Nimbus Records

From Wikipedia, the free encyclopedia

Nimbus Records is a British record company specializing in classical music recordings. Nimbus was founded in 1972 by the late bass singer Numa Labinsky and the brothers Michael and Gerald Reynolds and has traditionally been based at the Wyastone Leys mansion site, near Monmouth and the English/Welsh border. A core technical aspect of the company's recording philosophy was the early adoption of the Ambisonic surround-sound system invented by a group of British researchers including the late mathematician and recording engineer Michael Gerzon. The recordings have been made with a single-point array of microphones (developed by Dr Jonathan Halliday) which is equivalent to a form of soundfield microphone, encoded into stereo-compatible 2-channel Ambisonic UHJ Format and released on conventional stereo media.

An Ambisonic decoder is required to experience such recordings in their truest, surround-sound, form. These have never been widely available, so Nimbus recordings are typically experienced as undecoded UHJ which is compatible with normal stereo reproduction. Some listeners find that this results in an over-reverberant sound, particularly on early recordings.

The emergence of home-theatre systems with increasing emphasis on surround playback offers opportunities for domestic listeners to experience at least some of Nimbus' many hundred Ambisonic recordings in their original condition. For example, the company has issued a series of "DVD Music" recordings in which the original 2-channel UHJ masters have been decoded to loudspeaker feeds and issued on conventional DVD-Audio/Video surround format discs. In addition, Nimbus recordings are now often recorded in Ambisonic B-Format which can be decoded directly to a multichannel surround format compatible with conventional multichannel discs such as DVD or DTS-CD.

A large sub-label of Nimbus Records is the vocal series Prima Voce. This label specialises in the transfer of vocal records on 78 rpm disc dating from 1900. The method of transfer involves the use of thorn needles and a giant acoustic horn on a carefully-restored gramophone. No electronic processing is used: instead, the gramophone is placed in a living room environment and recorded Ambisonically, in surround-sound, from a typical listening position. Although controversial, the technique is capable of producing remarkably life-like results - particularly for recordings made 'acoustically' prior to the arrival of studio microphones in 1925. [[1]]

Nimbus Records was the first company to master and press Compact Discs in the UK, and developed and sold equipment for these purposes. It became part of the Mirror Group in 1987. Following the demise of Robert Maxwell, the equipment company was spun off and the intellectual property rights to the Nimbus Records catalogue were ultimately re-acquired by the original owners under the name of Wyastone Estate Limited. Wyastone Estate operates Wyastone Business Park, Wyastone Concert Hall and the Nimbus Foundation, Nimbus Records, and Nimbus Disc On Demand. The latter is a short-run disc manufacturing capability which has enabled Nimbus Records to make virtually all its catalogue of recordings from the earliest times available to record-buyers.
