An Active DI Box That’s Anything but Ordinary Whether you play guitars or basses with passive pickups, you’ll need a direct box that won’t diminish your instrument’s tone when recording or plugging into the board. Using premium components like a Cinemag transformer and leveraging elite build quality, the Warm Audio WA-DI-A Active Direct Box is more than just a basic DI. There is no specific rule on when to use active vs. passive DIs, but a good guide is to use active direct boxes with passive sources like guitars and basses with passive pickups. If you’re looking for a professional, durable DI, the Active Direct Box from Warm Audio delivers premium features that help solve many audio issues live and in the studio. Active direct box with Cinemag transformer Converts a high-impedance, unbalanced signal to a low-impedance, balanced signal Leaves your instrument’s tone and clarity intact Variable pad from -3dB to -30dB lets you set an optimal input level to prevent distortion Ground lift switch helps eliminate buzz and hum caused by ground loops Route your amp signal to a live mixer or recording interface Intuitive front- and rear-panel layout Sturdy all-metal chassis can withstand the most rigorous use 1,600 operational hours on a set of fresh, high-quality 9-volt batteries Intuitive, full-featured inputs and controls Plug in your guitar, bass, keyboard, or other high-impedance instruments on the unit’s front panel. The Thru jack sits beside it, for easy access to run a line out to your amp, and the converted signal exits the unit via a sturdy XLR jack on the rear panel. The front-panel switches include Phase, Ground Lift, and Amp Out. On the back panel, you can select passive or active operation, and choose to engage the variable pad. Runs on 48-volt phantom power or dual 9-volts The Warm Audio Active Direct Box is powered by 48-volt phantom power or by two 9-volts, with an operational life of over 1,600 hours on a fresh set of batteries. The unit auto-senses 48-volt phantom power — switching the unit automatically into active mode — and includes a 48-volt indicator light. When operating on batteries, manually select active or passive mode via the back-panel toggle switch. The batteries are easy to remove and replace when the faraway day comes for a new set!
