Ayre Acoustics 3-Phase Power Supply Power Supply User Manual


 
Overview and
Introduction
The dps turntable is manufactured in Germany by
Bauer Audio, with distribution in North America
handled by Ayre. The unique design of the dps
turntable design offers a compelling combination of
high performance, ease of use, and an elegant
appearance.
One key feature of the dps turntable’s design is the
use of a precision, high-torque 3-phase synchronous
motor. The platter itself is of relatively low mass,
and the proprietary zero-clearance main bearing
creates a constant load on the motor. This allows the
motor to precisely control the speed of the record.
The Ayre 3-Phase Power Supply is designed
exclusively for the dps turntable and supplies an
ultra-low distortion, analog-generated sine wave to
each of the motor’s three windings via three
zero-feedback power amplifiers. The turntable’s
speed may be electronically selected between 33-
1
/3
rpm and 45 rpm with the front panel button.
