  • Converts any unbalanced line-level signal to balanced mic-level output
  • Provides impedance and signal matching for the direct connection of instruments to amplifiers and mixers
  • Allows the use of long cables without losing high frequencies
  • Thru/Out jack lets you send the unbalanced signal to an onstage amplifier while the balanced signal is routed to the mixer

Behringer ULTRA-DI DI400P Passive Direct Box


from Missouri

Comments about Behringer ULTRA-DI DI400P Passive Direct Box:

Decided to try a Low-Z connection with XLR connectors from my effects pedals to the mixer to see if it be better than using the High-Z TRS connectors. The Behringer ULTRA-DI DI400P Passive Direct Box was the least expensive product offered. But it is metal and seems well constructed and it works fine. The first noticable advantage is that with the longer low-z cable I can easily run the cable off to the sides of stage set-ups. Getting the cable off to the side means less duct taping when the cables are stretched out. I haven't noticed much difference in the sound quality but low-z is typically a better signal.
