The Falcon Power Supply Unit (PSU) is a microprocessor controlled digital regenerative AC power source used for accurate speed control of a turntable motor. The PSU uses Direct Digital Synthesis (DDS) to create an extremely accurate and clean sine wave that improves motor speed stability and allows the user to precisely adjust the turntable platter rotational speed.

The PSU is extremely easy to use and set up. All of the operating parameters are stored in non-volatile memory and the device always power up with the last used speed and frequency offset displayed. The PSU is powerful enough to start up in either speed selection, so there is no need to start in 33 RPM, then switch to 45 RPM as in other units.

The Falcon PSU can be connected directly to the RoadRunner digital turntable tachometer via a 3 wire serial cable in order to synchronize its output with the direct measurement of the platter speed. Operation is completely automatic with no user intervention needed. The tachometer outputs the speed reading once per revolution. The PSU compares this reading to the speed on the display and can make micro-fine adjustments to the output frequency to lock the turntable speed to within ±0.005 RPM. The adjustment is done slowly and evenly over the entire next revolution and is inaudible to the listener (in most cases, the adjustment is <0.0005 RPM per step). 

The turntable remains on speed independent of the belt tension, bearing oil viscosity, drag from the needle or any other variables that cause the table to drift over time.

Just 3.5” x 2.5” x 1.2”, the Falcon PSU is the smallest most advanced turntable power supply on the market.

Comes with standard North American socket (NEMA 5-15) on the end of a 30” cable and universal input wall adapter.
