RapcoHorizon DB-1 Reviews

Best bang for the buck

I assist with sound production at the church that I attend, and we use several different brands/models of DI box. The DB-1 has comparable reliability and sound quality than some units costing considerably more. We just bought 2 more of the DB-1 (we've had a couple for years) to replace a couple higher priced units that had failed.

Affordable, reliable, quite DI

No need for an expensive DI. This one does the trick. We always have a handful of these at the ready when we're on the road with various bands.
