Linear time tape counter PLAY TRIM control adjustment Use the linear time tape counter as an aid in locating a point on a tape (–99 min. 59 sec. to 99 min. 59 sec.). To set the counter reading to "0:00", press the COUNTER RESET button. Note: Precision of counter The tape counter is not a clock, and so there will be some errors in the time display compared to the actual playing time (this cannot be avoided, as a suitable method is adopted to provide a time display not only during recording and playback, but also during fast forward and rewind). The error depends on the type of tape being used. When distortion or the absence of high frequencies is noticeable while playing a tape recorded on another cassette deck, compensate the high frequency response with the PLAY TRIM control. When high frequencies are too loud, attenuate the high frequencies. When high frequencies are too soft, boost the high frequencies.

See “Setting the recording level”. 0 DOLBY NR button setting (in step 2) Dolby noise reduction is an extremely effective method of reducing undesirable background hiss on tapes. This unit incorporates both Dolby B NR and the newer Dolby C NR system. Dolby C NR is approximately twice as effective as the earlier Dolby B NR. Each time this button is pressed, Dolby NR switches as follows: 3 B (MPX off) Recording with DOLBY B NR Only the B indicator lights. 3 C (MPX off) Recording with DOLBY C NR Only the C indicator lights. 3 B MPX on Recording an FM broadcast with DOLBY B NR B and MPX FILTER indicators light. 3 C MPX on Recording an FM broadcast with DOLBY C NR C and MPX FILTER indicators light. 3 OFF 8 Recording with no noise reduction No indicator lights. 10 MPX filter FM stations transmit a 19 kHz pilot signal in addition to the broadcast program. Sometimes this pilot signal may leak into the audio output depending on the tuner and broadcast conditions. This signal can cause improper operation of the Dolby NR systems. Activating the MPX filter (B TYPE/C TYPE MPX ON settings) will effectively remove the signal.  Tape remain indicator SOURCE TAPE L dB –30 R 20 15 10 8 6 Linear time tape counter 4 8 6 4 Ÿ 0 2 4 6 + Highest peak for Metal position tapes L dB –30 R 20 15 10 8 6 4 Ÿ 0 2 4 Ÿ 0 2 B/ MPX FILTER 4 6 Peak level meters + C/MPX FILTER indicators To stop recording temporarily Highest peak for Normal or High position tapes 10 ŸBC Note: The tape remain indicator may differ depending on the tape length, tape type or the size of hub.

In addition to these functions, you can refine your recordings by using the Auto Tape Tuning function, which adjusts the recording bias and sensitivity for each tape you use. Auto tape tuning function Output level (dB) The auto tape tuning function improves the quality of recording, permitting precise adjustment of the deck's recording bias and sensitivity for best results with every tape you use. With the auto tape tuning function, the recording characteristics (recording bias and sensitivity) are automatically adjusted in two frequency ranges (500 Hz and 10 kHz) while performing recording and playback operations simultaneously for about 20 seconds, to accurately match the characteristics of the loaded tape. For example, the recorded (output) level (A in the figure) may differ from the recording (input) level (B in the figure), due to widely varying characteristics between brands of cassette tapes. Using the auto tape tuning function, these differences are effectively eliminated by adjusting the recording bias (for high frequencies) and sensitivity (for overall frequencies) according to the loaded cassette tape, making a significant contribution to overall recording quality (C in the figure). A B Input level C Frequency (Hz) <Operation> 1. Set the PLAY TRIM control to the center position. 2. Press the REC/PAUSE button to enter the rec pause mode and adjust the recording level with the REC LEVEL control. 3. Press the AUTO TAPE TUNING button. The TAPE TUNING indicator blinks and the deck determines the optimum recording characteristics (bias and recording sensitivity) according to the loaded cassette tape in about 20 seconds. After completion of auto tape tuning, the tape is automatically rewound to the point where auto tape tuning began and the deck enters the rec pause mode. The TAPE TUNING indicator lights up. 10 ¶ Auto tape tuning may not function with a tape of poor quality. In this case, the tape stops and the TAPE TUNING indicator does not light up. ¶ The adjusted recording characteristics are not cancelled as long as the TAPE TUNING indicator is lit. When you no longer need this adjustment, press the AUTO TAPE TUNING button in rec pause mode or stop mode. The TAPE TUNING indicator goes out. This adjustment is also cancelled when the ) button is pressed. Note When loading a tape of different brand even if whose tape types are the same, perform the auto tape tuning operation again even when the TAPE TUNING indicator lights up. DOLBY HX PRO DYNAMIC BIAS SERVO SYSTEM This unit incorporates the Dolby HX Pro system which automatically controls the effective bias to reduce distortion and noise, improving high frequency response during recording. Tapes recorded with this system retain the same high quality even when played back on other cassette decks. Dolby noise reduction and HX Pro headroom extension manufactured under license from Dolby Laboratories Licensing Corporation, HX Pro originated by Bang & Olufsen. “DOLBY”, the double-D symbol and “HX PRO” are trademarks of Dolby Laboratories Licensing Corporation. Synchronized recording function When operating this unit in combinaton with the YAMAHA CD Player which has SYNCHRO button on its remote control transmitter, CD Synchronized recording function can be utilized. This function is operated with the remote control transmitter of the CD Player. (Regarding the operation, refer to the manual of the CD Player.)  PLAY ENGLISH ! COUNTER RESET REC MUTE OPERATION — Inserting a blank space during recording During recording MUTE/ SEARCH MUTE/SEARCH 0-RETURN OPERATION — To return to the "0:00" point During recording COUNTER RESET The counter reading returns to "0:00" and this point is memorized. A 4-second blank interval is automatically recorded on the tape, and then the deck enters rec pause mode. If a blank interval longer than 4 seconds is desired, keep pressing for as long as you want. When the MUTE/ SEARCH button is released, the deck enters rec pause mode after making a 4-second blank interval. To resume recording, press the 3 PLAY button. « ! The tape will be automatically rewound to the "0:00" point and the recording mode is canceled. Note: The tape will stop at the point slightly ahead of the “0:00” point (around – 0:01). REC RETURN OPERATION — To return to the point at which the recording previously started During recording ! ¶ If the 3 PLAY button is pressed during recording, rec return operation automatically rewinds the tape to the point where the 3 PLAY button was previously pressed. 11  CASSETTE TAPES CASSETTE TAPES There are many different types of cassette tapes available. However, they all conform to standard specifications so any brand may be used with the deck. ¶ Classification of Cassette Tapes by Formulation Cassette tapes are available in four basic types depending on their formulation, or type of magnetic material and manufacturing process. These four types are commonly known as Normal (Type I/NORM), Chrome (Type II/HIGH <CrO2>), Ferrichrome (Type III/FeCr), and Metal (Type IV/ METAL), and they each require specific tape deck adjustments for optimum performance. * YAMAHA does not recommend the use of 120-minute length cassettes since the extreme thinness of the tape makes them susceptible to mechanical and recording problems. AUTO TAPE SELECTOR DETECTION SLOTS The deck has a built-in Auto Tape Selector which automatically adjusts for the proper bias, level and equalization according to the tape formulation — all you have to do is to load a cassette and the Auto Tape Selector does the rest. The Auto Tape Selector determines what type of tape is loaded by sensing detector slots on top of the tape shell. Each tape formulation has its own characteristic hole markings standardized by the tape industry. ¶ Early model Metal (Type IV/METAL) tape formulation cassette shells do not have the slots for Auto Tape Selector operation. As a result, early model Metal type tapes recorded on another deck will be played back with the deck at the Chrome (Type II/HIGH <CrO2>) settings. YAMAHA does not recommend recording with this kind of tape. ¶ The deck does not have the required setting for Ferrichrome (Type III/FeCr) tape, since this tape formulation is not widely used. Should you use a Ferrichrome tape, it will be recorded and played back at the Normal (Type I/NORM) settings, which will result in an unnatural high frequency emphasis. This effect may be compensated for somewhat with the auto tape tuning operation or by using the PLAY TRIM tone control and/or the tone controls of your amplifier/receiver during playback. TYPE II Detector slots 12 PROTECTING YOUR RECORDINGS All cassette tapes are provided with erasure protection holes to prevent accidental erasure of recorded contents. There is a small tab covering the hole on each side of the cassette, and it should be broken off after recording on the tape. Without this tab covering the hole, it is impossible to record onto that tape. Thus, you can safely protect a recording for as long as you wish without fear of accidental erasure. Should you wish to use a cassette tape protected in this way for recording, simply covering the hole with adhesive tape will permit erasure and re-recording. ¶ When using Chrome (Type II/HIGH <CrO2>) or Metal (Type IV/METAL) tapes, make sure you do not cover the hole intended for the Auto Tape Selector operation. TAKING UP SLACK IN THE TAPE As a precaution against tape entanglement and damage, remove any slack in the tape before inserting cassettes into the deck. This is accomplished by inserting a pencil, pen or similar object into one of the spools and gently winding it until all the slack is removed. You do not have to wind it too tightly. Be careful not to touch the tape part itself. It is very delicate and touching it may damage the tape and its recorded contents. TYPE IV Detector slots STORING CASSETTES After putting a cassette tape back into its case, store it in a location away from exposure to direct sunlight, humidity, high temperatures, and magnetic fields (away from television sets, speakers, etc.). High temperatures and humidity will damage the tape itself, while exposure to magnetic fields may cause a loss of recorded material. Avoid touching the tape surface with your fingers, since dirt or finger oil will contaminate the deck’s heads.  CLEANING OF THE TAPE PATH Continued high quality performance of your deck is dependent upon periodic cleaning of the heads, capstan, pinch roller, and all surfaces over which the tape travels. Normal use will cause an accumulation of dirt and dust on the heads, capstans, and pinch rollers. This can lead to poor sound quality, drop outs (intervals with no sound), unsteady tape speed, loss of high frequency response, etc. Thus, clean the heads and all surfaces over which the tape travels with a commercially available cleaning cassette. DEMAGNETIZATION After 20-30 hours of use, enough residual magnetism will build up on the heads to cause poor high frequency reproduction. At this time you should use a commercially available head demagnetizer. ¶ When demagnetizing the heads, be sure to follow the instructions of the head demagnetizer carefully. OPTIONAL REMOTE CONTROL TRANSMITTER With the optional remote control transmitter RS-KX1, you can operate this unit at your listening position.
