The Audio Technica AT8539 power module allows any Audio Technica Wireless Essentials microphone to operate as a wired microphone.

The power module's HRS-type 4-pin input connector mates with any Audio Technica Wireless Essentials with its output being a standard 3-pin XLRM-type connector.

It offers a low-cut filter to help minimize the pickup of unwanted low frequencies. To engage the low-cut filter, use the end tip of a paperclip or other small pointed instrument to slide the switch toward the "bent" line.

The power module is constructed of rugged steel for maximum durability and optimum shielding from hum. A snap-on belt clip is included.
