Fisher Studio-Standard CR-W50

The Fisher CR-W50 is a Studio-Standard Stereo Double Cassette Deck designed for high-fidelity audio recording and playback. It features two cassette decks, Deck 1 primarily for playback and Deck 2 for both recording and playback, offering versatile functionality including sequential playback and synchro dubbing.

Function Description:

The CR-W50 allows users to play back recorded cassettes on either Deck 1 or Deck 2. Deck 2 is capable of recording from various audio sources such as PHONO, TUNER, CD, or AUX inputs from an amplifier. A key feature is its synchro dubbing capability, enabling direct recording from Deck 1 to Deck 2, making it easy to duplicate cassettes. The deck also supports sequential playback, allowing continuous listening from one tape to another. An Auto Search Function (ASF) on Deck 1 helps locate program selections by detecting silent unrecorded spaces, facilitating navigation through recorded material. For recording, the deck includes INPUT LEVEL controls and indicators to help users set optimal recording levels, minimizing distortion and tape hiss. It also supports external audio timer operation for unattended recording or playback.

The inclusion of Dolby B and C Noise Reduction systems significantly improves the signal-to-noise ratio, especially with Dolby C, which offers up to 20 dB reduction, virtually eliminating tape noise and extending dynamic range. The wide frequency response across different tape types (Normal, CrO2, Metal) ensures faithful audio reproduction and recording.

Usage Features:

Dual Cassette Operation: The CR-W50 features two independent cassette decks. Deck 1 is primarily for playback, while Deck 2 handles both recording and playback.
Sequential Playback: Allows for continuous playback from one deck to the other, extending listening time without interruption.
Synchro Dubbing: Simplifies tape-to-tape copying from Deck 1 to Deck 2. When engaged, recording levels are automatically set, and Dolby NR circuits are automatically set to OFF to prevent over-processing during the dubbing process.
Auto Search Function (ASF) (Deck 1): Facilitates navigation by automatically locating silent spaces between program selections, allowing users to skip tracks or replay specific sections.
Auto Tape Select Mechanism (Deck 1): Automatically identifies the type of tape inserted (Normal, CrO2, Metal) and adjusts equalization for optimal playback.
Manual Tape Selector (Deck 2): Users manually select the tape type (Normal, CrO2, Metal) for proper recording bias and equalization.
Dolby NR (B and C-type): Switchable noise reduction systems to minimize tape hiss during recording and playback, enhancing audio clarity. Dolby C offers superior noise reduction compared to Dolby B.
Input Level Controls and Indicators (Deck 2): Independent left and right channel controls with LED meters allow precise adjustment of recording levels, crucial for high-quality recordings.
Pause Buttons: Temporarily stops tape movement during playback or recording, useful for preparing selections or taking short breaks.
Full Automatic Stop Systems: Both decks automatically stop tape movement at the end of a tape side, preventing unnecessary wear.
3-Digit Tape Counter (Deck 2): Provides a numerical reference for locating specific sections on a tape during recording or playback, with a RESET button to zero the counter.
Headphones Jack: Allows for private monitoring of recordings (Deck 2) and playback (Decks 1, 2).
Timer Operation: The deck can be set up for unattended recording or playback using an external audio timer.

Maintenance Features:

Head Cleaning: Regular cleaning of the heads, pinch rollers, and capstans is recommended to maintain high performance. This involves using a cotton swab moistened with isopropyl alcohol or special head-cleaning fluid to remove dust and oxide particles.
Cabinet Cleaning: The exterior surfaces can be cleaned with a soft, dry cloth or a cloth moistened with lukewarm water. Solvents, alcohol, or insecticides should be avoided to prevent damage to the finish.
Accidental Erasure Safeguard: Cassettes are equipped with tabs that can be broken out to prevent accidental recording over valuable material. Covering the opening with adhesive tape allows re-recording.
User-Serviceable Parts: The manual explicitly states "NO USER-SERVICEABLE PARTS INSIDE. REFER SERVICING TO QUALIFIED SERVICE PERSONNEL," indicating that internal repairs should only be performed by qualified technicians.
Warning against Mishandling: The warranty does not cover damage caused by mishandling or misuse, emphasizing the importance of following operating instructions.
Environmental Considerations: Users are advised to keep the unit away from direct sunlight, intense heat sources, dust, and humidity, and ensure adequate ventilation to prevent overheating.
Power Cord Handling: Instructions include not handling the power cord with wet hands and grasping the plug (not the cord) when disconnecting it from the AC outlet.
Liquid Spills: In case of accidental liquid spills, the power cord should be immediately unplugged, and the unit serviced by authorized personnel.

The Fisher CR-W50 is a robust and feature-rich double cassette deck, designed for both casual listening and serious audio recording, with a strong emphasis on sound quality and user convenience.
