"Love the fact it's an interface & USB powered. Solidly built. Pots turn smoothly. My PC recognizes it in sound settings but can't hear any audio coming from the PC thru the headphone jack. Wish there was better direction & larger font on what's included. Online video was of no help."
"After my installation was completed (and it was a breeze), I’m well on my way with what I wanted this unit for!! It’s living up to my expectations; and it wasn’t HYPE that made me buy it!! It was the REPUTATION that this company is creating! Dependability, affordability, and ease of use!! Buy yours today!! See their full line!!"
"Wow, Bang for Buck ( $4. 50 / ch, 8 analog, 2 usb). This little 8 channel mixer is amazing. I have a little XLR interface with a few Mic Pre-Amps, it also has two additional line inputs. These are fixed level and I had not found much that I could use them for. Along comes the Amazing LINE8 USB. Now I can mix 4 inputs with gain control into each of my two spare inputs. I can also put a keyboard stereo output into my two outputs with level control. The maximum gain is somewhat limited on the input channels yet they are clean and noise free. (Probably not for SM7 type mics. ) Even with all channels at max gain the input noise is barely audible on the output. Wow, hats off to the engineering team. Given limited space and a very affordable price target they put together an impressive and versatile piece of gear. A great field or spare mixer as well. This is not "Top of the Line" studio gear. It does not try to be. It is well built, suitable for daily use and highly adaptable."
