Sub is mute--setup issues?

by philsmith / October 5, 2006 1:19 AM PDT

Greetings all,

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.

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

some recievers have a sub-preout and a LFE output make sure its pluged into the LFE out not the Sub-preout if your reciever has both options.

Sub works--must be AVR issue

In reply to: check this

I tried what Stew suggested and found that the sub definitely works. I've had consistent problems with this AVR and I think it's time to stop trying to fix it and just move on.

I'm looking for a Denon 3805 in good condition. Stewee--any chance you want to sell? HA!

Thanks for the recs, guys.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
