Setting the Reference Mono apart from the other Acutus versions is the gigantic power supply. Most regard a turntable power supply as just that, a turntable power supply with little more thought, but just the size of the Mono PSU lets you know otherwise.

With a DSP controlled Pre-Amp the regulate and fine tune speed and Twin Mono Power Amplifiers independently driving each motor coil, the leap in sonic performance is nothing less than staggering. The difference is not a subtle subjective difference but an immediately obvious improvement in all aspects that goes way beyond any expectation.

Lower noise floor, extension of both bass and treble responses and a significant dynamic improvement surpassing the Acutus Reference model. But even more startling is the naturalness and intimacy of the performance as it truly enters your space and deep into your soul.

The Acutus Reference Mono SP is an unashamed indulgence that offers a no cost compromise at vinyl reproduction.

Our hand assembled high torque AC synchronous motor spins the platter up to speed within seconds. Ten times more powerful than conventional turntable motors, this provides the ultimate control and stability. With twin round section drive belts the suspension is free to move without inducing speed variations common with flat belt designs.

Our unique two stage clamp performs dual functions, critical to the ultimate sonic performance you hear.First operation grounds the record to the main bearing, allowing vibration caused by the stylus to pass into the subchassis.

Reducing the noise floor of the record vastly improves the sound you hear and there is less damage or wear to records due to mistracing.

Second operation reflex clamps the vinyl flat to the platter surface, eliminating warps and air pockets underneath. The platter mat itself is a unique resin that reflects most vibration, keeping it in the record so it passes more quickly through the bearing into the subchassis.

The 10Kg Chrome plated aluminium platter is the focal point of the Acutus.

Secured with sixteen fixings, the 10mm aluminium disc which has had the resin mat cast and machined offers the perfect record interface. The mat reflects the most vibration except for very high frequencies, which after entering the platter body are rapidly constrained damped by the nickel and chrome layers.

The Acutus bearing spindle is the longest of all our turntables and is press fitted into the subchassis. Being fixed it is an inverted design so that the contact point is at the top and naturally has a low centre of gravity. At the top of the precision ground and tapered spindle a tungsten carbide ball mates with a uniquely design sapphire jewel, keeping the bearing point in a fix position with zero lateral movement. Doing this all but eliminates rumble noise present on all other turntables and the self-lubricating sleeve means no metal to metal contact during operation making our bearing totally silent and maintenance free for life.

It is critical for sound quality that the tonearm and bearing are rigidly coupled, any relative movement between them and information is lost forever. Our unique one-piece multi-fold aluminium casting provides maximum strength where required but allows for movement in non-critical areas, accepting the fact that nothing is totally rigid.

To eliminate the vibration from the record passed through the bearing, the casting is coated with a damping media of specific thickness so that both high and low frequencies dissipate with linearity and time frame, giving a neutral sound.

Our adjustable suspension system allows each supporting spring to tuned to the same frequency regardless of the load. This means that single or twin tonearm weights of up to 3Kg can be accommodated, the suspension will be balanced and a perfect pistonic bounce achieved. With an isolation frequency of 2.5Hz the pickup cartridge will not mis track, locked into position and all external vibration blocked.
