I am selling this item due to a system replacement. This is a 3.1CH amplifier that I primarily used. The set includes the main unit, power cord, and remote control. There are scratches and dirt due to it being a used item. There are no operational issues, but as it is an old device, it will be treated as a junk item. Returns, refunds, and exchanges are not possible. Please purchase only if you understand this. - Brand: ONKYO - Model: TX-NR515 - Connection Terminals: USB, HDMI, AV input Thank you for viewing.
