Thank you for the response Dakos. However, I am not understanding the formula used here:
The XTI takes dBfs units and not dB or dBu, dBfs units are relative to the amps max power, the maximum power output of the XTI is 650W, that equals 0 dBfs. Your speakers are continuous (RMS) 250W (pgm 500W, peak 1000W), from here it's just a plain dB ratio formula, you get:
10 X Log(P1/P2)=10XLog(250/650)= -4.15 dBfs.
The last part doesn't make sense to me even using the OP amp ratings. I tried the math but cannot get the same result. I need gentle guidance !!!
