Specification:

Model: K870 capsule

Product Name: K870 Capsule 34MM 4 Wires

Type: DC bias voltage

Voltage: DC25V-80V

Diameter: 34MM

High voltage: 12MM

Design reference sample: NEUMAN K870

Used for making and repairing condenser microphones, 4-wire can be used to make microphones with multiple directions. Replace and repair the old NEUMANN U87I capsule, which has perfect sound quality and does not produce excessive high frequencies.

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.

Packing:

1pc 34mm capsule+ stand

Application:

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