Versatility Is The Key

Whether you have access to a mains power outlet or not, the Alto Uber FX can still deliver hours of clear, punchy, hi-fi sound from any source. With bluetooth and hard-wired capabilities, the number of applications this portable speaker is capable of is many and varied.

Built-In Effects

In addition to the awesome level of connectivity mentioned above, the Alto Uber FX also comes equipped with an Alesis FX engine. This engine hosts 15 high quality effects and a 2-band EQ, giving you complete control over the Uber FX's output.

Two Input Channels

Thanks to its two-channel design - each with independent Volume controls - you can directly stream your backing tracks from a mobile device into one channel, whilst your vocals are pumped through the other.

Fully Portable

In addition to be relatively lightweight - just over 11kg - the Alto Uber FX comes equipped with a pair of wheels and a retractable handle. This helps eliminate the inconvenience of having to carry the speaker if you are already carrying something: simply extend the handle, tilt the Uber FX, and away you go!

Whether you're a busking musician, a public speaker, or somebody looking to recite poetry in a coffee shop, the Alto Uber FX is perfect for you.
