Independent shopping perspective

The Korena take

Warm Audio’s Passive Direct Box converts an instrument-level signal to a balanced, mic-level output. It has a custom-wound CineMag USA transformer, 1 Mohm input impedance, and a variable pad covering -3 to -30 dB. The 600-ohm balanced output makes it a focused solution for routing instrument signals into a mic-level path, including longer cable runs. Its extruded aluminum enclosure, metal knob, and switches are part of a deliberately rugged design.
