Pull the r.c.a. cable from the amp and turn the volume all the way off on the sub then just tweek it up a little like 1 then touch the center of the r.c.a. plug you should hear a hum when you touch it that means sub is working if it does then your set up on the amp is wrong try setting speakers to large and make sure amp is set up for 5.1. good luck stewee
I've got a Velodyne sub connected to my AVR 1804 (yes, the same one that had a blown surround processor--not once,but twice!)
Anyway, I got it all setup and the only issue is that the sub doesn't put out any bass. When I do test tones to match speaker levels, I don't get one through the sub--so that tells me that the receiver isn't sending a signal through the sub.
Bass comes through on the front monitors, but without nearly the depth that it did with the sub. Is there some reason that the AVR is bypassing the sub and sending bass to the monitors?
In the system setup mode I have speakers set to "small"--which is what is recommended. Sub is "on" and produces it's own EQ sound sweeps, so I'm at a loss.
Thanks for your thoughts on this.
