Turning volume up max turns on prot. mode
When I turn up the volume on my receiver to very high levels, it enters protection mode.
Here's the setup:
Onkyo, 100watts per channel, min RMS, at 8 Ohms
Feeds from Channel into Sylvania Impedance-Matching with 8 pair speaker selector, 150W per channel.
Goes out to to 2x JA Audio , 8 Ohms each per room selector, 10 to 100 watts power handling efficiency handling 1w/1m at 90db.
I have bookshelf speakers that I can connect to the receiver and turn up to high volume. When I play through the selector, I have to turn the volume WAY up to get satisfactory sound.
Lately the receiver has cut in and out with protect mode when the volume gets very high through the selector. Protect mode hits for about 2 to 4 seconds and then outputs sound again.
No heat coming from unit. Lots of ventilation. Checked for shorts.
Could there be too much power drain on the receiver to the speaker selector at very high levels?
I have troubleshot most of the other variables.
I've been looking into wattage, impedance, shorts, components, etc and it doesn't seem to be there.
