Q: At reset a loud knock appears at the speaker - how to avoid this ?

lmorelli Theknock (or "bump" ) is due to the power off-power on of the system. To avoid it you should isolate the amplifier from the power source.

lmorelli The kit generates waveforms with a defined amplitude. You have to match the correct amplitude, frequency, waveform and impedance of your own transductor. The kit should easily reach 100 kHz, but the waveform tends to degrade above that frequency.
