NY_EE AL-III + system.

Here's my main system. See photo for equipment list. The center channel speaker is just a crappy Sony mounted above the screen. I was seriously looking at the custom center on eBay but it's just too expensive. My son's cars are all over the floor in front of the screen in the theater shot. I have an NEC CRT projector operating at 720p onto the 120" screen.[

Re: NY_EE AL-III + system.

Nice system. I have been watching that center out on eBay also. Would love to have that but it is too much for me right now also.
Some cool Carver stuff!

Re: NY_EE AL-III + system.

I have another pair of Sonys for the rear surrounds. I would love to get some more AL-III for the rears and center but even if I could drop that much coin I still would need to get amps. Anybody else here ever use the Crown K2 amp? I like rackmount equipment, as I change things around all the time, pushing cables onto equipment that doesn't move is much easier. I also like the newer Class D amps because of the efficiency. If I had 5 AL-IIIs I would need 2500W of amps or more, meaning I would have to install a dedicated 220V circuit just to power them! This can be avoided with the newer Class D amps like Crown K1-K2, Peavy DSC, etc.

Re: NY_EE AL-III + system.

Actually NY_EE, a 220V circuit is not going to do anything for you; what you need are a pair (or more) of dedicated 20A 120V circuits on the same side of the electrical panel. Also, going class D is not going to reduce your power requirements at full blast; AC power in requirements will still be sky high at high volumes even though they may be lower at low power levels. Carver and Sunfire amps are also very efficient at lower power levels due to their multiple stepped power supply rails especially when compared to conventional power supplies.

4500W of output power is still going to require a similar amount of AC power to generate.

Re: NY_EE AL-III + system.

Love the size of the room you have! How do you like the AL-III's? Did you have other speakers before to compare your thoughts?

One of my future projects will be to run dedicated 20 amp circuits......

Your close OBI , at 2500 watts divided by 120 volts is 20 amps ( simple ohms law ) , , so at 80 % of a 20 amp breaker ( 16 amps ) she will trip . Even at the panel you have 2 phases , the left hand side ( odd #,s.....) right hand side ( even #,s ) So left hand side is A phase ( 120 V ) and the right is b phase ( 120 V )....should you add breakers, always even the load at A and B phase . 4500 watts = 37/2=18 amps = 2 , 20 amp breakers , one on A phase and the other on B phase .

Re: NY_EE AL-III + system.

Steve thanks for the info, I didnt realize you had to balance each side of the panel, now that I think about it....it makes sense. Nice to have a electrician around!!

Steve, that is what I had done when I installed my 2 new dedicated circuit breakers for my system. What happenned was that I got persistent hum problems due to ground loops. My electrician solved the problem by re-wiring both circuits tot hew same side of the panel but he did balance things out by moving another circuit side to side (fridge I think).

Point is, you should always use a certified electrician to do things like this as he will know how to do th9ings properly and safely. Also helps to tell him how you plan to use the extra circuits so he can move things around.

I am a certified electrician in the state of Washington...... :-s ..And yes with out being there looking and testing your stuff , all I can do is give a little in site . But yes , use a qualified electrician . you didnt disclose why you would put booth breakers on one side , now that not always going to be the case either....but the bottom line A phase and B phase should have EVEN loads...

Re: NY_EE AL-III + system.

Regarding power, thanks for all the advice. When I mentioned a 220V circuit I was half joking. I have dreamed of a Furman AR-PRO for a long time but the cost is too high.

You have a great job NY_EE....I also have some Furman stuff , I like the one your looking at , especially the purple disconnect handle on the front.....That would be the ticket for you ( 2 of em )... :shock:

Does Furman make anything with a voltage regulator & power conditioner in one unit?
