Nut, yes all receivers do put out their rated power; this is governed by FTC regulations, and failure to do so would be a violation of the law.
If this is so how do manufactures get away with things like this.
Onkyos published specs for the 807.
135 W + 135 W (8 ohms, 20 Hz–20 kHz,
0.08%, 2 channels driven, FTC)
Center 135 W (8 ohms, 20 Hz–20 kHz, 0.08%,
2 channels driven, FTC)
Surround L/R 135 W + 135 W (8 ohms, 20 Hz–20 kHz,
0.08%, 2 channels driven, FTC)
Surround Back L/R 135 W + 135 W (8 ohms, 20 Hz–20 kHz,
0.08%, 2 channels driven, FTC)
Dynamic Power 300 W (3 ohms, 1 ch)
250 W (4 ohms, 1 ch)
150 W (8 ohms, 1 ch)
THD (Total Harmonic Distortion) 0.08% (Rated power)
Then it tested like this.
Onkyo TX-NR807 A/V Receiver:
HT Labs Measures
Five channels driven continuously into 8-ohm loads:
0.1% distortion at 105.5 watts
1% distortion at 122.0 watts
Seven channels driven continuously into 8-ohm loads:
0.1% distortion at 29.9 watts
1% distortion at 33.0 watts This isn't a bit misleading? Is it all in the wording from the manufacture? In each case Onkyo rated the specs with 2 channels driven.
One would be thinking they would be getting a true 135 watt (all channels driven) receiver but in reality they wouldn't unless it was with only 2 channels driven.
