common ground amp

i4gotmyid

Is there a way to know if your amp is common ground just by looking at it? I have a H/K 440VKI in my small listening room powering my rt25i's. I know it is 40 watt/channel of high current power and was wondering if this would be better than my yamaha HT reciever for powering my SDA 2.3's, but I dont want to plug it in without knowing if it is of common ground or not. I emailed H/K but they havent returned my emails. I have the manual but it doesnt have any of that info.

Help anyone

Most manuals will not tell you because the issue is only with Polk SDA's. You may just want to try and cycle the power on and off very quickly a 40 watt amp does not contain huge power reservers to sustain the feedback signal. If you don't want to take any chances you can modify your cable using the guide from this thread.
