DBX Dolby B NR Wired Remote Control Full Logic Metal Tape

The Yamaha K-1d is a stereo cassette deck with Dolby B and DBX noise reduction, it was introduced by Yamaha in 1981.

The main features of the Yamaha K-1d are: 2 heads, analog 3 digit tape counter and memory stop, manual tape type selection with support for normal, chrome and metal tapes, belt driven single-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 which is opened by a damped mechanism.

Level meters used on the K-1d are generic digital peak reading meters. Full-logic transport controls used on the K-1d 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 K-1d by as much as 10 dB at the highest frequencies. Dbx Type II found in the K-1d is a simplified version of the Type I noise reduction system. The dbx Type II system was designed to be used with systems with limited bandwidth such as cassette based recorders and also uses a simple 2:1:2 compander to reduce noise. A Subsonic filter is provided in the K-1d 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 K-1d incorporates a switchable multiplex filter. When you record FM stereo broadcasts, the MPX filter of the K-1d 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. All main transport commands can be issued remotely with a wired remote control.
