Microphone No. 0005

AODIO Mic No. 0005 — Hand-Built Cardioid Condenser Microphone

Mic No. 0005 is part of the first production run of AODIO microphones — individually built, tested, and tuned by hand in Los Angeles.

Inspired by the classic transformer-coupled FET condenser microphones that shaped decades of records, each AODIO microphone is built one at a time using carefully selected components, including a Fairchild JFET at the heart of the amplifier circuit.

Rather than simply assembling a collection of parts, every microphone is individually biased and tested before it leaves the bench.

Built One at a Time

These microphones aren’t mass produced.

Each microphone is assembled, biased, measured, listened to, and finished individually. Small variations between components mean every microphone gets its own final testing rather than relying solely on the specifications of the design.

Your microphone will include its individual test documentation and Letter of Authenticity.

PRESALE — Please Read

Mic No. 0005 is being offered as a presale.

Your purchase reserves this specific serial number and funds the final components required to complete the microphone.

Please allow approximately 2–3 weeks for assembly, testing, and fulfillment.

Each presale microphone will be completed with a new capsule and transformer, individually biased and tested, and shipped only after it passes final QC.

One microphone. One serial number. Built for one owner.
