|DOLBY C NOISE REDUCTION SYSTEM]
mM The Dolby noise reduction system substantially reduces the tape background noise (hiss) in-
herent in the cassette medium. Dolby B NR is most widely in use. However, Dolby C NR is
a much more recent development and represents a significantly improvement over Dolby B NR.
M Tape background noise consists primarily of high fregnency information which is particularly
© annoying during soft passages. The Dolby NR system increases the level of low volume mid
and high frequency signals during recording and reduces the level of these signals by an identical
amount during playback. As a result, the playback signal is identical to the original source
- signal, but the level of background noise generated by the tape is greatly reduced.
E The operating principle of Dolby C NR is similar to that of B except for the encoding/decoding
response curves. The noise reduction effect obtained by Dolby C NR is up to 20dB, compared to
10dB with Dolby B NR. In addition, Dolby C NR uses an antisaturation network and spectral
skewing circuitry, and significantly improves the dynamic range in the mid to high frequencies.

| AUTO TAPE SELECT FEATURE |
This Stereo Cassette Deck contains an Auto Tape Select feature which automatically selects
the optimum bias and equalization for the tape in use. This is accomplished by detection of tape

1) Operation of the Tape Counter
(1) Press the RESET button to reset the counter to “0000”.
(2) By using the PLAY, FF, or REW functions, the reading of the counter will change to
indicate index position.
* During recording and playback operations, the counter is useful for noting the location
of existing programs or positions where recording is to be started.
* When the power switch is turned “off”, the counter display turns off. When the deck
is turned back “on”, the counter is automatically reset to “0000”. |
* The reading of this counter does not correspond with that of any other deck.
2) Operation of MEMORY STOP
(1) During recording or playback operations, MEMORY STOP can be used to locate a par-
ticular point on the tape. At the desired point, reset the counter to “0000”. With the
MEMORY STOP button in the “on” position, the deck will stop at the “ 0000” point
(actually between “9995” and “0000” during REWIND operations.
(2) The MEMORY STOP indication will light when this function is activated.
(3) Notes: e When the power is turned “off”, this function is automatically deactivated.
* The MEMORY STOP is accurate to —5 on the counter, and will stop between
“9995” and “0000”.
3) Display Functions
(1) The position of the tape in use is displayed automatically. NORMAL, CrOs, or METAL
indicators light in the display.
(2) Ifa blank space is to be made during recording, hold the PAUSE/MUTE key in. At this
| time, the PAUSE/MUTE indicator in the display will flash in one-second intervals.
(3) The display features two-color lettering and indications for easy identification.
| PROPER RECORDING LEVEL
A too high recording level can saturate the tape and cause distortion. On the other hand,
if recording levels are set too low, soft passages will be marked by residual noise. Proper
recording level is the single most important factor for making well balanced recordings.
— 12 —
MThe tape select indicators—NORMAL, CrO:, and METAL—provide guidelines for the maximum
allowable recording levels for each tape type. Adjust the INPUT LEVEL controls while checking
the FL PEAK METER.
Guideline for maximum recording level

on program sources or the type of tape used.

MMeter reading difference between L and R channels
The left and right channel readings of the FL PEAK METER can differ due to variations in
input signal levels. In such cases, adjust the individual channels of the INPUT LEVEL controls
until identical meter readings are obtained for both channels.
RECORDING BIAS ADJUSTMENT |
For best recording results, monitoring during the recording process and comparing various
recordings using your own judgement are essential.
The DR-M22 is equipped with a bias fine adjustment control to assist you in setting the
proper bias for different types and brands of recording tape. At the center-stop position,
the deck is set for a reference bias level for CrO. and NORMAL tapes. If the resulting
recording in this position has too much or too little high frequency content, varying the bias
fine adjustment control can be useful to achieve better results.
If the high frequencies (treble sounds) are to be boosted, turn the bias contro! counterclock-
wise to decrease bias current. If distortion is of more concern than high frequency response,
turn the control clockwise to increase bias current. By the use of this control, you can
record tapes with response that matches your personal listening tastes.

m Removing the cassette compartment cover
It will be more convenient if the cassette
compartment cover is removed during the
cleaning of the pinchroller and heads, or during
demagnetizing of heads. |
Follow these procedures:
1. Press the EJECT button to open the cassette
compartment.
2. Hold only the cover of the cassette com-
partment and pull it up. The compartment
cover is removed from the front. (Fig. 16)
3. Replace and lock the cassette compartment.
The heads and the pinchroller will be easily
accessible.
When attaching the cassette compartment
cover, reverse the above procedure.
a Head Cleaning
After long usage, tape coating or dust may
adhere to the heads causing deterioration of
sound. Clean them regularly. Use a cotton
swab moistened with cleaning solution (such
as alcohol). (Fig. 17)
Note :
1. Some cleaning cassettes on the market have
a strong abrasive effect and scratch the
heads. Use cotton swabs instead of cleaning
cassettes.
2. Since the use of metal tapes is apt to collect
more dust on the heads, clean the heads
more often to enjoy optimum sound.
m Cleaning the pinchroller
and the capstan
If the pinchroller or the capstan accumulate
dust, tape transport may become unstable
resulting from slippage during recording or
playback. The tape can also be damaged by
being rolled up around the capstan.
Clean them with a cotton swab or a soft
cloth moistened with cleaning solution (such
as alcohol). (Fig. 18)
m Demagnetizing the heads
The heads may become magnetized after long usage or by having a strongly magnetized object
brought near them. The result is a generation of noise, loss of the high frequency range, or
erasing the treble components of pre-recorded tapes and adding noise.
Demagnetize the heads on a regular basis.
E Procedure
1. Be sure to turn “off” the power supply.
2. Turn the demagnetizer “on” while it is more than 30cm away from the heads. Bring the
demagnetizer near the heads and slowly move it in a small circle four or five times.
3. Slowly move the demagnetizer away from the heads and turn “off” the power of the de-
magnetizer when it is about 30cm away from the heads.
