Tips on recording level adjustment Setting the recording level too low will produce a hissing sound, while setting it too high will produce distortion. Generally, the proper recording level for high and low frequencies is lower than that for middle frequencies. When recording program sources with many high and low frequencies, set the level to a relatively low position, then make adjustments according to the recording results.

Cassette care Avoid touching the tape surface of a cassette to prevent contamination of the heads by dirt, dust, or oil on the skin. Keep cassettes away from equipment with magnets, such as speakers and amplifiers, as erasure or distortion on the recorded tape could occur. Do not expose cassettes to direct sunlight, extremely cold temperatures or moisture. Note on cassettes longer than 90 minutes We do not recommend the use of cassettes longer than 90 minutes except for long continuous playback.
Recording FM Broadcasts With the Dolby NR System
If your tuner does not have an MPX filter, or, if equipped, the filter is not working effectively, set the MPX FILTER button to ON (the FILTER indicator appears) when recording FM broadcasts with the Dolby NR system. The MPX filter eliminates remnants of the 19-kHz stereo carrier and 38-kHz subcarrier signals which may impair the operation of the Dolby NR system. Be sure to turn on the DOLBY NR switch since the MPX filter will not function otherwise.
Monitoring the Recorded Sound

As this unit has three separate heads for recording, playback and erasure, you can check the quality of a recorded sound by comparing it with the input source signal. To listen to the input source signal, press the MONITOR button to turn on the SOURCE indicator. To listen to the sound recorded on the tape, press the MONITOR button to turn on the TAPE indicator. Comparing the recorded sound with the sound source While recording, use this monitoring function to check that there is no distortion due to excessive level settings or sound degradation due to head contamination.

What Is the Dolby HX PRO System?
The Dolby HX PRO system provides precise bias control during recording to reduce distortion and improve linearity in the high-frequency range. The result is recorded sound that is highly faithful to the original. Since the HX PRO system operates only during recording, the same highquality sound is produced even during playback on other tape decks. The HX PRO system is independent from the Dolby NR system and is unaffected by the Dolby NR setting.

K615S-21 13-15

Calibrating the Bias Current and Recording Level
Although the ATS (Automatic Tape Selection) system in your unit sets the appropriate equalization characteristics and bias current for each tape type, you may be able to obtain even better results by doing the bias current and recording level calibration function described below.

BIAS REC LEVEL

Follow the procedure below to calibrate the bias current and recording level.
Adjusts the bias current within a range of about 20 %
Adjusts the recording level within a range of about 3 dB
Bias reduced () Output level in dB Bias increased (highfrequency response suppressed)

2 Press CALIBRATION.

Bias reduced (highfrequency response boosted)
Bias increased (+) Frequency in Hz
The peak level meters for adjusting the bias and recording level appear in the display window.
By changing the bias, you can tailor the response to your liking, for example by slightly emphasizing the upper or lower end. The frequency response of metal tape is much less affected by changes in the bias current than other tape types, and in some cases is uneffected. The adjustment range of this deck (about 20 %) may therefore not be wide enough to allow adjustment for all tapes. Recording level calibration Even when the recording level is adjusted correctly, a tape with low sensitivity will result in a low playback level. The REC LEVEL calibration control allows you to compensate for sensitivity differences among tapes to equalize both recording and playback levels. This is especially important when using the Dolby NR system, since the system is most effective when recording and playback levels are the same.

3 Press r , then P or to turn on the

recording test tones.

Playback level for an 8-kHz signal
Playback level for a 400-Hz signal
Notes You cannot monitor the sound during the calibration operation. It takes 2 to 3 seconds for the test tone level to stabilize.
Bias calibration Choosing the proper bias current for a tape ensures minimum distortion and flat frequency response. Lowering the bias current boosts high-frequency response, but also results in higher distortion. Raising the bias, on the other hand, reduces distortion, but also dampens high-frequency response. You thus obtain proper bias when the bias current and high-frequency response are well balanced.

Inserting a Blank Space During Recording Record Muting
The Record Muting function allows you to insert a foursecond blank between selections to enable proper MultiAMS operation (see page 8), or to replace unwanted recorded material with a blank of any length.
4 Adjust BIAS until both meters indicate

equal playback levels.

A high reading on the upper meter indicates a low bias current.
A low reading on the upper meter indicates a high bias current.

Locating a Specific Playback Position Memory Play
The Memory Play function allows you to use the counter to record a specific position on a cassette for fast relocation and automatic playback later.
Memorizing and Locating a Specific Playback Position
Press MEMORY to turn on the Memory Play function. Press RESET to reset the counter at the position to be memorized. The position is memorized.
While holding down , press 0 to return to the memorized position.
Returning to the memorized position while the unit is stopped Memory Stop
If you press only the 0 button when the MEMORY indicator is on and the unit is stopped, the tape rewinds and then stops when the counter reaches 0.00. Be sure that the unit is stopped before turning the Memory Stop function on, otherwise the Multi-AMS function will operate.
To turn off the Memory Play function
Press the MEMORY button, so that the MEMORY indicator disappears.

Note on Memory Play/Stop

The tape actually rewinds to slightly short of 0.00.
Do not turn off the power while using the counter
Turning the power off, then on again resets the counter to 0.00.
The Accuracy of the Linear Counter
Since the counter is not a digital clock, it will differ from the actual elapsed playback or recording time by a few minutes, depending on such factors as tape length and hub size.

Adjusting the Recording Level
The proper recording level, which differs according to the tape type, is indicated on the peak level meters for each tape type. Adjust the REC LEVEL control as high as possible without exceeding the recommended range for the inserted tape.
Peak level meter recording by tape type
Fig. A shows the recommended maximum peak level meter readings. a) for Type I or Type II tape b) for Type IV tape
Tips on recording level adjustment
Setting the recording level too low will produce a hissing sound, while setting it too high will produce distortion. Generally, the proper recording level for high and low frequencies is lower than that for middle frequencies. When recording program sources with many high and low frequencies, set the level to a relatively low position, then make adjustments according to the recording results.
Recording FM Broadcasts With the Dolby NR System
If your tuner does not have an MPX filter, or, if equipped, the filter is not working effectively, set the MPX FILTER button to ON (the FILTER indicator appears) when recording FM broadcasts with the Dolby NR system. The MPX filter eliminates remnants of the 19-kHz stereo carrier and 38-kHz subcarrier signals which may impair the operation of the Dolby NR system. Be sure to turn on the DOLBY NR switch since the MPX filter will not function otherwise.

While recording, use this monitoring function to check that there is no distortion due to excessive level settings or sound degradation due to head contamination.
What Is the Dolby HX PRO System?
The Dolby HX PRO system provides precise bias control during recording to reduce distortion and improve linearity in the high-frequency range. The result is recorded sound that is highly faithful to the original. Since the HX PRO system operates only during recording, the same highquality sound is produced even during playback on other tape decks. The HX PRO system is independent from the Dolby NR system and is unaffected by the Dolby NR setting.
