The D500X external microphone can be used in applications requiring the microphone to be located at some distance from the D500X ultrasound detector. The microphone comes with a 1 m cable to be plugged into the external microphone jack of the D500X and a detachable horn, which can be used for increased directionality and sensitivity. It also serves to protect the microphone from rain. To remove the horn, pull it straight off the tip of the microphone.
The cable length can be increased up to 100 m using standard 5-pole XLR/DMX extension cables (two pair, shielded).
