Lo-D D-900
Dolby B NR Full Logic 3 Head

The Lo-D D-900 is a stereo cassette deck with Dolby B noise reduction, it was introduced by Lo-D in 1978 with a list price of USD $529 and discontinued 4 years later in 1982.

The main features of the Lo-D D-900 are: 3 heads and off-tape monitoring, analog 3 digit tape counter and memory stop, manual tape type selection with support for normal, chrome and ferro-chrome tapes with additional manual equalization selection, belt driven dual-capstan transport.

Typical front loading cassette deck with the cassette compartiment located on the left side of the deck. Tape eject is operated mechanically and the cassette needs to be placed with the side to be played facing forward in the cassette well.

Level meters used on the D-900 are analog needle VU reading meters. Full-logic transport controls used on the D-900 let it respond to the slightest finger contact for fast and effortless transport function selection.

The Dolby-B system reduces tape hiss on tapes recorded on the D-900 by as much as 10 dB at the highest frequencies. To further maintain recording accuracy, the D-900 incorporates a switchable multiplex filter. When you record FM stereo broadcasts, the MPX filter of the D-900 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.
