RT1 - Ribbon Tube

The Tube Ribbon is one of the first of its kind.

Launched in early 2006 as a prototype it was the world’s first Ribbon mic with a tube.

It builds on the hugely successful sE Ribbon, considered one of the best mics in it’s class, and used in Pro Studios the world over, but adds a silky warmth to the ‘standard’ sE Ribbon sound.

It ships with full shock mount and black Aluminium flight case and sE mic cable and also comes with a limited 10 year capsule replacement warranty.

The RT1 is ideally suited to recording electric guitar cabs, overhead drum mic-ing, brass and woodwind instruments, string sections and for commercial broadcast and voice-over.

Don't just take our word for it.



Future Music “RT1-Ribbon mic is an interesting and innovative move from sE, in the same way that their dual valve Gemini is. It’s not cheap, but then you wouldn’t expect it to be, would you? Excellent”
