If the recording level is set at maximum, the signal-to-noise ratio (S/N) and the dynamic range (range of sound volume) will improve, but if it is set too high, the sound quality will deteriorate. On the contrary when the recording level is set too low in order to avoid distortion, tape hiss noise becomes too evident. Even among tapes of the same type, the tape characteristics may differ according to maker and kind. It is therefore important to determine the optimum recording level for each tape used, in order to obtain good recordings by fully utilizing the tape characteristics. ¦U The optimum recording level depends on the type of music to be recorded and also on the type of tape used. ¦U Generally, adjust the recording level so that the level meters indicate around the 0 dB point for normal or chrome tapes or the +3 dB point for metal tapes at the highest signal level. L dB R -00 -20 -10 -6 -3 0 +3 +6 ¦U Proper setting for normal or chrome tapes. L dB R -00 -20 -10 -6 -3 0 +3 +6 ¦U Proper setting for metal tapes. L dB R -00 -20 -10 -6 -3 0 +3 +6 ¦U Too low of setting, too noise. L dB R -00 -20 -10 -6 -3 0 +3 +6 ¦U Too high of setting, distorted sound. MAKING A BLANK SPACE ¦U In the recording pause mode, press the RECORD/RECORD MUTING button again. / ¦U The unit will make 4 seconds of blank space, then enter the recording pause mode. 12 RECORDING A CD AUTOMATICALLY When this unit is connected to a Sherwood DIGI LINK ¥² CD player controlled remotely by the DIGI LINK system, the CD Synchro record function can be operated. ¦U Before starting CD synchro recording, adjust the recording level and the balance. 1 Repeat steps 1, 2, 3 and 4 of "RECORDING" Procedure. 2 According to the tape length edit the tracks to be recorded on the CD player referring to the operating instructions of that. 3 Start CD syncro recording.

NOTE ¦U Only when the erase protection taps on the cassette tapes are in place, CD synchro record function will be operated. ¦U During CD synchro recording, if other program source on the receiver is selected, the unit stops CD synchro recording and starts recording the selected program source. DUBBING FROM DECK B to DECK A Open the cassette door by pressing the EJECT button and load a blank cassette tape into DECK A and prerecorded cassette tape into DECK B. Select the reverse mode 1 2 REVERSE : Recording of a single side. : Recording of both sides. 13 ENGLISH ENGLISH 3 Press the DUBBING MODE button to select the normal or high speed(1. 5 times normal speed) dubbing. 4 To stop dubbing. ¦U High quality sound will be obtained in the nomal speed dubbing mode. DUBBING NORMAL HIGH ¦U Then dubbing will start. NOTE ¦U During dubbing, the Dolby NR is automatically set to OFF and the recorded tape can be dubbed as it is. ¦U During dubbing, the settings of the REC LEVEL and the REC BALANCE controls are ignored. SELECTING A COUNTER MODE There are two kinds of counter mode: tape counter, time counter for displaying the elapsed recording or playback time. [. . . ] Since the system is automatically engaged during the recording process only, the audiophile can enjoy the full benefits of any tape without worrying about proper adjustment of switches and encoding/decoding controls. ENGLISH 250µW/M --0 --5 Level (dB) --10 Dolby-HX-PRO ON --15 Dolby-HX-PRO OFF --20 10 100 1k Frequency (dB) 10k PRINCIPLE OF DOLBY NR SYSTEM The Dolby NR system functions so that it automatically increases recording levels of medium and high frequencies when the recording signal level is lower than the specified level (encoding), and automatically reduces the output level to the normal level during playback (decoding). In this way, the tape hiss noise is remarkably reduced without affecting the sound quality. The Dolby NR system used in your cassette deck improves S/N ratio by about 5 dB at 1kHz and about 10 dB at 10 kHz Btype and by about 20 dB on the most frequency range in C-type. Furthemore C-type gas the anti-saturation network which reduces the affects of high frequency saturation, improving high range frequency response.
