I am selling a unit that has been carefully used by a single owner. The front panel shows no signs of deterioration. This is an all-in-one, versatile audio interface that supports line input, Inst input, and microphone input. It can handle multiple channels of both analog (including Hi-Z) and digital, providing sufficient quality with just this one unit. High-speed Thunderbolt communication enables simultaneous 8-channel recording. The built-in clock boasts the high precision that is characteristic of Apogee. Recommended for those who want to improve sound quality, aspire to be professionals, or want to own a piece of equipment for life. It was originally priced at around 500,000 yen, so getting it at this price is a great deal. If you're switching from another Apogee series, you should be able to transition smoothly. If you're looking for something a bit more affordable, I am also selling an Element 88, so please consider that as well. It is also possible to expand the number of channels by linking this unit with another. I will also include a conversion adapter and a 2m Thunderbolt cable (worth 10,000 yen) to support recent Mac Thunderbolt 3. duet / boom / ensemble / Symphony / one / jam
