The Warm Audio WA-DI-A is an active direct box built around a custom-wound CineMag USA transformer and 100% Class-A discrete analog circuitry. It converts high-impedance instrument signals from guitars, basses, and keyboards into balanced, low-impedance mic-level output without degrading the source tone. The unit operates in active mode via 48V phantom power or dual 9V batteries (1,600+ hours of battery life), and can also be switched to passive mode for added versatility.
