Harman Kardon BDS 5 Blu-ray Receiver HT Labs Measures

HT Labs Measures

Five channels driven continuously into 8-ohm loads:
0.2% distortion at 49.8 watts
1% distortion at 54.8 watts

Analog frequency response in Stereo mode:
–0.88 dB at 10 Hz
–0.25 dB at 20 Hz
+0.34 dB at 20 kHz
–27.50 dB at 50 kHz

This graph shows that the BDS 5’s left channel, from Aux1 input to speaker output with two channels driving 8-ohm loads, reaches 0.2 percent distortion at 52.4 watts and 1 percent distortion at 55.4 watts. Into 4 ohms, the amplifier reaches 0.2 percent distortion at 67.4 watts and 1 percent distortion at 90.9 watts.

There is no multichannel analog input to measure. THD+N from the Aux1 input to the speaker output was less than 0.055 percent at 1 kilohertz when driving 2.83 volts into an 8-ohm load. Crosstalk at 1 kHz driving 2.83 volts into an 8-ohm load was –88.19 decibels left to right and –90.46 dB right to left. The signal-to-noise ratio with an 8-ohm load from 10 hertz to 24 kHz with “A” weighting was –93.49 dBrA.—MJP
