This graph shows that the LX-7's left amplifier channel, with two channels driving 8-ohm loads, reaches 0.1% distortion at 293.2 watts and 1% distortion at 322.5 watts. Into 4 ohms, the amplifier reaches 0.1% distortion at 245.3 watts and 1% distortion at 286.8 watts. An input level of 102.4 millivolts was required to produce an output of 2.83 volts into an 8-ohm load, indicating an overall gain of 28.83 decibels using the RCA input. When using the XLR input, a level of 205.0 mV was required to produce an output of 2.83 volts into an 8-ohm load, indicating an overall gain of 22.80 dB. With six channels driven into 8-ohm loads, the amp reaches 0.1% distortion at 199.5 watts and 1% distortion at 228.6 watts.
sound and vision 當初對5008的測試在五聲道跟七聲道幾乎跟609差不多!?
有人覺得是網站弄錯數據了
Onkyo TX-NR5008 A/V Receiver HT Labs Measures
HT Labs Measures
Five channels driven continuously into 8-ohm loads:
0.1% distortion at 79.1 watts
1% distortion at 95.5 watts
Seven channels driven continuously into 8-ohm loads:
0.1% distortion at 78.7 watts
1% distortion at 94.6 watts
5008的測試在兩聲道就正常許多 ,理論上多聲道不可能差到這樣
論上
This graph shows that the TX-NR5008’s left channel, from CD input to speaker output with two channels driving 8-ohm loads, reaches 0.1 percent distortion at 162.8 watts and 1 percent distortion at 194.1 watts. Into 4 ohms, the amplifier reaches 0.1 percent distortion at 248.1 watts and 1 percent distortion at 309.5 watts.

This graph shows that the 7500’s left channel, with two channels driving 8-ohm loads continuously at 1 kHz, reached 0.1% distortion at 284.9 watts and 1% distortion at 342.3 watts. Into 4 ohms, the amplifier reached 0.1% distortion at 447.6 watts and 1% distortion at 492.8 watts.
With five channels driven continuously into 8-ohm loads, the AVR reached 0.1% distortion at 260.1 watts and 1% distortion at 301.1 watts. The manufacturer’s stated distortion of 0.03% was reached at 238.7 watts, which is actually higher than the spec'd 200Wpc at that distortion level with all channels driven.
