An automatic stop is provided to turn the take-up motor off aJter the tape has passed
through the transport to prevent damage to the tape.
Electro-Dynamic braking is used to provide instant braking without strain, stretching,
or breakage of tape.
All models using theT-300 Series Tape Transports are identical mechanically. The only
dilference is the head arrangement and preamplifier used.
The recording and playing time using 7 L/ 2 ips or 3 3/ 4 ips is as follows:
These recorders are to be connected to an outlet supplying ll? volts, 60 cyeles AC.

OPERATI NG
Threading the Tape
l. Depress the standby key.
2. Place a reel of tape on the supply spindle (2).
3. Place an empty reel on the take-up spindle (2).
4. Unwind approximately12 inches oftape from the
supply reel, hold asection taut and insert itinto
the head slot opening.
5. Insert the free end into one of the slots in the
take-up reel. Turn the take-up reel a few com-
plete revolutions to secure the tape to the reel
and to take all slack up between reels.
Playback
l. Connect the outputs of the preampliJier being
used to the inputs of an amplifier.
2. Depress the Standby key. It turns the AC power
on and opens the head assembly.
3. Place the Selector Switch or Switches in play
position.
4. Place a reel of tape on left-hand supply reel,
and thread the tape through the head slot opening
and between the capstan and pressure roller.
Place an empty reel of the same size on the
right-hand take-up reel and turn the reel in a
counterclockwise direction to fasten the tape to
the reel and to remove all slack between reels.
5. Switch the Head Selector Switch to 2-T for two
track tape and to 4-T for four track tape.
6. Placethe rubberreel retainerson thereel stand

ings, until the two meters are balanced. On
monaural recordings, adjust the volume control
to the desired listening level.
Recording
l. Connect the sound source to be recorded to the
proper input receptacles on the preamplifier.
2. Thread a blank tape onto the transport.
3. Depress the desired speed key.
4. Set the Head Selector Switch to 2-T on models
T-313 and T-323 and to 4-T on models T-333,
T-33?, and T-338. The four track models will
also record 2 track when used with blank or
bulk-erased tape.
5. Depress the interlock buttons, just to the left of
the record/ playback head, and move the levers
tothe rightto place thetransport in record oper-
ation.
