Not sure why you are asking for the amps the 770 can produce. Do you need to know for each channel driven seperately or all seven driven simultaneously? I had a H/K that stated it could supply +/- 35 amps instantaneously. So what! Why is this a concern for your purchase? If current demand is of a great concern, I would suggest mono blocks with dedicated ac circuits for each amp. Othewise, the 770 is definately a powerful amp that has always met my needs, (and I drive 6 outside speakers 100 feet away from the amp during the summer).
