I need help ASAP -I'm getting phone calls left right and centre...:( :confused:
Read other thread Charlie. If they people are being sick you must have had them way to loud or everyone had a bad buffet.
No, there wasn't any food - admitally I had them loud (clipping at some points) but the sound of them was just laughable ... like parrots.
I can't believe people are going to hospital, or being dizzy and having nose bleeds etc
Volume can be dangerous just because something can go that high doesn't mean should run them that high. I had a pair of mackies and in the 4 years I owned them never once let them clip or even came close.
Prehaps you should read this http://www.hse.gov.uk/noise/employers.htm as the person in control of the volume you could be held accountable should damage have occured.
It could just be a bug that's going round. I feel really I'll at the moment and I haven't been anywhere near loud music or dodgy Mackies!
Your PLI up to date? lol, why you clipping the life out of Mackies for 12 year olds you muppet lol.
Hmmmmmmm.... as someone who suffers from positional vertigo (i.e. I get dizzy without warning) and has been for every test on the planet and is extremely susceptible to anything which can make you dizzy. I can honestly say that volume doesn't normally have an impact on me. Bear in mind the inner ear is responsible for balance, and that's normally more affected by changes in temperature, alcohol, etc than it is by Sound Pressure.
By the way, I've just been told that the kids at the 13yr olds birthday party one of my guys did last night were drinking alchopops!!

Quite unbelieveable, because I've heard SRM 450s V1&2 in a variety of setups, often driven hard, and they never sound 'appalling'. They must be faulty.
Agreed. Even when I've done no EQing to my V1s they sound nice. Scoop some of the mid out to make it less harsh and they sound lush.Quote:

How do you get yourself into these situations?
Would suspect that the speakers are unlikely to be the cause- never heard of it in my time doing mobile work or crewing for gigs.
The question arises that if they sounded terrible why were you pushing them hard?
sound like you have your out put gain is way to high.
also did you get the speakers new.. Sound one could of changed the driver with some crap and sold them on.
Set your audio in your house and test them..
Not familiar with Mackies - but is there a mic/line in button, and have you selected the right option? Just a thought as on my actives, this can cause a nasty din!
Charlie, following on from what soundtracker said...
How far up did you have the volume/gain dial up on the back of the Mackie's?
The SRM450 is a loud cabinet anyway. I have never clipped any of my Mackies and even with out doing so they are still pretty loud.
You must of been running some serious volume to get them to clip??
I think it is much more likely that people in a confined space have caught a virus from one another. I have heard of sound causing temporary deafness but never nausea and I have been in the business for over 40 years. Lighting is much more likely to disorient than sound. If it wasnt for your Dad being ill then I would say you were being wound up. Stop pannicking and start thinking logically. Are these people ringing you up accusing you of causing their illness? If so they need to visit a doctor/hospital and get medical evidence of their condition and put a written claim in against you which you can then pass to your insurance company.
As for sound generally. My equipment may be old and unfashionable but the quality of my sound is superb. Dont run things into clipping and distortion - its not nice.
CLIPPING Charlie.....my god these must have been wound all the way over.....Quote:

These must be of been turned right up. :eek:
The amount of times I have done large school fields and needed the output from the V2's, I have never clipped them at all.
As Tony has said, 12 oclock, this should be maximum for the work you guys do.
Right,
Literally just woke up - calm - tea and pancakes at the ready. :approve:
At the start of the night, when I had a few minutes to spare, I was messing around with different songs, because I had literally never used the Mackie's before in my life.
Baker Street sounded great, until I notched the mixer up, and it sounded a bit squarky. (The dial on the back of the Mackies were at 12 o clock)
Anyhow, playing different tunes, I came to the conclusion I defiantly needed a bass bin ASAP.
I admit, it was very loud and at certain points throughout the night the red light was permanently on (until I noticed and notched the mixer down)
Standing behind them wasn't so bad - and when a member of staff went white and said she had to sit in her car outside, we all put it to her having a bug.
Then Dad called and told me he had been violently ill everywhere, which was very odd, because he was perfectly fine an hour ago.
I have spoken to the people who were a tad concerned and they are feeling better today. My ears have stopped ringing and I'm no longer in pain. When I turned the volume down at the end of the night (whilst packing away) I realise how loud it actually was - like, mind blowing. It's all bad habit - I'm a regular at this school, and my old setup always used to verge on clipping, so I guess I presumed it sounded pretty much the same.
I think my problems were:
I didn't know how to set them up properly (EQ etc) My old speakers didn't really need a tweaking.
They were far too high on the stands, so it was sounding top heavy.
It was in a drama studio with carpeted floor and (sound absorbing things?) on the walls?
In Iraq sound is a weapon - Due to my error, so were the Mackie's last night!
Its always hard to tell the volume level behind the decks, you need to go out and check during the night.
If you were clipping them and had the red light on for a lot of time Charlie, you really need to limit yourself. I owned Mackies and they are loud, but there is no need for that to happen. Full stop. Sorry, but I think it's rather amateur of you to run speakers that hard and it's things like this that get us a bad name.
People wouldn't be ill cos of a pair of speakers either.
I wish you'd slow down and think about what you are doing. Listen to speakers in different places and get used to them rather than just blasting them out.
I wouldn't go that far. They aren't THAT loud. It couldn't of sounded unbearably loud as I still had a full dance floor regardless. A lot of the sound was absorbed by the thick carpet and the things on the walls.Quote:

I wish you lot had heard them - it was really squarky - even when turned down.
The mind can do funny things and in doing so unbalance the body. I personally felt sick.
Sorry Charlie, but I really don't the speakers will have had anything to do with it.Quote:

It sounds like to me you really need to reign in the volume. I remember when you helped me you said you ran your speakers a lot louder....;)
Oh, I wish I could explain myself.Quote:

I believe Tony had just spoke to Dad (thinking it was my mobile) and Dad has explained to him the noise and how it made him ill.
Was it the same coming out of both speakers? Was there any bass at all? I'd start checking the mixer - what mixer do you use? Possibly phono outputs used, crossover frequency set, kill buttons or eq, filters? All obvious things I know, and you've probably checked them already but always best to start with the obvious and work up.......
To be fair it sounds like that anyway. :sj:Quote:

Good to see you didn't permanently damage any punters though Charlie, chin up, on wards and upwards mate.
You actually need these nights as part of the learning curve.
When I first started I thought I was invincible....
Until I turned up for a Wedding with only Amplifier!!
The rest is History.......and still part of my worst nightmare.
You'll identify the problem....and you'll make sure you never make the same mistake again....hopefully!!
It wasn't actually a 'mistake' as such, but I was at a gig - had set everything up and was ready for a sound check.Quote:

Anyway - started the sound check then all of a sudden the Mackie's cut out... So I though ahh :Censored: there's not enough power getting to them! Anyway, 20 minutes went by of running around finding different power points, changing cables etc. Finally, I checked the back of the cabs to find that someone had pressed the timed cut-out button :bang:.
Once worked in a venue that was "Pre-facelift". ;) ;) ;) ;) Five 13amp wall sockets, but none with any power! :bang: :bang: I had to share with the one armed bandit. :eek:Quote:

I'm getting the wave of nausea again....just thinking about it.....
That sounds pretty accurate, Martin ;) :DQuote:

Just a thought, Was the Contour button on the back of the speakers pressed in or out?
CONTOUR EQUALIZATION
Adds a gentle (3dB) boost below 100Hz and above 12kHz. It's handy when the SRM450 is used as a recorded music playback device. In live applications, it also provides extended bass and high-frequency performance without requiring you to excessively increase SPL levels.
That may help.
I'm assuming you bought the new V2 Mackies, did you realise they have 2 switches on the back, one is a 'conture' switch that boosts the high and low frequencies to 'brighten' the sound, the other is a low pass cut, it cuts the very low frequencies, have you got these set suitably?
Should the buttons me out or in? I had them out....
I'm not sure, try them in both positions
Should have been fine then.Quote:

I did..(nice guy BTW :) )..he also said you didn't have enough time to sound check - you really need to do this (from the other side of the booth). I take 3 sound checks. Low, Med and High.....I've never got to high....but I know where it is.Quote:

Low frequencies are far more likely to make somebody ill, although I believe that it would have to be considerably lower than that given off by your average disco system.
I agree - I think that a continous tone around 6 or 7 hz played at extreme levels (I'm talking ridiculous aircraft hanger size system) will make the average human lose their faculties causing uncontrollable vomiting and a release of the bowels.Quote:

P.S I was told this as part of an amusing acoustics lesson where we discussed using sound as a weapon and i'm sure a fair amount of creative licence was involved! Tony A1 could perhaps enlighten us as to the exact facts?
I was just thinking the same thing. I also have the mackie V1's as well as the swa 1501 subs & have never sent them to clip and as for the sound making guests ill....utter twoodle! More than likely a strobe or similar left on all night.Quote:

Just a thought.....you weren't using an amplifier to drive these actives were you Charlie, you did run a line level signal directly from your mixer, not an amplified signal from an amp ? I'm only asking coz this would definately cause the 'squarky' sound you experienced and nobody has asked. I just want to make sure you fully understand the concept of active speakers?
I'm probably wrong but it's worth asking, yes? :)
As for the people being ill because of it........pile of male cow crap!!
Yes yes, two xlr's from my mixer -
I seriously think people were ill due to them (because I did myself) or maybe the lighting - the room was pitched black (drama room) so they had greater effect.
Good! :)Quote:

The lighting?.....more likely, that combined with the smell of sick and a kind of hysteria, that could do it?
