Operating instructions

4.2.7 Mixdown
The procedure for mixdown is the same as for playback of the initial tracks
(§ 4.2.3). Be sure to use the reproduce head (Repro mode) rather than the
record head (Sel·Rep mode) for best quality.
4.2.8 Cue Modes
4.2.8.1 Normal Cue Mode
When the machine is in Stop mode, pressing the CUE button on the
MTR-90III (not on the Remote Control Unit) activates the adjacent Cue
Wheel. The wheel can then be rotated clockwise or counterclockwise to
shuttle the tape between the Supply and Take-up reels for locating cue points,
matching edit points and so forth. The actual tape speed is proportional to
the degree of rotation.
1. Press the CUE button.
2. Turning the Cue Wheel clockwise move the tape in the forward direction.
Turning the Cue Wheel counterclockwise move the tape in the reverse
direction. The triangular indicators near the Cue Wheel indicate the
direction of the tape movement (forward or reverse). Turning the Cue
Wheel further increases the tape speed.
3. Return the Cue Wheel to its original position to stop the tape movement.
In order to exit Cue mode, press the STOP, PLAY, F. FWD or RWD button.
NOTE: If the head shields are up and the tape needs to be seen as it passes
over the heads, press the SHIELD button on the MTR-90III Transport.
NOTE: The above mode can be used for very fast or slow playback of a tape
beyond the ±20% allowed by the Pitch Control described in § 4.2.10.
4.2.8.2 Fast Cue Mode (Lifter Defeat)
This mode permits auditioning of the tape during FAST FORWARD or
REWIND modes by retracting the tape lifters and padding all the audio tracks
by approximately 20 dB.
1. While the machine is in Fast Forward or Rewind mode, press the CUE
button on either the MTR-90III or the Remote Control Unit to retract the
tape lifters.
2. The lifters will remain retracted for as long as the button is held pressed.
Release the button to extend the lifters again.
CAUTION: Be sure the monitor amps are turned off or the volume is down.
Otherwise programs recorded on the tape are reproduced as a high pitch
squeal which could cause damage to loudspeakers. The volume level of the
monitor speaker can be attenuated by setting SW4 on the BIAS CONTROL
PCB Assembly (#7). For details, please refer to Table 2-4 in § 2.1.
