Whirlwind IMP2 Passive Instrument Direct Box DI

The Whirlwind IMP2 is a single-channel passive direct box that converts unbalanced instrument-level or line-level signals to balanced, low-impedance mic-level signals for connection to a mixing console, audio interface, or snake. At its core is Whirlwind's proprietary TRHL transformer, which is riveted directly to the metal chassis for mechanical strength that glue-mounted alternatives cannot match. This construction detail matters on the road, where DI boxes endure repeated drops, vibrations, and the general abuse of live sound work.

The IMP2 features parallel-wired 1/4-inch input and output jacks, allowing you to pass the original signal through to a stage amplifier while simultaneously sending a balanced feed to front-of-house. A ground lift switch is included to isolate hum and buzz caused by ground loops, a common issue when connecting instruments to PA systems. With no batteries or phantom power needed, the IMP2 is always ready to go. Its compact footprint and rugged metal enclosure make it easy to fit on any pedalboard, in a rack drawer, or tossed into a gig bag. For musicians and engineers who need a straightforward, reliable DI at an accessible price, the IMP2 delivers exactly that.
