Easy recording for your benefit
The Marantz SD4050 offers a total solution for all your tape playback and recording needs with it's double auto-reverse cassette decks. The cassette deck can play three hours of non­stop music and offers superb recording facilities.
Tw in auto reverse deck
The twin auto reverse tape deck provides continuous play and copying from one tape to another. By using the Hi-speed dubbing functionality, the copying time will be reduced to half of the normal copying time. Making a copy of your favourite music was never this easy. Just place the tapes and activate the recording. Your cassette deck will do the rest.
Pitch control
For adjustment of the tape speed and tonal balance, pitch control has been incorporated in the cassette deck.
Dolby B/C & Dolby HX-pro
Dolby B/C provides a dramatic decrease of the amount of noise in recordings. To optimise the recording and playback, this selection should be used during recording as well as during playback. The Hx pro feature provides an increase of dynamics and is switched on by default.
D.Bus
To optimise equipment in terms of ease of use, Marantz has designed the D.Bus system. Individual devices inform each other, in order to automatically tune to the customers demands. At the same time received remote control commands are communicated via this bus. This enables equipment without IR­receiver, like a cassette deck or tuner, to be controlled via a Marantz Remote control.
