• 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 ; Pi n 1 i s ground ( shiel d). Ou tput pha se is “Pi n 2 h ot” –
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
t ra n s f o r mer (Au d i o - Technica CP8201 or equal) at the equipment
input.
