[QUOTE="Karl Winkler, post: 33441, member: 255"] Re: Lectrosonics Quadra Digital IEM Review Good point - in fact, we think that the A/D converter we were using actually has a measured latency at about 2.75 ms. Guess what? That means that your results and ours are almost exactly matched. So, one thing we've figured out is that the re-sampling buffer introduces a group delay, and our initial investigation into this points to an amount of latency consistent with what we've found. The engineers are seeing if there is a way to shorten this delay by reducing the buffer size - they think they can do this. The result, interestingly, would probably be that the Quadra system would have about 1 ms of latency, whether it is fed from an analog OR digital source (right now, it has ~ 1.5 ms when fed digitally). Once we nail this down, we will revise our spec sheet. [/QUOTE]
