Townshend Seismic Isolation Platform : Decoupling
Price for one piece
-
- Especially designed to isolate individual components such as CD players, turntables, DACs, preamplifiers, power amplifiers and streamers from vibration.
The Importance of Vibration Isolation
Vibrations affect the reproduction of sound through hi-fi systems. Although many of these are small and may go largely unnoticed, vibrations have a negative impact on the quality of sound in virtually all hi-fi components.
- Turntables are highly sensitive to vibration, which raises the noise floor, degrading the sound not to mention stylus jump due to footfall.
- With silver-disc players, vibration affects the laser mechanism and the crystal oscillators introducing severe sound-degrading jitter.
- With tube or valve amplifiers vibration rattles the microphonic electrodes, especially the grids.
- Transistor amplifiers have microphonic components, including capacitors and connecting wires which move relative to one and another generating rogue voltages. All of these mechanisms will degrade the delicate audio signal.
- Computers, streamers and DACs are highly susceptible to mechanical noise as they all contain vibration sensitive crystal oscillators.
Rigidly spike or cone mounted speakers transmit energy into the floor radiating vibration throughout the room and ultimately, through your rack and into your equipment. This seriously degrades performance as described above. Spike and cone mounted speakers cause the whole room structure to vibrate, often resulting in an unrealistic boomy bass whilst masking subtle detail. Further, this unwanted structural vibration can seriously irritate your neighbours.
The Seismic Isolation Platform includes a durable slim steel top plate that integrates unobtrusively under any hi-fi component. The acoustically dead constrained-layer damped plate combined with a Seismic Load Cell™ attached to each corner is the ultimate combination to absorb and isolate unwanted vibration, including structural, air-borne and that generated by the hi-fi equipment.
The secret is to fully float your whole Hi Fi System independently from the speakers and the floor. Townshend have devised a complete solution that to allow this to be done in an optimum way.
Seismic Load Cell™
The key component is the Townshend Seismic Load Cell™. The Seismic Load Cell™ consists of a high quality alloy steel compression spring surrounded by a flexible synthetic rubber jacket with two end plates. Screw threads in each plate facilitate height adjustment and provide attachment points. A movement-sensitive, air-resistance damper rapidly dissipates low frequency oscillation caused by disturbing the suspended equipment. Seismic Load Cells™ are very ‘soft’ and allow free movement in all three dimensions; up/down, left/right and back/forth. This unique solution blocks all deleterious vibration from 3Hz upwards and from all directions. As the frequency increases, the isolation gets progressively greater, ensuring that virtually no vibration can pass from and to the suspended equipment. As each hi-fi component is isolated, the sound progressively improves.
The singular Seismic Load Cell is available with seven different weight capacities, ranging progressively from 1kg up to 32kg. Virtually any weight of equipment can be isolated. The Seismic Isolation Platform is available in three standard sizes:
- Size 1 43x30cm (17×12”)
- Size 2 48x35cm (19×14”)
- Size 3 52x40cm (20.5×16”)
It is important to specify the weight of your equipment when ordering. Bespoke platforms are available for any size or weight of audio equipment.
