Description
This is a genuine Crown-made PZM microphone designed for permanent mounting. It can be recessed into a wall or ceiling or mounted on a board and made portable. Unlike the old Tandy PZM mics, the Crown 20R is phantom-powered and requires no batteries
These are ideal for ambience, drum room, or as a general purpose listen mic, but PZMs work extremely well as close mics. I’ve used them in the past taped to the underside of a piano lid, taped to the studio glass for a horn section and taped to the wall behind a drummer
Pressure Zone Microphones caused a stir in the 1980s but seem to have sunk without trace since. Crown have been making them since the 80s and, for a short while, Tandy (Radio Shack) sold a cheap version under licence. Nowadays Crown, Audio Technica, Sennheiser & others produce PZM mics for many uses
A Pressure Zone Microphone places the capsule adjacent to a boundary to pickup pressure waves. They normally have a small capsule placed opposite a flat plate, the size of the plate determining the low frequency response. When taped to a wall or floor, a PZM can give remarkable results, particularly in small rooms. They are also superb taped to the underside of the piano lid on grand pianos
Placing the PZM flush with the reflective boundary means that reflected sound (room ambience, etc) does not interfere with the direct sound. As a result a PZM will sound very different to a conventional microphone in a small room
PZMs punch well above their weight and are a great addition to any mic cupboard. My advice is to have a pair setup permanently to capture spur-of-the-moment ideas – tape them to a wall or to a sheet of perspex on a mic stand
Phantom-powered condensor mic with a balanced output on terminal strip. Supplied with a balanced XLR output cable. Tested & working 100%.Photos show the mic for sale
