Overview

Fully featured with PA capability.

The Behringer Ultratone K900FX keyboard amp delivers the power and connectivity gigging players need. With 90W of clean output through its 12" woofer and 1" tweeter, the K900FX projects your keyboard tones with authority. Its 3 channels give you flexible input options, with separate volume and FX send controls per channel. Plug in your keyboard, a dynamic mic and even another line-level source. Shape your sound with the 5-band EQ, then add rich effects using the built-in 24-bit digital FX processor. With 100 great presets like reverb, chorus, delay and more, your keyboard sounds will come alive on stage. For even more low-end thump, take advantage of the subwoofer output to add an external powered sub. The K900FX is also expandable—add more Ultratone amps to increase your system's power and coverage. Thoughtfully designed and gig-ready, the Behringer Ultratone K900FX puts excellent tone and flexibility within reach of keyboardists.

Project Your Sound Clearly With 90W of Power

The Behringer K900FX keyboard amp is ready to deliver your keyboard tones to the back of the room with its robust 90 watts of power. The 12" woofer reproduces lows and mids with authority, while the 1" tweeter adds crisp, detailed highs. Together, these transducers provide the full frequency response modern keyboardists need. The amp's power means you can easily cut through a live mix at rehearsal or keep up with a rock band on stage. Just plug in your keyboard, set your levels, shape your EQ and let the K900FX project your sound with confidence.

Shape Your Sound With Built-In FX and 5-Band EQ

Once you've got your keyboard amp producing plenty of clean power, it's time to dial in your signature sound. The K900FX gives you the tools, starting with its 5-band EQ. Boost or cut bass, midrange and treble frequencies to highlight the qualities you want. Cutting mids can help synths stand out in the mix, while boosting low mids adds body to organ tones. The built-in 24-bit digital FX processor opens up even more tonal possibilities with studio-grade effects. Choose from 100 presets like reverbs, choruses, flangers and more to add dimension. Use delay and pitch effects for cool solo passages. The K900FX makes it easy to shape the keyboard tones you need, whether practicing at home or rocking the stage.

Flexible Connectivity for Keyboards, Mics and More

With 3 input channels and flexible connectivity, the Behringer K900FX integrates seamlessly with the rest of your gear. Channel 1 features an XLR input with phantom power, perfect for adding a dynamic microphone to your setup. Channels 2 and 3 offer 1/4" inputs for your keyboard, drum machine, audio interface or another line-level source. Separate volume and FX send knobs for each channel allow you to fine-tune your mix. Add a powered subwoofer via the sub out for thundering low-end—great for EDM and hip hop. Two K900FX amps can be chained together as well, giving you more power and coverage for larger gigs. The possibilities are endless for crafting a system with the connectivity you need.
