Professional Passive Direct Box

The Pro Co Model DB1 is a simple passive direct box that offers clean, reliable performance. It can be used for nearly any instrument or signal source, from electric bass, keyboards and drum machines to sub-mixers and external speaker outputs*.


The DB1 preserves the “punch” and clarity of the sound that is often lost when mic’ ing a speaker, while eliminating the leakage, distortion and coloration. The signal delivered to the P.A. or studio mixer is crisp and clean - a vital element in retaining the full depth and brilliant sound of digital instruments such as synthesizers and digital drum machines.


The DB1 may be inserted into the signal path at virtually any stage required. For instance, a bass guitar signal can be “taken direct” from the instrument for a clean, natural tone, from a preamp or line output for a punchier or “equalized” sound, or from the speaker output of the amp if a dirtier “edge” is desired. For stereo or multi-channel applications such as Keyboards or digital drums we recomend the DB2 or DB4A. The four-channel, rack-mountable DB4A Quad Direct Box is highly recommended for multi-channel applications.


Built for the road, but equally at home in the recording studio, the DB1’s rugged 16-gauge steel and aluminum “Uni-box” enclosure is finished in a durable black texture powder coat finish with black anodized aluminum side channels. The uniquely slotted side channels allow for stacking on top or strapping side-to-side of virtually any number of Pro Co TradeTools devices using the Uni-box construction. Easy to read control graphics are incorporated into the Lexan® top panel overlay.
