Question about Audio & Video Receivers
Initially, pls do a passive resistance check with all the speakers using a DVM or a VOM. Often speakers would either be 4 or 8 ohms.Thereafter, pls verify that the polarity of the speakers, their speaker wires and how they are attached to the receiver are maintained. Additionally, you may to check for the physical travel of the speaker coil/cone and check if it is moving freely within its confines by lightly pushing and visually checking their action. If all the speakers checks out as well as the wiring and how they are connected, then most likely fault would be with the Denon AVR-486.
To my knowledge, the Denon AVR-486 has 7 separate amps but all of them are rated equally. You may want to cycle the DSP Surround Modes. If problem is common in all settings, then presumably a pair or more of the amps would need looking into. Additionally, you may want to double-check consistency of the speaker arrangements/connections at the rear.
Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information. Good luck and kind regards. Thank you for using FixYa.
