Would you like to know for sure that your circuit performs up to its specifications? Ship it to me and I will measure it on my Audio Precision APx525. The AP covers the vast majority of audio measurements. For measurements outside the frequency range of the APx525, the HP 3563A and HP 3577A will be used.
Buyer is responsible for all shipping and customs brokerage costs associated with getting their circuits to and from Neurochrome’s location in Calgary, Canada.
