TAPE DECK
20. SPEED AND EQUALIZATION SELECTOR
This is a six position rotary switch permitting the selection of the speed and equalization of the 4.2 in both
record and playback.
Possible settings are:
3 3/4 ips (9.525 cm/s)
7 1/2 ips (19.05 cm/s)
15 ips (38.10 cm/s)
For each of these speed selections there are two possible positions labelled I and II; these correspond to
different tape types.
For best quality recordings, the 15 ips speed is recommended.
For normal recordings, the 7 1/2 ips speed is available. The 3 3/4 ips speed is available for those cases where
the length of recording time of the tape is more critical than the actual quality of the recording.
21. MOBILE TAPE GUIDE
22. PINCH ROLLER
23. REWIND AND FAST FORWARD SWITCH
REWIND is possible with main selector (4) in any position other than "STOP", assuming pinch roller
lever (32) is in the fully open position.
FAST FORWARD is possible only with main function selector (4) in the "PLAYBACK– (with loudspeaker)
position and pinch roller lever (32) fully engaged.
The central position of this switch is "OFF" and this is the position that the switch should be in whenever the
machine is not required to spool. Keeping it in this position will prevent accidental spooling of the tape when
opening the pinch roller gate or playing back a recorded tape through the internal loudspeaker.
24. & 34. TAPE REELS
The 4.2 can be used with reels up to a maximum diameter of 5" (127 mm) with the plexi–glass lid closed, or up
to 7" (178 mm) with the lid open. However. it the QSET option is fitted to the machine the 7" (178 mm) reels
my be used with the lid closed.
If it is necessary to use reels of up to l0" (254 mm), then the QGB large reel adapter may be used.
25. & 33. TENSION ROLLERS
These two rollers keep the tape tension constant and ensure correct tape handling and positioning. During nor-
mal use neither of these two rollers should be at either end of its travel. If this is the case refer to the Mechanical
Calibration section of the service manual.
