Special Features

1. Master Fader Control
This feature permits smooth and easy fades during recording simply by pressing a button. Fade-in is performed by depressing the "Up D " side of the master fader control (251, and fade-out is performed by depressing the "Down 4 " side. You can choose between two fading speeds: Depressing the button strongly (two clicking sounds of the switch) and keeping it depressed causes the fading process to be performed in about 2 seconds. Depressing the button lightly (one clicking sound of the switch) or releasing the button after one push causes the fading process to be performed in about 6 seconds. The respective fading mode is indicated by the relative brightness of the indicators (24). In ordinary music recording, slow-speed fading may be more desirable, while highspeed fading can be used effectively for example to eliminate noise when the cartridge is lowered onto a record, etc.

2. Auto Play Feature

This feature is operated by means of the rewind button ( 5 ) or fast-forward button (9) and the record button (10). "Auto Play" means that the tape is stopped from rewind or fastforward at the counter indication " and the deck automatically starts playback from this point.
-0peration(1) Press the counter reset button (28) at the beginning of a recording or playback to return the counter indication to "0000". (2) After recording or playback is completed, lighting up the press the rewind button (51, indicator above the button. and then-while keeping the rewind button depressedpress the record button (10). The tape will now be rewound to the "0000" indication and playback will automatically start from there. The auto play feature can also be activated while the deck is already in the rewind mode: just press the rewind button once again and then press the record button. The above description is an example for the rewind mode, but the auto play feature can be operated in the same way in the fast-forward mode also.

5. MPX Alter

In the transmission of FM stereo broadcasts, a 19 kHz multiplex carrier signal is used. When recording from FM stereo broadcasts while using the Dolby noise reduction system, possible residues of this 19 kHz signal can cause malfunction of the noise reduction circuitry. To prevent this, the MPX filter cuts off any remaining carrier signal. Therefore. when recording from FM stereo broadcasts, set the MPX filter switch (18)to "On". The switch should be "Off" when recording anything else than FM stereo broadcasts.
(4) Set the On/Off button (left button) of the timer switch (16) to "On" and the Rec/Play button (right button) of the timer switch to the desired position ("Rec" for unattended recording, "Play" for timer playback).

Matching the Cassette Deck to Various Cassette Tapes
There are many brands of cassette tapes, which can be generally classified into three types: normal tapes (ferric-oxide formulations), chrome-equivalent tapes, and metal tapes. When recording such tapes with this deck, the tape selector switch (1 1) and the Eq switch ( 1 3) must be set according to the chart below. In order to fully realize this deck's potential, you should use tapes from the list below, whenever ~ o s s i b l e.

Tape Selector Switch

This swltch serves to select the appropriate bias amount and record equalization for different tape types. If bias current IS too low. high-frequency response rises but distortion also increases. If it is too high, high-frequency response as well as distortion decline. This deck's tape selector switch provides three positions: EX (normal tapes) SX (chromeequivalent tapes) and ZX (metal tapes). According to the tape used, the correct position must be selected. The position of thls switch is relevant only in recording and has no effect during playback.

Eq Switch

In order to match the deck to the characteristics of the tape, besides b ~ a s is it necessary to select the correct equallzatlon for recording and playback. This deck provides two Eq switch positions: "70 p s " and " 120 gs". Metal tapes (ZX) and chromeequivalent tapes (SX) are to be used with "70 p s " and normal tapes (EX) with "p s " This switch must be set to the correct position in recording as well as in playback

Bias Tune Control

This deck provides a bias tune control (121, which permits fine adjustment of the bias current after the standard values have been set by means of the tape selector switch (1 1). When using tapes recommended by this manufacturer (see list in preceding paragraph), the bias tune control should be left in the center click-stop position.
2. If the recorded signal sounds duller (has less highs) than the original source, turn the bias tune control to the left (counterclockwise).

Bias Tune

Note: - This deck is factory-adjusted to give best results with Nakamichi EX 1. SX and ZX 1 cassette tapes. - If tapes of inferior quality are used, the output in the high frequency range may not increase even if the bias current is lowered (the bias tune control is turned to the left); rather distortion only will increase.

Normal

3. By repeatedly performing steps 1. and 2., if necessary, minimize the difference in sound quality between the source signal ("Source") and the recorded signal ("Tape"). When using other tapes, the bias tune control should be adjusted as follows. The discrete 3-head configuration permits bias adjustment while instantly monitoring the recorded signal. 1. Compare the source signal ("Source") with the recorded signal ("Tape"). If the recorded signal sounds brighter (has more highs) than the original source, turn the bias tune control to the right (clockwise).
When wishing to perform an absolutely accurate adjustment of bias, the prescribed procedure is as follows. 1. Set the Dolby NR switch to "Off". 2. Use a test tone oscillator, the Nakamichi T-100 Audio Analyzer, or a similar device. 3. Connect the oscillator output to the input terminals on the rear panel of the cassette deck. 4. Record test signals of 1 kHz and 15 kHz on the tape at a - 20 dB level. 5. Adjust the bias tune control, while repeating the record/playback procedure if necessary, until both signals read - 20 dB in playback.

After the stop button was pushed, the master fader control is automatically released and the level returns to the "Up D" value.
Tips on Setting Record Levels
The LED level meters of this cassette deck are free of "overshoot" problems and display peak levels with a high degree of accuracy. For good recordings, it is essential to maintain a high signal-to-noise ratio. This is achieved by putting as much signal on the tape as is possible without producing distortion. Setting record levels too low will result in noisy recordings, while too high recording levels cause distortion. Finding the proper level between these two extremes is what good recording is all about. This task is facilitated by this deck's level meters which cover a wide 50 dB range and accurately display even very short signal peaks. Refer to the chart as a guideline to set recording levels.

Dolby NR Switch Operation When a Dolby noise reduction system is to be used, set the On/Off button (left button) of the Dolby NR switch (1 5) to "On" and select the desired system with the C-Type/B-Type button (right button).

Maintenance
The cassette holder cover of this cassette deck can be easily removed. Perform cleaning or demagnetizing after removing the cover. In ordinary use, this cover should always be attached.
Cleaning should always be performed in the direction of the arrows in the chart (direction of tape travel).

Demagnetizing

After a longer period of use, there can be a build-up of residual magnetism in the playback head, record head and erase head. Such residual magnetism can induce noise and partially erase the high frequencies of a tape being played. To prevent this, you should demagnetize these parts about once every 50 hours of use with the Nakamichi DM-10 Demagnetizer (optional) or any other properly designed demagnetizer. Note: Always switch off the power to the deck before starting the demagnetizing procedure.

Cleaning Procedure:

1. Remove the cassette holder cover. 2. Use the enclosed cotton-tipped sticks and-with very light pressure-clean the parts indicated in white on the illustration. In case of severe contamination, dip the cotton tip in the enclosed alcohol before cleaning, or use the enclosed plastic stick with a sponge tip screwed onto its end and dipped in alkhol.

Head and Transport Cleaning
It is very important to regularily clean the surfaces of the record head, playback head and erase head as well as the capstans, pinchrollers and all other parts which come in contact with the tape. Tiny particles shedded from the tape onto these parts, as well as dust accumulations etc. become the cause of drop-outs, and severely degrade frequency response and wow-and-flutter characteristics. Be sure to always keep the parts shown in white on the illustration spotlessly clean.
