Purchased around 2011 and used at home for about 2 years. I have only confirmed that it powers on, as I don't have a FireWire-equipped PC. There were no operational issues when it was in use. The main unit has minor scratches, and the outer box has some damage, but the box and accessories are all included. 【Product Details】 - Model Name: Saffire PRO 24 - Brand: Focusrite - Input/Output Terminals: 2x XLR/TRS inputs, 2x TRS inputs, 6x TRS outputs, ADAT input, S/PDIF input/output, MIDI input/output - Connection Interface: FireWire
