AltoUber FX MKII Battery-Powered Portable PA Speaker With Digital Effects

Independent shopping perspective
The Korena take
Alto’s Uber FX MKII is a self-contained portable PA built around a five-speaker array and wide 320-degree horizontal coverage. Its 200-watt output is distributed through an 8-inch front woofer, two tweeters, and two side-firing drivers. Two independent XLR/TRS combo inputs accommodate microphones, instruments, or line-level sources, each with its own level control, two-band EQ, and digital effects; a 3.5 mm auxiliary input handles another playback source. Bluetooth 5.0 streaming, a rechargeable battery rated up to 100 hours, and a telescoping handle support untethered event setups.
Strong match
Who this is for
- Providing music and two independently controlled input sources at a park, backyard, or outdoor stage.
- Moving a self-contained PA to events where nearby AC power is unavailable.
- Creating a wireless stereo pair by linking a second unit over Bluetooth.
Consider the trade-offs
When to look elsewhere
- Events requiring more than two independently controlled XLR/TRS combo-jack input channels at once.
