Know before you buy
While it is optimized for vocals, the Voxbox is excellent for any source that benefits from tube warmth, including bass, acoustic guitars, and synths. Its versatile EQ and compression sections make it a powerful tool for shaping almost any instrument in your mix.
Yes, the compressor and de-esser sections are stereo-linkable. This makes it a viable option for stereo bus processing or tracking stereo sources like synths or drum overheads if you have a pair.
Like any high-end tube gear, you will eventually need to replace the vacuum tubes as they age, which is a standard part of owning professional analog equipment. The Voxbox is built to be robust, but keeping it in a well-ventilated rack space will help extend the life of the internal components.
The Voxbox uses an optical compressor design, which is known for its smooth, musical response. The 'Parametric' aspect refers to the specific way you can dial in the compression characteristics, offering a more nuanced, transparent control over dynamics compared to typical VCA-style compressors.
Yes, it includes insert points, which gives you the flexibility to patch in external gear between the preamp and the EQ or compression stages. This is particularly useful if you want to integrate a specific outboard reverb or a different style of EQ into your signal chain.
The Voxbox features a universal power supply that automatically handles mains voltages between 90 and 254 VAC. You can use it anywhere in the world without needing to worry about voltage switches or external transformers.
