VARIOUS FUNCTIONS HELPFUL FOR HIGH QUALITY RECORDING This deck has a built-in Auto Tape Selector which automatically adjusts the recording characteristics according to the tape formulation (see page 12) and a Dolby HX Pro Dynamic Bias Servo System which automatically controls the effective bias during recording. 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 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). B Input level C A ¶ 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.

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.) Output level (dB) Frequency (Hz) 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
