CM20
Common name: Hebden Sound CM20
Production Status: Discontinued / Vintage
The CM20 is a Panel-mounting microphone with a bass roll-off cardioid response and electronically balanced output. Although intended as a TB microphone it is essentially a high quality studio capacitor design and may well be used for other more demanding purposes. 48V phantom power is required for full output but it may be operated at reduced performance from supplies as low as 12V. It is available with different lengths of gooseneck as the CM21 and CM22.
