Members mparsons Posted July 20, 2006 Members Share Posted July 20, 2006 Its not enough that I have to get a power amp, mixer, and speakers, huh? I have to get a crossover! And a power conditioner too. And a graphic EQ. Aggh Anyway, what are good crossovers for cheap? How drastic and what can I expect from say, a $70 Nady crossover and a $200 dbx one?

What do you need? 2 way,3 way,stereo or mono,high and low pass filters,time alignment? And why on earth do you think you need a power conditioner?

Members mparsons Posted July 20, 2006 Author Members Share Posted July 20, 2006 Not a power conditioner but one of those rackmount furmans. Probably a better word is power distributor. I suppose I have no idea what I need. I just learned about these things today Our PA set up ( looks like it will be anyway ) is a Yamaha MG16/6FX mixer into a QSC RMX1850 HD power amp. Channel one of the power amp goes into two Yamaha S115Vs, and channel two of the power amp goes into two Yamaha S118Vs. And of course whatever else I need that I haven't thought of yet Thanks!

Well you should have an EQ. Beyond that and the crossover,that's all you really need. You want a basic active crossover that alows for splitting the signal in the 80-150 hz range with 18 or 24 db rolloff. I just bought a brand new Crate/Audio Centron 2-way stereo model for a smaller system for abvout $60 shipped. Works fine and I'd definitely take it over a Nady or Behr. My crossover in my main system is a Soundtech and it has been perfect since I bought it new almost 10 years ago. Now,why do you think you gotta have that Furman thing? Do you need the slide out lights? Link to comment Share on other sites More sharing options...
Members JohnnyGraphic Posted July 20, 2006 Members Share Posted July 20, 2006 Partexpress had the rackmount power strip thingy for about $20 a few months ago. I bought one-nice & basic. I do miss the lights for. But, as another one of the recent threads mentioned "that's what teeth are for" when talking about the 'flashlight-on-a-noggin' concept.

Members agedhorse Posted July 20, 2006 Members Share Posted July 20, 2006 Beware that most of those power strips are 15 amp devices and if you double-up amps and try to turn both on at the same time, or dreive them hard into 2 ohms, you may have breaker tripping (or worse) problems.

Members Not Serial Posted July 20, 2006 Members Share Posted July 20, 2006 i can pop those "15A" breakers a lot quicker than that, aged. i think all 15A are not equal. avoid the rackmounted powerstrip in an amp rack. i tend to not skimp about x-overs. i'd look at ashly, they have always done well for me.

Members DunedinDoug Posted July 20, 2006 Members Share Posted July 20, 2006 Samson has a couple crossovers that are nicely featured and will not dent your budget as much as the DBX. Link to comment Share on other sites More sharing options...
Members where02190 Posted July 20, 2006 Members Share Posted July 20, 2006 Do NOT plug amps into a Furman. As previously noted, they are 15 amps, and cannot handle the current draw. Other than the convenience of the outlets and the light, these type of units are a huge waste of money, as they offer no real protection or conditioning. Good UPS power delivery is expensive and heavy, but well worth the expense and weight IMHO. YMMV. Link to comment Share on other sites More sharing options...
Members mparsons Posted July 21, 2006 Author Members Share Posted July 21, 2006 Away we go, into OT land! So, what do you recommend for power distribution? This'll be our main rack for our portable PA, so it'll have our crossover, power amp, mixer, etc. plugged in. When we get a seperate power amp for monitors we'll probably get a different rack for it, just for weight purposes. And... who turns on amps at the same time anyway?

I always turn on one amp at a time. But they all draw power when being pushed. Link to comment Share on other sites More sharing options...
Members agedhorse Posted July 21, 2006 Members Share Posted July 21, 2006 I do in my modular racks, but the amps I do this with have inrush current limiting designed in. Commercial rack distribution units are available with a 20 amp breaker and wiring, but not for $20. Link to comment Share on other sites More sharing options...
Members rxnet Posted July 21, 2006 Members Share Posted July 21, 2006 I use a furman PC for FOH which will have eq's/xover/lexicon/mixer and as i've learned here amps are on stage close to the speakers so.... 1. Is the furman OK with that FOH set-up (i like the lights)?? 2. with an amp rack on stage do you just connect it directly to the source (wall)??

Yes and yes but the second yes for larger systems include a distro circuit for each amp rack. Link to comment Share on other sites More sharing options...
Members mparsons Posted July 21, 2006 Author Members Share Posted July 21, 2006 Yeah! Furmans are ok! Crossover? What sucks about low end crossovers that is good about high end ones? And where do you get an acceptable level? Thanks! Link to comment Share on other sites More sharing options...
Members rxnet Posted July 21, 2006 Members Share Posted July 21, 2006 ok crossovers...I've been taught that the DBX 233xl should do just fine in a basic system and you can get one new $160...cheaper on e-bay... Link to comment Share on other sites More sharing options...
