The DB-1 is a simple passive direct box that offers clean and 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 DB-1 preserves the "punch" and clarity of a sound that is often lost when placing a microphone in front of 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 sound of such current equipment as FM synthesizers and digital drum machines.

The DB-1 may be inserted into the signal path at virtually any stage. For instance, a bass guitar signal can be "taken direct" for a clean, natural tone, from a preamplifier or line output for a punchier or "equalized" sound, or from the speaker output of the amplifier if a dirtier "edge" is desired.

Built for the road, but equally at home in the recording studio, the DB-1 is housed in a rugged 16-gauge steel and aluminum "Uni-box" construction enclosure. The uniquely slotted side channels allow for stacking on top or strapping side-to-side of virtually any number of Pro Co Monoface devices using the Uni-box construction.

    DB-1 Direct Box is rated 4.5 out of 5 by 2.
    Rated 4 out of 5 by from Best No-Frills Direct Box I run our school's auditorium and video production department, so money is tight, but demands for quality continue to increase. Since I am also a bassist, I am quite familiar with the pros and cons of many direct boxes on the market. While this is a very basic, no-frills direct box, I find that it is one of the best in this price range. It delivers a clean, reasonably uncolored sound, and is durable. You can't go wrong with this DI.

    Rated 5 out of 5 by from Terrific so far!!! I've had the Pro-Co Sound DB-1 for only a couple of weeks, so I can't speak to its durability except to say that it's built quite sturdily. Time will tell. But so far it's doing exactly what I hoped it would do -- improve my sound dramatically. I play bass in my church. The sound booth and mixing board are a long way from the stage and the unbalanced signal from my instrument cable was degrading by the time it reached its destination. The DB-1 is a passive direct box that converts the unbalanced signal from my bass to a balanced one. The minute I plugged into it my sound became much punchier and crisper. The occasional pops and crackles that had plagued my sound before all but disappeared and were replaced with a much cleaner and more consistent tone. I'd never used a direct box before. Now I'm wondering what took me so long. The DB-1 was recommended to me over other brands by the sound techs from our local association. It is simple to use: Just connect the cables, flip a switch and play. I am currently plugging into the DB-1 and then directly into the house mix. But the DB-1 also includes a parallel signal output that will allow me to continue connecting to the main board via an XLR cable, while connecting a second TS cable to amplifier. I am considering going that route and connecting to a small amp for use as a monitor (I currently have a piano player located between me and the side-fill monitor I've been using). Again, I've only had this box for two weeks. But so far I'm thrilled with the results and can't imagine playing without one. No downside so far. Thanks Pro Co, and thumbs-up for a great product.
