A&H are the only ones who include the power supply in the mixers, however this one is not using a standard IEC inlet for some strange reason. I will use this for connecting condenser mics to a video camcorder, live for my in-ear monitoring, and occasionally as a submitter when my larger mixer runs out of inputs. I just wish there was a mono line-level input (the mono channels have hi-Z instrument inputs and the stereo channels won't blend to mono when only one jack is connected). It seems they could have made the left input mono if the right input wasn't used without adding much to the cost.. Anyway, give the price, the sound quality is top.
