per attachment circled in red with the box turned off, it appears this box is generating a 20Khz sinewave tone on the analog line outputs whether the box is on or off, this tone is generated, i have not tested this on other outputs.
i believe this is inherent to all SA boxes, so my question is, anyone else (with capabilities) seeing this ?
its not an issue for me since im using a LPF cutoff at 16Khz anyway but i was just curious that if this is indeed inherent, what is the purpose ?
a copy protection scheme of some sort ?
