Audio Technica AT8004L Specifications

OMNIDIRECTIONAL DYNAMIC MICROPHONE AT8004L WITH EXTENDED HANDLE

•Extended-length handle is ideal for on-location interviews and sports broadcasting

•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

Output from the microphone’s XLRM-type connector 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 (Audio-Technica CP8201 or equal) at the equipment input.

The microphone is RoHS compliant–free from all substances specified in the EU directive on hazardous substances.

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 surfa c e, can degra d e performance.
