2. Connection of Zero-Crossing Detector and Timer Setting
"OR" of [Zero-cross Detector Strobe] or [Compulsion SW of Timer Circuit] moves
Internal Analog SW . When for example, suppose that it set to T=10msec.

In case of Pattern1, the Zero-cross Detector Strobe occurs with the Zero-cross Detector
Function, and SW is switched. But in case of Pattern2, the Timer Function switches the
Analog SW after T=10msec, for the Audio Input Signal didn't cut the Signal Ground after
T=10msec which were set with the timer.
