Boat Anchor Audio is offering two new products for your consideration.
Our first product is a variable (30cps to 20kcs) audio bandpass filter that will reduce the total harmonic distortion (THD) of a low cost audio generator to allow some serious audio troubleshooting and testing.
Also, our filter may be used to reduce the THD in lab quality audio function generators to as low as 0.0020%. More info here.
We are also happy to announce our new Virtual Ground (rail splitter) to provide positive and negative rails along with a ground from a 2-wire power supply. More info here
