broadcast & production microphones
AT8004
Omnidirectional Dynamic Handheld Microphone
Features
- Ideal for interviews, sports broadcasting and as the “mono” mic when used in conjunction with a stereo microphone
- Omnidirectional polar pattern provides natural reproduction of surrounding ambience
- Rugged housing with hardened-steel grille stands up to field use
- Internal shock mounting minimizes handling and cable noise
Descripton
The AT8004 is a dynamic microphone with an omnidirectional polar pattern. It is designed for on-location interviews/sports broadcasting.
The microphone’s omnidirectional polar pattern is ideal for reproduction of surrounding ambience.
The output of the microphone is a 3-pin XLRM-type connector.
The microphone is enclosed in a rugged housing. The included AT8405a stand clamp permits mounting on any microphone stand with 5/8″-27 threads. A soft protective pouch is also included.
Operation and Maintenance
Output is low impedance (Lo-Z) balanced. The signal appears across Pins 2 and 3; Pin 1 is ground (shield). Output phase is “Pin 2 hot”— positive acoustic pressure produces positive voltage at Pin 2.
To avoid phase cancellation and poor sound, all mic cables must be wired consistently: Pin 1-to-Pin 1, etc. For a high-impedance (Hi-Z) mic input, connect a Lo-Z balanced cable to a Hi-Z matching transformer at the equipment input.
Take care to keep foreign particles from entering the windscreen. An accumulation of iron or steel filings on the diaphragm, and/or foreign material in the windscreen’s mesh surface, can degrade performance.
