Eyclusivc Scot: periectnnc. The world's most accurate and
reliable tuning device, obsoletes center-tuning meters by
employing a digital computer to automatically flash an indi-
cator panel light when best tuned for maximum reception . . .
(absolute center channel and lowest distortion).

Tm.» nm his! 'izleliv; r . t after years of costly experimentation.
SCOTT engineers discovered the answer underlying true AM
high-fidelity. Distortion so low that SCOTT AM is virtually
undistinguishable from FM! Employing latest PET and Inte-
gmted Circuit techniques in the 3300, they thoroughly elimi-
nated interference and drill. Weak stations now assume a
new clarity. strong stations become totally distortion-free. and
a new FET mixer improves cross modulation rejection and
cuts adjacent station interference

wrap" each wire around a terminal under tremendous torsion.
Consequently. the 3300 possesses a dependability akin to
aerospace and computer applications because the problems
of cold or unsoldered connections are drasticly reduced.

Tnc worlds first high iidelily IC Multiplex sectlon (no
larger overall than a cigarette filter) incorporates 31 tran-
sisters. 10 diodes and 29 resistors to ensure superior relia-
bility and superior FM stereo separation than conventional
printed circuit construction.

Scott's quartz crystal lattice tiller in the tuner lF section. never
requires realignment or adjustment. Never regardless oi
age or operating temperature! This revolutionary feature,
never found before in receivers in this price range. also yields
the extra dividend of very low distortion and incredible
selectivity.

F/C/O Circuitry provides close to distortion-free listening. even
at low volume levels The 3300 incorporates Full Comple-
mentary Output Transistors to achieve perfect undistorted
sound. over a wide power bandwidth at both 8 and 4 ohms...
a vital factor when connecting extra speakers. J

(ear becomes less sensitive to extremely low and high
notes than to those in the midrange. Thus. whenever the
system operates at a low volume level. the sound range
does not seem as wide as at higher levels. The Volume
Compensation automatically boosts extreme lows and
highs whenever the Loudness switch is set below 11
o'clock.

7. Tape monitor. To listen to recorded tape from an
external tape recorder, simply push this switch into the
MONITOR position. Immediately return the switch to
NORMAL when finished so other program sources may
be heard. it the tape recorder incorporates a separate
playback head (with playback pre-amplitier), it becomes
possible to check tape quality by listening to the record-
ing a fraction of a second after it is made. Pushing the
switch back and forth between NORMAL and MONITOR
permits you to hear whether the recording has a quality
equivalent to the source material being recorded.

8. Mode. Stereo: Engage this switch for all stereo
program material. Mono : Use this mode when a stereo-
phonic cartridge is used to play monophonic records. or
when a mono source is connected to one channel and
you wish to hear it through both speakers.

9. Muting. Eliminates annoying loud rushing or hissing
sounds audible between FM stations. With MUTING
OFF. an occasional weak station may be heard that
would otherwise be balanced out by the muting circuit.

10. Speaker 1 I speaker 2. These two switches
allow selection of the following speaker combinations:
1. SPKR<1 switch on: SPKR-2 switch off: SPKR-t speak-
ers only. 2. SPKR-1 switch on; SPKR-Z switch on: Both
sets of speakers. 3. SPKR-1 switch oft; SPKR-Z switch
on: SPKR-2 speakers only. 4. SPKR-i switch off; SPKR-2

switch off: Headphones only. \
(NOTE: Headphones may be used with the SPKR-1 and/
or SPKR-Z switches in either ON or OFF positions.)

11. Headphone iack. This low-level. low-impedance
output jack accepts a standard 3-conductor plug used
on most popular low-impedance stereo headphones.

Tuning knob, meter and indicator
lights

12. Tuning knob. A precisely balanced tuning knob
permits tuning ease across the entire illuminated tuning
dial.

13. Signal strength meter. Indicates strength of the
incoming FM signal and is most useful when rotating
an FM antenna or tuning AM stations. Meter readings
vary from station to station and from day to day. depend-
ing upon the amount of signal present and atmospheric
conditions.

14. Pertactune indicator "9'11. Incorporates a scan-
ning circuit connected to an automatic tuning indicator
light that goes on only when the Receiver is precisely
tuned to a broadcast.

15. FM stereo indicator light. A computer-like Auto-
Sensor automatically switches the Receiver to stereo
when tuned to a FM stereo broadcast. while simulta-
neously lighting the FM STEREO indicator light. If the
station returns to monophonic operation. the tuner auto-
matically switches the light and returns to monophonic
reception. To listen to a stereo broadcast, turn the Input
switch to FM and the Mode switch to STEREO.
