I thought when a Reciever was rated for 90Wx7 that they indeed, had 7 small amlifiers each rated to 90W. No?
Correct but the Power Supply in the avr most likely is not capable of supplying that much to all 7 amps at the same time so the amps are limited by the cheaper power supply.
So... does that mean that they cap the per channel output to 90W continuous, or if I only hooked up 2 speakers could I run theoretically get 315W per channel?
only on some models can you get that much power when the other channels are not used. most avr's when in 2 channel mode will have good enough amp sections on the mains to achieve higher than 7 channel specified ratings but to achieve a near halving of the total power is something usually only found in seperate amplifiers like Axioms A1400-8.
