You're serious about getting rid of all that excess noise on stage, but you've got so many line instruments you don't know where to start. The ADB-4 from Stewart can take care of all your high impedance problems. The ADB-4 is 4 active direct boxes, all in a module that only takes up half a space on your keyboard rack. It's a rugged, durable piece of equipment that packs a lot of DI power.

The Stewart ADB-1 is a single channel active direct box that allows an unbalanced source to directly feed a balanced input. Musical instruments, tape recorders, VCRs and sound projectors can be run "direct" to the mixing console, avoiding unnecessary degradation of sound quality. The ADB-1 operates on either phantom power or a 9-volt battery.
FEATURES: Flat response Low distortion Low noise Wide dynamic range No transformer RF protection on input and output Switchable ground isolation Flush mounted slide switches
