Review: Good rack mounted DI box - 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. 👍
Review: A rugged solution to connecting almost anything to your mixing desk - 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.

## Questions & Answers

**Q: Does this work for connecting the sound output from a PC or MP3 player into a PA system using a Stereo 1/8" TRS to Mono 1/4" TS cable?**
A: Yes that should be fine! :) You would also need an XLR to connect the DI Box to the PA.

**Q: I want to record digital piano and play live at church. Should I get Pyle-Pro PDC21 for $8 or is this significantly better?**
A: A normal DI box is $50 so I wouldn't go too much lower than this. These seem to work well. I've only had one go bad in the past year or so and I purchased like 8 for my church.

**Q: Can this reduce a speaker level signal to a line level signal? E.g. if I wanted to take a speaker level and connect it to a mixer.**
A: YES.  The other answers are not accurate.  This device as well as many other DI Boxes can make a Line Level 'copy' of the high power signal going to a speaker.  This is a common use however this yes comes with a major caveat.  The source (1/4 " INPUT) can be a highly amplified signal, such as the speaker output of a 100W guitar amplifier.  The output signal (XLR OUTPUT) will be what the mixer wants (Line Level).  CAVEAT: There must be a load connected to the THRU (Parallel OUT on this device).  This load can be a speaker or speaker load simulator, basically what you would normally connect to the amp.  Without a load connected, no signal flows and nothing will be output.  Worse yet, without a load connected, many amps will fry.  Amp to DI box to Speaker(1/4" OUT) and Mixer (XLR OUTPUT) is commonly used by guitarists.  This allows the PA Mixer or Recording Audio Interface to get all the good sound that the guitar signal chain has built, only missing coloring from the speaker cabinet.  If needing your speakers to be silent while still getting a good output on the XLR, adding a decent amp Attenuator or Load Simulator after the DI Box can reduce the power reaching the speaker to or near zero.  Note: Many higher end Attenuators and Load Simulators have a built in DI Box.

**Q: can i use this to hook up my 6505+ to my m-box?**
A: If you have the combo version, it has an XLR out already, so no DI required.  The head version doesn't seem to have this option, so you could use the preamp out, but I'm not sure if you could hear a difference between using a DI or running the 1/4" into the line level input of the M-Box.  You'll lose the tone you get from the power amp tubes either way.  The main point of a DI is to convert a 1/4" instrument signal to a balanced XLR signal if you're going into a stage snake.  Effectively running a 50' or 100' 1/4" cable will generally introduce noise and reduce signal quality, so the DI is a great option.  I've used this passive DI box in live situations for the past year, and it's worked like a champ.  I run my tracks (from an iPod) through it.

### ⭐⭐⭐⭐ Excellent value
*by P***. on 23 January 2024*

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.
