Wireless 2-Channel Receiver Omnitronic FAS TWO 660–690 MHz — rack-mountable audio receiver

Omnitronic FAS TWO is a rack-mountable 2-channel wireless audio receiver operating in the 660–690 MHz band. It receives two independent audio channels for microphones or instruments and is engineered for live sound, events, and fixed installations where stable RF reception and convenient rack integration are required. The receiver provides separate audio outputs for each channel and a front-panel display for status monitoring, designed to work as part of PA systems and small to medium venue setups.

Advantages

The unit offers dual-channel reception within the specified 660–690 MHz frequency range, enabling simultaneous use of two wireless transmitters with independent audio paths. Rack-mount compatibility allows straightforward integration into standard audio racks and stage systems. Built for reliable RF performance, it reduces dropouts and interference in typical live and installed environments. Separate outputs and clear front-panel indications simplify setup and channel management.

Suitable for

• Live performances and stage presentations

How to use

Install the receiver into a standard 19" rack using the provided mounting brackets and secure power and audio connections. Match each wireless transmitter to one of the receiver’s channels by setting the corresponding frequency within the 660–690 MHz band and confirming a stable RF link via the front-panel indicators. Route the channel outputs to the mixer or power amplifier, adjust audio levels at the receiver or mixing console, and perform a sound check to verify signal clarity and absence of interference.

Usage recommendations

Place the receiver in a well-ventilated rack location and maintain line-of-sight where practical between transmitters and the receiver antennas. Avoid placing the unit near strong RF sources or large metal obstructions. For multi-device setups, scan the usable frequencies within 660–690 MHz to select the cleanest channels, and perform routine checks of transmitter battery levels and audio gain to ensure consistent performance.
