Oyaide MTS-4e

The Dual-Spring vise structure is newly-developed for the contacts of our new outlet, SWD-XXX. Due to its strong holding power and 9mm wide contact area, the contacts tightly hold the inserted pins and reduce vibration at the contacts with no loss of signal transmission.

The chassis of MTS-4e is made of highly rigid stainless steel which is non-magnetic SUS 304. It protects from not only vibration but also electric-magnetic wave or external noise contermination. And all components, from 6.0mm thick contact down to stainless screws, are made of non-magnetic substance.

For the soldering connection, we employed SS-47 audio grade solder.
Compared to general solders which usually contain 3N (99.9%) pure tin, SS-47 contains 4N (99.993%) pure tin achieved by excluding impurities to the maximum. Furthermore, 4.7% silver and 1.7% copper are contained for the purpose of improvement of electric conductivity and durability.

The inlet is designed specially for MT series. The contacts are made of brass. The plating is a combination of silver (1.5μ) and rhodium (0.3μ). The body is made of 30%GF PBT.

We adapted VEM 313 sheet (Visco Elastic Material) for damping material for the inside of the chassis.

For its internal wiring, we employed 2mm 4N OFC copper wire. And for its insulator, we employed low-dielectric polyorefin resin.

For the better separation from the floor, we specially employed accurately machined brass spikes. Although it is set to four-point support as default, three point support is also applicable according to your preference.
