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

The High Com system (as used in the Telefunken CN 750) works as a broadband 2:1:2 compander, achieving almost 15 dB of noise reduction for low and up to 20 dB for higher frequencies, while avoiding most of the acoustic problems observed with other high compression broadband companders. A Subsonic filter is provided in the Telefunken CN 750 to prevent infrasonic signals generated when playing a warped record. These signals can upset the Dolby system and prevening it from functioning properly. To further maintain recording accuracy, the CN 750 incorporates a switchable multiplex filter. When you record FM stereo broadcasts, the MPX filter of the CN 750 can be swiched on to prevent the standard 19kHz FM pilot signal from interfering with the noise reduction system.

Connection to other audio components for plaback can be achieved by a RCA cable and recording from a source by a RCA cable.
