Do you have a question about the Teac W-850R and is the answer not in the manual?

Overview

  1. Function Description
  2. Usage Features
  3. Maintenance Features

The TEAC W-850R is a double auto-reverse cassette deck designed for recording and playback of audio cassettes. It features two cassette holders, TAPE I and TAPE II, allowing for various operations such as continuous playback, continuous recording, and high-speed dubbing between the two decks.

Function Description:

The W-850R supports both normal and high-speed dubbing, enabling users to copy an entire recorded section from a pre-recorded cassette in TAPE I to a recordable cassette in TAPE II. Normal speed dubbing performs the copy at the standard playback speed, while high-speed dubbing doubles the speed, significantly reducing the time required for copying. During dubbing, the recording levels for TAPE II are automatically set to match the signal levels from TAPE I, as indicated by the peak level meters.

The deck incorporates Dolby noise reduction and HX Pro headroom extension technologies, manufactured under license from Dolby Laboratories. These features are designed to improve sound quality by reducing tape hiss and expanding dynamic range during recording and playback. Users can select the appropriate Dolby NR system (OFF, B, or C) to match the recording or playback requirements.

A multi-counter display provides a conventional tape counter function, counting up during forward tape movement and down during rewind. This counter can be cleared to "0000" by pressing the COUNTER CLEAR button.

The W-850R also includes several convenience features to enhance the user experience. The INTRO CHECK facility allows for easy searching of specific tunes by fast-winding to the beginning of each tune, playing the first 15 seconds, and then fast-winding to the next. This cycle continues until a play button is pressed or the function is released. The BLANK SCAN facility helps skip long blank portions during playback by automatically entering fast-forward mode when a blank section of more than 10 seconds is detected, resuming playback at the next recorded section.

The Computomatic Program Search (CPS) function enables users to select and play any tune up to 20 tunes ahead or before the current one. This function relies on detecting blank spaces of at least 4 seconds between tunes, which can be created using the REC MUTE function. CPS will fast-wind the tape to locate the desired tune and then begin playback from its start.

For recording, the deck allows users to record from a stereo system or using a microphone plugged into the MIC jack on the front panel. The REC LEVEL control and BALANCE control provide adjustments for recording levels and input signal balance, respectively. The REC MUTE button facilitates the creation of blank spaces on the tape, useful for editing or for the CPS function. Pressing REC MUTE during recording will create a 4-second blank space and then automatically enter record-pause mode. Holding the button longer will create a longer blank space.

The SYNC REV (Reverse) button enables synchro reverse dubbing, allowing both decks to reverse simultaneously during dubbing. This is particularly useful for copying tapes of different lengths while maintaining the original content's exact timing.

CD Synchro Dubbing is a specialized feature that allows synchronized recording from a TEAC CD player equipped with a CD/DECK SYNC terminal. By connecting the deck to a compatible CD player with an optional cable, recording can start automatically approximately 1 second after the deck begins recording, ensuring seamless synchronization.

Usage Features:

The W-850R offers flexible tape travel modes, controlled by the REV MODE switch. These modes dictate how the tape behaves when it reaches the end, including single-side playback/recording, continuous playback/recording with automatic reversal to the other side, and continuous playback through multiple cycles (up to 5 for continuous playback).

Loading a cassette tape involves turning the cassette's hub to take up any slack, pressing the eject button to open the compartment, loading the tape with its open edge facing down, and gently closing the compartment door. It's important to note that the cassette holder cannot be opened during recording or playback.

For recording, users must ensure that the safety tabs on the cassette's spine are in place. If they have been broken off, the holes can be blocked with adhesive tape to enable recording. The deck automatically erases previously recorded material when a new recording is made. Alternatively, a tape can be erased by "recording" on it with the REC LEVEL control set to "0".

Manual editing during normal-speed dubbing is possible using the REC MUTE and PAUSE buttons on TAPE II. This allows users to selectively record desired tunes from TAPE I to TAPE II while skipping unwanted sections.

The remote control unit is not provided as an accessory with the W-850R. However, the W-850R mechanism (TAPE I/TAPE II) can be operated using the "UR" remote control unit provided with a TEAC receiver or amplifier.

Maintenance Features:

Regular maintenance is crucial for optimal performance of the W-850R. The heads and tape path should be cleaned and demagnetized periodically.

Cleaning Tape Path: This involves applying head cleaning fluid to a cotton bud or soft cloth and lightly rubbing the heads, capstan, and all metal parts in the tape path. The pinch roller should also be cleaned using rubber cleaning fluid. TEAC Tape Recorder Cleaning Kits (HC-2, RC-2, or TZ-261) are available for this purpose.

Demagnetizing Heads: With the power off, the heads should be demagnetized using a TEAC E-3 demagnetizer. Users should refer to the demagnetizer's instructions for proper usage.

The manual also provides troubleshooting tips for common issues such as no power (check power cord connection), no audio output (check connections), low sound quality (check for dirty/magnetized heads, tape quality, NR system selection), and inability to enter record mode (check record protection tabs or microphone connection).
