Product Description
The ADS design includes two pure analog frequency generators featuring low distortion and noise; a high current Class-A/B amplifier that is transformer-coupled to the turntable output; analog control logic for low noise operation; 33/45 RPM analog speed adjustment controls with center detente positions that are factory calibrated. Created by our Director of Electrical Engineering, Michael Bettinger.
The Machine:
- The platter is started and stopped by the front panel Run/Stop momentary push button switch.
- The front panel contains a two-position push button switch for selecting either 33 RPM or 45
RPM operation. - There are separate speed adjustment controls for 33 and 45
RPM. - The controls have a detented center position that is factory calibrated for 60 Hz (33 RPM)
and 81 Hz (45 RPM). - The speed is continuously adjustable +/- 3 Hz
- Blue LED indicators adjacent to the controls indicate which speed is set at a glance.
