Bandwidth 20Hz to 22KHz +/- 1dB THD & Noise <0.8% S/N Ratio 94dB
Protection Integral, auto resetting, current limit & thermal protection. * The
AU4 is a class D switching amplifier so the RMS values are RMS equivalent, this is
that they give the same Sound Pressure Level using music or speech from a loudspeaker
as a linear amplifier delivering the quoted RMS level.
Power requirements AU4 12V DC @ 2.5A power supply provided
