Don't know if its the right place to post my question, but I'm sure there are guys here that can help.
I found few l-pad stereo attenuators but all i know about them that their wattage for single channel is 15w. Now i want to build an amp attenuator for my amp and i have 2 questions:
1. How can i measure/know what the impedance of the l-pad? As far as i know if it won't match the impedance of the amp and the cab it will damage them both.
2. Can i wire in series the two channels to get a mono channel with higher power rating?
Thanks in advance
