Behringer ULTRA-DI DI100 Professional Battery/Phantom Powered DI-Box

I recently purchased the Behringer DI400P Ultra-DI Passive DI Box, and I must say, I'm thoroughly impressed. From the moment I started using it, I've had nothing but positive experiences. Firstly, I haven't encountered any issues whatsoever. The DI box operates flawlessly, delivering clean and clear signals without any noise interference. This level of performance has greatly enhanced my audio setup, allowing for professional-quality sound reproduction.Moreover, the DI400P is incredibly comfortable to use. Its compact and lightweight design makes it easy to transport and integrate into my setup without taking up too much space. Whether I'm using it in the studio or on stage, it's always a reliable companion.Overall, I couldn't be happier with my purchase. The Behringer DI400P Ultra-DI Passive DI Box has exceeded my expectations in terms of performance, reliability, and comfort. It's definitely a must-have for any audio enthusiast or professional musician.

I’m a gigging keyboard player and have this in my rig after my keyboard sub mixer, so I can just output a stereo XLR pair to the stage box / main mixer inputs. Power is via a standard mains kettle lead (supplied with it) which is always better than a wall wart PSU.This is a 4 channel unit but I’m only using 2 as a stereo pair. It offers the usual DI features you would expect to find, including jack and XLR inputs, and individual channel switches for ground lift, 20db boost, phase reverse, and an 8kHz cut in case you need it. Inputs are on the rear of the rack, output is on the front of the rack via balanced XLR so no need to dig around the back of the rack in the dark on stage! Perhaps most importantly for a DI box, the sound output is clean and quiet. 🤫I prefer this to the external foot pedal sized DI box type as this stays fully wired in my rack, meaning a little less set up time and reduced cable trailing on the stage - all I need to do is to plug the main mixer input XLR cables into the XLR outputs on the front of the unit. 👍

A great unit for musicians, BUT why on earth are the jack sockets at the back!!! AND, the main XLR outputs at the front!! What on earth were the Behringer design team thinking off. Don't they realise that as musicians you want to jack into a front socket, link to your amp, again from a front socket, AND crucially be able to adjust the attenuation, at the FRONT? The only thing at the back should be the XLR's - everything else should be at the front.Rant over - it's still a great unit. If you can get your head around the peculiar layout, it does it's job very well. I've added an extra jack sockets panel just below the unit(with 8 x jack sockets), to enable musicians to jack into the 'front' of the rack unit that I've put together to avoid having to scrabble around the back.

Does Behringer make the best quality audio products around? No. But are they inexpensive and reliable? Yes.I keep this one in my keyboard case, along with a couple of jack leads, so I can always plug into a sound system if I arrive at a new venue that doesn't have enough of its own kit.I've also used the link function to send an output to the sound desk for FOH while also feeding a small powered foldback speaker for myself.You'll notice that all the connections are on the top, rather than front and back of the unit as with most other DI boxes. I quite like this - because it makes it easy to plug everything in on a crowded stage - but you might not.

Classic compact DI box. Does exactly what it’s supposed to. Great little item for the money.Happy with it.

DI boxes (I think it stands for Direct Inject, but I've also heard them called Direct Input) allow an unbalanced signal or any impedence that may be coming from an instrument, a microphone or another audio source, to be converted to a balanced microphone-level signal suitable for your mixing desk. This Behringer DI Box is fairly large (perhaps 6 inches square and three inches deep) in a rugged steelcase with outsized rubber bumpers. Its design gives you confidence that it will just work, and indeed it does, taking its power from the mixing desk (you can add a PP9 9 Volt battery if you wish, but it shouldn't be needed).The inputs are quarter inch jack or XLR (note that these are unbalanced, so only one signal pin is connected - if you have a balanced audio source, like most microphones, you don't need a DI Box). There's a pass through quarter inch jack, so you can also plug into a monitor amp or something similar. There are also two attenuator buttons, that drop the signal level by -20 dB or -40dB. On the back there's the balanced XLR output and a "ground lift" button, which can eliminate buzz and hum if you have two grounding points in circuit. There's also the door to the battery compartment, a red LED to show you the device is receiving phantom power from the mixing desk, and another unlabelled button that the instruction leaflet claims to be a speaker cabinet simulator. It is nothing of the sort - the leaflet is wrong. It's the on-off power button for the internal battery. I haven't tried using that one. If you want cabinet effects, try the Behringer Ultra-G instead.The idea is that you have the DI Box (or boxes - I use two) on stage or in the performance area, and the balanced XLR cable back to the mixing desk can be as long as you like, within reason, as having a positive and negative signal means that any induced interference cancels out, giving a nice clean signal at the desk. The boxes stack nicely - they don't clip together, but they rest on top of each other quite comfortably.The Behringer DI Boxes (this one and the Ultra-G) are way more stylish than most of the alternatives. Behringer also does a 2-channel stereo box, the DI20, but I like the look and feel of this one so much more, and I want the flexibility to place them separately, so I prefer to have two DI 100s.I'd hesitate to use this DI Bix if you don't have phantom power - what if the battery runs out mid-performance? Other than that, they're a great choice.
