mekabe remain 0 Posted October 10, 2019 Hi, I have a KSW 10 Sub. and it was working fine until recently. There was a change in our room and the sub was moved to another place without any information given to me. I had to reconnect it to my receiver. I did not remember if it was in R or L/LFE connection so I just used the R Then I set both volume and low pass freq buttons to medium. Now the "auto on" feature is not working. In fact, if I plug the receiver when it is active, sub goes ON. But then it does not turn off even after I turn of the receiver. Sub is working , it supplies correct sound when it is on. However, it does not turn on/off. What may be wrong ? thanks. Quote Share this post Link to post Share on other sites
mekabe remain 0 Posted October 13, 2019 actually I noticed that it turns on and off. But it turns on only when the volume is high, or when a very loud bass tone is available. It turns off delayed after turning off the receiver. So , how can I make it trigger faster ? Any adjustment to the low pass freq ? Quote Share this post Link to post Share on other sites
Peter P. 391 Posted October 13, 2019 Use the "L/LFE" input on the subwoofer. Here's the manual to assist you. 1 Quote Share this post Link to post Share on other sites
derrickdj1 8233 Posted October 14, 2019 Leave auto features active It uses minimal energy and protects the amp somewhat. 🌝 Quote Share this post Link to post Share on other sites
mekabe remain 0 Posted October 14, 2019 actually it is on LFE now and it triggers a little late. It requires a bass sound to be triggered. My friend has a Dali subwoofer and it triggers as soon as the receiver is turned on. Quote Share this post Link to post Share on other sites

nitrofan 158 Posted October 14, 2019 Why not? I have subs that have been configured this way for over 4 years with no problems Quote Share this post Link to post Share on other sites

YK Thom 736 Posted October 14, 2019 It may be as simple as to what you are listening to and where the crossover is set. For example sometimes we will just play some music from one of the cable tv music channels, ours rarely engages. However when listening to CDs or internet radio through the Apple TV it is engaged all the time. Some sources may not be going as low as we think. 1 Quote Share this post Link to post Share on other sites
mekabe remain 0 Posted October 14, 2019 so how should be the crossover set ? and why does it turn off very delayed ? what is the normal time for turn off ? Quote Share this post Link to post Share on other sites
YK Thom 736 Posted October 14, 2019 I set my front mains to 60 when listening to music. My fronts are towers. Depending on the source it seems to kick in the first deep notes and stays green. Ill keep my eye on it and see how long it takes to turn off. Quote Share this post Link to post Share on other sites
Peter P. 391 Posted October 18, 2019 Most subwoofers will stay on for a period of time after the input signal is removed. With my subwoofer, it's 5 minutes. Leaving the subwoofer on all the time will draw unnecessary idle current, raising your electric bill. Subwoofers using an "Auto On" feature go into a low powered "sleep" mode after that period of no use, drawing substantially less current. In my case it works out to 3 cents/month.

Emile 3663 Posted October 18, 2019 36 minutes ago, CECAA850 said: Can you substantiate that? Haha ... rough guess is that it draws 10 Watts when left "on" without a signal. That's 0.24KWatt/day ... at an average cost of say $0.10/kWh, that is about 2.4 CENTS per day or $8.76/year Just skip one of your favorite Starbucks latte's (in a YEAR) and you'll break even Quote Share this post Link to post Share on other sites

Peter P. 391 Posted October 20, 2019 On 10/18/2019 at 5:53 PM, CECAA850 said: Ummmm. No. Can you substantiate that? I just measured the current draw on my subwoofer, an SVS-1000. Since it is a recent vintage product, it consumes less power than older, non "Green" energy compliant products. Your subwoofer's power consumption numbers may vary. The manual lists the sub consuming 0.5W while in the low powered, standby mode. Shutting off the stereo, and prior to the sub going into this low powered mode, it consumes 22.8W. So if the Auto-On/Off feature of the sub is not used, it will consume 22.8W while waiting for an input signal versus 0.5W in the Standby Mode. Quote Share this post Link to post Share on other sites
CECAA850 29393 Posted October 20, 2019 They must have changed things then. The SVS and Klipsch subs I've owned in the past had virtually identical draws with the switch in auto or on. Quote Share this post Link to post Share on other sites
