View Full Version : Leaving Subwoofer On? like.no.other. 01-17-07, 01:45 AM I have a self powered subwoofer and I always keep forgetting to turn it off, is this normal when you leave it on 24/7? I know you people probably answered most of this type of questions, but search really isn't working for me right now. JBLsound4645 01-17-07, 02:20 AM Make a note always turn off the home cinema when not in general use! cneely8 01-17-07, 07:59 AM What about the ones with standby mode? JBLsound4645 01-17-07, 08:18 AM Leave them on! I leave mine on, but I always remember to power up and power down the rest of my home cinema. like.no.other. 01-17-07, 11:56 AM Which one is it?? vitod 01-17-07, 03:13 PM Which one is it?? They're usually powered subs. Any equipment that turns on when it detects a signal. TheEAR 01-17-07, 08:36 PM All the subwoofers I have are on AUTO ON.But leaving a sub constantly on should be fine if the interconnect from the pre/pro to your sub(s) does not pick up any parasitic information. If there is any hum,any noise set it to auto on. like.no.other. 01-17-07, 08:57 PM There is no Auto ON. There is a button and the choices are ON and OFF. It's a powered subwoofer and it's connected via RCA plugs, not wires. bryan.carlson 01-17-07, 10:32 PM Is your sub amplifier class D or class AB? Easy to tell by looking at the back; if there is a heatsink it is likely AB, no heat sink and you got a class D. Leaving an AB amplifier on will draw some power even at idle but only a few watts. Leaving a class D amplifier on will draw next to nothing. This is only a consideration if you're concerned about electric usage though; it won't hurt the amplifier. I leave mine on all the time with no problems. If you're not comfortable with this, shut it off. nitro1max1 01-17-07, 11:40 PM I also leave my subs on all the time. Leave the setting on auto and way you go. OvalNut 01-17-07, 11:42 PM Is your sub amplifier class D or class AB?
