This mixer has never left my house and is in 100% new condition. When not in use, it has always been covered to keep dust out of the faders etc. The MG16XU is a really well-thought out design and with its metal chassis, is suitable for both live and recording applications. It features 10 XLR/1/4" Mic w Phantom inputs, and/or up to 16 Line inputs (8 mono + 4 stereo), 4 Group Buses + 1 Stereo Bus (XLR or 1/4" balanced outputs) and 4 Aux Sends (including FX). Note that this model, the XU, also has 24-bit/192kHz 2 in/2out USB Audio Functions.
