The EV QuickSmart Mobile app is the official app from Electro-Voice for mobile device control of portable loudspeakers.

EV QuickSmart Mobile is an essential tool for simultaneously configuring, controlling, and monitoring up to 6 ELX200 Series portable loudspeakers. Using BLE connectivity, you can adjust EQ settings, gain, preset, and crossover parameters while in front of your PA system. 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.

With EV QuickSmart Mobile, you can now take full control of your system with your phone or tablet. Control your sound from where you are, not where the knob is!

Okay for version 1, but needs work.

I know this is a new feature/app, and I’m sure it’s a work in progress, but it needs some serious improvement. If you update anything at all, it must have a decibel number readout for the volume sliders and the ability to link pairs of speakers together within a complete setup, so you can adjust subs and tops separately. Also, the app is very easily confused and often doesn’t control the whole system volume consistently. Lastly, if you walk out of range, it “forgets” your settings and has no idea where you left the levels. Also, the peak warning doesn’t work for me unless I have the app open. Long story short, it’s okay dialing in the system at the start of the night...that’s it.

No Security. Anyone can Hijack.

Great idea in theory, but there is nothing preventing anyone who has the App from connecting and controlling your speakers.

The only prevention that I can see is that only one session at a time is allowed. If you quit the app or it backgrounds, then someone else can discover your setup and control it thereby locking you out.

Best to turn the control feature off until they update their products with something that allows pairing for the Control portion of the app. My Evolve 50’s do have pairing but only on the Audio streaming side.

Sure, it’s a good start. But is rather limited in what you can do, why can’t you turn up individual inputs and “mix”? Still have to go to back of speaker to change most major settings (sub level) all should be controllable within the app.
