Sherwood CDP-100 cd player

The compact disc just may be the most heart-stopping concept in sound since stereo. But the most heart-stopping feature of compact disc players has been their price. Now, with Sherwood's CDP-100, you can relax about money and really get excited about sound.

A tradition of affordable excellence.

Sherwood is well-known for high-quality audio products at affordable prices. And our new CD player is no exception. While others were still on first generation models, we combined advanced second-generation performance with a no-nonsense array of useful features. And we did it in a way that not only makes sense, but saves you dollars as well.

Three laser beams for better tracking.

Most CD players use only one laser beam. Sherwood put a three-beam laser into the CDP-100, because a three-beam system virtually eliminates distortion caused by spurious data from adjacent tracks.

Two filters, not one.

All CD's require filters, because the decoding of digital sound generates a sampling frequency which must be filtered out, or distortion will be heard.

Other CD players use one way steep analog filter; this can cause phase distortion. Sherwood's answer is to use a digital filter to double the sampling frequency, then use a more gentle type of analog filter for reduced phase distortion. The result; better sound at less cost.

Easy-to-use functional controls

Inserting a disc is easy, thanks to a "smart" motorized drawer under microprocessor operation. It even knows if you accidentally put the disc in upside down.

You can easily access any selection, and there's a two-speed fast forward and backward, so you can listen while you quickly locate the spot you want to bear. You can even set the CDP-100 to repeat the entire disc for continuous music.

 

 

Sherwood S-3000 tuner

FM Tuner

The 5-3000 has been styled and designed primarily as an operating mate for the Sherwood Model 5-1000 amplifier, however it has operating flexibility which will work effectively with practically any good high-fidelity amplifier system.

The Model 5-3000 tuner can be used either in its self-contained metal cabinet (for open-shelf or table-top mounting) or the cabinet can be removed and the tuner built into your custom cabinetry. Refer to section under "Custom-Panel Installation" for further details.

Sherwood S-5000

 The "new" Sherwood S-5000 dual amplifier preamplifier makes possible either stereo or monaural high-fidelity systemoperation with only one set of basic coordinated controls, yet offers every important control feature essential to both stereo and monaural operation. These include 10 two-channel controls, stereo normel/revers switch, phase inversion switch, and dual amplifier monaural operation with either set of input sources. The five modes of operation; stereo, stereo-reversed, monaural 1, monaural 2, monaural 1 + 2, are selected by the function switch which also operates a corresponding group of indicator lites to identify the selected operating mode.

All controls operate both channels simultaneously. In addition, the bass and treble controls feature friction-locked shafts which also allow the adjustment of one channel separately from the vertical rumble and noise components balanced out. A tape monitor switch permits instant comparison of recording input signal to tape with recorded output from tape when used with recorders offering monitor heads.

 Special features:

Stereo-monaural indicator lights

Dual/single bass and treble control

Compensated ganged loudness control

Plays monaural records with vertical rumble and noise balanced out

Stereo normal/reverse switch

Phase inversion switch

Ganged presence rise switch

Ganged phono and scratch filter switches

Ganged tape monitor switch

Stereo balance controls both channel

Six high level inputs

Four phono/tape preamp inputs

3rd channel output

Two tape monitor inputs and recording outputs

Speaker damping factor selection

Color coded cables and receplacles

 The Model S-5000 also can be used as a 40 watt monophonic "starter" system planned for later conversion to a 20 + 20 watt stereophonic system. The interchange from a 40 watt single amplifier to a 20 + 20 watt dual amplifier is accomplished by a single front panel switch. This circuit connection features the full sum of the 2 separate amplifierrs' outputs instend of using the power-robbing parallel connection commonly used.

All Sherwood amplifier now provide selectable damping factors of 10/1 (normal) or 2/1 (for use with today's popular compact speaker systems).

 The Sherwood S-5000 Function Selector operates its associateed indicator lites to identify the source-speaker combination selected. This exclusive feature, which also serves as the off-on pilot lite, tells at a glance which stereo or nonaural function has been selected as shown in the chart at right. Note especially the last position, :Mono S1 & 2" which connects a stereo phono pickup in such a manner that the vertical rumble and scratch components are balanced out for use with monaural records.

Important aids to flexibility of stereo system operation are the bass and treble controls included in the Model S-5000. each control features friction locked dual knobs. With normal usage, the main knob on each control operates both left and right hand channels  simultaneously due to its friction-locked concentric shafts. In addition, one channels tone may also be adjusted independently of the other. This is possible, because the 2nd-channel indicaqtor knob can also readily be adjusted without moving the 1st-channel knob as permitted by the friction -locked shafts. Afyer this independent adjustment, both channels  are again automatically ganged together for simultaneous operation by the main knob without upsetting the inter-channel relationship selected.

Sherwood S-8000

 With every performance capability of a separate tuner and amplifier, Sherwood's "new" S-8000 FM Stereo Multiplex Receiver is rapidly becoming one of the industry's most popular high-fidelity components.

This unit contains all of the electronics for a complete home music system on a single compact chassis. The S-8000 features two 32-watt amplifiers, complete with dual preamplifiers for phono and tape plus a highly sensitive FM tuner with complete wired-in circuitry for receiving FCC-approved FM multiplexed stereocasts. Just add speakers to complete your stereo home hi-fi music system.

  

The Model S-8000 integrates in one unit all of the important controls and perormance features offered separately on any of Sherwood's FM tuners, stereo amplifiers, and FM multiplex adapters. The usual concern about heat dissipation from a complex unit of this type has been solved by Sherwood design engineers. In the S-8000, the unique new Novar output tubes have been tilted toward the rear of the chassis so that tube heat is deflected away from other components by Sherwood's exclusive air-cooled heat baffle.

Sherwood S-8800a

 First of a new breed  - from Sherwood.

This is what high performance is all about. A bold and beautiful new FM Stereo receiver bred to leave the others behind. 160 crisp, cleanwatts-power in reserve. Up-front, ultra-now circuitry featuring Field-Effect Transistors and microcircuitry. Front-panel, push-button command of main, remot, or mono extension speakers and loudness contour. Sherwood high-fidelity - where the action is - long on reliability with a three-year warranty.

 Sherwood presents its latest version of the world-famed S-8800 series All-Silicon solid-state receivers. Six push buttons control the choice of main or remote stereo speakers (or both simultaneously), loudness contour, stereo/mono selection, tape monitoring, and high filter.

Unique with this receiver are two front-panel jacks, one to operate stereo headphones and another to playback or record into a tape recorder (or cassette recorder). The tape jack can also be used in conjunction with the S-8800a rear-panel jacks for dubbing from one recorder to another or for simultaneous recording on 2 recorders.

 New features such as these are backed up by the latest engineering advances such as Microcircuitry in IF and Synchro-phase FM limiter/detector circuits (providing -60 dB AnM rejection and 2.0 dB capture ratio). Also featured are Field Effect transistors in RF and Mixer stages (enabling -95 dB cross-modulation rejection).

A power reserve of 160 watts (4 Ω music power) is available to operate 2 sets of stereo speaker outputs and also a mono speaker output on the rear panel. Superlative sound reproduction is provided by the Sherwood S-8800a FM rated at less than 0,15% distortion and stereo amplifier rated at 0,1% at normal listening levels.

All of Sherwood's solid-state receivers, which have long been acclaimed throughout the world for their reliability, now offer a full 3-year warranty on all parts.
