AKG GN15 ESP Microphone Module with CK31 Cardioid Capsule

Really good quality mics, I've used them on Vocals, acoustic guitar, overheads, toms, room, etc..

Only the capsule costs around £100 new.

Body Specs:

Proven reliability

The DAM Series GN ESP gooseneck modules for fixed and mobile installation features a programmable mute switch that can be set to various functions, e.g. on/off, push-to-talk or push-to-mute. Together with the clearly visible LED ring for MIC ON/OFF indication, the GN ESP modules can serve perfectly as a small-discussion system. The GN ESP gooseneck modules are available in three different lengths: 15cm (6in); 30cm (12in) and 50cm (20in). The electronic circuit design provides high immunity to radio-frequency interference. The gooseneck module fits all DAM Series capsules, CK31, CK32, CK33, CK47 and CK80, via highly reliable contacts.

Capsule Specs:

Proven reliability

The CK31 is a high-performance condenser microphone capsule with a wide cardioid polar pattern, especially designed for inexperienced speakers and applications where more than one person uses the microphone in turn. The CK31 capsule is integrated in a rugged metal housing and fits any mounting module of the DAM Series. To prevent contact problems, the capsule is equipped with large-area, self-cleaning, gold-plated contacts with deep threads to prevent misalignment and ensure extra-long life. The package includes a special two-part windscreen, which efficiently reduces wind and pop noise.
