Product Overview

The Williams Sound WCA 105 is a 4-inch audio adapter cable that converts a female RCA connector to a Mini-Phoenix Contact connector, used to send audio to the Williams Sound WIR TX75 PRO (C or D) infrared transmitter. This short adapter cable bridges the connection between RCA-output audio sources and the Phoenix Contact input on the WIR TX75 PRO, providing a clean single-channel audio feed without the need for custom field-wired connectors. It is a direct-fit accessory for WIR TX75 PRO C and D transmitter installations.

Product Description

The WCA 105 serves as a signal conversion adapter between an RCA source output and the Mini-Phoenix Contact audio input on the WIR TX75 PRO C and D infrared transmitter series. In commercial AV installations where an analog audio source such as a mixer output, audio processor, or media player provides an RCA output, the WCA 105 allows that signal to feed the WIR TX75 PRO transmitter without custom soldering or in-field Phoenix Contact termination. The two-conductor coaxial cable construction maintains signal integrity for the short 4-inch run between the RCA source and the transmitter input block. The cable is factory-terminated at both ends for immediate deployment. The Mini-Phoenix Contact connector mates directly with the WIR TX75 PRO input terminal, and the female RCA end accepts the standard male RCA plug from the source device. The 4-inch length is optimized for close-proximity connections where the RCA source is adjacent to or rack-mounted near the transmitter.
