Yeah, read about it before - I would use the +10v as relay-trigger-output for the 380v-DJ´s-balls-clip, that should be work!
The sound when in "protect" could be as bad as possible, together with the ball-clip, äh red-light, even the last idiot should recognize whats on! Last questions here. 1.) do ya use it in the monitor-path as well!? 2.) Why companies like BSS built in things called "limiter" if they don´t work as a limiter should be!? Would be "soft-limiter/watcher" not the better designation |

This was my biggest issue with it really, if the DJ was stupid enough to not realise that pushing the mixer hard into the red is going to sound crap then they certainly didn't understand (or want to) that turning it up more made it go quieter until it eventually sounded a bit like a bad MP3. Also, a lot of promoters seem not to care about the reason why the rig sounded weird and quiet for the headliner's set, just that it did and that can potentially cost you work. A Drawmer SP2120 does the same job, with a cleaner effect to my ears, but keeps the volume at the same level rather than reducing it. That makes it more or less just a limiter, and one that you can leave wired in without having to take the time to explain to each DJ or the promoter how it works. |

Thats why I ask if ya put a second unit in the monitoring-path as well!? I would set the second then a bit more "aggressive" then the main-one so se dj will notice (I hope so). Finally the "better" the person behind the desk the better will be the sound at all but to many idiots outside these days! |

Use http://www.sengpielaudio.com/calculator-db-volt.htm To convert input sensitivity (VRMS) to dBu, and use that to answer your question... post again if you are still stuck! |

If your amplifier input sensitivity = 0.77 VRMS = -2.27 dBV = -0.052 dBu
Correct? How to convert this -0.052 dBu in dBFS for set the limiter in DCX2496? -19.8dBFS : 2.2dBu = x : 0.052 dBu I have to find the X? Thank you Edited by massisoda - 30 September 2010 at 4:19pm |

You are nearly there. Once you have the sensitivity in dBu, just remember that 0dBFS on the Ultradrive = +22dBu. The equation to give you the answer: (Amp Sensitivity in dBu) - 22 = (Meter Reading on Ultradrive in dBFS) So... 0.052dBu - 22 = -21.948dBFS |

They should be, thats what they're designed for. We've had this discussion before. Probably fair to limit the DCX well before the amp clip so you get a bit of headroom for the poor amps. DJ's tend to 'ride' limiters meaning the amp will spend all night just below clip. |

The limiters on the dcx also often don't go low enough...

Yep that's right. For maximum safety use the maximum release time. Shorter release times will make the limiter behave like a compressor. The long term average level will increase if the system is driven hard into the limiters. For live music you'd be ok with a shorter release time. |
