The direct road to your goal
Looking for a multi-channel direct injection box that offers reliable assistance in all your studio and stage activities? A box that allows you to connect several signals to your console without hum or other noises, even over long distances? Look no further, because here it is: BEHRINGER's ULTRA-DI PRO DI4000.
Hook up anything. And we mean anything.
Up to 40 dB of switchable input attenuation allows you not only to connect unbalanced line and instrument signals, but even a +50-dBu amplifier output. And for especially weak signals, a 20-dB preamp is included. Did we forget anything?
Excellent audio specifications guarantee pure sound
Our ULTRA-DI PRO gives you all the advantages of an active DI box. Varying input impedance has no effect on the rest of the signal processing chain – no matter what you hook up, thanks to the high-quality buffer amplifier. The DI4000 also features our proven OT-1 transformer, ensuring ultra-linear frequency response from 10 Hz to 50 kHz. A switchable 6 dB/octave low-pass filter allows problem-free direct connection of guitar and bass amps. The DI4000 sets new standards with its excellent S/N ratio of -95 dB and THD value of <0.005%. No matter how you look at it, the ULTRA-DI PRO is worth every penny. Let your ears be the judge.
Your universal tool in the studio and on stage
The DI4000 gives you two balanced inputs (XLR and 1/4" TRS), a balanced output (XLR) and a practical link output (1/4" phone) per channel. An internal power supply with a shielded toroidal transformer gets it humming. Hum-free. Illuminated buttons and super-precise 8-segment LED displays keep you in the picture at all times. So much power in only one rack space. No rack should be without it. Can you afford not to have one in yours?
