Arcam AV8 Pre/Pro HT Labs Measures

HT Labs Measures: Arcam AV8 Pre/Pro

The above chart shows the frequency response of the left (aqua), center (green), LFE (red), and left surround (blue) channels at the preamp outputs of the Dolby Digital decoder. The left channel measures -0.00 decibels at 20 hertz and -0.33 dB at 20 kilohertz. The center channel measures -0.00 dB at 20 Hz and -0.31 dB at 20 kHz, and the left surround channel measures -0.00 dB at 20 Hz and -0.34 dB at 20 kHz. The LFE channel, normalized to the level at 40 Hz, is -0.00 dB at 20 Hz, reaches the upper -3dB point at 111 Hz, and reaches the upper -6dB point at 118 Hz.

The analog frequency response measures -0.00 dB at 20 Hz and -0.04 dB at 20 kHz. Looking at a broader bandwidth, the response measures -0.03 dB at 10 Hz and -0.28 dB at 50 kHz in direct mode. In modes that involve signal processing, the response is -0.12 dB at 10 Hz, -0.03 dB at 20 Hz, -0.35 dB at 20 kHz, and -58.51 dB at 50 kHz. The analog THD+N is less than 0.055% at 1 kHz with a 100-millivolt input and the volume control set to +56. Crosstalk with a 100-mV input was -95.63 dB left to right and -96.37 dB right to left. The signal-to-noise ratio with a 100-mV input from 10 Hz to 24 kHz with "A" weighting was -95.65 dBrA.—AJ
