Fantastic headphone amp that's super configurable


Great product, with loads of inputs and outputs. I love having so many input choices as well, and the ability to blend auxiliary and main inputs, along with basic equalization controls gives everybody an opportunity to get their own mix. Surprisingly heavy, which I consider a good thing. The knobs are very close together, making it difficult to get access with cables, but Iit's not a big deal, and I'd rather have more controls stuffed into a single rack space than too few. Great price point as well. I'm very impressed with how clean the signal is from such a budget minded piece of equipment. Excellent product. Mackie does it again.
