PylePRO Premium Direct Injection Audio Box - Passive DI Unit Hum Eliminator w/ Input Attenuator to Connect Guitar & Bass - 1/4 Inch Impedance Transformer Connector to Balanced & Unbalanced XLR-PDC22 , Black

I bought two of these because they were inexpensive and worth a try. They have proven to be useful for a number of applications. Over the summer I used one between my portable PA and a couple of rechargable powered monitors. The attenuation feature came in handy as one of the monitors has a very hot input, so padding it down gave me more control over the volume. At church I've used them to run a stereo keyboard mix to the main PA so the dual channels is nice. I have been satisfied with the sound quality, but I haven't done any head-to-head comparisons with other units. I use mostly for my keyboards that are putting out a line level signal and where I have a lot of tone control available so I can't comment on how the DI might color the sound of a direct guitar, bass or similar instrument. Considering that a top rated professional DI costs 5 times more, these are a great value for the part time musician.

The only downside? The metal (but NOT plastic!) enclosure is a bit flimsy. It hit cement one day and got a little ding. Bummer. Plastic might have cracked. I got a dinged corner.But other than that? Flawless. Good sound, plenty of bells and whistles, and most importantly for a gigging keyboardist: STEREO! For the money, it's astoundingly good. And that metal enclosure? I wouldn't take it on a world tour, but it's perfect for the gigging weekend warrior like me. Highly recommended.

Very clean signal through this, sounds good. Only tested it briefly so far. Wanted to note here that I tried this and the "mini" one (PHE400) and in like 30 seconds of testing, this one seems to sound better.

So this is a good product for a decent price if you know what it is you're getting. What this is, is a passive direct box with nothing but a transformer to match impiedance between XLR balanced and 1/4" unbalanced. As such a few things to keep in mind are that this is not an amplifier, it has no active powered electronics inside. Also there is some inherent loss in any transformer, so the signal coming out may not be quite as strong as the signal going in. If you're looking for a lossless direct box with low impiedance, then you will want an active direct box with operational amplifiers and powered circuits. This is not on of those. But having said that, it does a fairly good job and is built like a brick ####-house. It has some serious weight to it, and if it fails as a proper direct box for you it can certainly be used as a theft deterrent device. Seriously though, good little unit. Since there is no active electronics there is little to no chance of inducing extra noise or hum. It does have some attenuation resistors (meaning it can make loud things quieter) for if you are feeding something with higher volume like a speaker output into something that's expecting lower volume like a microphone input. It also has the ability to do ground lift, if you're getting ground loop hum. (And if you don't know what that is, simply nod and act impressed.)All in all I rated it with 4 stars because as long as you know what you're getting, its a great little unit. But just be sure you do some reading on the differences between active and passive direct boxes. Happy Hunting!

This is an effective DI that just works without any fuss. I run a drum machine and my bass guitar through it and have no issues at all. I trust Pyle audio products, and this one doesn't disappoint.

Okay man what happend was like all my guitar amps with my death metal distortion settings when hooked together with all the pedals and cords to any of my guitars(sounds fine) but i have the static in the background when not playing and it’s so loud sometimes, it becomes frustrating or i get a headache but i know there are static and grain sound silencers or dampeners or whatever so i got on AMAZON 🤘😈 to look for it to play my death metal from my soul bro. So i find this thing one here the inject box or whatever and i could have sworn that i saw it cancels out static and plus i can hook up more of my instruments to it like i could plug in like 3 guitars and a bass and a electronic drumset and a keyboard at once or something wild of the sort. But i gotta have some giant robot thing called a PA system for it to work cause directions for guitar were all like “oh blah blah gotta connect it to PA SYSTEM to the amplifier then the guitar to the amp sound system or something stupid like ugh now i have to get more cords everywhere like usual i feel like a lost Vietnam veteran in the jungle stuck in vines. So many vines. Anyway from the physically held point of view and overall appearance it looks like it can do what it says and it has a lot of directions so if i think I understand it then everyone can understand it. Satisfying weight to it, not too light which is good cause light typically feels weaker. Not too heavy cause thank god lol. Two different panels in one small portable system at avery good deal. Keeping it even though itll be couple years til i get the pa system crap. That is what happened. I wanted no static on my guitars. (Sad hold F to pay respect rip george bush did titanic)

had noise proplem from my old lexicon fx unit for years when connected to my interface. with this solution had fixed the problem im very happy thanks!

As with so many other reviews, one of the switches was bad. It only took me about half an hour to open the box, repair the switch, and put it back together again. One of the screws holding the box together was stripped badly, so I had to replace it. The construction of the box itself is rugged and sturdy, but the stripped screw and bad switch mean poor quality. I don't know if anybody else has this problem, but this thing adds hum and reduces bass at the -20db setting, but sounds good in the other settings. I can't help thinking their choice of resistor values in the attenuation section was poor, but I'm not sure. For the price, though, you can't beat it! Despite the problems, I'm glad I bought it, and I will get a lot of good use out of it.
