<!-- SC_OFF --><div class="md"><p>I bought a 4ms Listen 4Q and the main outs work without any noise, but the 3.5 mm headphone out has a low, but distinctive electrical noise. It's mostly overtaken when in use, but is still noticeable. It isn't affected by any of the gain controls on the module, either.</p> <p>I do have several digital modules (Intellijel Metropolis, Instruo Arbhar, Disting MK4, and Qu-Bit Scanned) on the same bus board and noticed a significant reduction in noise when unplugging some of them. Moving neither the module itself nor its power connector's location on the bus board made a difference.</p> <p>What are my options for removing (or at least reducing) this noise? Why wouldn't the main outputs have the same issue?</p> </div><!-- SC_ON --> submitted by <a href="https://www.reddit.com/user/ethandrzb"> /u/ethandrzb </a> <br/> <span><a href="https://www.reddit.com/r/modular/comments/kw1mo9/electrical_noise_on_4ms_listen_4q_headphone_out/">[link]</a></span> <span><a href="https://www.reddit.com/r/modular/comments/kw1mo9/electrical_noise_on_4ms_listen_4q_headphone_out/">[comments]</a></span>
