The compact and lightweight VX series amplifiers get exciting with the 50W model for keyboards: this amp also contains an innovative Nutube tube. The built-in coaxial loudspeaker ensures a perfectly defined sound even in the highest altitudes, while the bass reflex builds up a lot of pressure. Despite its compact size and featherweight, this amp is in every way a “big one”. The three input channels have separate volume controls, CH3 can be used as needed as a microphone input. Seen in this way, this amplifier can also effortlessly function as a portable sound system. On the input and output side, the amp comes with an AUX IN, a headphone and a LINE OUT jack for direct connection to the sound system..

Revolutionary, lightweight and compact – despite 50W performance

Despite its output power of 50W, this amplifier is in a 4.1 kg lightweight and compact housing – the transport runs accordingly relaxed. The one-piece ABS chassis is virtually atomic bomb-proof and at the same time contributes decisively to the outstanding sound.

The warm tube sound of Nutube

Thanks to the innovative Nutube tube, this amplifier offers an output power of 50W despite its compact size and efficient use of energy. This approach guarantees the overtone structure typical of tubes and a clear sound with the kind of sound compression that gives piano and E. piano sounds the necessary bite.

Coaxial loudspeaker for a defined transmission with a filigree height range

The 2-way coaxial speaker includes a punchy 8 “woofer and a tweeter and transmits not only a rich bass range but also delicate heights: its sound is always transparent, but this is never at the expense of sound pressure. Another advantage of the VX50 is the excellent sound localization, which can only be achieved with a coaxial arrangement. Even the glittering heights of piano and synthesizer sounds are reproduced without compromise.

Bass reflex construction for more pressure and a rich bass range

The specially developed bass reflex design has been specially adapted to the reinforcement of keyboards. The housing is made of ABS polymer, which is feather-light, but also has excellent acoustic properties. In addition, this material allows the use of a 3D design that can not be implemented with wood – here are the ideal cabinet resonances virtually pre-programmed. The baffle is still made of wood, because this material gives the amplified sound the ideal finish. And although the case is made of polymer, the stone look with its white / black color creates a high-quality impression and is clearly reminiscent of a keyboard.

Numerous input and output options.

The 3-channel design of this amplifier is suitable for many applications: two keyboards, two keyboards and a microphone or a stereo keyboard and a microphone. In addition, the amp can be used as a compact sound system. In addition to the MASTER control, it provides separate volume controls for channels 1 ~ 3. All channels are equipped with a CLIP indicator to avoid distortion. CH3 also has a PHASE switch. If you connect a microphone to CH3, this switch avoids feedback if the microphone is in front of the amplifier and thus also picks up the signals from CH1 and CH2. An audio player or jamming drum machine can be connected to the AUX IN jack, while the LINE OUT jack allows direct connection to the PA system.
