The Bass control increases the amount ot bass tones (such as
those of a tuba or bass viol) that you hear. With the Bass control
in the mid-position (marked NORMAL), the bass tones will sound
exactly as they did when they were recorded or picked up tor
broadcast. If you wish to emphasize the bass, simply turn the Bass
control clockwise. To decrease the prominence of the bass tones,
turn the Bass control counterclockwise.

The Treble control adjusts the intensity of the treble tones (such
as the highest notes of the violin or piccolo) that you hear. As with
the Bass control, the mid-position (marked NORMAL) will result
in the reproduction of treble tones exactly as they appear in the
program source. The relative strength of the treble tones (with
respect to the rest of the program material) can be increased by
rotating the Treble control clockwise. Turning the control counter-
clockwise decreases the relative amount of treble tones.

NOTE: The tone control settings have no effect upon recordings
made from the console through the recorder output jacks.

Automatic Shut-Off Switch

The Automatic Shut-Oil switch is used only when the Selector
switch is in the PHONO MONO or PHONO STEREO position. In
the OFF position, the Tuner and Amplifier portions of the console
are turned oft and on solely by the power switch on the Volume
control. mentioned above. The Automatic Turntable will turn ltsell
otf alter the last record has played, but the rest of the set will
remain on. In the ON position, the automatic switch in the Turn-
table will also control power to the Tuner and Amplifier. Thus,
after the last record has been played, the entire set will shut off
automatically. The set will be turned on again the next time you
use the Turntable, but If you do not plan to play records when the
unit is next turned on, be sure to turn the Automatic Shulolf
switch to OFF Otherwise, the entire set will be inoperative.

Speakers Switch
The Speakers switch has four positions: OFF, MAIN, REMOTE,
and MAIN + REMOTE. When the Speakers switch is set to OFF,

all speakers associated with the console (main and remote) are
disabled, enabling the listener to utilize the privacy ot headphone
listening. When the switch is In the MAIN position, only the built-in
left and right speaker systems operate. In the REMOTE position,
only speakers which have been attached to the EXTERNAL SPKR
terminals on the amplifier chassis will function. (See the section
entitled ACCESSORIES tor information about additional speakers,
which may be added for increased stereo separation or to provide
stereo in another room.) When the switch is turned to MAIN +
REMOTE, the built-in and additional speakers play simultaneously.

ACCESSORIES

General

Your set is provided with jacks and terminals for connecting
additional high fidelity components; a tape player or tape
recorder, for playback and recording of either mono or stereo
tapes; an additional high-level stereophonic or monophonic
source (if the two AUX jacks are tied together electrically). The
FISHER K-10 SPACEXFANDERG reverberation amplifier; a pair at
FISHER WS-1 Wide Surround® speakers; and external, remote
speakers for stereo elsewhere in your home can all be quickly
and easily connected to the radio-phonograph.

These connection points are all accessible trom the back of the
unit. You will find it helpful to refer to Figures 1 through 4
while you read what follows.

Tape Player or Recorder

On the Tuner-Control Chassis, there are two jacks marked TAPE
INPUT. These are high-impedance, high-level inputs, one for each
channel (left and right.) Into them you can feed a signal from any
tape recorder or playback machine as long as it already contains
the necessary preamplifiers and equalization. If you are In doubt.
consult your recorder's instruction manual.

nique, resulting in better separation than available with other
methods, less noise, and greater long~term stability.

The unique STEREO BEACON indicates by means of a light when
a multiplex FM stereo program is being broadcast, and auto
matically switches to multiplex and audio circuits to stereophonic
operation when set to the FM STEREO positions.

Turning to the AM portion of the tuner, we find a tuned RF ampli-
fier stage (EFQS/GBAS), which gives the tuner a sensitivity and
selectivity far above that of most conventional AM radios. Con-
version to the 455 kc lF is accomplished in the oscillator-mixer
stage, which employs an EK90/GBE6.

in the Control portion of the Tuner-Control chassis we find the
preamplifier and switching center oi the unit. Here are the
Tone controls. providing 17 db total variation of bass and treble;
the Volume and Balance controls; and the Selector switch, which
selects any one of eight possible program sources or modes of
operation. A pair of dual-triode preamplifiers (ECCS3/12AX7), one
for each channel, Supply the gain and RIAA equalization needed
for the magnetic phonograph cartridge. Equalization is accom-
plished by frequency-selective feedback, resulting in reduced

15

noise and distortion combined with accurate playback charac-
teristics. Output jacks are provided for feeding a tape recorder
with a signal unallected by Tone or Volume control settings.

The Power Amplifier chassis, located in the rear oi the set.
contains the DC power supply, which provides operating voltages
for the tubes on both the Amplifier and Tuner-Control chassis, as
well as for the transistors on the Amplifier chassis. There are
actually two distinct amplifiers here, each channel being amplilied
independently by a separate power amplifier. The power amplifiers
provide superior power bandwidth (output power at extremely
high and low frequencies) and improved transient response, due
to the lack of output transformers. Each amplifier consists of a
two-stage vacuum tube voltage-amplifier-driver circuit, feeding
two transistors in a single-ended push-pull configuration. The
power amplifiers provide 50 watts, both channels (IHF Music
Power Standards). Each amplitier is double-fused to prevent over-
loading of its output stage and destruction of the transistors by
accidental shorts, and to protect the speaker from the possibility
of DC overload due to shorted transistors. Feedback is obtained
directly from the hot side of the load in the output stage, and fed
back to the cathode of the voltage amplilier.
