TEST BENCH
DOLBY DIGITAL PERFORMANCE
All data were obtained from various test DVDs using 16-bit dithered test signals, which set limits on measured distortion and noise performance. Reference input level is -20 dBFS, and reference output is 1 watt into 8 ohms. Volume setting for reference level was -4. All level trims at zero; except for during subwoofer-related tests, all speakers were set to "large," subwoofer on. All are worst-case figures where applicable.
Output at clipping (1 kHz into 8/4 ohms)
1 channel driven: 174/218 W (22.4/23.4 dBW)
5 channels driven (8 ohms): 148 W (21.7 dBW)
7 channels driven (8 ohms): 121 W (20.8 dBW)
Distortion at 1 watt (THD+N, 1 kHz)
8/4 ohms: 0.05/0.06%
Noise level (A-wtd): -75.0 dB
Excess noise (with sine tone)
16-bit (EN16): 0.7 dB
Frequency response: 20 Hz to 20 kHz +0, -1.4 dB
MULTICHANNEL PERFORMANCE, ANALOG INPUT
Reference input and output level is 200 mV; volume setting for reference output level was -4.
Distortion (THD+N, 1 kHz, 8 ohms): 0.04%
Noise level (A-wtd.): -84.1
Frequency response: <10 Hz to 115 kHz +0, -3 dB
