Purchased last year for studying. I used it once in a real-world setting, but I mainly used it for studying at home, so it's in good condition. I'm selling it now that I'm finished studying. The physical broadcast buttons were very easy to operate. An audio mixer is also built-in. This is not the ISO model. Operation has been confirmed, but cancellations are not accepted. Please check the photos to assess the condition. Shipping will be in the product's original box, wrapped in bubble wrap. The following is a product overview: ・The world's most portable all-in-one live production switcher and control panel ・8 x 3G-SDI inputs support format conversion and full frame synchronization Designed for broadcast, audiovisual, and YouTube live streaming ・The portable all-in-one design is ideal for small venues with limited access ・Features a Fairlight audio mixer, keyer, multiview, DVE, and streaming and recording capabilities
