Specification: element: φ34 mm pressure gradient transducer gold-plating: single-sided polar pattern: uni-directional frequency response: 20hz-20khz sensitivity: -38db±3db (0db=1v/pa at 1khz) equivalent noise level: ≤15db a max.Input spl: 138db (at 1khz ≤1% t.h.d) power anode element: 28v-60v

Application:

Used for making condenser microphones and electronic tube microphones

Important Usage Notes for Gold‑Plated Capsules:

Do not touch the internal diaphragm. Handle only by the metal backplate.

Protect from moisture. When not in use, store the microphone in a sealed container in a relatively dry environment.

A preamp circuit board is required. The capsule needs a polarization voltage between 3V‑70V provided by a preamp board. Connecting it directly without a preamp will produce no sound.

1pc 34mm capsule with box packing

Application:

Accessories for DIY condenser microphone, repair microphone, or upgrade mic.
