This is a switch to select feedback mode(ON/OFF) for SURROUND MODE . MODE SEL(MOS) This is a switch to select a feedback signal from surround signal and echo signal. VOL MIC MIX Delay Mix SW Control the ATT level of delay signal from 3dB to -∞ (12-step) This is a switch to mix miclophone signal to a main signal (Lch,Rch) This is a switch to select output or not a mixed signal to DOUT pin. MITSUBISHI ELECTRIC ( 17 / 20 ) C-62460-72E MITSUBISHI SOUND PROCESSORS M62460FP “Super Single Chip” Surround Processor with Dolby Pro Logic Decoder 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 -on *Transient noise common with power up occurs. RESET TIME Power up MUTE TIME Freed from resettung Freed from muting Internal delay time setting •At delay time setting change Delay signal before change Delay signal after change MUTE TIME Instruction to change delay time Freed from muting Internal delay 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.
