The core of Panasonic's SR200P 1.9 GHz Digital Wireless Microphone system, the WX-SR204 digital wireless receiver supports four wireless microphone channels (choose between Panasonic's WXST200 handheld mics and/or WX-ST400 lavalier mic + wireless bodypacks). Perfect for classrooms, conference rooms, auditoriums, museums, or even bars/ restaurants, the WX-SR204 features RJ45 (CAT5 / CAT5e / CAT6) connections up to eight (8) external antennas (WX-SA250), an RJ45 connection for an optional expansion receiver, and an ethernet network connection for easy integration with third party control systems such as Crestron, Extron, Q-SYS and others. LEDs on the front panel show the system status during startup & microphone pairing, antenna status during operation, and an LED indicator of when the receiver is being controlled remotely. Secure Euroblock connectors for independent channel outputs, external audio input and a mix output provide peace of mind that they will not detach easily in any type of installation. Ships with rack ears for easy rack mount installation.
