Re: Interesting discovery - receiver "modes"


Maybe the one you would use the most for movies, and a separate BFD program setting for the one you use most for music?

I had a similar experience yesterday when I was doing some testing with 1/12-octave sine waves. (I have a Yamaha, like lovingdvd has.)

Between two passes I played some music, and when I started the second pass I forgot to turn off the DSP, which was “Cellar Club.” This one has always been my favorite for music. I did unplug the front speakers, though, ‘cause I didn’t want the mains mixed in with it.

Well, when I got to 47 Hz, I was getting a huge suckout, more than 10 dB!

Pretty strange. With the speakers set to “small,” the rear speakers (which were the only ones still connected) should be doing virtually nothing! The problem might be that I’m using my main pre-outputs to an external crossover instead of the subwoofer outs. Maybe I need to change that. However, my Yamaha has a switch on the back that lets you opt to eliminate any DSP processing to the main speakers, so there shouldn’t be anything happening from the main output jacks with the DSP turned on.

Regards,
Wayne
