Weighing 18 pounds (8kg), it measures 11.46L X 10.4 W X 15.71 H-inches and has a comfortable carrying handle. It operates either standing vertically or on its side--like a stage monitor wedge. There is also a standard socket for pole mounting and, in any position, the controls are easy to see and work. But the free App is the best way to fully control your JBL EON ONE Compact with all controls 'mirrored' on my device's screen.

The App gives access to all four inputs--each has a four-band parametric equalizer in addition to both low and high frequency shelving equalizers. The first two input channels have Combo XLR jacks for either TRS line or microphone inputs and within the App, you may make those channels either line or mic inputs with fader levels shown on the App screen. Love it!

There is also phantom powering on/off for Channel 1 while Channel 3 has a dedicated 1/4-inch line input for playing backing tracks, and Channel 4 is switchable between a Bluetooth audio feed (from your device) or an 1/8-inch TRS input jack for playing stereo audio from non-BT devices.

Channel 4 also has the Duck feature that automatically "dims" or lowers the volume of whatever audio program you have coming in to it whenever either input Channels 1 and/or 2 are active. With this version, you cannot adjust it at all but a future firmware update will allow full control. A great use of the Duck feature is to lower the volume of background music when narrating a live Power Point presentation.

Lastly, there is a 1/8-inch headphone jack plus a 1/4-inch pass-thru jack to "daisy-chain" as many Compacts as required or run two of them in stereo mode. Bluetooth audio can stream up to four Compacts.

I found the App to work great for setting up effects. On the FX page, Channels 1, 2, and 3 have individual send controls to add reverb, delay and a chorus effect in any amount. I also found the very professional 8-band EQ-Out Master equalizer for achieving a specific, finished sound. The App also has Snapshots you may store all your settings. For a traveling musician or presenter who has regular gigs at various locations, this is an awesome plus for storing settings to get going quickly and sounding great from the beginning of the gig. No sound check required!

I think this is an excellent and worthwhile personal PA system. JBL has thought of every possible way it can be used and designed this entire system and put it into an easy to carry, diminutive package. The JBL EON ONE Compact sells for $549 MAP.
