Yamaha MT3X - Manual (Page 10)

MULTITRACK RECORDER SECTION
® dbx ON/OFF Switch
The dbx switch determines whether the MT3X’s
internal dbx noise reduction system is ON or OFF.
For normal recording and playback using the
MT3X, the dbx switch should be turned ON. This
provides a significantly improved signal-to-noise
ratio (as much as 85 dB) so your recordings will
sound cleaner and have much less tape hiss. For
dbx noise reduction to be effective, it must be
turned ON both during recording and playback. The
dbx switch may be turned OFF when playing back
tapes that were recorded on other equipment and
which are
not dbx-encoded.
® TAPE SPEED Switch
The TAPE SPEED switch selects either the stan­
dard 4.75-cm/sec cassette tape speed, or the
MT3X’s special 9.5-cm/sec high tape speed. Use
the standard (4.75) speed when replaying tapes
recorded on standard cassette recorders, or to ob­
tain maximum tape economy. When you want
maximum sound quality, use the high (9.5) tape
speed. The improvement in sound quality provided
by the high tape speed is significant, and we rec­
ommend that you use the high speed for all impor­
tant recordings.
® PITCH Control
The PITCH control varies tape speed by ±10%,
making it possible to “tune” material recorded on
the MT3X to match the pitch of musical instru­
ments, or to slightly lengthen or shorten the running
time of a recording to meet specific timing require­
ments. Tape speed is normal when the PITCH
control is set to its center click-stop position. Tape
speed is increased by sliding the control towards
the “+” end of the scale, and decreased by sliding
the control towards the end of the scale.
@ ZERO STOP Button
The ZERO STOP button provides a fast, easy way
to locate a specific location on the tape. This is
particularly handy in multitrack recording, since it is
necessary to repeatedly rewind the tape to the
same point to record overdubs (i.e. record a new
track while monitoring previously recorded tracks).
To use the ZERO STOP function, set the tape
counter (below) to “0000” at the point you wish to
locate by pressing the COUNTER RESET button.
Then, with the ZERO STOP function ON (the
ZERO STOP “ON” indicator in the central display
panel will light), the tape will automatically stop
from the rewind or fast forward modes when the
counter “0000” position is reached.
® AUTO PUNCH I/O Button
This button activates the MT3X’s automatic punch-
in/out function, making a simple operation to re­
record any section of a previously recorded track.
When the AUTO PUNCH I/O button is pressed —
after the punch-in and punch-out points have been
specified using the AUTO PUNCH MEMO button
(below) — the AUTO PUNCH I/O “I/O” indicator in
the central display panel will light, indicating that
the AUTO PUNCH I/O function is ready. If the
transport is now set running in the record mode in
the normal way, the record mode will automatically
be entered only during the specified section of the
selected track(s). See “Automatic Punch-in/out” on
page 24 for full details.
® AUTO PUNCH MEMO Button
This button is used to specify the start and end
(punch-in and punch-out) points for the MT3X’s
AUTO PUNCH I/O function. While running the tape
in the playback mode, press the AUTO PUNCH
MEMO button once to specify the punch-in point
(the AUTO PUNCH I/O “MEMO” indicator will
flash), and then again to specify the punch-out
point (the AUTO PUNCH I/O “MEMO” indicator will
light continuously). See “Automatic Punch-in/out”
on page 24 for full details.
® COUNTER RESET Button
The COUNTER RESET button resets the elec­
tronic tape counter to “0000” at the current tape
position.
