With 90 Watts surging through 2 amazing 8" BUGERA dual-cone speakers, integrated FX and our revolutionary FBQ technology, this amp is the singer/songwriter’s best friend.

Sweet Stereo Operation

The ACX900 features a 90-Watt stereo amplifier with two dedicated input channels: one with a single ¼ " input jack for your instrument; and a second with a ¼ " input and XLR input – making it the ideal amp for a one-person show with an acoustic guitar and vocals.

Custom-Engineered Transducers

We never cut corners on our guitar speakers, and we never just pull what we have off the shelf. Our 8" BUGERA dual-cone speakers were designed specifically for the ULTRACOUSTIC Series amplifiers – it’s what sets us apart from the competition. When you buy an ULTRACOUSTIC ACX900 amplifier, you can rest assured that the speakers inside have been engineered to perform flawlessly with every other element for truly professional results.

World-Class FX & More

The ACX900 features a 24-Bit FX processor per channel with 16 incredible presets including world-class reverb, modulation, delay and a variety of effects combinations. We also include our F112 footswitch for remote activating and deactivating the effects processor on either channel. The instrument channel’s Phase switch makes it easy to eliminate the feedback commonly associated with acoustic guitar pickups, and each channel also has a Tuner switch that silences the speaker, allowing you to access a tuner connected to the handy rear panel jack.

Onboard 7-Band FBQ Equalizer

For more than 20 years, BEHRINGER has designed and manufactured some of the most successful FBQ Feedback Elimination processors. Now you can own and enjoy the benefits of this technology, as we have integrated the revolutionary FBQ Feedback Detection System in this product, so your sound system is completely feedback-free, allowing you to focus on your performance. Utilizing an ultra-fast feedback detection system, this ingenious circuitry helps you recognize and tame feedback frequencies immediately. When feedback is sensed in a specific frequency range, the LED on the associated EQ fader illuminates, showing you at a glance which fader to lower to overcome the feedback. That simple!

Each channel of the ACX900 features its own 7-band EQ equipped with our amazing FBQ Feedback Detection System for the ultimate in feedback elimination.

The Ins and Outs

On the back panel, you’ll find a stereo RCA Input for connecting a CD or mp3 player. If you’re just getting started as a guitarist, this is a great way to play along with your favorite tunes or backing tracks – or for providing pre-recorded music during your breaks. Two XLR Line Out jacks send your sound directly to a mixing board, and you can connect an external effects processor via the ¼ " Send and Return jacks for the Instrument and/or Mic channels.

Big Sound, Small Package

The ultra-portable ACX900 is the perfect way to bring a beautiful solo acoustic performance to your adoring fans. Plus, it’s an absolutely handsome piece of musical architecture!
