500 series electricity usage....

Just a quick question about the power suplies on 500 series racks... Does the rack drain more power the more modules are loaded into it. Ie.. would my electricity bill be greater with 10 modules than with 2? doesnt really matter cause im gonna be using them no matter what, but just curious.....

Also curious as to which is more efficient, a rack of 10 pres, comps or eq's in the 500 series, or a rack of 10 19inch comps pres or eq's all with a dedicated power supply.... Trying to be green here....

Yes the more modules the higher the current draw, and this totally depends on the module...some draw 4 times as much as others.
But even so the AC side will be very small, fulled loaded a 10 space would draw less than a 100 watt light bulb...or REAL close..
Your computer and monitor probably draws far more current, except for a laptop...

cool, thanks for the info. and in general, how do you think it compares to 19 inch rack gear?

Preamps and eq's are excellent. Compressors seem to get mixed reviews.

thanks, but i was actually referring to how much power the units draw...

Mike question?
units not being used would be at idea would not?
if so, isn't the current draw very much reduced ( excluding bulbs )?
P.S. hope all is well in your neck of the forest: )~

Yep for sure, have about the lights burning in the studio?, a 500 box would not even cross my mind for burning power....
He should check his hot water heater, Frig or heat pump first.

I put a meter on a 6 slot, 17 watts powered up

hey, the lunchbox plugs into a wall right? in my mind that makes it fair game for using what we call electricity..... And, i can only assume that since the entire 10 units draw less than a lightbuld, that they would be more efficient than 19 inch rack gear?

Yes, but a 10 space should draw no more than 25 watts sitting there.

Question not clear.
Units Not used; do you mean modules or slots open?

modules just setting idle in the rack or lunchbox.
as in using one pre but the other units are powered on but not being used.

Draw about the same current; except LED display ect...
A signal thru module or not, if powered up.. it's drawing current.
Even class AB circuit changes very little with and without audio, if it did change it would be very small..
For example: an API 2520 draws about 12 to 15 mills, regardless of audio..
The extreme would be if it was driven VERY hard into a low imp. load, less than 600 ohms.
Then Ohms law takes over..
Another example; the 990 draws around 25 mills, until the load excedes that 25 mill idle current...
