What is stereo?

There are now two system of high fidelity, monophonic (monaural) and stereophonic. Monophonic is a system that starts from one microphone and is fed through a single high fidelity set. Stereophonic is a double system. Two separate microphones are placed at different sides of the orchestra and two different systems are used to keep the two signals or channels separated. Two separate speakers are used, placed on different sides of you room. Stereo is much like 3-D photography, two slightly different sound reach your ears giving you a new dimension in sound.

Sherwood S-2400

 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.
