The IMP 2 converts a line or instrument level unbalanced signal to a low impedance mic level balanced signal. It's the ideal direct box for anyone requiring professional quality and durability in an economical package.
Features include:
1/4" parallel wired in/out jacks
Ground Lift switch to help isolate hum and buzz
Uses Whirlwind's TRHL transformer that's riveted, not glued, to the chassis
Built rugged on the inside and outside, this is the world famous DI found in pro systems everywhere.
Aesthetics
The IMP2 isn’t much to look at, but it doesn’t need to be. It’s available in basic black, if you want a different color you can spray paint it. Whirlwind claims that their salespeople have been known to take an IMP2 and drive over it with their car to prove its durability. However, if you spray paint or drive over your IMP2 it will probably void the warranty.

Direct boxes are often referred to as “DI” boxes. This stands for “Direct Injection” as their main purpose is to convert instrument signals into a format suitable for direct connection to a mixing console - without the use of a microphone.
A DI serves several basic functions
1. It converts a high impedance signal to a low impedance signal (although it will also accept a low impedance signal from a preamp, keyboard, active pickup or other electronic device).
2. It converts an unbalanced signal to balanced.
3. It reduces a strong instrument or line level signal (and sometimes even speaker level signal) to a mic level signal suitable for connection to the mic input of a mixing console.
4. It isolates electronic equipment on stage from the mixing console, which can help eliminate interference and noise caused by DC interaction or ground loops.
The IMP2 is a basic, yet rugged and high performance DI. It contains a high quality transformer (Whirlwind’s TRHL) for transparent response, parallel input and through jacks and a ground lift switch.
