Rapco Passive Direct Box DB-1

The Rapco DB-1's simple design offers reliable input jacks as well as a loop-through 1/4 inch jack.

Plug any instrument level signal (and some line level) into the box, interface with a standard XLR mic cable into the Lo-Z output, and you're ready to plug the output "directly" into a mixing console. A ground lift switch is provided for buzz-free operation in almost any environment.
