Krell KSA-200s First Time Use

@ BRf, Hi, Read the ops post above again, He tried to use the krell ksa with a standard lighting wireing, right now, the breaker 15 amp or 20 amp has nothing to do with it, The op needs to run a dedicated 10 awg electrical wire in attic from breaker to receptical being used with a hospital grade 20 amp receeptical, then he can install a 15 amp breaker or a 20 amp breaker, I really believe he needs a 15 amp breaker, LOL!, My amp is a krell 700cx running on 6 ohms speakers with a 20 amp breaker!, thats 1,050 watts a channel!, If a 20 amp breaker can run that, why in the world would he need a 20 amp breaker for such a low powered krell amp?, However, I am going to do a 30 amp breaker, just to run smoother and result with a few percent better sound, keep in mind thou, the my amp runs very good with the breaker I have,the op needs the 15 amp breaker to better protect his investment, a 20 amp breaker takes more to flip when something goes wrong, he does not have the power as I do, cheers.

Audiolabyrinth, the Krell KSA-200S manual states that the amp is designed to be used with a dedicated 20amp circuit. However, I believe that the OP’s problem is not attributed to him using a 15amp circuit due to the fact that the amp cannot even turn on at idle, plus the existing 15amp circuit does not trip. A 20amp supply is required for the amp to operate “optimally” under a difficult load requirement.

A 10g dedicated line with a hospital grade receptacle etc etc may improve on the sound, but is not the source of the OP’s problem.

Prof. John, just a wild arsed speculation here, but is it possible the amp is tripping because it needs to be hooked up to the speakers. Maybe the open circuit is doing it. If not, it's time to call the factory.

@ Brf, Hi, If the op does not have problems with the krell amp its self, I assure you that I am correct, there is no way a krell amp is going to work without a dedicated line!, The amp draws to much current!, LOL!, I tried that once with a krell fpb 200, you should have seen the bulbs in the house flicker and some blew, and guess what, the amp would shut off to stand by quickly!, how do you know the op has a 15 amp breaker now?, If he does, LOL!, thats a 15 amp breaker for a room or two rooms in the house, not a single receptical that his amp is plugged into!, regardless, I hope we can help the op here,I have 18 years of exsperience with krell amps!, The ONLY krell amp that I could ever run on standard house wireing receptical was a krell 300I intergrated amp, everything else had to have a dedicated line with a 20 amp breaker to work!, the op can use a 20 amp breaker for his krell ksa 200s and still work, His problem is he cannot share power to the amp with anything else!, cheers.

Audiolabyrinth, the 20amp supply is required when the amp is required to provide large amounts of current under load. The OP's problem is that he cannot even get the 200S to stay on at IDLE.

My former KSA 250 would operate with a 15amp circuit, although peak performance was obtained with use of a 20amp circuit.

If the OP amp was trying to draw too much current from the 15amp circuit, why does the 15amp circuit trip?

The best advice is to give Krell a call or try the amp with a dedicated 20amp circuit to satisfy Audiolabyrinth's concern.
