Powered Sub question. (1 Viewer)

[David Preston]

My sub is connected to my receiver by a sub cable. I normally have to turn the sub on every time I watch a DVD or something. If I leave my sub switched on in the back of the sub when I turn my receiver off will it turn the power to the sub off? Meaning I can just leave the sub swith on and don't have to reach back there every time just turn on the receiver and the sub has power.

If your Sub has a switch that says On/Auto/Off, then leave it on Auto. It should go into standby after a certain period of time with no signal and turn itself back on when it senses something on the line.

Check you Sub manual.

If it only has ON or OFF, it won't turn off when your receiver is turned off. As Paul said, if your sub has an auto mode, this will work best.

Even if it doesn't have an auto mode, just leave it on all the time. It'll draw so little power that you won't notice a difference. I have a pro amp that I leave on all the time.

DAVID IS THERE A LED LIGHT THAT GOES ON. THE REASON I ASK IS THAT ON MY SUB THE LIGHT GOES OFF IF THERE IS NO SIGNAL GOING IT AND THOUGHT IT WAS OFF BUT IT WAS IN STANDBY SO I WOULD PUSH THE BUTTON AGAIN AND TURN IT OFF THINKING I WAS TURNING IT ON.

You guys know exactly what I'm talking about. I do have on/off/auto. I also have a red/green light. Reason I ask this is because the other day I went to turn it off and the red light was already on. I guess it was on auto. I wasn't aware that it would turn off by itself. How long is the wait for it turn off by itself? Thanks everybody.

David,

It differs from one sub to another, but I would figure it's probably 10 minutes or less. Just leave it in auto mode if it appears to work properly that way.

BTW, tell us again which sub you have. Isn't it a Cerwin Vega? If so, what model # is it?

 

[David Preston]

Brian, it is the HT-S12A self powered sub. It is ported bottom firing. I don't know how many watts right off hand but I'll go to the CV site to find out. Brian on my other post you said it would be cheaper if it was black and not finished for the one you would build be. Thats sounds good to me I prefer black anyway it will match my other stuff much better. Thanks

Hey I was just seeing if the auto worked. It does not come on when I turn the receiver on. Tried turing it to tuner and also DVD with movie playing sub does not come on automatically. What could the problem be?

 

[Brian Bunge]

David,

It'll only come on when the receiver sends an LFE signal to the sub. Also, if you've got the sub's gain set too high and the receiver's gain set too low then the auto on feature may not work properly.

BTW, a 12" sub rated down to 30Hz isn't very promising.
