The ULTRATONE K900FX specializes in clean, powerful sound. With this 90-Watt workhorse in your rig, your keyboards will sound their best gig after gig.

Channel Your Sound

The K900FX gives you three channels, each with separate volume and FX SEND controls, plus Channel 1 has an additional XLR mic input for direct connection of a dynamic microphone. So, if you're the kind of keyboardist with multiple instruments at your disposal, the K900FX is ready to handle up to three independent signals. It is also ideal for use as an all-in-one solution for keys and vocal applications. The onboard 24-bit digital FX processor, with 100 amazing presets, adds a high-tech dash of reverb, chorus, flange, delay, pitch shift and other effects to your sound.

The MAIN Section gives you separate controls for FX RETURN, MASTER VOLUME, PHONES and SHAPE. A CD INPUT allows you to play recorded music through the K900FX during performance breaks, or just for playing along. A separate headphone output is perfect for quiet practicing. The K900FX also features an integrated 35-mm pole socket for stand mounting and use as a PA system.

Big, Beautiful BUGERA

A 12" BUGERA woofer, made completely in-house by our own skilled artisans, works in connection with a custom-made 1.0" driver for awesome, full-range sound. The K900FX also features a subwoofer output, as well as a line output for direct connection to your mixing console.

Be EQ'd and Feedback-Free

Use the K900FX to bring out the best in your sound via its 5-band graphic EQ with our proprietary FBQ Feedback Protection System. This incredible audio solution immediately pinpoints frequencies that cause feedback, so you get perfect sound every time.
