Sherwood
Model S-2400 Solid State AM/FM Stereo Tuner
For those
who prefer the versatility of separate components, Sherwood offers the S-2400
AM/FM stereo tuner, which incorporates every advanced circuit design and
component device known to be reliable. Performance specifications are
unequalled in its price range; the features offer outstanding flexibility and
ease of operations; and the styling speaks for itself (the walnut case is
included at no extra charge).
Design
Features
1,8 µV FM
sensitivity (IHF). Four gang variable tuning capacitor. Junction type FET's in
primary and secondary RF stages - image rejection is better than 90 dB.
Sherwood's new solid state ceramic FM IF filtering circuit provides superior
selectivity and stability and lower FM distortion.
Control
Features
Two meters
provide tuning for absolute center channel and maximum signal strength,
indicator lights for AM, FM and FM Stereo. Linear dial for ease in channel
location. Balanced flywheel for velvet action tuning. Separate power off/on
switch. "Stereo only" switch permits listening only to stereo
stations - monophonic stations are muted. Selector switch for choice of AM, FM,
Mono or FM Stereo. Variable output volume control to control or match tuner
putput to the amplifier. FM muting to eliminate unpleasant noise while tuning
between stations. Multiplex noise
cancellor to reduce high frequency multiplex noise. Rear outputs for
oscilliscope.
Four Channel
Feature
"Four
channel" FM output jack on rear panel permits four channel reception (with
use of a special demodulator) when the FCC approves a method of broadcasting
four discrete channels.
