FX-AUDIO FX-D03J, a compact design with optical digital output, and USB connectivity. - Model Name: FX-AUDIO FX-D03J - Input Terminals: USB - Output Terminals: Optical Digital, Coaxial - Size: Compact Design - Accessories: USB cable, Instruction manual Purchased in June 2025. Selling because I'm upgrading to a model with more connection options. I was using it until right before I took it out, so I believe it's in good working order. All accessories (instruction manual and USB cable) are included. The original box is included, but will be folded for shipping size considerations. The product itself will be wrapped in bubble wrap.
