macsmusic Posted June 24, 2009 Share Posted June 24, 2009 hi Can any one tell me why my hk audio deacon system is going into protect mode when we turn the volume up Link to comment Share on other sites More sharing options...
dmoffat Posted June 24, 2009 Share Posted June 24, 2009 Sounds like you are sending too high a signal to the amps. This is used to protect the amps and speakers, being why it is called protect. Link to comment Share on other sites More sharing options...

dmoffat Posted June 24, 2009 Share Posted June 24, 2009 I think more info, such as what amps are being used, would be very helpful. Link to comment Share on other sites More sharing options...

Dj Dunc Posted June 25, 2009 Share Posted June 25, 2009 What inputs are you using, and from what equipment? Could you tell us the level of signal coming from the desk, and whether it is line or mic level. As above, more info please. Link to comment Share on other sites More sharing options...
macsmusic Posted June 25, 2009 Author Share Posted June 25, 2009 We are using a brand new Allen & Heath Desk. Which we set beside the drum kit and ran the drum mics straight into it.The levels are not peaking at all on the desk, yet the PA still goes into protect mode. We changed the Allen & Heath for a Studiomaster 16-4-2 and it still went into protect. JHS has changed all the components and rebooted the software built into the PA modules Link to comment Share on other sites More sharing options...
Simon Lewis Posted June 25, 2009 Share Posted June 25, 2009 I've tried downloading the DEACON manual to find the sensitivity specs, but to no avail. Wretched websites... The MixWiz (for example) is set so that 0dB on the bargraph = +4dBu. If the speaker's input sensitivity was +4dBu, it would take just a small excursion into the orange LEDs to overdrive the amp (presuming that any speaker input controls are wide open). Furthermore, "out of band" signals (e.g. attempting to pass high level, very low frequency signals) may cause the amplifier some problems. Do the amps get hot, or is it just a protection system that comes on? Is there audible distortion? Is it the same for all of the boxes (bins and mid-tops)?

Rob_Beech Posted June 25, 2009 Share Posted June 25, 2009 All seems rather odd. One of the key questions comes from Simon, does the entire system go into protect at the same time? Just one side, just the tops, just the subs, just 1 sub/top? You don't have to have things peaking on the desk to overdrive the amp as others have said. If the system has been back to JHS at all (let alone 4 times) then I cannot see there being issues with the components, for a 5th time. I have to say it sounds like a gain structure issue and you're not realising that perhaps there is 'not enough rig for the gig' tm Rob Link to comment Share on other sites More sharing options...
KevinE Posted June 25, 2009 Share Posted June 25, 2009 You could do with elaborating a bit more. Does it go straight into protect on both sides without producing sound? Does it work for a while normally then trip? Do all the speakers go off? How loud do you / can you play it? How many boxes are you using? Do you use the subwoofers, if so are they still working? Does it make any strange noises before going off? http://www.musik-express.eu/assets/images/HK_D.E.A.C.O.N..jpg Link to comment Share on other sites More sharing options...
Thor_Thunder_God Posted June 25, 2009 Share Posted June 25, 2009 On the allen and heath desk we have set the gain and there is only 1 led or 2 comes on both levels on the desk and the EQ is set to run at only half and we have ran the system with enough head room for it not to be going into protect mode but it still is. Plus the PA goes into protect on satellite mode but goes into protect less often in Fullrange but still hitting protect to much. When we run the tops by themselves there is no problem with the protect coming on but once we add bins it hits protect. Could there be a problem with the limiter in the bass bins causing this ? Another thing is the PA was blasting today when we tried a fun things and was working great but once we introduced a live sound though a full mic up kit keyboards and guitar amp mic it started to slowly start hitting protect mode again that thats with the gain on the desk turned off nearly.

KevinE Posted June 25, 2009 Share Posted June 25, 2009 If JHS say there's nothing wrong then either they're wrong or you're wrong! We really need to acertain which is which. Did they have the whole system back or just bits of it? Is it possible that there's a driver partially s/c so that it's drawing too much current and tripping on thermal? If they're better with the bins, it could be that the electronic crossover in the bins ( I assume you're connecting them this way) is taking the 'heat' out of the signal to the midhighs, meaning they trip less...so that for example a bad woofer in the top cabs wont get so much signal if run in satellite mode. The only thing is that you say both tops are going out at the same time? Surely they have seperate amps and the protection is done in the tops not the bass! Which Deacon setup do you have..3, 4 or 6 box? Have you checked the limiter settings? Are they set too low? Is it actually going into 'protect'...or just 'limit' which isnt the same thing? Does the sound cut out, pop, crackel, stop, fade or just flash a light? I repeat, please elaborate. Could you log in with just the one username to make it less confusing?
