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.
