Sound in Home Stereo system cuts out

[paprgypc]

I am new to this forum and thank you in advance for your help.

I have a home with a built in speaker system. Unfortunately, I do not have any documentation for the wiring, or the speakers that were used when the house was built. I have taken the cover off one of the speaker and there is no manufacturers information on the front.

Briefly, the system is set up with 4 zones that each contain a volume control. There are a total of 7 speakers in this system. I do not know where the speaker wires come together, but there is a stereo hook up where my receiver is located that has R+, R-, L+, L-. I assumed that this corresponded to the terminals on my Harmon Kardon HK 3600, so I attached the wires thinking I would get great sound only to be disappointed when the sound keeps cutting out. It cuts out at all volume levels, but may be worse at higher volumes.

I have checked out the amplifier and it works fine with my Bose speakers that I used before I had this system.

I have exceeded my level of expertise on this subject and I am looking for some help.

Thank You

Clearly the impedance presented to your receiver is far too low, and activating protection.

If you persist, you will blow up your receiver.

We have no idea how this is configured or what it is designed for.

If you have no experience of this sort of thing, then you need to call in a professional installer.

My hunch is that this system is designed for a distribution amp and not a receiver.
