This unit is in Mint condition 100% fully working order. If your looking for a digital unit that works exactly like a tape machine this is it. On board it has built in mixer, also has a aux in and out for outboard effects processing it even has a high quality preamp on board so that way you can use it for your microphones and has phantom power for condensers. I can not over emphasize how high quality the pres are think presonus or avalon. Also this unit can be used flawlessly with any outboard mixer since it has 8 additional outputs onboard. Also it accepts optional effects board and the hard drive is upgradeable to a larger capacity drive, it has digital I/O and it also has a full meter bridge not just dots that turn green to red. There is so much to say about this unit it is absolutely amazing and easy to use but I have decided to change the way I record so I am selling a lot of my used equipment to fund it. Check my other listings for other products I have for sale, I have many great deals on very good equipment. If interested email me at diolives777(at)gmail(dot)com or call
