High level input


From my Mcintosh MC352 I am running speaker cables to my PD80's then jumping to the high level inputs of the built in sub amps. If, for example, the MC352 is pushing 200watts per channel, is half or that power being used to signal the sub amps? Am I wasting power just to send a signal or do the sub amps somehow filter out a line level signal? I hope this makes sense.

Thanks in advance.

If you can set your MC352 power meters to measure peaks, you might do that, play the same AC/DC track and do another measurement. If the 99db reading is correct, then you might expect to see peaks somewhere between 2-4 watts on the MC352, accounting for the db rolloff at 14'. If the 122 db reading is correct, then you might see peaks over 260wpc. Big difference. The MC352 power meter reading in conjunction with your DEQ2496 and Extech readings should give you a better idea which decibel reading is more accurate.
I actually had the red peak lights flash on the MC when I did the test. Both meters were running with the peak hold activated. The MCs needles were almost stuck at the high end of the scale. If the meters on the MC are accurate I would have been pushing the 350 watt per channel envelope. I know it doesn't seem right but that's what I am reading. Maybe I am doing something wrong. You would think using pink noise would be more stable and give you a more accurate reading, but I dont really want to hear 120db of it.

My room may play a role in all of this as well, you'd have to see it. Custom built home with a WIDE open floorplan.
Something doesn't seem right. There is no reason why the MC352 should ever be close to clipping with 101db/1w/1m loudspeaker, unless you're trying to fill a barn sized space to 124db levels.

I think you should call Ty and explain what's going on and what you've done to test the system.
It surprises me that I am getting such low readings, but believe me it is VERY loud, However, I agree, I will call Ty and report back.

Thanks
Congratulations!
You two have just won the Golden Propeller Hat Award!

We have yet to get it "goldened" but I assure you that it is in the works (right after cryo-treatment).
