Product details

The Manley VOXBOX is a high-end analogue channel strip designed primarily for professional vocal recording and detailed instrument processing. It combines Manley’s transformer-coupled tube microphone preamplifier with a Pultec-inspired three-band equaliser, an ELOP® optical compressor, and a dedicated de-esser/limiter. Its all-tube signal path, flexible routing, and comprehensive metering make it a versatile solution for tracking and processing vocals, bass, guitars, and other studio sources.
