## Description

PylePro Model : PDC22 1/4'' XLR Direct Box Dual 1/4'' Instrument To Balanced & Unbalanced (1/4'' XLR) Direct Box Construction: All Steel Chassis Ground Lift: Switch-Able Ground Lift Balanced Output: 600 Balanced XLR Jack Instrument Input: 50K Unbalanced TS Jack Parallel (Link) Out: 50K Unbalanced TS Jack Input Attenuation: Switch-Able (0db,-20db,-40db) Two High-Quality Direct Boxes In One Convenient Enclosure Dimension: 5.5'' x 4.72 x 1.57 '' Pyle PDC22 is a necessity if you are looking for the higest quality of sound, with low distortion, noise, and eliminate ground loops. A DI unit, DI box, Direct Box, Direct Input, Direct Injection or simply DI is an electronic device that connects a high impedance, line level, unbalanced output signal to a low impedance mic level balanced input, usually via XLR connector. DIs are frequently used to connect an electric guitar or electric bass to a mixing console's microphone input. The DI performs level matching, balancing, and either active buffering or passive impedance bridging to minimise noise, distortion, and ground loops. DIs do not perform impedance matching. Pyle has been in business for over 35 years, and their manufacturing experience and expertise is easy to see - and hear.

Review: Great economical choice! - I've been very happy with these. They are quite economical, and work well. They sound is clean. I'm regularly using with both a guitar, and with a Hi-Z drum module output. I have occasionally used to hooking up a regular computer sound output to the mixer. It worked well for this too.
Review: Flawless in 2 years' use - I have experienced only good things with this box over the 2 years I have gigged with it! Even the owner/sound-man of the local pub wants to get some for his stage after seeing mine! So far (knock on wood), flawless! And the sound quality seems just fine...

## Questions & Answers

**Q: What output cables does this require?**
A: The signal can go either direction, so output is relative.  The XLR side is male, so the cable would need a female connector, and the 1/4" / TRS / TS / Phone side is female, so you would need a cable with a male plug for this side.  There's also a pass-through 1/4" jack wired in parallel with the adjacent 1/4" jack, as can be seen in the pictures.I'd buy this if... electrical noise was not an issue.  The unit I got allows excessive electrical noise in anytime it's placed near other equipment, so it has to sit a foot or two away in an open space.  I'm not very happy with the design of the unit in that respect, but other than that it's working well for me and is inexpensive.

**Q: What's the frequency respond range? is it comparable to prodi and jdi?**
A: Yes full Hz response from 20 to 20,000 hz

**Q: How much does it weight?**
A: Not more than a pound or two, but really... save yourself the headache and go with 2 LiveWires. I've had my two for almost a year with about 75% beach gigs and they still work like new. The Pyle had problems out of the box.

**Q: Any suggestions on how to get rid of the loud signal noise? Had clean guitar and bass going in, out via xlr to interface, sound unusable.**
A: I have the one with the xlr in/out as well. It is noisy.. suspect the TRS inputs I'm using in my Stereo Out Processor is a different wiring. 
My Guy is adding a ground. I need the vertical outputs this box has, all bundled in a aluminum travel  case.  Plug and play. E

### ⭐⭐⭐⭐ Great PASSIVE Direct Box - Know what that means before you get it.
*by R***R on May 17, 2018*

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!
