DIB-100
DI box. The unit is excellently crafted, does not colour the sound and works with a very generous input attenuation of -40 dB if required. (delamar.de)
DI boxes – small boxes for big impact(s)
There are only 2 letters that will extremely enhance your music space. You may have seen them yourself, heard about them, or use them regularly. It's hard to imagine a musician's everyday life without DI boxes because they are such handy tools. DI stands for Direct Input/Injection. You have your instrument here, your mixer or audio interface over there, and maybe one more PA system. Then you just connect everything up using the DI boxes easily. Why so? Now, before we dive into impedance, balancing and galvanic isolation (say whaaaat?!) … in a nutshell: It's all about level adjustment, a linear frequency response, clean signals for mixing and avoiding background noise in the rehearsal room, when recording and on stage. Yes, all of this. Sounds good? Especially this: Our DI boxes are actually affordable. We pay attention to quality and inexpensive products that fit into your everyday life and your budget. You want to learn more? Let's go. Come on!
DIB-102
"The IMG Stage Line DIB-102 convinces on the one hand with its low purchase price and on the other hand with its very stable housing. The frequency curve is exemplary." (tools4music 02/2010)
LTR-102
"Inexpensive line transformer. The workmanship and measured values of the LTR-102 are very decent." (Produktion Partner 03/2013)

DI boxes: your handy pocket-sized helpers
Whether in the rehearsal room, during home recording or on stage: Cumbersome devices that are look nice but don't perform or only confuse are not our thing. We want something very practical and robust equipment that's intuitive to use. And perfect signal transmission, of course. Like this:
The DIB-100 – our classic passive 1-channel DI box
Stereo jack for bass, guitar, keyboard, but also smartphone and laptop
Stereo jack for your amp
XLR connector for mixer or audio interface
Ground lift switch to reduce or eliminate ground loops
Attenuation/booster switch that attenuates or boosts the signal
Handy and extremely robust – perfect for tough everyday on-tour performance!

Too much talk isn't your thing? Here are the raw numbers:
Ground lift and attenuation switches are particularly useful and valuable on DI boxes and an additional connection for your amp offers more flexibility.
Intuitive plug and play: This allows you to connect DI boxes (with and without amp)
Connecting a DI box is quite easy: The jack cable from bass, guitar, keyboard, but also smartphone or laptop goes into the input of the DI box. Then you connect it using an XLR cable to your mixer or audio interface. And then you can even add an amplifier via the preamp out (also called through or line out). This allows you to send the unprocessed signal to an amplifier on stage as well as to your PA via the balanced XLR output. This is useful for bass players who only use their amp for on-stage monitoring – which drastically reduces stage volume. Bypasses can be buffered completely passively to allow for longer cable runs or effects pedals.
Not just a black box: How a DI box works
Dirty signals reduce the quality of your recording. That's not good because once a dirty signal gets in the mix, you can't really get rid of it anymore. Even if there are various ways to edit an audio track nowadays, a clean recording is always best.
And you probably want to ensure the best sound experience live, too. Without distortions and buzzing sounds on stage. And certainly not if the background noise is amplified via the amps or PA system and thus clearly audible to the audience.
The solution: a DI box. It will take care of all of that for you if you just connect it in between. And even more. What does it do exactly?
What do you need a DI box for?
Equipment with a jack connection such as bass, guitar, keyboard, but also smartphones and laptops have a higher level and not the microphone signal level. Mixers and audio interfaces. To align both sides, the DI box lowers the output level of the bass, guitar and keyboard to the much lower input level of mixers and audio interfaces.
Impedance matching lowers the output impedance of the bass, guitar and keyboard to the much lower input impedance of the mixer or audio interface. Without sound losses. Your sound stays clear, your transients (short impulses of the instrument like vibrating a string, hitting your tom or snare, etc.) stay sharp.
It converts the unbalanced output signal from the bass, guitar and keyboard into a balanced one. This is particularly important when covering distances with long cables. Unbalanced signals are susceptible to interference. To make it short: Here, the signal is mirrored and rotated by 180° – AKA phase reversal. It's then turned back at the input of the mixer or audio interface. The two in-phase signals are superimposed and amplified while anti-phase background noise is cancelled out.
Thanks to the integrated ground lift switch, you ensure galvanic isolation and prevent ground loops. More precisely: With a switchable ground lift, you can disconnect pin 1 on the XLR jack of the DI box. This prevents current from flowing between the DI and the mic preamp along the shielding. In turn, this interrupts the ground loop and eliminates that noise.

Not a tough question: 1-channel vs. 2-channel box
Our classic, the DIB-100, has proven itself for over 30 years
“All in all, this is – without hesitation – a DI box that impresses with (…) great workmanship and fantastic signal attenuation. So, we can give it a 'Pass!' in the IMG STAGELINE DIB-100 test report – especially considering the low purchase price." - DELAMAR
You need more inputs, for example for your keyboard or your digital piano?
Then let us introduce you to our DIB-102: A passive 2-channel DI box
3-way attenuation switch (0/-20/-40 dB) per channel
1 ground lift switch per channel
1 instrument loop-through output per channel
Wideband balancing transformer
Stable metal housing – even survives the rougher on-stage performances!
Then let us introduce you to our DIB-102: A passive 2-channel DI box

You can also use the 2-channel box for only one channel. But you can also use two 1-channel boxes as a 2-channel box.
Not so passive: The benefits of passive DI boxes
The most common among the DI boxes are the passive ones for active instruments. A big plus here is that passive DI boxes don't need power. This means you don't have to supply them with energy in the tangle of sockets. And another benefit: The reliable galvanic isolation puts an end to ground loops.
Theory is all well and good, but what about in practice? Examples for using passive DI boxes
In this page, we will talk about the use of DI boxes for recording, in the rehearsal room or on stage. We are happy to show you application options for our DIB-100 or DIB-102:
“Hey, IMG STAGELINE, do you have more than DI boxes up your sleeve?” – “Glad that you asked!”
