When both decks contain cassettes and the direction
mode is = or 3, when the deck playing reaches the end
of
tape, the other deck plays automatically.
Dubbing
Normal dubbing and high-speed dubbing from A to B are
possible with the DUBBING and HIGH-DUBBING keys.

mute operations are performed by pressing two keys at
the same time or pressing keys while the deck is operat-
ing.
Auto bias
The 400-Hz
and
10-kHz
record/play
levels are deter-
mined to set the optimum
bias for the tape. (Normal
tape)
CCRS
The CD can be recorded automatically at the optimum
level and bias.
Serial communication function

cording and playback are set with a tuner with a timer (T-
xxx), and instructions are transmitted to the deck by seri-
al communication.
CCRS operation mode setting function
Three states, FADE OUT, ERASE, CROSS FADE, can be
set with the FADE MODE
key.
Auto-bias recall function
The bias value of the previous auto-bias can be recalled
with the MEMORY RECALL. A reset can be performed
immediately when the same tape is used.
Save function
The tape direction and the recording level for each re-
cording source are saved.
i)
The tape direction of the last play/record is saved.
ii)
|The recording level is saved for each source. When
the REC VR key is pressed and the recording level
changes, the recording level data for the currently
selected source is rewritten. The recording source is
the tuner when the power is switched on because
the source in the deck amplifier selector memory Is
selected. Then, the source selected with the amplifi-
er selector becomes effective.
Multiplex automatic on/off
In the REC mode, a multiplex on/off pin (IC3) is set
low to control IC2 (system IC) when the amplifier
selector memory of a deck is set as a tuner.
It is set
high when normal operation mode and the selector is
set as other than a tuner in REC mode.
Two
speeds
(double-speed
recording),
NORMAL
and
HIGH, can be selected with the CCRS start key.
CCRS allows one or more discs to be used in each edit
mode when MULTI-DISC
EDIT is selected. (FADE OUT
and CROSS-FADE
modes only)
