Expect flawless performance from the built-in panel antenna, plus a 150Hz - 7kHz frequency response and 1.9GHz frequency band operation, all working to ensure <1% distortion over line-of-sight distances of up to 1,300 feet. In addition to the Hollyvox app and webpage, you can configure group talk settings right from the unit itself. The Solidcom M1 Pro RRU Base Station offers ample interfacing onboard, including 2-/4-wire audio, USB, and RJ45, for both interfacing and powering the unit when not using NP-F battery power.
