CLASSIC POWER

The advantage of direct-drive turntables is their motor torque; belt-drive turntables typically use low-power motors coupled to a tiny belt to minimize motor vibration on the platter.

Flying in the face of convention, AVID utilizes a powerful synchronous motor and twin drive belts, dominating control over the heavy platter. The results are breath-taking, with deep dynamic bass and stunning rhythmic timing.

Our unique two-stage clamp performs dual functions, critical to the ultimate sonic performance you hear.

The first operation grounds the record to the main bearing, allowing vibration caused by the stylus to pass into the sub-chassis. Reducing the noise floor of the form vastly improves the sound you hear, and there is less damage or wear to records due to mistracking.

The 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 sub-chassis.

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

Secured with sixteen fixings, the 10mm aluminum 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 and damped by the nickel and chrome layers.

The Acutus bearing spindle is the longest of all our turntables and is press fitted into the sub-chassis. Being fixed, it is an inverted design so that the contact point is at the top and naturally has a low center of gravity. At the top of the precision ground and tapered spindle, a tungsten carbide ball mates with a unique design sapphire jewel, keeping the bearing point fixed with zero lateral movements. Doing this eliminates rumble noise 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 aluminum 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 be 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 will be achieved. With an isolation frequency of 2.5Hz, the pickup cartridge will not mistrack, locked into position, and all external vibration blocked.

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.

The Classic electronic power supply generates its own frequency using DSP technology, allowing the final speed to be accurately fine-tuned. With a large 80VA mains transformer, our power supply is actually a fully integrated amplifier providing a fixed output for the twin coils of the high torque motor.
