The DB-1 is a professional quality passive direct box for connection of unbalanced musical instruments, line-level sources, and guitar amplifier outputs to low-Z balanced microphone input for PA or recording. 1/4" (6.35mm) input (with parallel 1/4" output). Switches for speaker/line-level attenuation, high-cut filter, and ground lift. Male XLR-type balanced mic-level output. Uses Pro Co DBT-1 transformer (20k/150 ohm).

Pro Co DB1 Features
  • Floating transformer-balanced XLR output for maximum isolation
  • SPKR mode handles amplifiers up to 600W RMS
  • HI CUT filter reduces distortion
  • GND/LIFT switch eliminates hum and buzz
  • Rugged "Uni-box" construction for super-strength and shielding
  • Recessed switches and connectors resist damage
  • Passive design requires no batteries or phantom power
