Question about Boston Acoustics AVR7120
Hi, Sounds like the overload protection is cutting in. What impedance speakers do you have connected to the A and B speaker connections? If the impedance is too low the receiver will try to output too much current and the system will overload.
Also what volumes do you listen at? Is the receiver hot to touch before it shuts down? Check all your speaker wire connections and make sure no wires are touching other wires or speaker terminals at the receiver end and speaker end. What size speaker wire are you using?
It might be an issue but I have heard of problems like this when they used very thin wire. How long are the wire runs? Do you have any 14ga. wire you could try? 16ga wire should be the min. you should use on very short runs (unless you are using HTIB speakers).
I don't think the wire is an issue but I have heard of problems like this when they used very thin wire. How long are the wire runs? Do you have any 14ga. wire you could try? 16ga wire should be the min. you should use on very short runs (unless you are using HTIB speakers).
No Surround Speaker Sound
If your surround mode setting is set to "Stereo," your surround speakers will not function. To remedy this, just change the surround mode. Push the "Surround Parameter" button either on your receiver unit or the remote control to access the surround mode settings. Push the "Select/Enter" button on your remote control to cycle through the surround modes: "Direct," "Stereo," "Dolby Pro Logic," "Mono Movie," "Rock Arena," "Virtual Surround," "Matrix" and "Video Game." Select any option except for "Stereo."
Makes sure that none of the speaker wires are shorted across the terminals at the speakers or at the amp. Just one stray strand can cause an amp to go into protection.
