Compatible with Onkyo TXSR875 TXSR876 AV Receiver, CRN755 CD Receiver. HQRP AC Power Cord is normally used to supply power directly both to the device (if a corresponding DC-IN is available) and to the AC DC Power Adapter which will then be connected to the device. To avoid any misunderstandings, please check your device if the AC power cord is connected directly to the device or to AC DC Adapter. Please note that AC DC Adapter is not included in our offer, it should be purchased separately.
