About Vox VX50KB

If you're a musician seeking a compact, lightweight, and powerful amplifier, the VX50KB 50W Compact Keyboard Amplifier with Nutube is your perfect match. This innovative model from the VX series is specifically designed for keyboards, featuring Nutube technology for a warm, vacuum tube sound. Despite its compact size, this amplifier boasts a high 50W output power, making it a revolutionary addition to your musical gear.

The VX50KB amplifier is equipped with a coaxial speaker that delivers clear, high-frequency sound, and a bass reflex structure that ensures rich, low-frequency reproduction. This combination guarantees high-quality sound output from a lightweight unit. Its three-channel design provides an independent volume control for each channel, with CH3 also supporting mic input, making it versatile enough to function as a simple, easily transportable PA system.

The amplifier is designed with a full complement of input/output jacks, including an AUX IN jack for connecting your audio player or rhythm machine, a headphone jack for private practice sessions, and a LINE OUT jack for connection to a PA system. This makes it ideal for on-stage use as a monitor amp.

The VX50KB amplifier is not only powerful but also durable, with a one-piece ABS chassis ensuring high durability and excellent sound quality. Its Nutube technology allows for a clear tone with compression that enhances piano and electric piano sounds, while the coaxial two-way speaker features a powerful eight-inch speaker plus tweeter, ensuring a sense of volume and excellent positioning.

The amplifier's bass reflex structure is optimized for keyboard instruments, with every detail adjusted for the best response. The chassis uses ABS polymer for its lightweight, durability, and excellent acoustic properties, allowing for a 3D design that achieves the ideal cabinet resonance.

The VX50KB amplifier also features a three-band master EQ with BASS, MIDDLE, and TREBLE controls, providing flexible sound control. Its three-channel design meets the needs of any scene, whether you're using three keyboards, two keyboards and a mic, or a stereo keyboard output plus a mic.

In conclusion, the VX50KB 50W Compact Keyboard Amplifier with Nutube is a versatile, powerful, and innovative solution for musicians seeking high-quality sound and easy transportability.
