Members supersounds dj Posted June 24, 2009 Members Share Posted June 24, 2009 i have a peavey cs800 power amp rated at 400 watts per channel at 4 ohms,can i run the amp in stereo with a 16 ohms load per channel?,what im trying to do is power 4 hf drivers with an 8 ohms impedance on each and rated at 90 watts peak,the 16 ohms load to the amp would give me about 100 watts per channel but im not sure, can anybody answer this? please?

Members agedhorse Posted June 24, 2009 Members Share Posted June 24, 2009 Yes this is is fine, assuming you are really running 2 drivers in SERIES per channel with appropriate crossover. When I see DJ in your name, I must qualify all my answers due to past history with the general DJ mentality. The amp will deliver approx. 140 watts per channel into 16 ohms though and your drivers with their "peak" rating make me wonder if they are of the 10 watt variety. What are the drivers, what crossover frequency, slope etc??? Link to comment Share on other sites More sharing options...
Members witesol Posted June 24, 2009 Members Share Posted June 24, 2009 i'm not sure how you're wiring the HF drivers but two 8 ohm per side parallel will be a 4 ohm load, and 200 watts per driver, probably too much considering the question Link to comment Share on other sites More sharing options...
Members supersounds dj Posted June 24, 2009 Author Members Share Posted June 24, 2009 the drivers are in a pair of sp-4g cabinets that i bought without the internal crossover,i think they are the 22xt from peavey,and im wiring them in series,two in each channel Link to comment Share on other sites More sharing options...
Members kevinnem Posted June 24, 2009 Members Share Posted June 24, 2009 not to be an ass or anything ... just want to be clear. you do know EXACTLY what it means to run them in series, and parrellel right? useally in audio land we use parrellel.

Members supersounds dj Posted June 24, 2009 Author Members Share Posted June 24, 2009 i know the difference between the two, thats why im running them in series,cause i want to get less power from the amp, i dont want to buy a 200 watt amp if i can use the cs 800 with the 16 ohm load Link to comment Share on other sites More sharing options...
Members agedhorse Posted June 24, 2009 Members Share Posted June 24, 2009 That's goingto be a tricky wiring scheme to keep straight... you are aware of this right. The p;ower is pefect for these drivers wired in series. Link to comment Share on other sites More sharing options...
Members dboomer Posted June 24, 2009 Members Share Posted June 24, 2009 Are these gonna be in two different cabinets or together in a single cab? I agree with Andy. It will be a nightmare if they are in 2 cabinets. What are you using for a crossover? Link to comment Share on other sites More sharing options...
Members soul-x Posted June 24, 2009 Members Share Posted June 24, 2009 I don't see how it's that tricky to wire. All he needs is to attach a short series Y-cable or patch panel to his amp. Link to comment Share on other sites More sharing options...
Members Unalaska Posted June 25, 2009 Members Share Posted June 25, 2009 I can see this is going to be a bad experience all the way around. Might I suggest getting something more appropriate for power? PV 2.6C, Usa400, RMX850 (still too big). You're going to be overpowering in just about all scenarios. Back off the HF output to the amp on the crossover. I can't really give any advice more than that. Link to comment Share on other sites More sharing options...
Members supersounds dj Posted June 25, 2009 Author Members Share Posted June 25, 2009 separate cabinets,i need to figure that out now,maybe make a panel and wire them in series that way,thanks for your help. Link to comment Share on other sites More sharing options...
Members dboomer Posted June 25, 2009 Members Share Posted June 25, 2009 For those who know what they are doing ... Peavey recommends using than amp that can put out the peak (160W) rating of the driver in bi-amped setups. In normal use this works fine as there is very little continuous energy in the band that they will be operating. You can toast the drivers quickly if you screw up however. Do your cabs have the sonic guards installed? That adds a lot of protection. If you were using a VSX 26 for the x-over and used a factory preset then youe amp would be fine without hooking the drivers in series. To me the series connection is a bigger risk than the amount of "possible" power. Link to comment Share on other sites More sharing options...
