Mackie MDB-USB 2-Channel USB Direct Box (DI) With 24-bit/96kHz USB Audio Input, Headphone Output and Ground Lift

The USB version is great. Solidly built, pleasing to use and crystal clear audio. Couldn't be happier.

Muy bueno

I needed a solid, affordable, balanced DAC to run from my pc, to LOXJIE P20 balanced tube amp, to Focal Elex headphones. The Mackie USB Signal Direct Box fit the bill. Mackie has a strong reputation in the music world, and this well-built little unit does just what it’s designed to do - provide a clean, high resolution signal.

ステージ上でPCやタブレットからPAにオケや動画の音声出しをすることが増えていますが、シンプルかつ安価にそれを実現するアイテムです。細いケーブルを引き回さずに済むのでノイズと無縁になりますし、GNDリフトスイッチがあるのでハムともさよならできます。不安定で事故の元でしかないミニプラグを使わずに済むのはありがたい。volノブが出っ張ってるのが残念なので星4つ。

I needed one of these for main PC audio to capture game audio and some OBS monitored stuff and another one to capture communications audio, so I could feed that to another channel with it's own mix that went back out to a BEHRINGER U-PHORIA UMC202HD, 2-Channel from that bus, so the people on coms wouldn't have to hear themselves come back at them. I also had another UMC202HD to capture the main mix from the mixer to throw into OBS. Both devices are plug and play and are completely clean without buzz/noise. I used to run everything through the 1/8 inch jacks on the PC because it was good enough, but then I picked up a ton of cable whine and ground buzz out of no where that I couldn't seem to eliminate even though everything was running through a power conditioner. These devices solved my problems and have been work horses in my studio ever since.

I wanted this to work, it just doesn't. Here's my setup. I use a Behringer U-Phoria UMC404HD for guitar tracks when I feel like recording upstairs, I bought the MackieMDB-USB to power my KRK 8" Gen 5's. I wanted to keep my I/O's separate. My KRK's are tuned to my needs, the EQ is setup perfectly for what I want. All this thing has to do is deliver audio. There is nothing clipping in my signal chain. If I use my U-Phoria for audio, I can dime everything and my house shakes but I have clarity. If I use the MackieMDB-USB, anything about 60-70% is distorting in any part of the chain. This is audio interface straight to powered studio monitors via XLR. Nothing inbetween. Frankly the volume level doesn't even come close to my original solution, even with everything clipping. I'm not going to go deep into how I performed my troubleshooting, but I tried different USB cables, ports, and chipset (ie: USB 2.0 vs 3.0). I changed outputs and audio resolutions. I even looked to see if maybe a different driver existed. At the end of the day this should be a device that's very simple. I plug it in and use it. I feel I gave it a fair shake with my troubleshooting. Seeing how my current product reacts and handles audio, and how this mackie fails right out of the box. I just don't have faith that this is a technical issue or defective product. In that aspect, this should be a very simple tool.
