First off, I am not quite sure whether I should post this here in the speaker forum or if it belongs over in the AMP forum. Moderator, please feel free to move it, if needed. Thanks!
I have a Pinnacle Digital Sub 600 hooked up via the sub out to a Denon AVR3801 as part of my home theater. I have a problem with this setup when watching movies where not all the time things are getting blown up, people are yelling at each other, or loud background music with lots of base is being played. The sub falls back into a stand-by mode after some 15 min., but then gets triggered on again when detecting a signal above that trigger threshold. This is accompanied by a loud pop sound. This sound would be acceptable to me if it happened in the very beginning of the movie and only once, but gets pretty annoying when this happens several times throughout the movie – as it does right now. I have set the AVR so that the sub gets “main and LFB†signals. I also set the subwoofer level so that the AVR output is already fairly high. I could not set it any higher, as I had to lower the sub volume already to slightly above min. – otherwise the sub would be too loud. I have been touch with the Pinnacle tech support but they have been fairly slow with responses so far. We already tried a few things w/o success. They said it is impossible to lengthen the turn off timer to greater than 15’ without a drastic redesign on the sub’s preamp. They also suggested to adjust the input sensitivity of the sub.
This is actually my second Pinnacle Sub 600. Pinnacle exchanged my first one with one with a new amp design since the old one emitted a very noticeable humming noise in stand-by. But with the old one I never had any problems with this pop noise during a movie…. Now with the replacement unit this humming noise is gone, “traded†for a very annoying pop noise instead….. I almost wish I had not swapped the subs. But I thought that I could expect some high quality performance for a $1k item….
I start to wonder if there is something wrong with this sub, or my Denon, or whether I really have such a unique set-up (which I doubt)..
Any suggestions/comments?
Thanks!
