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 on up to 6 Bluetooth™ equipped EV portable loudspeakers Including ELX200 series, EVOLVE 50, EVOLVE 30M & EVOLVE 50M. 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 & EVOLVE 50M. 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!

Useless App For Metra ,

Needs Signal Levels and Other Features Common to Digital Mixers

This app is a good starting point, but it’s not fully-baked. When used to control the Evolve 30M, which is marketed as one of your top new products, there are numerous basic features missing, including some that are visible on the PA amp/mixer panel interface itself, such as the levels for each channel. Also, connectivity when the app is minimized is poor and I often find myself searching for and reconnecting to the speaker after switching apps. Please take some time in the next app iteration and Evolve 30M firmware update to provide more digital mixer basics/controls, your current customers will appreciate it and potential future customers will know that Electro-Voice is committed to its products and their long-term use.

OK but lacking

I have the ev200s. It has 2 inputs plus the aux input. It would be great if this app allowed individual control (vol, eq) for each input. So if I had a mic in Input 1 and music in either the aux or Input 2 , I could mix them from the app. This app only allows vol and eq for the speaker itself. When could you add these features into this app?

Thanks for the feedback. We have shared this with our product team. At this time, a digital mixer is featured on our EVOLVE 30M and 50M systems.


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.
