Superb quality and peformance. My sub actually works now! Whereas before it would create a high pitched annoying rattle (using two old logitech cpu subs inline). This unit was perfect for my 12u media controller rig. The ROLLS logo is clean and classy, the materails are high quality on all ends, even the super comfy rubber nobs that I've found nowhere else but my sibling's high end guitar equipment. But like I said I'm not an audio guy, maybe all equipment these days comes with the special little rubber nobs, but to me it made a huge difference knowing they likely did that because they enjoyed using and developing the product, and they themselves couldn't stand the cheap hollow plastic nobs you find these days. But hey that's another $1 in profit margin I suppose ...I haven't tested the mic output, nor do I plan on using them much, but definitely nice to have. In comparison to another 1U unit I purchased, which was an equalizer https://www.amazon.com/dp/B013JLZMZE/ by Behringer, the ROLLS unit was a joy to handle and play with, and the behringer felt like a DVD player you'd find at a cheap motel that has nothing but a chip, an LED, and cheap housing.The high quality $2 primo nobs on the ROLLS really allow for sensitive tuning, seriously every nob should be this nice. You audio people have been holding out on us!! Maybe at least convince Behringer to step it up. The loose plastic and hollow nobs on the behr feel like they'll snap off any day now. Not sure how, in the event you did have a pro musical rig with extreme sound, one would secure the behringer's physical settings without them rattling out of place. But for the price I will say, Behringer nailed it.The RM69 (great model name) is a simple, high quality, classy component that I would recommend for any user looking to ehance their rack with a solid mixer and mic amp - capable of a number of uses, both in audio and pc media setups. I am definitely a ROLLS fan now and will be purchasing all of my audio components from them if possible.Rolls RM69 MixMate 3 Mic/Source Mixer
