The Beeb Reslo

Xaudia have a limited number of Reslo RB microphones for sale, with upgrades and modifications inspired by the BBC. We call these "The Beeb."

'The Beeb'.  Modified Reslo microphones by Xaudia

Back in the 1950s and 60s, the BBC published a number of R&D reports on ribbon microphones. Here's what they had to say about the humble Reslo RB...

It seemed possible, that a few simple modifications might result in an appreciable improvement in response..."

W. Manson and T. Somerville, BBC R&D Report No. L044, 1961

They recommended a number of modifications, which included....

• Swapping the transformer to one with higher primary inductance,
• Conversion from 50 ohm to 300 ohm output,
• Fitting a more open interior mesh,
• Removing the cloth around the ribbon motor,
• And reversing the motor assembly so that the ribbon element is at the front.

Xaudia have recreated these mods and added a few more of our own. "The Beeb" has an XLR output, and new 1.8 micrometer ribbon. We also ultrasonically clean these before re-assembly to remove 50 years of gunk. And we put a (removable) sticker on them, so you know that they are 300 ohm mics.

Reslos with XLR upgrade

We have a very limited number of these mics for sale. Alternatively we can upgrade your own mic to these specifications. Please get in touch for details.
