Description

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 lter to help minimize the pickup of unwanted low

frequencies. To engage the low-cut lter, 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.

Architect’s and Engineer’s Specications

The in-line power module shall allow any Audio-Technica wireless

microphone terminated with a 4-pin HRS-type connectors to connect

to a wired microphone circuit. The input connection shall be through an

HRS-type 4-pin connector. Output shall be a standard 3-pin XLRM-type

connector. The power module shall convert the audio signal to a standard

balanced line microphone level output as well as provide operating DC

bias voltage for the attached microphone. An integral low-cut lter shall,

when engaged, roll off the low-end audio at 80 Hz with a slope of 18 dB

per octave. The lter shall be engaged via a recessed switch. The power

module shall be constructed of metal for optimum shielding from hum.

Output impedance shall be 250 ohms.
