'Ihc Il hcr 400

65-Walt FM-Stereo Receiver

The Fisher 400 has long been liavorcd by the new-
comer and hi-fi enthu" alike. who preier an
instrument with substan a] power at an unusually
modest cost. It embodies the best in electrical wiring
workmanship and audio engineering. and its rugged
tube circuitry afiords virtually unlimited years of
trouble-free service.

There has been no compromise in the e'ssential
design characteristics. or in the rigorous test proce-
dures and standards of the 400 since its introduction.
Circuit improvements and refinements have, of
course, been made continuously. The gradual up-
grading oi an already fine instrument. coupled with
a substantial reduction in manufacturing costs. has
resulted in reproducing equipment of outstanding
value for the economy-minded mu love

The Fisher 400 incorporates a high-sensi tvity FM-
Stereo tuner. a flexible stereo preamplifier. and a
65-watt (IHF) stereo power amplifier. The front-end
section employs three tuned circuits for increased
selectivity. thus permitting the user to tune in a far
greater number of FM stations than he might expect
with ordinary FM equipment. To heighten the sensi-
tivity of the instrument so that even the weakest IM
signal is brought in enjoyably. Fisher engineers have
included four wide-band 1F stages. and three stages
of limiting. The ratio detector. utilizing a matched
pair of germanium diodes for linear performance
over an extremely wide range. is capable of detecting
and transmitting the most complex stereo-multiplex
signals and reproducing them without distortion.

The multiplex demodulator features the superior
timedivision method. This System. bcst for producing
maximum stereo separation. is one of several circuit
designs Fisher engineers have incorporated in this

model. Another is STEREO BEAM. the Fisher trade-
mark that signifies the Fisher 400 has the com-eu-
ience feature of automatically signaling the presence
of a stereo broadcast. It is also used as a tuning indi-
cator for microaceurate tuning of mono and stereo
broadca.

The audio control center of the 400 has all the
desired features. including tone and balance controls.
loudness compensationa sharp-cutofl high frequency
filter. and a speaker on-ofi switch. In addition. the
exclusive Fisher Direct Tape Mani/0r has been in-
corporated to provide monitoring of tape recordings.
followed by immediate playback. with unrestricted
use of all audio controls.

The Mode/Program Selector has seven positions
(Tape Head. lzltono Mono. Phono Stereo. FM Stereo.
FM Stereo Filter. FM Motto. Aux-Tape) to aflord
easy access to any program source. Other extras
include a center-channel output (for a separate power
amplifier]. choice of NORMAL or LOCAL antenna in-
puts to prevent overloading on strong local signals.
and DC on all filaments of thc lovt-level audio stages
to reduce hurt) and noise to thc vanishing point.

Although the 400 would appear to be ideal for
those with a very limited budget. many audio cntltu-

needs. It epitomizes the wry best qualitics of Fisher
engineering-crccptiona| performance. brcadth of
flexibility. ease of operation. and an abundance of
power. capable of driving several pairs of speaker
