dbxDI1 Active 1-Channel Direct Box

I am only using this piece of gear as a DI unbalanced to balanced converter. It works so well. Any one of my instruments (all of which have unbalanced outputs) can all be heard crystal clear and ready for recording. I purchased this used and in great condition and I won on this. Great value here. Now in the future, when I get a mixing board, I am still set with this. Thanks!

After chasing down some pervasive and annoying USB noise to a ground loop issue, this DI box did the trick in ridding my system of dreaded hum. I connect the unbalanced output of my audio interface to the balanced inputs on my JBL LSR system, hit the ground lift switch and the hum is instantly eliminated. I'm not entirely sure why these are so expensive, (I paid $50) but the build quality is very sturdy and after being driven mad by USB noise for the past months I'm just glad I was able to fix it. There is a bit of volume drop on the speakers, but this is easily overcome. Otherwise, the unit does everything I could ever dream of; clean quiet connections.

Priced properly, works properly! Attenuator is nice to have as well. Used to connect unbalanced outputs to balanced inputs.

I love this thing. Used it for drum machine 1/4" outs to XLR snake. No problems. Quiet as in NO noise. I didn't use the line mixer feature but as a direct box only. Has all the features of an active direct box with atteniuation, ground lift, etc. A no brainer at this price.

Amazing product for the price! I am so surprised that this piece of technology has not taken off in the market yet. Four high-quality active direct boxes for under $100? That's impressive. So grateful I found it and freed up four individual direct boxes!No noise. Individual signal control. Three pad settings. Built in mixer. Individual ground lift option.Heads up, this unit requires an external power unit (wart included). I do not believe it functions with phantom power.

Ideal for things like multi-keyboard to mixer interfacing. Not requiring phantom is one advantage, and the variable attenuation choices allows for 0dB interfacing, which is better for system S/N when it can be used, which is more often than not with mixers having line inputs or the like.Cons are mild and given the price should be considered reasonable compromises: 1. a. DI channels do not have parallel outputs for connecting both to local amp and to mixer b. DI channels do not appear isolate the returns for inputs from each other, so in some cases this can cause source-side ground loop issues. Use of common AC circuit and the like mitigates these concerns. 2. Mixer is useful to headphone out, but other output is on RCA phono jacks, which is a very odd choice in general for use on stages. If these were current-balanced TRS it'd be lots more useful, and add nearly zero cost. What were the designers thinking on that point?

Es un equipo imprescindible en tarima y que mejor utilizar 1 solo para 4 instrumentos.

The concept is good but the unit didn't operate as expected. Volume knobs didn't work and it was no different than plugging straight into my mackie mixer.

Great quality. Simple and easy to use.

La compre por su impedancia de salida a 600 ohmios, para equipos de radioaficionado es ideal para su adaptacion hifi ssb, tiene dos canales independientes, aunque si es verdad que atenua mucho su insercion aun asi es excelente la calidad que ofrece.

I bought this for one particular purpose.I need to split my guitar signal into two paths, one fed to an amplifier, the other into an audio interface for recording the direct guitar sound for 're-amping' using software plugins. Splitting the signal allows me to record the guitar amp (if needed) at the same time as recording the dry guitar signal for processing after the event (re-amping)Latency is a huge issue when recording, and this method eliminates the problem as you can hear the guitar amp with zero latency while playing along with the tracks already recorded.There are other practical applications of this DI box, but I needed it for this specific task and it works well.The ground-lift switch eliminates the (horrendous) hum I had from a ground loop.

fattura impeccabile, funzionamento tramite phantom ottima

I have a few of these DI boxes. They are sturdy, value for money and never need batteries. Their downside is that compared to active DIs, they do have a lower volume output due to their passive nature. But that is an issue for all passive DIs, not just this model. It's about using the right tool for the right job. These are great for any instrument with an active pickup. They also work very well in a pedal board setup where other units can adjust the volume. It has great sound quality and the ability to adjust signal output is useful. The dbx DJDI DI box is of excellent quality and I can recommend them.
