We do NOT hold the line voltage constant like some publications do, as we believe in testing for real world conditions. Consumers typically don't have the luxury of stabilizing their power and/or providing enough wall current to source max power with all channels driven (a very unrealistic test condition and a very idealistic test load we might add). In any event, I was able to achieve a 170wpc at 0.1% THD with four channels driven but noted that my dedicated 20A line sagged from 124V to 119V under this test. In reality, the AVR-5805 probably could have delivered an extra 10wpc or so in a more sterile lab environment. This test certainly proved the AVR-5805 was a true powerhouse. For the fun of it I reran this test for five channels driven and was able to achieve about 145wpc at 0.1% distortion but again watched the line voltage sag down to 110V during this test...
.....For a 120VAC system your line would be required to deliver 25 amps! Unless you are running 3 phase power, or convince the power company to run 6AWG romex and up the circuit breaker from a standard 15A to a hulking 25A, this simply isn't gonna happen
Esto esta extraido e de las especificaciones quedan en la review:
# Multiple high voltage (80V) capacitors (4 x 33,000uF = 132,000uF, or 66,000uF per rail). In order to do 170wpc, a minimum recommended cap voltage of sqrt(2)*34.64 + 5 = 57V should be used. Using 80V gives them plenty of design margin and added headroom since the rails can swing much higher.
# A massive torodial transformer (borrowed from the AVR-5803) and dual E-core transformers (borrowed from the AVR-2805) ensures this amp can utilize the full rated power from the wall outlet (120V,15A) if called upon.
