Sonance DAB1 Distributed Audio System HT Labs Measures

HT Labs Measures: Sonance DAB1Distributed Audio System


Two channels of one zone driven continuously into 8-ohm loads:
0.1% distortion at 50.9 watts
1% distortion at 56.3 watts

Analog frequency response:
–3.97 dB at 10 Hz
–1.37 dB at 20 Hz
–0.26 dB at 20 kHz
–1.41 dB at 50 kHz

This graph shows that the DAB1's left channel, from Source 2 input to speaker output of Zone 1 with two channels driving 8-ohm loads, reaches 0.1% distortion at 50.9 watts and 1% distortion at 56.3 watts. Into 4 ohms, the amplifier reaches 0.1% distortion at 61.9 watts and 1% distortion at 69.7 watts. Crosstalk at 1 kHz driving 2.83 volts into an 8-ohm load was –78.11 decibels left to right and –83.23 dB right to left. The signal-to-noise ratio with 2.83 volts driving an 8-ohm load from 10 Hz to 24 kHz with "A" weighting was –95.03 dBrA.—MJP
