PN4.520D FINALLY installed
#11
bike running!!!!!!!! - see "my" sticky with bench test results and UN's sticky regarding DDM dial in.
On the latter.... READ the DDM stickey BACKWARDS. UN started the thread with the explanation on how to calculate the Vac value and it is incorrect.
only use 1 channel value (so for 2 ohm speaker on the 4.520 that would be 130W)
if you read the complete thread, you will see me and UN (A GOOD friend of mine) go back and forth on 130 or 260W (for your example) used for calculating the VaC.
After I did the initial batch of amp tests and UN did some as well (with WAY better equipment), he "confessed" I was right (O scopes simply do not lie LOL).

P=130
R=2 ohms
V=130 x 2.0 = 260 square root = 16.12 VAC
If I use the 2.7 ohm (which is what I did) I get 18.73VAC, mine are set at the limit that UN had in the first part of the sticky so the gains are really high right now.
