Turntable TT-2 Deluxe

First principles

Audio Note™ turntables are all designed and built according to a core set of four fundamental insights into what delivers musicality. We have settled on these design principles after many years of experimentation and experience. They can be found on every Audio Note™ turntable from the TT-One right through to the TT Three Reference in which they achieve their ultimate expression. 

A suspended chassis attenuates vibrational energy from the speakers and the room to deliver purity of reproduction.

A low mass platter absorbs much less energy from the cartridge in the groove of the record without deadening the sound.

A vibration free high torque AC drive system delivers constant platter speed even when the grooves contain strong modulations.

The transmission of vibration in our turntables and arms is managed through the use of materials with different resonances and mass, so that energy is led away from the cartridge, where it does harm to the sound.

Expect even more… 

The TT-Two is built to give an even more generous measure of musical enjoyment, particularly when paired with an Audio Note™ arm to create a combination able to punch well above its price point.

It has a high quality aluminium sub-chassis with optimised three-point suspension geometry. Two opposed AC motors deliver twice the torque to the low-mass acrylic platter and also have the benefit of further stabilising the suspension.

The robust and long-life bearing features a sintered and polished shaft in a brass tube with a hardened thrust plate and a precision ground steel ball. 

The TT-Two is available in black ash, beech, rosewood and cherry and represents long lasting value in analogue replay as its predecessor The Systemdek IIx on which is it based..

Turntable TT-3

The TT Three Reference incorporates what we consider to be the ultimate solutions to most of the solvable problems in vinyl replay. It has three speed settings, 33, 45 and, unusually for a turntable in this price range, 78 RPM. All speed settings have adjustment, the 78 setting over a range from about 60 to over 120 RPM in order to play the many older 78s that were not cut at a true 78 RPM.

The TT-Three Reference comes as standard with a single tone arm support. To facilitate the use of multiple cartridges it can be ordered with two or even three tone arm supports.

Drive System

Audio Note does not share other manufacturers’ enthusiasms for high mass turntables. Very heavy, dense platters may be cheap to manufacture and look impressive, but in our view they all to a greater or lesser degree (depending on material choices) store and reflect energy which results in less than optimal playback. 

The use of high mass platters has become popular for three reasons:

1. It has high rotational energy, due to its mass.
2. It therefore allows the use of an inexpensive motor and drive system
3. It looks physically impressive, but has several sonic problems because,

High mass has long and slow mechanical resonance recovery, the higher the mass the slower the recovery time, this allows the energy from the replay to stay immediately below the record being played for long enough to influence and mix in with the part of the groove being tracked at any point in time and as the record is played from the first track this influence increases as more energy is stored and reflected both ways.

In stark contrast the TT-Three Reference platter is light, highly inert and made from Lexan (bullet proof glass or polycarbonate) which has virtually no reflective or resonant storage problems, it weighs less than 900 grams and therefore has ultrafast recovery time, add to that the fact that polycarbonate has one of the highest energy absorption coefficients known to Man and you will see why this is the only proper solution combined with a strong drive system. 

So instead of the rotational mass choice of all the popular and expensive high end turntables in the TT Three Reference the rotational energy is produced in the drive system where it can do no sonic harm. To achieve this the TT Three turntable uses three large and very powerful AC motors, each pulling with more than one BHP for a platter-mass inertia equivalent of more than a half a ton, but without the drawbacks of a high mass platter. The motors draw so much power that each motor has its own outboard power supply. The speed of the motors is digitally frequency locked by a master control unit.

A rubber belt drives the platter on the outside of the platter which makes changing belt and pulleys (for 78 RPM) a simple and easy matter. Most suspended turntables require the platter to be removed and they often shed the belt when the motor(s) are started.

Suspension

Keeping faith with our established design principles and in common with the other Audio Note turntables, the TT-Three Reference are a three point suspended design. Unlike other systems it is centred at the bearing, which is also the epicentre of the motors' inertia. This completely avoids the most common problem in suspended turntables where the motors and suspension are misaligned and as a result generate a resonance as the platter moves between the centre of the motor and the centre of the suspension.

A properly dimensioned three point suspension is a natural 18dB per octave third order mechanical filter. The resonant frequency of the TT-Three Reference is set at 2.4 Hz; so low that it makes the turntable virtually impervious to outside interference with a minus 55dB immunity at below 20Hz.

To further enhance stability, as well as ensure the simplest set-up, the sub-chassis has three wings. One locates the arm in the conventional position on the far right, while the other two hold mass balancing weights – each an exact weight equivalent of an arm + cartridge mass. Each suspension spring is therefore loaded equally, removing the need ever to adjust the suspension. 

Arm Support

The TT-Three Reference can be ordered to accommodate one, two or three tone arms of two types only: the Audio Note™ ARM Three and the Audio Note™ AN-1s. We consider most other tone arms unsuitable because they are not designed in a way that leads energy away from the cartridge, down the arm tube through the bearings and arm pillar into the sub-chassis, to be dissipated there. 

Materials

The main frame and suspended system on the TT-Three Reference is machined from aircraft grade aluminium, the most ductile and therefore naturally inert aluminium available, making it perfect for dealing with the wideband energy generated by the stylus tracking the groove and the speakers energising the playback environment. The base of the turntable can be ordered in finishes to match most Audio Note™ loudspeakers.

Set-Up

It could hardly be simpler. Drop in arm with cartridge mounted and height preset, set tracking weight – and play music.

 

 

 

 

 

 

 


 

The AN-S4 is a passive device, designed to convert the mainly current output of your Moving Coil cartridge (MC) to a higher voltage, low current signal of sufficient strength to allow a Moving Magnet (MM) phonostage to amplify it to a suitable level.

The internal transformers used in the AN-S4 are manufactured by Audio Note (UK) exclusively. Each transformer is made from 0.1mm laminated super mumetal 250 and wound with 99.99% pure Silver wire. Each Transformer is then housed in a mumetal screening canister to minimize noise and interference.

The AN-S4 can be supplied in a variety of versions, as listed in the table below: -

AN-S4L 3 Ohm input impedance
For cartridges with an internal impedance of 1 Ohm, primarily designed for use with the Audio Note (UK) IO range

AN-S4LM 4 Ohm input impedance
For cartridges with an internal impedance of 1 to 2 Ohms

AN-S4ML 9 Ohm input impedance
For cartridges with an internal impedance of 2 to 4 Ohms

AN-S4M 16 Ohm input impedance
For cartridges with an internal impedance of 4 to 6 Ohms

AN-S4MH 36 Ohm input impedance
For cartridges with an internal impedance of 9 to 12 Ohms

AN-S4H 64 Ohm input impedance
For cartridges with an internal impedance of 16 to 21 Ohms

 

Audio Note Io Ltd Cartridge - Field Coil Cartridge

The Io range of cartridges from Audio Note UK are world-renowned for their stunning quality and their effortless ability to reproduce music to the highest standards and the Io Ltd. is at the very pinnacle of the range, and to many audio enthusiasts, at the very pinnacle of what is possible from music on vinyl. The revolutionary nature of the basic Io design runs contrary to most accepted design criteria, but the result is a small range of hand-made moving coil cartridges that are second to none in dynamic range, tonal balance, separation, timbral reproduction, and lack of colouration and surface noise. The cartridge designs do not lend themselves to mass production and as a result are extremely time-consuming to produce. They require a tone arm of very substantial rigidity, and must be combined with a matching transformer in order to achieve the best possible linearity and dynamic signal transfer. The Io Ltd. takes the design to a totally new level and is unique in its use of an electrically-generated magnetic field.

All Io cartridges are hand-built in the UK to exacting standards and the Ltd. features silver-wound generator coils and a titanium cantilever with an Audio Note AN Type-1 profile, diamond stylus. The Audio Note Io Ltd is unique among cartridges in its use of a field coil for a ‘permanent’ magnet, rather than a fixed magnet. This absolutely no-compromise design requires an external power supply to drive the field coil. A suitable unit is available from us. Please also note that tone-arm wiring will need to provide for two additional wires. Due to its hand-built construction, the Io Ltd. is usually not available from stock and is constructed to order.

Audio Note Io Gold Cartridge

The Io range of cartridges from Audio Note UK are world-renowned for their stunning quality and their effortless ability to reproduce music to the highest standards. The revolutionary nature of the Io design runs contrary to most accepted design criteria, but the result is a small range of hand-made moving coil cartridges that are second to none in terms of dynamic range, tonal balance, separation, timbral reproduction, and lack of colouration and surface noise. The cartridge designs do not lend themselves to mass production and as a result are extremely time-consuming to produce. They require a tone arm of very substantial torsional rigidity, and must be combined with a matching step-up transformer in order to achieve the best possible linearity and dynamic signal transfer.

All Io cartridges are hand-built in the UK to exacting standards and feature ALNICO high-density magnets, silver-wound generator coils and a titanium cantilever with an Audio Note AN Type-1 profile, diamond stylus. The Audio Note Io Gold has generator coils wound on a Permadure-iron former and is supplied with gold-plated gun-metal sides. The highest possible tolerances are used when selecting the cantilever, stylus and generator.

Please note that due to the hand-made nature of Io cartridges, they are often not available from stock.
