I bought an inexpensive tabletop mixer, but I ended up using an AG03mk2 instead, so I no longer need this. I will ship it in its original box. Sound output is not a problem. This model does not have a power switch on the unit itself; you need to unplug it or use a power strip with a switch to turn it off. The RCA terminal caps will be included. [Included Items] * Main unit * AC adapter * Power cable * Instruction manual (also includes a Japanese version created by Soundhouse) * Box
