Turntable »Oasis«
The most prominent feature of the »Oasis« turntable is most probably its direct drive mechanism. In our never-ending search to improve sound quality, we did not stop short of evaluating different drive mechanisms or other alternatives such as belts of various consistencies. We quickly discovered, however, that belts, for example, impart a fundamental sonic characteristic on the sound. We therefore decided to forgo them altogether for this new model. As it turns out, the platter of the »Oasis« is magnetically driven instead of with a belt.
The drive mechanism consists of a ring shaped permanent magnet contained in the platter's bearing and four air-cored inductors on the »Oasis's« chassis plate. These inductors are adjusted and driven with utmost precision to different phase angles. Thus, the ensuing magnetic field rotates the platter. Well aware of the reason for the bad reputation and uneasy sound of the direct drive turntables of the 1970s and 1980s, we resisted tight regulation of the direct drive mechanism. Instead, we take advantage of the many years of experience and insight we gained from manufacturing our own “big” turntables. We use a precision bearing that is capable of smoothing out the drive's miniscule speed variations. The result is a direct drive process that allows an enormously quiet and stable operation, and in conjunction with the low rpm drive, eventual irregularities are far beyond the allowable frequency of human hearing (the frequency of the drive 3Hz @ 33 rpm).
The Brinkmann Oasis turntable features an attachment for the tonearm base that fits with a machined culet and can be fixed or loosened via a single screw. This enables the user to adjust the effective length of the tonearm while the base is allowed to move freely.
The tone arm base can be equipped with a wide variety of mounting from 9 inch to 10.5 inch arms by request. It is possible to lead the cables of the tone arm directly to a pre-amplifier or phono stage, or to mount RCA or XLR output jacks.
The crystal glass platter gives a very smooth and even surface; with a stainless steel insert that is located unneath the reord label. A plastic ring in the middle of the plate lifts the record minimally and is pressed back onto the platter by the record clamp at the outer rim of the label. That way, there is a good contact between record and platter, minimizing resonance. Mildly warped records are straightened in the process. The turntable platter has a low resonance because of its mixture of lead, dural, aluminum and copper.
The special shape of the chassis was designed to remove resonances and with the addition of the wooden plinth of the chassis, a solid, deep and resonance free bass reproduction is accomplished. The frame can be ordered in one of three different types of wood; namely - cherry, maple or makassar (ebony). Finally, three height adjustable spikes allow for precise leveling and optimal contact of the turntable to your choice of platforms (although we recommend the HRS' M3 Isolation Base).
