Iam a total noob so trying to explain this is going to be difficult hopefully someone can understand my problem and provide input.
I have a pioneer sc 37 connected to a rotel amp which has been powering 2 polk audio speakers (front left, front right) It has been working fine for the past year. Today when i turned on the receiver my Front left speaker was providing no sound. At first i thought it was the rotel amp so i switched amps (i have 3) but still no luck. Then i figured it was the speaker it self so i switched the cables around(made the right speaker the left speaker) and received sound out of the left speaker. I even went as far as switching cables to make sure it wasnt the cable. So now i know its not the AMP SPEAKER or CABLE. I think its the FRONT LEFT PRE-OUT on the rear of the sc-37 is there a way to test this for sure?
A friend had a similar problem with the SC 35, he unplugged everythiing and decided to test it one more time before taking it to the shop. The next day it worked! I don't have an explanation since he swithed amps, cable and swapped speaker inputs the day before.
