The ULTRA DI DI4000 provides four active direct box channels in a single rack space enclosure. Unlike a passive DI where the frequency response of the signal can be altered depending on the connected impedance, an active DI buffers the input signal with an amplifier. This assures that the sound source will reach the mixer balanced and noise-free.
The input-buffering amplifier also ensures clean, pure and powerful sound when using extremely long cables. The ULTRA DI DI4000 features Behringer's OT-1 output transformer and the unit features a low pass filter and phase reverse and ground lift switches on every channel.

Comments about Behringer ULTRA-DI DI4000 Rackmount Direct Box:
We use this to run laptop audio into a board for PA at large and small meetings. So far it's worked every time and doesn't add distortion or very much noise. So this is actually our second one.

Comments about Behringer ULTRA-DI DI4000 Rackmount Direct Box:
This is great, as it can take inputs from the guitars, amps and keyboards. Replaces 4 DI boxes. ALL at a very affordable price.
