track in the left -to -right direction, automatically reverse,
record and replay the second track in the other direction.
It will start and stop on voice signals.
Master distribution amplifier complete with tape drive

8 watts. Total power output 10 watts. Complete with
master meter system measuring proper output signal
being fed into student positions. Sufficient capacity to
handle up to 200 student positions. Separate bass and
treble controls. Three position selector switch permitting
instant flipover from tape to living voice (microphone)
or to external source (phonograph, shortwave radio,

the cuullotap.e C -Slot Reel,
NOW BETTER THAN EVER I
The popular C -Slot reel -the fastest, easiest -threading reel ever developed-has
been structurally redesigned. It's now stronger than ever and even more convenient than before.

Since the revolutionary reel design was introduced about a year ago, engineers
have carefully checked service experience on all types of machines under all
operating conditions. This study pointed the way to still further improvements.
2. Drop tape in
Now, a slimmer, smoother tape slot gives a virtually unbroken hub surface for
inch

projecting beyond the hub
smoother winding under even the highest tape tension. A reinforced beveled edge
guides the tape more easily into the C -slot. Inside the hub, extra "ribs" have been
added and the bondirg area has been increased by 50%, making the entire structure practically indestructible.

No other reel can approach the C -slot for fast, easy threading. And the new, improved design is now standard for all 5" and 7" reels of Audiotape-an extra -value
feature at no extra cost! Another important reason why it pays to specify Audio tape for every recordirg need.
