Ortofon TA-110 Resonance Optimized Tonearm
Built upon the TA-100 and two areas of Ortofon's technological know-how, the new Ortofon TA-110 tonearm has gone to the next level by reducing unwanted vibrations in the tonearm.
Ortofon's material know-how is the first area of the Ortofon technology that was applied when developing the TA-110. As a specialist in technical rubber, Ortofon used one of its special rubber compounds when creating the specially shaped rubber with high vibration dampening properties. The rubber pieces are produced at the Ortofon technical rubber facilities in Nakskov. The second area of Ortofon technology is the extensive knowledge of vibration properties and characteristics. Ortofon has acquired this know-how via the developement of Bone conductors for the hearing aid industry. By using this knowledge and the related computer programs that simulated vibration in different shapes and materials, Ortofon came up with an optimized TA-110.
The TA-110 is a product with great benefits for the discerning analogue user.
The TA-110 is given a precision machined slit in the middle of the aluminium tube. A piece of Ortofon's special vibration damping rubber is inserted into the slit. An armtube without slit and rubber damper is symmetrical in a vertical and lateral plane with respect to vibrations. The slit breaks this symmetry, and mounting the rubber insert gives the desired damping. The TA-110 a static balanced gimbal type arm, which makes it easy to use and adjust for optimal VTF settings. Equipped with a standard headshell connector, TA-1010 can easily be adjusted in accordance with the included mounting template. The TA-110 has a standard 5-pin DIN connector for tonearm cable.
The tonearm geometry allows for a Baerwald alignment (also the IEC recommendations). The TA-110 can ideally be combined with MC PW, MC A90 and the new Ortofon Expression.
The TA-110 armtube is a lot less stressed than a conventional arm tube.

The effect of the rubber damping properties is evident from the Vibration Measurement chart below.
The armtube was mounted on the Brüel & Kjær Mini Shaker 4810, which was fed with a wideband pink noise signal. The vibration level was measured with a miniature Brüel & Kjær Accelerometer 4374 and a spectrum analyzer set to 1/3-octave resolution.
When taking the measurement uncertainty into consideration, the two armtubes show almost equal vibration levels, apart from the interval 1kHz to 4kHz (upper midrange/lower treble). As it is well known from the Fletcher-Munson curves, this is the interval where the ear is most sensitive, and this interval is also very important for a high quality music reproduction.
