wizard 0 Posted December 2, 2006 Report Share Posted December 2, 2006 My amps are now 2 years old and are going to be replaced after xmas. However I cannot make my mind up which to buy... I am currently using Carlsbro and to be honest they have been rock solid, but they are the old type ... I have heard the new powerline series are not as reliable, however that could be duff info. So what do I buy. I would love to be able to afford crown or Qsc.... but unlikely. needs to be around 2kw ( 1k per channel) at 4 Ohms. Before anyone asks, I am replacing them before they pack up and can get some money back on them second hand..... I just like my kit to be under 2 years old ....daft I know. The oldest swinger in town....... probably. Happy Easter.. well I have seen easter eggs in the shops Link to post Share on other sites

DJ Marky Marc 0 Posted December 3, 2006 Report Share Posted December 3, 2006 shaker is almost right, what you realy want is some of the new crown XTi range.... more power, less weight <a href="http://www.djassociates.org"><img src="http://www.djassociates.org/anims/compres_banner.gif" alt="Join the DJ Associates Disc Jockey Association" border="0" width="468" height="60"></a> Link to post Share on other sites
wizard 0 Posted December 3, 2006 Author Report Share Posted December 3, 2006 The Crown XTI 2000 is very tempting....... I might just opt for one of those and keep one of the carlsbro's as backup.

Bolan-Boogie 0 Posted December 3, 2006 Report Share Posted December 3, 2006 Have to be honest the Behringer ep2500's are excellent value for money & virtually bomb proof, based on the crown series and will operate down at 2ohms per channel ! Link to post Share on other sites
Andy Westcott 0 Posted December 3, 2006 Report Share Posted December 3, 2006 Which is good if you are going to load them at 4 ohms - that way the amp isn't working into it's minimum recommended load, and will run cooler and be more reliable. Link to post Share on other sites
Bolan-Boogie 0 Posted December 3, 2006 Report Share Posted December 3, 2006 Good Point Andy, even though some of the manufacturers give their amps power ratings down to 2ohms, i never really fancied it. I always run at a minimum 4 ohms ! Link to post Share on other sites
McCardle 1 Posted December 3, 2006 Report Share Posted December 3, 2006 and will operate down at 2ohms per channel what is the point of 2ohms for mobiles, can never figure that one out as it is 4x 8 ohm speakers per side so 8 speakers per stereo amplifier "The voice of the devil is heard in our land" 'War doesn't determine who is right, war determines who is left, and you wont win this war.'

Bolan-Boogie 0 Posted December 3, 2006 Report Share Posted December 3, 2006 I Agree, although some cabs out there are 4ohm so 2x4ohm =2ohm But wouldnt really be happy to run at 2 ohms for long periods...if at all ! Link to post Share on other sites
McCardle 1 Posted December 3, 2006 Report Share Posted December 3, 2006 and if you are gettin the sort of work that needs 2 ohm loads then you would be running a tri or bi amped system anyway "The voice of the devil is heard in our land" 'War doesn't determine who is right, war determines who is left, and you wont win this war.'

Bolan-Boogie 0 Posted December 3, 2006 Report Share Posted December 3, 2006 Agree !... Its just a marketing ploy to advertise amps at a higher power rating really ! Link to post Share on other sites
Andy Westcott 0 Posted December 3, 2006 Report Share Posted December 3, 2006 Yes, it could be a numbers trick, like PMPO, but I would expect a professional bit of kit to be able to tolerate a 2 ohm load if it states it could. "what is the point of 2ohms for mobiles" Remember that if you bridge a 2 channel amp into a 4 ohm cabinet, the amp will 'see' the equivalent to a 2 ohm load. Bridging is a good way to get some reasonable wattage outputs without using gigantic amplifiers. I'm thinking of doing this myself - a couple of QSCs, each bridged into one of my bass bins. I've long fancied a bit more power on tap, it's just a bit difficult finding financial justification for it. Link to post Share on other sites
Bolan-Boogie 0 Posted December 3, 2006 Report Share Posted December 3, 2006 Makes sense really, just when you get used to the old golden rule of not running below 4ohms... i suppose it just takes a bit of getting used to ! Link to post Share on other sites

Robster 0 Posted December 4, 2006 Report Share Posted December 4, 2006 and will operate down at 2ohms per channel what is the point of 2ohms for mobiles, can never figure that one out as it is 4x 8 ohm speakers per side so 8 speakers per stereo amplifier A speaker presents a varying impedance load to the amp.The figures quoted by manufactureres are normally a "Nominal" Impedance. The big problem with this spec is that the impedance of the speaker changes with frequency. It might well be 8 ohms at 1 kHz, but the impedance might drop to 3 ohms at 100 Hz — low enough to blow many amplifiers' fuses (or worse) when the speaker has to reproduce bass at high volumes. The rating that most manufacturers give is a nominal rating, a ballpark figure that may or may not give you a good idea of whether or not your amplifier or receiver will be able to drive the speaker. this is why having an amp that can drive 2 ohms is a good idea Rob Star EntertainmentsFacebook pagelandline 0161 265 3421Mobile: 0777 99 777 26 Link to post Share on other sites

Bolan-Boogie 0 Posted December 4, 2006 Report Share Posted December 4, 2006 (edited) Shouldnt run the 3 speakers on one amp in stereo as this provides an unbalanced load. you would be better running (if your going to at all) two 8 ohm tops on one channel & a 8 ohm sub on the other, but dont like that kind of configuration..... But im sure i will be corrected here ! :dan+ju: :bouncy: Edited December 4, 2006 by Bolan-Boogie Link to post Share on other sites

spirito 0 Posted December 4, 2006 Report Share Posted December 4, 2006 I'd recomend the QSC amps. I have 3 and wouldnt change them for anything else DJ James Lake & The Shokwaves Roadshow Link to post Share on other sites
Kingy 0 Posted December 4, 2006 Report Share Posted December 4, 2006 I don't like 2 ohms. Far to close to short circuit at full extrusion. Not recommended by many!!. Link to post Share on other sites
