Power Amplifier VU Meter with Driver Board Kit Sound Audio Level Indicator Audio Level Meter with Backlit for DIY Home Car White 960uA Maximum Current Sensitivity

I use a class-D power amp which has continuous 400kHz 300mv carrier. I've tried other stereo power meters where either the amp carrier biased the meter up to 0.1 watt, had too narrow a useful power range, or both. My listening is typically less than 1 watt, so I was able to calibrate this meter to 1 watt at the 0dB reading. Full scale, +6 db, corresponds to 8 watts. The response is faster than other meters I've used so it seems useful for capturing peaks. And thankfully it ignores the amp carrier so it reads zero with no signal. One thing tripped me - the signal input for VU1 is the yellow lead, not the read one on the same side as the VU1 jacks.
