Grab. Go. Jam

The compact and lightweight VX series is joined by a new 50W model, specialized for keyboard and featuring Nutube, the new vacuum tube. With a coaxial speaker that outputs clear sound even to the high-frequency range, and a bass reflex structure that reproduces rich low-frequency sound with ample power, this amp delivers high-quality sound from a compact and lightweight unit. The three-channel design provides an independent volume control for each channel, and CH3 also supports mic input.

Lightweight and Durable

The Vox VX50 KB keyboard amplifier is built with a focus on durability and portability. Its lightweight, sealed ABS body ensures robustness while keeping the amp easy to transport. This construction ensures reliable performance and longevity, making it suitable for both studio and stage use.

Back Panel

The back of the Vox VX50 KB keyboard amplifier is designed for user-friendly functionality and optimal performance.

Additionally, there’s a footswitch input for seamless integration with a compatible footswitch, enabling hands-free control of the amp’s versatile features.

Shape Your Sound

VX50KB

The three-band master EQ with BASS, MIDDLE, and TREBLE controls is common to the three channels. It provides basic and flexible control that you need to shape your sound.

■ Revolutionarily lightweight and compact, with high 50W output

In spite of its high 50W of output power, the lightweight 4.1 kg (9lbs) body and compact design mean that transportation is easy. The one-piece ABS chassis ensures high durability and great sound quality while keeping the weight light.

■ The warm vacuum tube sound of Nutube

By using Nutube, the new vacuum tube, this amp achieves an output power of 50W while being compact, lightweight, and power-efficient. In addition to enjoying the rich overtones and sonic power of vacuum tubes, you’ll also appreciate the clear tone with compression that particularly enhances piano and electric piano sounds.

■ Coaxial speaker provides clear output extending to the high-frequency range

The coaxial two-way speaker features a powerful eight-inch speaker plus tweeter. From a bountiful low range to clear highs, the output is transparent-sounding while ensuring a sense of volume. Another major advantage is the excellent sense of positioning that you receive from the VX50’s coaxial speaker. Even the sparkling highs of a piano or synthesizer will be expressed in every detail.

■ Bass reflex structure provides ample output power and rich low-frequency reproduction

A proprietary, optimized bass reflex structure is used, with every detail adjusted specifically for the response of keyboard instruments. The chassis uses ABS polymer for its light weight, durability, and excellent acoustic properties. This allows for a 3D design that would be impossible with wooden material and achieves the ideal cabinet resonance. In addition, wood is used for the baffle, achieving the optimal resonance for a keyboard amp. While the chassis is polymer, a distinctive sense of high quality is emanated by the stony-finish exterior and a white/black color scheme based on a keyboard motif.

■A rich array of input/output jacks

This unit’s three-channel design meets the needs of any scene: three keyboards, two keyboards and a mic, or a stereo keyboard output plus a mic. It can also act as a simple PA system. In addition to a master volume, independent volume controls are also provided for each channel 1–3. Furthermore, each channel also has a CLIP indicator to prevent distortion caused by excessive volume. CH3 is also equipped with a PHASE switch. When a mic is connected to CH3, this switch can be used to correct phase interference with instruments that are connected to CH1 and CH2 or to reduce low-frequency acoustic feedback. A full complement of input/output jacks are also provided, including an AUX IN jack for connecting your audio player or rhythm machine to enjoy jam sessions, a LINE OUT jack that can be used for connection to a PA system, and a headphone jack that’s ideal for practicing at home.

Sonido nitido, tanto si reproduces sonido de piano acustico (gran piano 88) como si reproduces sonidos de piano electrico u Organo a este ultimo le añades sonido Leslie y si es un buen efecto casi sientes el rotaorio...bueno para cualquier espacio..si la sala es grande que te conecten a traves de linea, pero con el sonido del VOX.

I have almost no experience with amps so wasn't sure what to expect. The sound quality is not good and somehow it creates areas in front/center of amp where the sound gets super focused and it forces them to move. It gives off a tinny noise (cheap) except it wasn't cheap!! For the same money I could have bought a nice Roland but now I'm stuck with this terrible amp. Steer clear. I will never buy another amp if I haven't heard it in action.

I was surprised that the materials were kinda cheap and looks somewhat toy-like. However, the sound quality is good for a practice amp and it's lightweight and vert portable.

Amp produces nice sound, not huge but enough. I don’t want to lug a heavy amp around with me.

I used the Vox keyboard amp I just purchased through Amazon just the morning at church. Needless to say, I was very very surprised at how well it performed. We presently don’t have a large forum and meet in a meeting hall and this is just perfect for that kind of set up. It only weighs 8 pounds and has more sound than I originally thought I needed. I’m extremely impressed that it works so well for being so I small and light weight!

As a busy working musician, I was looking for a lightweight keyboard amp that I could take to rehearsals and smaller gigs. This one has really done the trick.At 50 watts, it’s plenty loud for practice and most small venues that I’ve been at. I even was able to use it as a personal monitor at a couple larger rooms, and it worked out really well.Because it’s only an 8” speaker, I wouldn’t recommend trying to use it in a large ensemble/large room without the aid of the PA or a second amp, but that’s where the line out jack comes in handy.Love the sound, functionality, and portability of this unit!

This is an amazing amp! I use it for live performances with a large rock band and it is loud! The sound quality is maintained even at the loudest volume, the channel volume controls are really useful, and the EQ is simple but perfect. The simplicity of the controls makes it easy to use when you're in a hurry. The amp is very lightweight and portable, but I carry mine around in a leather suitcase to keep it from getting scuffed or damaged.

I really wanted this to work for me. Looks great. Very light. Perfect size. But it just doesn’t sound that good. I compared it head to head with a Fishman Loudbox Mini using a piano sound module and the Fishman blows it away. I think the 50 watt power rating is, let’s say, aspirational.

Great price, great sound and especially a light weight!!!! I was really taken by surprise on the quality and the tone it delivered. I would recommend to every keyboardist to buy one of these awesome amps for your Arsenal

Love this. I bought as a smallish amp-speaker for a stage piano (it's marketed purpose). I can't comment on that yet, as awaiting some cables. However, I've plugged in an mp3 player through the aux input. Lovely clear sound in mono to rival my Denon system with Q speakers. Looks retro-cool and really light.
