Turntable Power Supply & Motor Drive Versions
The turntable power supply upgrade consists of a high-grade motor and external boxed power supply. The motor plate is designed for drop-in replacement of your existing turntable motor. Three levels of upgrade are offered - Standard, Advanced and Ultra.
Motor Drives include all you need:
- Fully Built speed control / switch box with all leads and plug connectors
- 33rpm & 45rpm
- 50 x 110 x 180mm
- High Grade DC Motor with precision bored, high grip special plastic pulley designed for flat and round belts. The motor is supplied with a motor plate adaptor to enable fitting to your deck.
- Transformer for either 240/230v, 50Hz or 110v, 60Hz mains supplied.
- Strobe Card for easy and accurate speed setting.
- Fitting Instructions: The upgrade motors and turntable power supplied are fully built, no soldering is required - they are literally plug and play. Installing the motor in your deck is usually a simple procedure with full instructions provided.
Standard Upgrade - For All Decks
The Standard kit is for those on a severely limited budget. It is intended for low value decks that you wish to keep running - Comparison against the Advanced kit features mean the following:
- The circuitry lacks load compensation and so has a plus or minus of 0.4% speed drift from the inner to outer grooves
- Components are downgraded - the casework for the kit looks the same as the advanced, but has a red LED for identification
- Performance is a significant upgrade on most older motor drives but lacks much of the dynamics, bass power and accuracy of the advanced kit.
The power supply comprises: DC100 Motor, Advanced off-board control box and transformer power supply 240/230v 50Hz and 110v 60Hz options
Advanced Upgrade - For All Decks
Advanced switch box - identifiable by it’s green LED, the advanced switch box has a much more sophisticated circuit design with improved load compensation and higher instantaneous power delivery.
Ultra Upgrade - For Mid to High End Decks
Increased dynamics, bass weight and power are just a few of the major benefits to be gained with the Ultra upgrade.
Ultra Switch Box - identifiable by it's black aluminium case and blue LED includes the following features:
Component Upgrades - Many aspects of component specification have been upgraded, including low impedance / low leakage capacitors, highly specified diodes, special LED and heat sinks.
Circuit Upgrades - The circuit design has been refined to:
- Reduce electrical noise
- Reduce response time
- Increase current delivery
A special upgrade transformer is offered as an option for all switch boxes. This features a low noise advanced transformer, housed in an outboard enclosure. If you have an existing standard Origin Live transformer, then it simply substitutes in it's place.
The vastly increased delivery of instantaneous high current results in improved transparency, dynamics and deeper bass.
DC100 & DC200 Turntable Motor Option
The DC100 motor is included as standard with Origin Live motor kits and provides a huge performance improvement over traditional ac motors. The motor is high torque, near silent running with very low vibration. These advances are well reviewed and result in a more integrated sound, better timing, rhythm and pitch, freedom from coloration, improved transparency and dynamics.
The DC200 turntable motors are selected from the best DC100s for their additional quietness. Grading motors is a known phenomenon among turntable manufacturers and motors with higher vibration are often measured as such and set aside for decks lower in the range. The same is true for bearings in turntables. In the case of the DC200 there is little or no increase in performance as audible noise is not related to vibration.
We recommend that the Upgrade Transformer is a much higher priority than the DC200 as it improves performance very significantly.

Why Motors & Power Supplies Have Such A Powerful Influence On Turntable Performance
22 Years after purchasing my first turntable, it continues to amaze me how they all exhibit such major sound differences. It seems that every aspect of a turntable's design affects performance to a remarkable extent.
The motor and drive mechanism is possibly the most important aspect, contributing up to around 30% of overall performance. At first this may seem an unexpected statement and so by way of explanation, it is worth considering the following.
The purpose of a deck is to rotate the record at a precise speed in relation to the cartridge needle. No other motion must be present except the stylus movement through the groove. Any other motion will upset the correct movement of the stylus in the groove by adding to it or subtracting from it. The outcome is then amplified around 8000 times by the time it gets to the speakers.
To reduce motor vibration at source there are 2 approaches:
To produce a perfect, electronically synthesized sine wave to drive an AC motor.
To produce a perfectly regulated, load compensating DC current to drive a DC motor.
To be fair there are theoretical pros and cons to both methods. AC and DC solutions are both highly demanding and much depends on the quality of the motor. Origin Live chose to use DC motors, not so much for theoretical reasons, but on findings that DC motors generally run far more smoothly than AC motors – this is eliminating vibration at source rather than controlling it.
There is an argument that if a deck is completely inert, using high mass platters and carefully selected plinth materials, then motor vibration exert little influence on the resulting sound. It is surprising therefore, that the DC motor kits we supply, have an astonishing influence on such decks, some of which use platters in the 30kg (66lb) range. Quite how the vibration of a motor can upset such a mass takes some thinking about.
Features & Benefits
Control of Motor Energy Fluctuation
A high performance DC motor drive is dependent not only on motor quality but more importantly on a superb power supply.
Motors are hard to drive evenly with absolute precision. Eddy currents within the magnets cause severe power fluctuations among other factors. Negative voltage is fed back into the power supply. If not controlled, this results in motor vibration and severe loss of dynamics. Origin Live power supplies absorb such dips and surges in load, while adjusting to deliver copious and precise power with great speed.
The motor requires load compensation to maintain the turntable at a constant speed. This is because the drag of the stylus varies between the inner and outer tracks of a record. Many turntables suffer from about 1% speed drift. Not only is there variation from inner to outer tracks - there is also localized variation when the stylus negotiates complex or heavy passages of music.
To overcome these problems, the Advanced and Ultra power supplies have a load sensing circuit that maintains speed drift to a mere 0.1% (as measured by Hi-Fi News magazine - ten times better than the average turntable). The results are increased dynamics, better timing and pitch control, and a greater sense of drive and pace.
It is worth mentioning that for motors, a well designed mains regulator far surpasses the performance of lead acid battery regulation (as used by a few high end pre-amps).
As well as delivering superb speed control, the regulator is designed to produce very low noise, thereby reducing vibration still further. This translates into increased transparency and better definition.
The speed is easily switched between 33rpm and 45rpm using the knob on the speed control box.
Rear Panel Of Control Box
To cater for different sizes of platter or sub-platter, you can set the infinitely variable motor speed for your particular deck using preset dial resistors. This has the added advantage of making the motor simple to transfer should you ever change your deck.
The high-grade DC motors are best of class and characterized by:
- Low vibration.
- Smooth, powerful rotation.
- The motors are a breakthrough design with virtually no cogging effect due to iron-less cores. Cogging is the 'flick' that occurs as straight rotor windings pass between straight magnetic strips, i.e. the power transfer varies as the coils rotate from one magnetic pole to the next. More expensive motors have 'skewed' coils to ensure a smooth power transfer as the rotor rotates between poles.
This imparts a massive advantage over the inexpensive AC motors used in most decks, such as the Linn LP12, Thorens, Rega etc. These cannot run smoothly in comparison, no matter how sophisticated and expensive the power supply. The Origin Live DC motor is not only cog-less but also iron-less, which means that flux residue which occurs in cheaper motors is eliminated. Smoother, more efficient operation is the result. The Origin Live motors are also fitted with precious-metal brushes and are highly reliable. The bottom line is that the major source of vibration in any turntable (i.e. the motor) is dramatically improved. The benefits are difficult to imagine and fully appreciate until you hear them.
