Test Bench: Meridian G95 DVD Receiver
Meridian's G95 measured excellently in every test. Power was just about spot on its 100-watt spec, though the unit fell a bare 0.8 dB short of this level with all 5 channels driven. True to its high-efficiency Class D nature, the G95 remained at virtually the same temperature (warm, but not hot) whether it was left idling all day, or driven to the verge of clipping for long periods. Observant readers will note anomalous S/N results: better than theoretically perfect (-75.7 dB re: 1 watt) on our long-standing dithered-silence measurement. (Far better, on a Dolby Digital signal.) I have no immediate explanation for this, but I suspect it has to do with how the G95 oversamples and otherwise manipulates the incoming signal in the digital domain.
DOLBY DIGITAL PERFORMANCE
All data were obtained from various test DVDs using 16-bit dithered test signals, which set limits on measured distorting and noise performance. Reference input level is -20 dBFS, and reference output is 1 watt into 8 ohms. Volume setting for reference level was 85. All level trims at zero, except for 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: 105/154 W (20.2/21.9 dBW) 5 channels driven (8 ohms): 82 W (19.2 dBW) Distortion at 1 watt (THD+N, 1 kHz) 8/4 ohms: 0.02/0.03% Noise level (A-wtd): -88.6 dB* Excess noise (with sine tone) 16-bit (EN16): 0.8 dB Frequency response: 20 Hz to 20 kHz +0, -0.2 dB
MULTICHANNEL PERFORMANCE, ANALOG INPUT
No multichannel analog input
STEREO PERFORMANCE, DIGITAL INPUT
Reference level is -20 dBFS; all level trims at zero. Volume setting for reference level was 85.
Output at clipping (1 kHz, 8/4 ohms, both channels driven): 101/142 W (20/21.5 dBW) Distortion at reference level: 0.02% Linearity error (at -90 dBFS): 0.7 dB Noise level (A-wtd): -77.7 dB with 96-kHz/24-bit signals: -91.5 dB Excess noise (with/without sine tone) 16-bit (EN16): 0.6/1.2 dB quasi-20-bit (EN20): 8.0/7.5 dB Noise modulation: 0.3 dB Frequency response: <10 Hz to 20 kHz +0, -0.2 dB with 96-kHz/24-bit signals: <10 Hz to 44 kHz +0, -3 dB
Measured results obtained with Dolby Digital test signals. Subwoofer-output frequency response (crossover set to 80 Hz): 24 dB/octave above -6-dB rolloff point of 80 Hz High-pass-filter frequency response (crossover set to 80 Hz): 12 dB/octave below -3-dB rolloff point of 80 Hz Maximum unclipped subwoofer output (trim at 0): 3.6v Subwoofer distortion (from 6-channel, 30-Hz, 0-dBFS signal; subwoofer trim set to 0): 0.2% Crossover consistency: bass crossover frequency and slope were consistent for all sources and formats Signal-format consistency: consistent for all applicable formats Speaker size selection: all channels can be set to "small" Speaker-distance compensation: available for all main channels.
