ProCo DB-1 Direct Box
OVERVIEW
No gimmicks or frills, just the right stuff.
The DB-1's simple design offers reliable input jacks as well as a loop-through 1/4 in. 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.
FEATURES
- Transforms Hi-Z 1/4 in. input to balanced Lo-Z XLR output
- Heavy duty steel box
- Superior quality connectors and transformer
- Recessed connectors and switches to prevent damage
- Ground lift switch to eliminate hum
- Paralleled 1/4 inch output for on-stage monitoring
- Individually tested for performance and quality
Order yours today for simplicity and reliability.
