Playback speed may be adjusted with pitch control.

To ensure the best response from the wide variety of tapes available adjustment of, bias and sensitivity, to optimum levels can be performed prior to recording.

The Dolby-B system reduces tape hiss on tapes recorded on the SR 3780 by as much as 10 dB at the highest frequencies. The three-head configuration of the SR 3780 requires a Double Dolby system, one for recording and one for playback. To further maintain recording accuracy, the SR 3780 incorporates a switchable multiplex filter. When you record FM stereo broadcasts, the MPX filter of the SR 3780 can be swiched on to prevent the standard 19kHz FM pilot signal from interfering with the noise reduction system.

To make live recordings this deck has 2 microphone inputs to connect microphones with a jack connector. For undisturbed listening a jack connector for a pair of stereo headphones is supplied. Connection to other audio components for plaback can be achieved by a RCA cable and recording from a source by a RCA cable.
