Victor NR-50 Noise Reduction Unit

The Victor NR-50 is a noise reduction system with Dolby B and C and JVC's ANRS and Super ANRS noise reduction, it was introduced by Victor in 1981.

The features of the NR-50 include.

Level meters used on the Victor NR-50 noise reduction system are generic digital peak reading meters.

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

Super ANRS developed by JVC and used in the NR-50 applies compression in recording and expansion in playback to improve dynamic range at high frequencies. Also Super ANRS is a highly effective noise reduction system that reduces tape hiss by boosting the signal-to-noise ratio as much as 10db over 5000Hz. Dolby C-type used in the Victor NR-50 provides 20 dB of noise reduction above about 1,000 Hz, fully doubling the amount given by B-type. To further maintain recording accuracy, the NR-50 incorporates a switchable multiplex filter. When you record FM stereo broadcasts, the MPX filter of the NR-50 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.
