Reverberating microphone
The plate moves with the acoustic sound in the room. Two microphones on the plate capture its decay, phase-coherent with the source. It is silent in the room; the sound exists only inside the microphones.
The instrument
A microphone built on a tensioned steel plate, in a hand-built oak cabinet. Two mics on the plate record the room. Choose the frame and grille, add the remote, and enquire to order.

How it works

The plate moves with the acoustic sound in the room. Two microphones on the plate capture its decay, phase-coherent with the source. It is silent in the room; the sound exists only inside the microphones.

Feed a line-level signal to the built-in transducer and amplifier. The plate is driven directly, the way a classic plate reverb works, and reads brighter and more focused than microphone mode.

Custom branding
AfterSound prints your studio logo onto the front sign, so the instrument reads as part of the room it lives in.



Two units
Run two Reverbophones and you hold two decays at the same time, a short room and a long one, on the same take. A single remote drives both.

Delivery
The Reverbophone ships assembled on a custom pallet, around 80 kg packed. AKA Acoustics handles freight and insurance to your studio, as the importer of record.
