The RF Venue Spectrum Recorder, a compact and self-contained device, simplifies monitoring and optimizing wireless microphone and in-ear monitor systems. It continuously captures RF activity in the 400-700 MHz band, saving data as time-stamped CSV files on its internal storage. These files can be retrieved directly via USB drive or accessed remotely over a local network.

Connect Spectrum Recorder directly to your wireless microphone antenna system or use the included whip antenna to capture spectrum for a site survey before your system is installed or loaded-in. PoE capable and battery ready, the Spectrum Recorder is small and lightweight enough to easily ship to a remote location or deploy across many rooms on a fixed installation.

Spectrum Recorder's data can be uploaded to RF Venue's free web-based Wireless System Builder tool for system design and frequency coordination, or imported natively to third party software like Shure® Wireless Workbench and Audio-Technica® Wireless Manager. No software installation is needed, and no cloud subscriptions are required for Spectrum Recorder.

Automatic Spectrum Recording: Instant and continuous capture of spectrum activity from 400-700 MHz. No spectrum analyzer or complex test equipment required.

24 Hour Scan Data Capture: See the entire scope of spectrum activity over 24 hours. Max Hold and Average scan views are captured and calculated automatically.

Active Frequencies Scan: Separate fixed transmitters such as DTV stations from surprise interference sources. The Active Scan compiles hard to detect frequencies to help protect your wireless system from interference hits.

Power Over Ethernet (PoE) Capable: Deploy Spectrum Recorder where needed with just an ethernet connection. Easily cover multiple rooms, buildings, or studios with your own network of LAN-based Spectrum Recorders.

Battery Power Ready: No power? No problem. Spectrum Recorder's 5V USB-C DC power input can accommodate common portable power banks used for charging mobile devices. A 10,000 mAh battery can power Spectrum Recorder for several days.

No Software Installed, No Subscription Fees: Spectrum Recorder does not require any outside services or onsite software installation. IT professionals can use the Spectrum Recorder MAC address to assign a fixed IP address via the network’s router if desired.

Updates and Upgrades: Look for exciting new capabilities for the RF Venue Spectrum Recorder as it grows and develops into the primary hub for all your RF spectrum data.
