No! While its name suggests correctly that it was designed with vocal recording and processing in mind, the VOXBOX is a versatile workhorse that excels on a wide range of sources. If it's good enough for the "money channel" it's good enough for your guitars and drums! The all-tube signal path, musical EQ, and flexible dynamics sections make it an incredible tool for tracking bass, acoustic guitars, drums, and other instruments. Many professional engineers consider the VOXBOX their secret weapon for adding a high-end, analog polish to any track, not just voice. Try tracking DI rock guitars through this tube-box, straight into your DAW, you will FEEL the difference!

The VOXBOX is unique in that it's a "total package" vocal processor, combining a full suite of Manley’s most revered circuit designs—the Mono Mic Preamp, a reimagined ELOP® compressor, an extended Pultec-style EQ, and a dedicated de-esser/limiter—into one meticulously crafted unit. Unlike most channel strips, the VOXBOX is an all-tube, Class A signal path from start to finish, built with an innovative design that places the compressor before the preamplifier to prevent clipping and ensure pristine sound.

The VOXBOX compressor is based on a passive optical circuit with minimal components, a design that adds no measurable distortion or noise. Its unique topology places the compression before the mic preamplifier, which helps to prevent the preamp from clipping and allows for transparent gain reduction. The compression ratio is generally a smooth 3:1, but the versatile attack and release controls provide a wide range of characteristics, from subtle and transparent to more aggressive, while always remaining musical.

Manley Power® is a proprietary, high-voltage switch-mode power supply designed specifically for our tube audio equipment. It provides a rock-solid, regulated 300-volt DC rail for the vacuum tubes, ensuring huge headroom and consistent performance worldwide. This modern power supply is empirically quieter than traditional designs, resulting in a lower noise floor and a sonic benefit of "blacker blacks" in the silence, along with a perceived increase in high-frequency clarity. It also accepts any voltage from 90V to 254V, making it universal for global use.

Yes, the VOXBOX is designed with flexible I/O to allow its sections to be used separately. The unit has both a “Preamp Out” and an “EQ Out,” allowing you to access the signal after the preamplifier/compressor stage or after the full channel strip. Additionally, an audio insert point allows external processors to be patched in between the two main sections, providing an even greater degree of creative control and routing flexibility.

The VOXBOX is an all-tube, Class A unit that features a carefully selected complement of vacuum tubes to achieve its signature sound. These include a 12AX7, a 12BH7, and a 6414/5965. Each tube is hand-tested and meticulously paired during the manufacturing process to ensure the highest performance, stability, and sonic integrity that Manley is known for.
