Crown PS-200

[kartsmart]

I am using a ps400 for upper bass and PS-200 for my horns . the ps-200 when the volume controls are set, channel 2 output is lower than channel 1 , it seems that I have to set it 5 marks higher than channel 1 to get it to balance . did cable swaps etc , the indicator lights agree I am sure it seems to be in the amp.
Is this a problem ? what can I do ?

The Crowns have input attenuators, not volume controls. Turn them both all the way up and see if they're balanced.

Assuming you've swapped cables on both input an output to test the pre-crossover output as well as the horns themselves?

yes I have the peak limiters lights tells me that the balance is not right also , swapped horn drivers cables , the input attenuators set the same it does not balance out , but when I set the balance so the limiter lights are near equal the balance seems equal

Try flicking the stereo/mono switch back and forth a few times, just be sure to get it back into stereo.

forgot about that switch ---- will check it out ------ thanks

I picked up some direct replacements from Rat Shack if you have one nearby and want to just replace it, #275-0407

No music is recorded ..equal SPL... per channel (unless mono)

Okay . . . but if you're checking to see if your system is putting out equally on both channels, it's easy to run a mono signal. Then setting the Crown input attenuators at max would take that variable out of the test.

If you look on line there is a list of Crown service centers. May be one near you. When I got my PSA-2 a few years ago, I called the local service center and they were still doing business. Couldn't be sure he'd have the parts on hand, depending what was found, but still doing repair work on Crowns. (I never did take it in as it works fine as far as I can tell.)
Give that a try. Could be a local shop that you can just drive your equipment over to.
These amps have a rock solid rep. It's been told that Crown would run a 60 cycle tone in with enough gain to produce 120 volts on the output, plug in a washing machine and do a load of towels, then hook it back up to speakers and play music!
The other story you'll hear from people that used Hammond organs is they would do the same thing to get the organ to sound right. If the 60 cycles were off then every note on the organ would be off, so using the Crown as sort of a power supply/filter was a great work around.
