H MECHANISM A PB AMP. SWITCHING OUTPUT Mechanism A in PB: “’H”
H MECHANISM B PB AMP. SWITCHING OUTPUT Mechanism B in PB: “H”
H In Dubbing mode (both in Normal speed dubbing and High speed dubbing) : ‘‘H”’
4 In High speed dubbing : “L”
CLOCK OUTPUT for Port Expander (clock pulse width : 500 ns or more. )
(For timing, see another section.)
DDRP AMP SWITCHING OUTPUT ON: “H" OFF: “L”
® With input of DCS ““B6’": ON
®@ With input of DCS ’B7"'/At the end of Recording : OFF
@ When DDRP of DYNAMIC SCAN INPUT is ‘H” : No operation
DATA OUTPUT for Port Expander (For timing, see another section.)
MUSIC DETECTION INPUT for Music Scan. When requested music is detected : '’H”
[Music Detection Time]
@ Presence (being played) of requested music is judged when ’‘H”’ continues for 150 msec or
longer after ‘’L”’ period of 10 msec or longer.
e@ Absence (play finishes) of requested music is judged when “L” continues for 10 msec or
longer after ’’H” period of 150 msec or longer.
e@ Music detection is prohibited for 200 msec after MS mode starts.
@ No operation in W305/W205 mode.

@ Pulse whose minimum edge width is 3.5 msec must be received without fail.
@ Auto Stop Period:
When COUNTER PULSE does not vary in reel motor rotation for the following period,
Auto Stop mode takes place:
In Fast Foward operation ( <j, DD , MS): 1.5 sec
{in Normal operation (PLAY, REC/PLAY) : 15 sec
In normal operation, counting is not operated for 3.5 sec after start of reel motor and auto
stop takes place 1.5 sec after the non-counting period for 3.5 sec.
