Burmester 069 CD player : CD Player

The Reference Line CD player 069 sets the ultimate technical standard for CD playback. Cutting edge technology combined with a proprietary belt-drive system form the technical basis for providing a musical experience of the highest order. Dieter Burmester invented the belt drive for CD players in 1990 and only a year later introduced the first CD player with a belt-driven CD platter to the world market. Like an analog turntable, the belt drive in a CD player provides complete decoupling of the pick-up system, in this case the laser, from any mechanical interference by the motor drive. As a result the data on the CD is read with ultimate precision, translating into the decoding of the smallest musical detail as well as complex acoustic structures. Add to this the latest generation of DA conversion and you know that you will miss nothing on a recording: Spatial resolution, musical timbre, airy highs and deep, controlled bass.

Why a BeLT-DRIve sysTem?

Almost all available CD transports on the world market use direct-drive systems, i.e. CD platter, spindle and motor are a firmly fixed unit. Furthermore, most motors are cheesy little things running on cheap bearings and cannot guarantee a smooth rotation. Motor cogging as well as vibrations and mechanical resonance are transmitted directly to the platter and, hence, to the CD. This renders a faultless sampling by the laser pickup impossible. As a result, small parts of the signal are lost. These are the parts that the human ear translates as spatial image, focus and musical accuracy. Therefore, digital playback was criticized as “two-dimensional” and “synthetic.” Since, for obvious reasons, direct-drive systems never made it in analog turntables, in 1990 Dieter Burmester developed the belt-drive principle for CD transports and designed the first belt-driven CD-transport, with the 916, in 1991. Since 1995 the beltdrive mechanisms are now produced in house by Burmester Audiosys- teme. The advantages of a belt-driven transport are that the digital pickup is completely decoupled from interferences from the motor drive. The CD platter of the 069 sits on a 4 mm-thick spindle which rotates in a precision bearing with no more than three thousandths of a millimeter play . This guarantees an absolutely smooth rotation without cogging, be- aring play or vibrations and resonance. Hence, the sampling process is not subject to any mechanical jitter.

Why a DouBLe-ChamBeR housIng sysTem?

The drive rests firmly in a double-chamber housing system to further de-couple it from me- chanical and acoustical interferences such as footfall and sound waves from the speakers. The housing of the drive unit is made of 10 mm-thick aluminum plates and weighs 58.5 lbs. To further increase the 069’s interference immunity, the spike feet of the outer housing rest on a carbon fiber suspension as part of its own base.

Is ChangIng RoTaTIonaL sPeeD ComPaTIBLe WITh BeLT DRIve?

In contrast to analog record players which rotate during playback in constant angular velo- city, the CD must rotate in constant line velocity. That means that in order to obtain a steady data stream during the sampling process, the rotational speed of the CD must be continu- ally reduced since the circumference of the ‘grooves’ that the pickup traces increases from the inside to the outside. Ensuring the correct rotational speed at any point of the sampling process has been the greatest challenge in designing a belt-driven CD transport. It was met by developing a highly sophisticated microprocessor-based control unit. Its calculati- ons takes into account all variables of the drive unit such as motor, belt, precision spindle and stabilizer and guarantees the absolutely smooth rotation of the CD. Besides the low torque motor, a top Swiss product manufactured to our specifications, the precision spind- le and bearing are of a level of quality that no other standard CD transport approaches.
