EV QuickSmart Mobile is an essential tool for simultaneously configuring, controlling, and monitoring on up to 6 ELX200 Series Bluetooth™ equipped EV portable loudspeakers Including ELX200 series, EVOLVE 50 & EVOLVE 30M. Using BLE connectivity, you can adjust EQ settings, gain, preset, and crossover parameters while in front of your PA system. You can even mix your entire show on the fly from your device with mixer equipped speakers like EVOLVE 30M. Have peace of mind knowing that you are treating your system well during a performance with signal and limiter status indicators, as well as notifications for loss on connection and input clip events. Make quick adjustments to multiple speakers at once with dynamic component grouping, and locate your speakers in a dark show room with LED identification.
