Cello Bridge Dyna-Mic


RMacoustics brand new Cello Bridge Dyna-Mic is a patent pending, dual function Microphone/Pickup System. A unique violoncello clip-on microphone system, that enjoys some of best pickup’s benefits and captures both air vibrations as well as full instrument’s wood/body vibrations and resonances. As a result, it can reproduce a clear, well detailed, and remarkably loud, amplified tone that simply is indistinguishable from instrument’s natural sound. Use it as a stand alone cello microphone, as a contactless sensor (aka cello pickup) to hear more wood tone of your instrument or simply blend both “air” or “wood”, at any percentage. That is to say, you can have any sound you like from totally natural tone to a solid, wood tone, with great attack and response. No contact to bridge or soundboard. Clip-on installation in just a couple of seconds.

Usually ships within 2-5 days. If that’s not the case, a notification will be sent accordingly.

– Cello Bridge Dyna-Mic clip-on microphone/pickup system that senses cello’s both, air and wood vibrations.

– Multiple source system comprises a microphone and pulse sensors to also capture bridge and soundboard vibrations.

– Virtually no installation, as it mounts on cello rib in just a few seconds.

– Above all, there is absolutely no contact to bridge or soundboard. As a result, violoncello “breaths” naturally and nothing bothers natural sound to make it’s way out of it. Therefore, the system reproduces a clear, detailed, amplified tone that simply is indistinguishable from instrument’s natural sound.

Totally removable.

– No need for instrument modifications or alterations.

– Cello natural sound unaffected.

Adjustable tonal characteristics. From mellow, dark sound with full resonances and rich harmonics,  to bright more focused sound with less resonance and “cut through mix” characteristics, all with excellent attack and response.

-This Cello Bridge Dyna-Mic has exceptionally feedback resistant in loud environments, so you can play way more loud, than by using a conventional microphone.

– Virtually no additional weight on the instrument.

– Easily interchangeable between different instruments. In other words, you can use it with as many instruments as you have.

– Belt pack preamplifier.

I had heard about RMacoustics, but never had the opportunity to test any of their gear. It was a pleasant surprise for me, when they kindly asked me to demonstrate Bridge Dynamic, their brand new Cello Microphone system and I was really curious about this, especially after a small conversation we had. In just a couple of seconds they installed it on my cello, without any alterations, which was totally reassuring for me. It was just a clip on my cello’s rib, nor touching the bridge or the soundboard of the instrument. So, no changes to instrument voice. But the real surprise was the first notes I played. The room was full of rich, warm, natural cello sound. As I was continued to play those demo pieces, I felt like I didn’t want to stop playing. Congrats to RMacoustics for a very promising product!! And as for removing it… In reality a matter of two seconds. (Click here to find out more for Ioannis Stefos)
