RF Venue 4-Zone

Expand Your Wireless Microphone System's Coverage

4 ZONE provides individual channel RF signal attenuation control down to -31dB in 1 dB steps, allowing you to fine-tune the RF levels in each coverage area. It also features selectable 12V DC power over coax, which is good for active antennas or in-line amplifiers.

The 4 ZONE has selectable on/off inputs, allowing for quick control of the wireless microphone coverage zones for roaming transmitters. In addition, you can easily choose which zones are active as a live event or location sound project progresses, saving you setup and breakdown time on site.
