Audio technica AT8539
The 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 (wireless microphone with model number ending in a cW); its output is a standard 3-pin XLRM-type connector.
It offers a low-cut flter to help minimize the pickup of unwanted low frequencies. To engage the low-cut flter, 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.
