Dolby B NR HighCom Soft Touch Metal Tape

The Grundig CF 5100 is a stereo cassette deck with Dolby B and High-Com noise reduction, it was introduced by Grundig in 1981.

The main features of the Grundig CF 5100 are: 2 heads, analog 3 digit tape counter, tape type selection with support for normal, chrome, ferro-chrome and metal tapes, belt driven single-capstan transport.

Typical front loading cassette deck with the cassette compartiment located on the right side of the deck. Tape eject is operated mechanically and the cassette needs to be placed directly over the head block. Additionally the heads can be easilly accessed for cleaning.

Level meters used on the CF 5100 are generic digital peak reading meters. Soft-touch controls for fast and easy transport function selection of the CF 5100.

The Dolby-B system reduces tape hiss on tapes recorded on the CF 5100 by as much as 10 dB at the highest frequencies. The High Com system (as used in the CF 5100) 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.
