RM-5 Mics Were Used to Record Cirque Du Soleil Album

RM-5 DIY Ribbon Mic Cirque Du Soleil Rob Heaney

RM-5 DIY Ribbon Mics were used as drum overheads and main electric guitar microphones in every track of the Kurios album by the famous Cirque Du Soleil.

You can listen to samples on Cirque Du Soleil web-site:

The album was recorded by Rob Heaney, a Canada-based music producer, multiple award winner, who have recorded and produced many of Cirque Du Soleil albums. Here’s what he has to say:

“All the [drum overhead] tracks were your mics only through a McCurdy class A tube mic pre from the 50’s. Also the accordion had one of your mics plus two tube mics. Electric guitars – 90% of the sound is your mic through a Trident B-range Console.”

“It’s truly my #1 choice for a Ribbon Mic and I have a healthy collection of all the Fav’s.”

RE-254 DIY Ribbon Mic Motor

Pre-Assembled Hand-Crafted RE-254 Ribbon Mic Motor

The RM-5 Ribbon Mic Kit comes with RE-254 microphone motor. The motor is our original design. The assembly and ribbon installation take place in our lab. Our dedicated microphone technician have been doing this job for several years with passion and attention.

RE-254 is a classical motor design with a long 2″ ribbon. The motor produces the warm old-school sound. Big ribbons are known for their bold tone with specific character no other microphone can provide. It is always nice to have such vintage touch in your palette.

The motor is available with either standard 2.5u ribbon or optional 1.8u ribbon upgrade. You can read about the differences here: Ribbon Microphone Foil – Thickness and Sound

RTX-35 DIY Ribbon Mic Transformer

Original Toroidal Output Transformer

Another major part of the RM-5 DIY Ribbon Mic Kit is the RTX-35 Toroidal Output Transformer. The transformer is a very important component in a ribbon microphone. It’s job is to lift the ultra-low voltage of a ribbon motor with the best possible sound quality.

We’ve designed the RTX-35 Transformer particularly for RE-254 Ribbon Motor. The transformer has a great gain/impedance balance to ensure the best performance. Because of the original design, these two parts make a perfect match with each other. The motor and the transformer work together as a single system.

By performing several blind tests, we’ve made sure that RTX-35 Transformer has the matching or better subjective sound quality comparing to well-known ribbon microphone transformers.

RM-5 DIY Ribbon Mic Body

Locally Machined Matt-Polished Stainless Steel Body

A local CNC plant individually machines the RM-5 DIY Ribbon Mic bodies. The metal specialists hand-select the stainless steel tubing of finest grades. The machinists make body units with the attention to the detail and mechanically matte-brush them for our signature appearance.

Our own original XLR receptacle is CNC carved right in the bottom cap. The male XLR insert with gold-plated pins is included.
