Maybe not a good idea openly advertising a link to them if you are seriously thinking of buying them, especially as there is only one pair available, and loads of DJ's love a genuine bargain....... :msn-wink:

These? http://www.mcqentertainment.co.uk/index.php?main_page=product_info&products_id=2307 The spec sheet is here:- http://www.altoproaudio.com/downloads/black/spec-sheets/Black15_Specsheet.pdf According to the manufacturers datasheet, the Max SPL is 134db. Nearly 29kg per cab though, so make sure you stock up on porridge and weetabix :yes: No i've personally not heard them, (for most gigs I use the same ones which you are upgrading from). But with that wattage and SPL it seems a good deal, especially as they retail for around £800 to £900 per cab. I'm thinking that th

Yes, it can do. I know its generally accepted that in a lot of cases, a 350w 130db speaker can sound perceptively louder than a 500w 96db speaker, when used in the same application with the same material. Lots of people generally assume that watts is the be all and end all of speaker design and if its not loud enough lets bring in more muscle in the form of upping the power and crank up the watts!, but its a bit more complicated than that, and whilst watts does play a part, its not the end of the story, and SPL ratings are just as important, and its no use just upping the wattage, if the SPL r

Well, if a choice between the JBL and the RCF then I would be choosing the RCF, but thats just my personal opinion. Also look at the FBT MAXX range, these are expensive new, but can sometimes be found second hand in good condition for around the price you are looking to pay. When comparing speakers, don't just consider the wattage, but also the SPL figure. This is an indication of how efficient the speaker is at turning the raw power from an amplifier into actual sound pressure which can be heard. The higher the SPL, the better quality and more efficient the speaker is. So for example, a 5

Personally, i'd throw a bit more into the budget and go for the QSC K12. 1000 watts RMS of punchy power per cab packed into a speaker physically similar to the size that you have now seems to be a decent and worthy upgrade in my own opinion. I'm not a fan of JBL personally, i've never auditioned the speaker in question, but I haven't really been impressed by the sound from various other models in their range.

Probably Electrical Interference. Remember the days when you used to flick a light switch and you got a crackle from a nearby radio?, this was more often a problem on LW or MW frequencies and doesn't occur much these days with the widespread use of FM and DAB, but hopefully you get my drift. Anyway, this crackle is caused by the sudden surge of electricity whenever anything is plugged in / switched on, and this can cause delicate computer equipment to crash or operate strangely. Generally its good practice to keep supplies for your lighting and audio separate, rather than sharing the s

From the brochure, it appears that the mixer has two dedicated monitor outputs, marked as "Mon 1" and "Mon 2" which work at line level and are suitable for driving amplifiers or powered monitors. The volume to these monitor outputs are controlled by the rotary control marked "Mon" which can be found on each input fader channel. So the easiest and simplest solution would be to use one or two low to medium powered monitor speakers which have built in Amplifiers. Plug one of the powered monitors into the "Mon 1" jack output and the other into "Mon 2" jack output. However you wouldn't need to

Always be cautious about buying components from Ebay, a lot of Chinese Counterfeits and blacktopped components find their way onto there. Sometimes its worth paying a little bit more and getting spares from a Franchised catalogue distributor, just for peace of mind. There is nothing worse than carefully de-soldering components and refitting new ones only to find that the 'new' component fitted is a fake or a blacktopped version of something completely different, and having to go through the process again.

Its possible to cause static damage through soldering, but more likely to occur if handling components prior to fitting them to the PCB. In most cases soldering iron elements and tips are grounded through the electrical earth connection. Its probably more likely that you have overlooked a ground connection somewhere, did any of the screws holding the PCB have a crimped terminal with a wire connected, under the screw?, or washers which made a physical connection to any metal PCB stand off pillars?. Is it possible when re-soldering, that you accidentally bridged two joints together with a so

Sorry I don't, in all honesty I haven't heard or used those speakers. DB Technologies have a very good reputation though, so I would imagine that even their budget range would sound a hell of a lot better than the best budget speakers from other manufacturers, so its a reasonable gamble. Why Buy New is also a good dealer, i've yet to buy any 'B-Stock' goods from them, which haven't arrived in pristine condition, just as good as buying new :msn-wink: Yes, that is good advice and the majority of experienced Dj's will agree on that one. Clients won't notice (or care) if you don

Depends on the size and capacity of the venue and the quality of acoustics within, and also how they are going to be positioned. Are they going to be mounted on stands? or flown from a rig?, or are they going to have 200 solid bodies dancing directly in front of them :shrug: All of these factors will affect how the speakers sound from venue to venue and how well they will cope. Personally, I think that, unless you are working a large venue then these speakers, plus the addition of the sub will easily cope with the type of work that you are doing - more so if you stand mount them. Ther

Well for what they cost, if might be worth replacing both amp IC's on the master output pcb. Have you tried gently flexing and tapping the master pcb to check for dry joints and track breaks?, these can cause intermittent faults. If you have a digital multimeter I would attach it to the PSU and monitor the supply rails to see if there is any sudden voltage drop or fluctuation across one or both rails whenever the fault occurs.

Depends on how upfront and personal you want to get with the circuitry and what test equipment you have available to you for indepth fault finding. If its happening across all channels, then yes the master output is one possible suspect but if the fading happens on both L & R channels, then it would be more than a coincidence for both sections to fail with the same fault, as I would think that there would be two amplifier IC's driving the master outputs - one ic and associated circuitry for the left output and one for the right output, even if they share the same pcb. In these types of mix

Does the fading in / out happen across all of the channels?. If you haven't done so already, try to plug your music source into one of the other channels. PA Mixers have inputs for a wide range of equipment to its channels, make sure that you are connecting to the mixer using the line level option, as opposed to a mic, instrument or phono input (This may appear obvious but you would be surprised how often it gets accidentally overlooked smile icon )

The pictures are OK. It seems that the speaker cables use 6A Flymo mains lead you can't beat that bright orange colour for use in low light venues. I've seen this used many times before!. Everything seems to be connected OK, I can't see any wiring related reason for the fading in / out problems, but it may be worth changing the cable you use to connect between the mixer and amp, just to rule out internal breaks and bad connections, shouldn't be more than a couple of quid and its useful to have a spare anyway. Also turn up the volume on the amplifier to at least 1/2 to 3/4 travel on it

It will probably be better to upload them if you can, since somebody else may spot something which I miss. However, if you have no option but to email them, my email address is below

Sure. I'm not sure whether you are able to upload images directly to the forum being a new member. If not you can either link to images hosted from your own website or Flickr album, or use a free image upload site, such as http://postimage.org/ http://tinypic.com/ http://hostmypicture.com/

Virtually every single offer of work on that site is for £60 or £70!. £60 for a residency with no equipment required is marginally better, but it is still a lot less than I would expect a city or town based venue to pay for experienced DJ's, especially if its an established club or venue with a large-ish capacity. Lets face it, the DJ and the music he / she is playing is the only attraction in a club and therefore should be considered an investment. £60 doesn't seem to be a good reward for the DJ and the experience which is effectively bringing people in from the street and keeping them th

On your opening post you mentioned that the Amp went into 'Protection Mode', normally when this happens the relays inside the amplifier disconnect the load (speakers) and the sound goes off. This can happen for a number of reasons, usually a short circuit or a failed speaker driver, internal overheating or a DC Voltage appearing at the speaker outputs. If this isn't the case then its unlikely that the amplifier is detecting a fault, there may not even be a fault if the speakers don't disconnect. A lot of amplifiers have two speed or even variable speed fans which react to the internal

£60 - £70 is the average amount of money which is being publicly offered for the work advertised on the link that you gave. For example:- http://agencyofsound.co.uk/showthread.php?113717-Uckfield In fact there is a whole list of 'DJ's Wanted' opportunities, all roughly offering the same fees - 1340+ pages of them on this link, all at different venues up and down the country and, strangely, all offering exactly the same fee scale...... http://agencyofsound.co.uk/forumdisplay.php?4-Dj-Vacancies As you have already said, its £40 for you just to hire the Van, you have to also pu

I suspect the Amplifier has developed a fault. For two seperate speakers to develop the same fault, at exactly the same time is pushing coincidence. How are you wiring the speakers from the amplifier and with what type of cables?. They should each be wired with a single lead - with either Jack Plug or Speakon connectors fitted to each end. The left speaker should be connected to the left hand channel output of the amplifier, and the right hand speaker connected to the right hand channel output at the amplifier. If your amplifier has a switch on the back marked 'Bridge' or 'Bridge M

Sorry, i'm not familiar with that amplifier. Do you have a link to a website with it on? so I can check out the technical specification Could be a number of possibilities. I guess prior to the amplifier cutting out, that you do get some sound from the speakers? and that they are both working?. Does the sound that you get prior to it cutting out, sound clear and ok or is there any distortion or cracking.

Unfortunately the days of ringing an agent, getting placed on their books and sitting back and letting the work roll in, have long gone, such is the competition and the fact that Dj's are generally now considered ten a penny all leads to the fact that these days Agents generally seek out new and creative talent and will come looking for 'you'. In a lot of areas, the number of available DJ's exceed the number of available gigs, this means that competition is fierce and its basically a buyers market. A genuine agent will want a track record and references of clubs / pubs / venues / agent

£60 - £70 a night, seriously?. I'm all for freedom of Mobile Dj's charging what they think they are worth without criticisim or ridicule, provided they can realistically run a fair and legit business based on those earnings, but if 8000+ venues all over the UK think that £60 - £70 is all that the entertainment industry is worth then I weep for the future :sad: . £60 a night sounds a lot, until you add all of the expenses of running a business into the equation. Once you have bought the equipment, bought a music collection with regular updates, purchased any license(s) required, paid for pu
