Cannot use 2 pairs (4 speakers) at 8 ohms. This receiver has a minimum of 6 ohms. Using 2 speaker pairs of 8 ohms, the receiver will "see" a total of 4 ohms. This will send the receiver into protective mode - or possibly damage the receiver.
Sorry, there was a problem. Please try again later.Hi there, Thank you for your inquiry. Yes, you can. This receiver is capable of connecting speakers with a nominal impedance of 6 ohms to 16 ohms. Please make sure to set the appropriate speaker impedance for the speakers you are using. Please follow these steps: Press AMP MENU. Press up/down arrow to select “SP IMP.”, and then press OK. Press up/down arrow again to select the appropriate speaker impedance, and then press OK. Be sure that the “8 OHM” option is selected. And also, if the word PROTECT or PROTECTOR appears, there may be an external speaker issue or connection issue that is triggering the protection circuit.
