I can't believe this thread is still going. Most (all?) chassis amps arrive with no volume control - no problem, use the one on the mixer, that's what it's for. S/N ratios are of little cosequence these days - mixers no longer use nasty little 741 op amps and carbon resistors in the signal path. Burning a speaker out by under-powering it? So if I severely underpower one of my bass bins by attaching a portable CD player's output to it, the speaker will smoke like heck, yes? No, obviously. The RMS value of the vaveform supplied (The equivalent DC level which would produce the

Own goal by the PRS in my opinion. YouTube must be very near the top as regards an advertising medium, and the PRS expects Google to pay them? I can barely believe the stupidity and short-sightedness of the organisation.

I don't think he is the DJ either. In the background can be seen lighting of sorts, probably caught by the camera during an 'uninteresting' phase. I'm not sure about the microphone, but perhaps he was a toastmaster or something?

I wouldn't accept the work, even if local, and that's with my pricing structure! I would politely suggest they enquire elsewhere, or give them 'Arris's number.

My opinion? The disco shop owner should perhaps get himself educated in such matters in order that he will stop giving hideously incorrect and ill-founded advice. You can damage speakers by under-powering them, can you? So unless I run my amps at full output all the time I may burn out my speakers... It is as silly as it sounds, but still these obviously incorrect myths get repeated by those not in the know - I just wish they'd get on with selling stuff/playing music or whatever, rather than pretend to understand something they so obviously do not. Sorry - rant over!

Was booked, but I'm not now. Taking the family out this year and I won't be swayed unless the money offered is unreasonably high...

I still think I'm right, and you're wrong!! :) A 10dB power incease is precisely that - multiplying the power output by 10 - the definition of a Bel. 20dB is a hundred-fold increase and 30dB is a thousand-fold increase. I also think you may be confusing dB with bytes, looking at the strange figures you give, such as 1,024 and 8,192! Let's look at some figures slightly more representative of the real world than the ones you used: 2 speaker cabinets, one having an efficiency of 97dB with 1 watt at 1 metre, and a horn outputting 107dB under the same conditions. It doesn't ma

Yes - let him post, but NEVER post any replies...

Holiday? Can any of you really afford holidays?? I went away to Cornwall with the brats last year which not only cost a lot, but there was then spending money plus 3 lost bookings I had to turn away as I wasn't going to be here. 'Tiz an expensive thing to indulge in.

Look - just give me the flamin' money. What I send it on is my business... OK - nice new QSC amps so I can run my speakers up to their full potential - when the need arises. And some new Martin lighting effects I could do with, as my current lighting is pretty old, tired and not entirely what I think I should be using. There - all gone.

Just come home from Mother's, and I've got belly-ache...

Good point, and yes, efficiency means a lot. However, any decent PA driver should be able to provide reasonable efficiency within its design frequency range, so to my mind the greatest contribution to a speaker's efficiency is the design of the cabinet. There are many different enclosure designs out there, but I group them into three broad groups: 1. Sealed cabinets. 2. Ported (tuned/reflex) cabinets, including bandpass. 3. Horns. Sealed cabinets are rarely seen in bass enclosures for PA work simply because they are too inefficient, and the bulk of typical DJ-type bass spe

Just for the sake of argument, even if such a product did exist, there would be many regularly used tracks which wouldn't appear on there, as they never charted. Buy the tracks you can use is my advice. And I agree with the rest - this cannot be legal so don't even consider it. The quality would be guaranteed rubbish too, if you needed another reason.

Same as Sandy - if short notice I get the client to sign at the venue. I always use a contract these days, as I feel it's the only way to ensure both the DJ & the client have the same details. That way mistakes shouldn't occur. As for deposits, I don't normally take one and so far this hasn't cuased any problems. If I started to get a lot of short notice cancellations I would review the situation, but for now everything's fine.

I won't miss it, as I found too much of the miming to be of a very low standard... I do miss the old style Top 40 rundown, 2 hours rapid-fire on a Sunday, since they stretched it out to 3 hours with a load of useless waffle, but that's another subject.
