Synchro-Wave Power Supply
The Basis Audio Synchro-Wave Power Supply is the finest power supply ever offered for turntables using AC synchronous motors. Delivering smooth, dual sine-waves with perfect 90 degree phase difference, of audio-amplifier quality distortion levels, the Synchro-Wave power supply brings Basis turntables to further heights musical reality.
The Synchro-Wave power supply offers the following features:
1. Speed selection: 33 1/3 or 45 RPM at the flip of a switch.
2. Dual-wave motor operation: 2 individual sine waves with exact, optimal phase shift are fed independently to each motor coil. Dual audio-quality high bias amplifiers are used for extreme low distortion power to the motor.
The benefits: Far smoother motor operation, lower cogging for more relaxed, lower grain sound. Greater detail, more precise imaging, and more natural decay characteristics are easily heard.
3. Stable, generated frequency of power.
The benefits: Perfect long-term speed stability. Sine wave frequency is crystal oscillator derived with final frequency being impervious to outside factors such as voltage change.
By feeding the AC synchronous motor an ideal signal source of 2 low distortion sine waves ideally phase shifted the Basis Synchro-Wave Power Supply brings greater “convincing power” to the sound of any Basis turntable. With short and long term drift reduced to non-existent levels the advantages of a belt drive system are retained while any possible limitations are eliminated. When combined with the Basis Microthin belt, this represents a leap forward in turntable drive systems.
