Product Description

Behringer K900FX, Keyboard / PA Amplifier

With 90 Watts of power it should be a challenge to reach its performance limits! This 3-channel PA / keyboard amplifier in a bass reflex housing has a powerful original 12 ”BUGERA ™ speaker and a specially developed 1” tweeter for a clear, unadulterated sound - perfect for your gigs.

An internal 24-bit effects processor is on board and offers 100 presets such as reverb, chorus, flanger, delay, pitch shifter and various multi-effects. Our groundbreaking FBQ feedback detection shows feedback frequencies instantly, making it easy for you to avoid feedback problems.

In addition, the K900FX offers complete 3-channel operation with separate volume control and one FX Send connection per channel as well as an additional XLR microphone input (channel 1) for direct connection of dynamic microphones. An integrated 5-band graphic EQ gives your sound the finishing touch.

Frequently Asked Questions

The Roland amps will have noticeably better clarity and a more refined sound, but the K900FX gets you 80% of the functionality for a significantly lower price.
The effects are serviceable for basic reverb or chorus, but don’t expect professional-grade quality; external effects pedals will always be preferable for serious tone shaping.
It’s usable for acoustic guitar, especially with the mic input, but the EQ isn’t optimized for acoustic instruments – you’ll want a dedicated acoustic amp for the best results.
