The one-piece ABS chassis ensures high durability and great sound quality while keeping the weight light.The warm vacuum tube sound of NutubeBy 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 rangeThe 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 reproductionA 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.Three-band master EQ allows flexible sound controlThe 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.Three-channel design meets the demands of any scene.A rich array of input/output jacksThis 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.
