U853PM & U853PMW

Connect the TA3F-type connector from the microphone's cable to the TA3M- type connector in the power module plate.

Note: Audio-Technica has developed a special RFI-shielding mechanism that is an integral part of the connectors in the UniPoint® line. If you remove or incorrectly replace the connector, you may adversely affect the unit's RFI immunity. Audio-Technica offers a crimp tool (ATCT) and RFI shields that enable you to shorten the cable and correctly reinstall the connector while maintaining the highest level of RFI immunity.

If you need to shorten the cable between the microphone and power module, it can be done two ways:

a. To maintain original RFI shielding (see note above), the TA3F-type connector can be removed from the cable end, the cable shortened and the connector replaced using Audio-Technica's available crimp tool and RFI shield for TA3F- type connector.

b. If RFI immunity is not required, the TA3M-type connector on the plate can be removed and discarded (save the back nut and washer). Assemble the included plastic ferrule into the hole left from the TA3M-type connector, using the washer and nut from the connector to secure the ferrule. Cut the cable to the desired length plus a few inches. Thread the cable through the ferrule and tie a knot in the cable behind the ferrule to secure it. Carefully strip the ends of the cable and connect the wires to the terminals formerly occupied by the TA3M-type connector. Maintain color coding (Shield - S, Yellow - Y, Red - R) and connect the microphone wires to the appropriate terminal screws (Fig. 3). Note: The cable has two red wires and two yellow wires. Twist the two red wires together and the two yellow wires together (Fig. 4).

Avoid leaving the microphone in the open sun or in areas where temperatures exceed 110° F (43° C) for extended periods. Extremely high humidity should also be avoided.
