Teac A-3300S - Tape SPEED Selector Switch; Friction-Coupled Control Knobs.10; RECORD BIAS and EQ Switches

Tape SPEED Selector Switch
RECORD BIAS and EQ Switches
Control of the tape speed is provided for the two common
recording speeds: 7-1/2 ips (15 ips - 2T) and 3-3/4 ips
(7-1/2 ips - 2T). The slower speed will give you twice the
time from a reel of tape as the faster, but with a very slight
decrease in performance as indicated in the specifications.
The SPEED Selector provides the slower speed when
depressed to the (-*=*-) position. A second push releases it
back to the higher speed ( n).
Friction-coupled Control Knobs
The MIC, LINE and OUTPUT Level Controls are designed
with both channels on the same shaft. This pairing permits
simultaneous and parallel adjustment of both channels. By
grasping cither knob (Left or Right channel), you have con¬
trol over both channels, for these knobs are held together
by friction.
To change only one of the channels on a control, grasp the
inner (Left channel) knob with one hand and the outer
(Right channel) knob with the other hand. Hold one knob
stationary while you rotate the other.
Tape recording technology was recently challenged by the
improved tapes developed by recording tape manufacturers.
These tapes offered improved performance from tape decks*
but this better performance was only possible by changing
the internal electronic characteristics of the tape deck
The TEAC 3300S has special circuitry for these new low
noise/high output tapes as well as conventional circuitry for
the regular tapes. The proper circuitry is selected by the
RECORD - BIAS and EQ Switches.

BIAS Switching
The HIGH position is preferred for most of the low noise/
high output types of tapes. These tapes sell under a variety
ot different names, but can be recognized as an improved
or advanced type of tape. The NORMAL position is ideal
for conventional kinds of tape, which still give excellent
recording results with the TEAC 3300S
Some of the newer kinds of tape are designed for use with
the lower, NORMAL Bias levels. If you are in doubt as to
which level to use, experience, or your dealer can tell you
which to use.
EQ Switching
The EQ Switch controls equalization for recording. Like
the BIAS Switch, this has no effect during Playback opera¬
tion. Generally, you should place this switch in HIGH if the
BIAS Switch is in HIGH. These switches are set to match
the type of tape, HIGH for low noise/high output. NORMAL
for conventional tape. You may, through experimentation,
find a particular brand which gives better results using
HIGH Bias and NORMAL Equalization.
Some examples of these exceptions are given in the chart
on page 15.
