Strathearn SMA2

Description

Strathearn's aim with the SMA2 turntable was to improve on the performance of the best existing component arms and turntables, through the use of technology.

The SMA2 is a two-speed, manually operated, electronic servo, direct drive turntable with a precision, low mass pickup arm.

The low mass of the tonearm enables advantage to be taken of very high compliance cartridges.

Precision ball races provide almost frictionless vertical and lateral bearings, while the geometry has been designed to be as close to optimum as possible.

The new design of electronic servo direct drive motor in the SMA-2 has levels of speed variation (wow, flutter and drift) and vibration (rumble) that are so low compared with those on records, that further improvement would be of questionable value.

Because the motor speed is more accurate than the AC line supply frequency, Strathearn developed an electronic strobe using two light emitting diodes to allow more precise adjustment of speed.

Manual operation is made simple and convenient by touch buttons for jolt free operation.
