Product Description


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.

  • Four channel active direct box
  • Switchable input attenuation allows input levels of up to +40 dB
  • Low pass filter available on every channel
  • Ground lift switch eliminates typical ground loop problems
