I used this without any problems until about two years ago, and haven't used it since then. For this listing, I confirmed that the power and 48V switch lights turn on, but I haven't connected a microphone or PC, etc. The included accessories are as follows: ・Connection cable for the main unit and PC ・Dedicated adapter ・Resource CD ・Japanese instruction manual downloaded from the Focusrite website by me ※I believe the PC software (Scarlett Mix Control) compatible with the interface main unit can be downloaded from the Focusrite website. ※There is no original box. I will wrap it in cushioning material (bubble wrap) for shipping. I will try to ship it as quickly as possible. Thank you.
