Hey guys im selling my Alesis Multimix 8 USB mixer. Its in great working condition as i look after my equipment to a high standard, i just want rid of it tho as i have upgraded mixers. It is compatible with both P.C and MAC, however a buzzing sound was heard on recording with the OSX models. I looked into this and it turns out it is a manufacturing fault with just osx models its not the mixer, Like i said already it works fine and its super easy to use just plug-in and play, original box and manual and instalation disk. First offer above 50 can have it thanks. Cant take a photo as i have no camera, but here is a link to the same model http://www.gigasonic.com/images/multimix8usb.jpg Louis - 07516891399
