For digital power start-up control (reserve)
• +5STBY power ON/OFF control (L=ON / H=OFF: to reduce stand-by power) /
L=ON / H=OFF: to reduce stand-by power)
• Usually fixed to Low. The stand-by power is reduced by setting to HI after
completion of processing required for stand-by. (MCUSleep)
When AC IN and MCUSleep, “HighFix” is retained until power ON input takes
place.
• Fixed to Low to maintain the mute function
Front speaker relay control / Usually working as the expansion function of main
microprocessor. / All tuned OFF on the sub-microprocessor side when an abnor-
mality occurs or when started/terminated.
Center speaker relay control
Surround relay control
Zone speaker relay control
* ON inhibited at the same time as Front B speaker relay
Presence/Rear presence speaker relay control
Front B speaker relay control
* ON inhibited at the same time as Zone Speaker relay
Surround back / BiAMP relay control
Headphone relay control
DC TRIGGER output 1
DC TRIGGER output 2
Full mute control (Audio/Video) / Low: Mute on / Hi: Mute cancel
POWER AMP ON/OFF control / Low: AMP-ON
/ * When set to High, be sure to keep Speaker relay OFF.
/ (Headphone relay need not be OFF.)
/ When turning from OFF to ON, keep waiting until the speaker relay turns ON just
like when the power is started.
