Variable 33.3 rpm and 45rpm speed (can even set to 78 rpm) , motor driven with advance microprocessor controlled PWM MOSFET driver, ultra stable and precise speed control, can adapt to almost any turntable with smooth rim platter . PWM driving using the most power efficient way of design, both driver and motor will last much longer than conventional AC or DC driveing method , this is a digital driving technology, which will perform the most stable operation even with power line variation.
The motor and driver are fully mechanical de-coupled from the turntable , in order to ensure rumble free playback. It can upgrade your existing turntable to another level of performance without the need to spend thousands of dollars on buying another one .
Top control knobs for fine adjustment, rear coarse adjustment for different motors and spindle diameter. The motor come with this unit is replaceable by almost any DC motors, just two wire connection to the controller. Future upgrade is possible.
Two super elastic and super thin driving belts included for immediate setup, the ultra thin design of the driving belt ensure the most noise free driving , because mehancial vibration can hardly transmit thru a very thin elastic belt. Of course if higher driving torque required then one can use any flat driving belt as well.
Super low resonance material cover included for further reduction of residue motor noise.
You wil probably need to pay several thousands for other name brands with even lower technical level or out-dated designs.
Feedback from genuine customer (musician : professional violinist):
The improvement is substantial-the choral parts such as in Misa Criolla with Jose Carreras sound for the first time in tune. The same for sustained piano chords. When I aligned the speed with the 1khz sound on the computer I got just the slightest fluctuation in unison. It would be impossible to get perfect unison as I can hear fluctuation in the test generator sound itself just on the computer alone. The rumble is virtually nonexistent (I have to increase the volume to about 11:30 for the onset of the rumble and I listen to just past 9:00 o’clock volume the loudest). Also the clarity micro dynamism (musical inflections) and imaging has improved.
