GENERAL INFORMATION
The Fujiya Corder Model EX-3ll records and plays back two tracks of material on
standard-width recording tape. This doubles the recording and playing time without loss of
quality orfrequency response. Recordings canbe made from a phonograph, radio, or television
receiver, in addition to those made directly from the microphone.
A record safetylock prevents accidental erasure, and aQuick Stop controlpermits pauses
to be made during a recording.
Model EX-3ll has one tape speed, 3 3/ 4 ips. The playing and recording time is 90
minutes for a 900-foot reel of tape.
Model EX-3ll operates on 60 cycles, Il0-I20 volts AC only. Be absolutely certain it
agrees with these specifications before connecting to a supply line.

To Record From a Television Receiver
Use one of the three methods described under
"To Record From a Radio".
Dual Track Recording
These recorders record and play back on one-
half the tape width at a tlme, thereby resulting in
two-track recording. To record on the other half of
the tape, remove the full reel from the takeup reel
cup (1), turn the reelover and place it ontfie feed reel
cup (l). The tape can be stopped and the reels turned
over at any point during recording or playback.
