I have a JL Audio E-112 sub that will power on but will not play for several minutes after sending signal. Will play flawlessly after it decides to play. Any thoughts...?

Perhaps it takes a while for the DSP to boot up? No idea. Have you tried contacting JL Audio customer service?

Heard of this before. It could be your output voltage (gain) is too low. If so, the sub won’t kick in until it gets a low end punch to “wake it up”.

Your input signal voltage is too low to effectively trigger a "wake up". To correct this, increase the voltage output level from your AVR (or AVP) and reduce the input gain at your subwoofer's amp to compensate. |

Has anyone successful done what you say to an Emotiva pre pro or preamp? I’ve found that non of their products have had enough power out to trigger any subs I’ve ever owned. |

I'm using a Power Sound Audio XS-15 sub and the XMC-1 triggers it with no problem. Before that I was using a Sherbourn 7030 and that had no trigger problems, either with the PSA, along with a HSU VTF-2 Mk 3 and the Emo XREF-10 and XREF-12 subs. |

Thank you for your response, then my problem is as I suspect ! The length of my cable run must be the culprit. I’ve owned that particular PSA sub! |

Has anyone successful done what you say to an Emotiva pre pro or preamp? I’ve found that non of their products have had enough power out to trigger any subs I’ve ever owned. I haven’t had any problems waking a subwoofer with any of my Emotiva processors. The trick is to not get too low into the negative output voltage on the AVP and reduce the input gain on the subwoofer. That’s really not a volume control...  If that doesn't do the trick... if you're using a coax cable and your subwoofer has dual (L/R) RCA inputs, you can connect a Y splitter to use both inputs. This will also effectively increase the input gain. |

My cable is 25' and since the PSA sub has only RCA inputs, it is an XLR to RCA cable. So it is a fairly long cable run but the XMC-1 still manages to trigger it. |

I appreciate everyone's help. The sub does "wake up" but will not play. I will try the y plug. I am using the xps and dc-1 as a pre-amp

If your sub " does" wake up on command, but does not produce any sound for several minutes afterwards, that sounds like a different problem altogether. You might want to seek the advice of JL Audio on this. |

Though probably not the issue here, I use an actual Trigger Cable with my SVS subs. This turns them on when the rest of the system powers up, even if there is little or no volume, it also prevents that surprise power on when you’re using ‘auto on’ and the LFE channel finally kicks in part way through a movie. It’s an extra cable (or two) but I like the reliable power on and off.
Edit: I now see that JL doesn’t include trigger inputs.

That's an expensive sub. I hope JL audio has good customer service and take care of you accordingly.

The issue is getting it repaired, hence my post. It seems that I cannot locate a live JL service person to to discuss. The dealers in driving distance from me just sell but do not service. In any event, this is/was a great sub. I appreciate everyone's thoughts. Maybe the RS-13 is in my future. |

There is a relatively cheap device that provides a boost in signal for subwoofer outputs. novisnick should be able to tell you what it is. |

You could try disabling the sleep mode (the sub wakes on signal I am guessing) and just leave it on all the time and see if that works.
