Frequently Asked Questions - TCKB820S SONY

How do I clean the heads of my Sony TC-KB820S cassette deck?
Clean the heads, pinch roller, and capstan with a cotton swab lightly moistened with alcohol or tape deck cleaning fluid. Perform this cleaning every 10 hours of operation to prevent sound loss or excessive wow and flutter.
Why doesn't playback start?
Check that the cassette is inserted correctly and the compartment is fully closed. Ensure the record-protect tab is not broken. If the tape is loose, tighten it. Clean the heads if necessary.
How do I use the Multi-AMS function to locate a track?
During playback, press (as many times as the number of tracks to skip) to go to the next track, or press ◀◀ to go back. The function detects blank spaces of at least 4 seconds between tracks.
How do I perform auto calibration?
Insert a blank cassette. Press AUTO CAL until 'CAL' appears, then press ■ PAUSE to start calibration. The deck records test tones, reads them back, and automatically adjusts bias current and recording level.
What types of cassettes can I use?
The deck accepts type I (normal), II (chrome), and IV (metal) cassettes. The type is detected automatically (ATS) and the equalization and bias settings are adjusted accordingly.
How do I activate Dolby noise reduction?
Turn the DOLBY NR switch to the desired position: B, C, or S. For recording FM broadcasts, use the positions with MPX FILTER to improve Dolby effectiveness.
What should I do if the tape stops before rewinding is complete?
The tape may be loose: tighten it manually. If the 'M' indicator is displayed, press MEMORY several times to turn it off. The cassette case may also be warped; use another one.

text_image [2] [1] [1] [2] Previous track Current track Next track

Notes

  • The Multi-AMS function may not work correctly if:
    — the blank space between tracks is less than 4 seconds long.
    — the signal strength of the left and right channels are very different.
    — there is a passage of low frequencies or very low volume within a track.
  • Since the counter is not a digital clock, it will differ from the actual elapsed playback or recording time.

Adjusting Bias and Recording Level Calibration Automatically

Since there are many different types of cassettes on the market, your tape deck automatically sets the appropriate equalization characteristics and bias current for each tape type (ATS: Automatic Tape Selection). However, you can get better recording results by doing the automatic bias current and the recording level calibration.

SONY TCKB820S - Adjusting Bias and Recording Level Calibration Automatically - 1

text_image SONY AUTO CAL ■■ PAUSE

1 Insert the cassette you want to record on. Make sure the record-protect tabs on the cassette have not been removed.
2 Press AUTO CAL until "CAL" appears in the display.

Note

If the record-protect tab for that size has been removed (see page 11), "AUTO CAL" in the display flashes three times and automatic calibration cannot be performed.

3 Press II PAUSE to start the automatic calibration procedure.

The automatic calibration procedure starts (i.e., recording test tones, rewinding, and playing back).

During the calibration, the counter changes from 9 to 0.

SONY TCKB820S - Note - 1

text_image AUTO CAL BEC CA L9

When the automatic calibration procedure ends, the tape rewinds to the original position, the counter returns to normal and the tape deck stops.

4 Start the actual recording (see page 6).

To cancel the automatic calibration function

Press ■.

If "AUTO CAL" flashes continuously

The automatic calibration procedure has been interrupted by:

— The end of the tape. Turn the cassette over or rewind the tape to a new position that allows recording of the test tone.
— Damaged tape or dirty heads. Change the cassette or clean and demagnetize the heads (see page 11).

Updating the calibration setting

As long as the tape deck stays on, calibration data are saved and called up each time you insert a cassette of the same type (I, II or IV). "AUTO CAL" appears in the display when you insert a cassette to indicate that calibration data for that tape type exists. However, we recommend that you repeat the automatic calibraion procedure each time you insert a new cassette since cassettes of the same type also vary in their characteristics. Before recalibrating, be sure to clear the existing calibration data by pressing AUTO CAL until "AUTO CAL" disappears from the display. Then start from Step 2 of the automatic calibration procedure.

Inserting a Blank Space During Recording (Record Muting)

You can insert a blank space of 4 seconds between each track. The blank spaces between tracks let you locate the track easily with the Multi-AMS function (see page 8). Also, use this function to eliminate only unwanted portions on the tape.

Precautions

On safety

  • Do not disassemble the cabinet — this may result in an electrical shock. Refer servicing to qualified personnel only.
  • Should any solid object or liquid fall into the cabinet, unplug the tape deck and have it checked by qualified personnel before operating it any further.

On power sources

  • Before operating the tape deck, check that the operating voltage of the tape deck is identical with your local power supply. The operating voltage is indicated on the nameplate at the rear of the tape deck.
  • If you are not going to use the tape deck for a long time, be sure to disconnect the tape deck from the wall outlet. To disconnect the AC power cord (mains lead), grasp the plug itself; never pull the cord.
  • AC power cord must be changed only at the qualified service shop.
  • The unit is not disconnected from the AC power source (mains) as long as it is connected to the wall outlet, even if the unit itself has been turned off.

On operation

  • Because of a safety mechanism, the function buttons will not operate if the cassette holder is not completely closed, if there is no cassette in the cassette holder, or if a cassette has been incorrectly inserted into the cassette holder.
  • Be sure to stop the tape before turning off the tape deck. Otherwise, the tape may be damaged.

On placement

  • Place the tape deck in a location with adequate ventilation to prevent heat build-up in the tape deck.
  • Do not place the tape deck:
    — on a soft surface such as a rug that might block the ventilation holes on the bottom.
    — in a location near heat sources.
    — in a place subject to direct sunlight.
    — in an inclined position.
    — in a place subject to excessive dust or mechanical shock.

On cleaning the tape deck

Clean the cabinet, panel and controls with a soft cloth slightly moistened with a mild detergent solution. Do not use any type of abrasive pad, scouring powder or solvent such as alcohol or benzine.

If you have any questions or problems concerning your tape deck, please consult your nearest Sony dealer.

Glossary

ATS

Automatic Tape Selection. The tape deck automatically sets the appropriate equalization characteristics and bias current according to the tape type inserted in the deck.

Automatic calibration

The automatic adjustment of the bias current and recording level for the inserted tape.

This adjustment works together with the deck's ATS

(Automatic Tape Selection, see above) to get the best possible recording results on any tape.

Dolby HX PRO system

Distortion and noise reduction system. The Dolby HX PRO system reduces distortion and noise in high-frequency response while recording. A tape recorded with this system brings the same high-quality sound even when you play the tape on the other tape decks.

Dolby NR (noise reduction) system

Noise reduction system for eliminating hissing noise. The Dolby NR system boosts the low-level signals in high frequency during recording and restores them during playback.

There are 4 types in the Dolby NR system: A, B, C and S.

A-type is for professional use (not available on this tape deck), and B, C and S-types are for consumer use. S-type has the maximum noise reduction capability, followed by C and B.

SONY TCKB820S - Dolby NR (noise reduction) system - 1

MPX filter

Multiplex filter. A filter for eliminating the 19-kHz stereo carrier and the 38-kHz sub-carrier signals that may impair the Dolby NR system. Usually the tuner has an MPX filter. If you cannot get a satisfying result when recording FM broadcasts with Dolby NR system, your tuner does not have a filter or the filter is not working. In this case, turn the DOLBY NR switch counterclockwise to the position you want — B, C, or S with MPX FILTER.

Multi-AMS

Multi-Automatic Music Sensor is a function that locates the beginning of up to 30 tracks before or after the current track by detecting a blank space (of over 4 seconds) between tracks.

Tape counter

A four-digit readout for monitoring elapsed playing or recording time. Useful for editing tapes. Press RESET to zero the counter (00 00).

Test tones

10-kHz and 400-Hz signals produced by the tape deck when you do the automatic calibration.
