The DI-1000 is a high quality direct box with applications both in the recording studio and on the road, designed to withstand the most demanding situations. It can operate as either a passive impedance matching device via its built-in Jensen JT-DB-EP transformer, or as an active DI where the Sonic Maximizer circuit can be engaged with the signal still balanced at its output by the Jensen transformer. The DI-1000 is perfect for touring sound applications and recording studios, yielding excellent results with active or passive bass guitars, keyboards, and both acoustic and electric guitars, and delivering clear, pure and natural sound. Features: full-function BBE Sonic Maximizer for crystalline clarity and definition; Jensen JT-DB-EPC transformer for warmth and presence; purely passive or completely active operation; switchable 0/15dB/30dB pad switch; ground lift switch; balanced XLR output; 1/4" input and thru-put; military-spec circuit boards; extra-thick, extra-wide circuit board traces for unequaled electron flow; 1% metal film resistors throughout; solid 1/8" thick aluminum extrusion housing for light weight and superb strength; 5 year manufacturer warranty.
