Re: Crown K2 frequency response vs other amps

I have to agree with Behringer customer service, its like there is no one there if your trying to contact them. I think the company is just that big they probably ignore anything minor, which is horrible to have to deal with for sure.

Ive not had any issues with anything breaking though, and Ive used and known other people use quite a few Europower amps. That said, I never used the power switch on the amp itself, I always turned it on and off at the wall.

Re: Crown K2 frequency response vs other amps

I can confirm those measurements as the ones I had taken were the same. Be careful of measuring the K2 as there is the standby feature which kicks in after 6 seconds or so. If it is in standby when you take the measurements it does look quite weird.

I made this ~a year ago, it is a calibrated sweep of a crown k2 amplifier; If memory serves me correctly, there is a high pass filter at 8hz and a lowpass at 32khz (it is in the k2 documentation on their website)...
it is ~1.7 db down at 8 hz, so it will definitely work well at 10

it is 10 db down at 4.88 hz

Edit/addition:
lab gruppens go to 1.5 hz (their filter is at 1.5 hz)

Re: Crown K2 frequency response vs other amps

There is a way to either disable the standby feature (there is a jumper on the input board [inside the amp]) which can be triggered that will keep it from shutting off at all, you can also change a resistor (z1 i believe) to 1 megaohm which will make the timout ~1 min as opposed to 6 sec.
