The original Magnetic Wave Absorber, (MWA) series, was released by Oyaide in 2009 and has become very popular for its effects against noise generated by electronic magnetic waves around HI-FI equipment.

MWA-RC was created by the development that Oyaide applied this MWA material for a RCA cover cap for preventing EMA, noise and dust with easy application by simply attaching them to unused RCA jacks on your equipment. 

The Key features of MWA are: 

- Very easy to fit – simply place them on any unused RCA jack 

Manufactured from polypropylene which dampens the tiny vibrations found in the unused contacts. 


- The use of 1mm thick MWA absorbers on the caps reduces noise generated from the contacts. This material is called SENDUST which Oyaide have applied from a technology developed in Japan. By processing it into a flat shape this has increased the absorbing property against Electric Magnetic Waves. 

- The cap also prevents dust build up 

- Using the MWA-RC on multiple contacts can make the improvements much greater 

- Suitable for use on input and output jacks. 

MWA-RC are supplied in sets of 6 for only £15.00

Here are some comments from a customer who recently used these.......

Just a quick word about the Oyaide MWA-RC Magnetic Wave Absorbers.
Fancy spending £2.50 on a bit of plastic with a metal cap! Can't possibly improve the sound of your system can it?
OH, YES IT CAN!!
I can't believe the improvement these have made - so much so I've ordered some more to cover all my unused RCA sockets.
I have a Roksan Caspian M2 CD player, Arcam FMJ C31 preamp with two P38 power amps and Ruark CL20 speakers all lashed together with top quality wires. Its a great system which has always sounded nearly spot on, but....... 
The addition of these little beauties has smoothed sibilants, tightened up the bass and made silences darker.
Easily the best few quid I've spent, has made my system more "listenable" and had me digging out loads of CDs 'til late last night.
Many thanks for perfecting my system (until the next tweek or upgrade!!)

In the MWA electric wave absober pasted on the top MWA-RC, the material called SENDUST alloy which has strong noise absorbing property is mixed into as powder. This metal was develped in Sendai, Japan in 1930's, is composed of Al, Fe, SiO2. And it is processed into flat shape powder which has higher absorbing propaty against electiric magnetic wave.
We achieved to maximize its property by laying down the powder evenly and parallelly on its base material which is made of special rubber of polyethylene.
