I'm not sure if this is the correct place to post this question, but since I am driving Polk speakers, I figured that I would give it a try.
I sat down to listen to some 2 channel music this evening and shortly after turning the system on (3-4 seconds), the left channel stopped working and the "Current Overload" indicator on channel two (on the AMP) remains lit. At the time of the "event", the volume was set to about -15.0 and I was in the process of taking it down to -20.0 (it seems to me that the left channel stopped working as I was going from -15 to -20).
My current setup is Denon AVR-3805 as the pre/pro; a Parasound HCA-1205A as the amplifier driving 5 Polk Audio LSi-9's.
I am using Cobalt interconnects and Cobalt Ultimate Speaker cables to connect to the Left, Center, and Right channels. Immediately after the event, I verified that all of the connections were solid with no cables crossing or touching each other. I then did the following in an attempt to troubleshoot:
1- turned the AMP off and then back on ... indicator remains lit on channel 2.
2 - disconnected Channel 2 input and outputs (after turning the amp & source off) ... indicator remains lit on channel 2.
3 - disconnected all connections to the amp (after turning the amp & source off again) ... indicator remains lit on channel 2.
4 - connected the Left LSi-9 to the channel 1; this was just to verify that the problem was not in the speaker. Channel 1 (output) continues to work.
So my question is could it have been the LSi-9 which has left the Parasound in a "Current Overload" state (btw, in this state, the channel does not produce sound)?
Can I expect this to happen again and/or is this a common occurance (this is my first experience with an external amplifier which I purchased used about 2 months ago and it has been working perfectly since then)?
Does anybody have any experience with the "Current Overload" state and is this something that can only be fixed by a Parasound Authorized Service Center?
Thanks in advance for any/all assistance.
