    My powered sub can be on, off, or standby (auto on). I've had to play it lower due to my new home location, so if it's on standby it doesn't come on. Is it OK to leave it on all the time?

    One solution could be to use the 12V trigger on a receiver to power the sub on when the receiver comes on....just a thought...

    Hi

    To deal with the 'auto on' not coming on, due to lower listening volumes
    Lower the volume on the sub
    Raise the sub volume in the receiver.
    You'll need to re calibrate the overall volume after performing this.

    This has worked with some receiver and sub combinations with the auto on problem.

    Hope this helps

    Paul has the technique[​IMG]
    Auto On feature is a nice convenience when it works; the sub amp idles way down, just like some other rcvr/amp/VCR components using very little power at all on standby, until an audio signal wakes it up.

    I have not turned my sub off in over a year.

    our sub doesn't even have a power switch.

    I live in a duplex and frequently cannot use my sub[​IMG], so I leave it in the "Auto-on" state and change the LFE output through my receiver.
    If I want the sub, I change the LFE Out to Sub, otherwise I leave it on Mains. If I further want to reduce Bass, I set my Mains to Small[​IMG]. If I want to reduce even further, I turn on Dynamic Compression.
    This is all done with the remote and no need to mess with any of the bass settings or levels. [​IMG]

    Mmmmm....Derek, do you have any links to that 12V trigger you mention? I imagine it's a device that sits between the sub and the wall, with a connection to one of the receiver's AC outputs, so that the power is drawn directly from the wall but turned on with the receiver.

    I always wondered if such a thing existed. I also always wondered how such a thing would work. It's straight forward enough for all the power to go through a switch (like a light switch), but to have a low power trigger cause another high power circuit to close...never quite got that.

    I will also try Paul's technique. At least I'm relieved to know that leaving it on doesn't hurt the sub. Thanks!

    Many receivers have a 12V trigger line - it switches on when the receiver comes on and off when the receiver goes off.
