General

The Ultratone K450K specialises in clear, powerful sound. With the help of this 45W workhorse, your keyboard will sound amazing, performance after performance.

The K450FX offers three channels, each with its own volume control and FX send controls, plus an extra XLR mic input on channel 1 for directly connecting a dynamic microphone. So if you're a keyboard player with multiple instruments at your disposal, then you can take advantage of the three independent signals of the K450FX! It's also ideal as an all-in-one amplifier for keys and vocals. The 24-bit digital effects processor is equipped with 100 stunning presets, and adds a high-tech sound to your keyboard with reverb, chorus, flange, delay, pitch shift and more.

The main section offers separate controls for FX Return, Master Volume, Phones and Shape. A CD input is also available for amplifying music with the K450FX during breaks, or for playing along. And if you want to practise in private, you can take advantage of the headphone jack. The K450FX is also equipped with a 35mm stand mount flange so it can be used as a PA system.

A 10-inch Bugera woofer, designed and produced completely by Behringer's own experienced technicians, works together with a custom-made 1-inch driver for a great full-range sound. The K450FX also has a subwoofer output, along with a line output for connecting your mixing console.

Use the K450FX and bring out the best in your sound with the 5-band graphic EQ, including Behringer's own FBQ feedback protection system. This audio solution detects direct frequencies that cause feedback, so you get the perfect sound every time.

Behringer Ultratone K450FX keyboard amplifier
Wrote the following about Behringer Ultratone K450FX keyboard amplifier
ik heb deze versterker ruim twee jaar geleden gekocht voor mijn theremin. Voor een theremin is een versterker nodig met een clean geluid en het geluid van een theremin heeft een echo nodig. Beide mogelijkheden heb ik in de K450FX gevonden. Inmiddels gebruik ik de K450FX ook voor mijn elektrische bas en mij electrische gitaar.

Ik heb alle inputmogelijkheden nu in gebruik:
- input 1 - XLR: hierop heb ik mijn bas aangesloten via een passieve DI-box. Mooi clean basgeluid
- input 1 - Jack: hierop heb ik mijn electrische gitaar aangesloten via de ART Tube MP USB voorversterker. In de ART Tube zit een buis dat zorgt voor een mooi helder en warm geluid.
De XLR- en Jackinput kunnen tegelijk gebruikt worden maar dat doe ik niet.
- input 2: hierop heb ik mijn theremin aangesloten.
- input 3: hierop heb ik mijn pc aangesloten. De pc krijgt het geluid dan van de ART Tube. Op de pc (linux) heb ik Guitarix en Rakarrack geïnstalleerd.

Op alle kanalen heb ik standaard de echo aanstaan: (nr. 27). Bij de theremin heb ik iets meer dan bij de andere aansluitingen.

Kortom, de K450FX is voor mij een alleskunner.

Sinds een paar dagen deze versterker in huis. Aangezien ik alleen thuis speel op mij 3 synths, gekozen voor de "kleinste" uit de serie.
Er zitten ruim voldoende ingangen op en ook de sub- en line-out zijn een prima aanvulling. Ondanks dat deze jongen "slechts" een vermogen heeft van 45W, komt er aardig wat geluid uit....Ook de 5-bands equalizer is erg goed. De effecten (welke per kanaal in te stellen zijn) gebruik ik niet want die zitten al op de synthesizers. Is wel leuk icm. gitaar/microfoon.
Wat mij een beetje tegenvalt is de geluidskwaliteit, een beetje "blikkerig" ondanks de equalizer. Dit komt waarschijnlijk door het ontbreken van een tweeter die bij de andere modellen wel aanwezig is.
Maar goed, via de line-out mijn oude versterker en bijbehorende speaker aangesloten en het klinkt een stuk beter. Bas tonen zijn echter vol en erg goed zonder kraken op hoog vermogen. Voor nog geen €150,- is dit zeker een prima aankoop en een zeer goede prijs-kwaliteit verhouding!
De service van BAX-Shop was uiteraard weer als vanouds: vertrouwd en uitstekend!

Vlotte levering, goede prijs-kwaliteisverhouding, verschillende betalingswijzen mogelijk,...! De versterker doet zoals beloofd in de beschrijving op de site. Over de duurzaamheid van het product kan ik natuurlijk nog niets kwijt, maar daar heb ik goede hoop op. Voorlopig zeer goede koop. Groeten uit Oost-Vlaanderen. Danny.
