Setting this mode permits the arrangement of the begining portion of the opposite side of the tape.) 1. Press the POWER switch q to the ON ( ) position. 2. Load the cassette tape to be played on deck A and the one to be recorded in deck B w. 3. Select the position of the REV MODE switch e. 4. Press the SYNC REV button i to set the SYNC REV Mode.

The HIGH DUB indicator will light at this time. 6. To stop dubbing, press the STOP ( ) button t of deck A or deck B. ¼ When dubbing, the recording level and the Dolby NR recording will be the same as those of the playback tape, regardless of the positions of the REC LEVEL control and the DOLBY NR button. ¼ When listening to the playback sound during normal speed dubbing, the DOLBY NR switch remains off even if it is pressed. ¼ Operation using the REC MUTE and PAUSE ( ) buttons y, u of deck B is permitted during normal speed dubbing. SYNCHRO RECORDING PROCEDURE (Deck B) ¼ The following operation is available only when a MARANTZ CD player with the synchro recording capability is connected to the cassette deck. ¼ To use synchro recording, connect the remote control cord terminals on the CD player and cassette deck. 1.

DOLBY B AND C NOISE REDUCTION SYSTEM í The Dolby noise reduction system substantially reduces the tape background noise (hiss) inherent in the cassette medium. í Tape background noise consists primarily of high frequency 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, but the level of background noise generated by the tape is greatly reduced. í The operating principle of Dolby C NR is similar to that of Dolby B NR except for the encoding/decoding response curves. The noise reduction effect obtained with Dolby C NR is up to 20 dB, compared to 10 dB with Dolby B NR. In addition, Dolby C NR uses an anti-saturation network and spectral skewing circuitry for a significant improvement in the dynamic range of the mid-to highfrequencies. 11
