LED light causing hum/interference, but only from SE-02

<!-- SC_OFF --><div class="md"><p>I've noticed that when I have my LED desk lamp turned on, there's interference when I try to record my SE-02 synth. However none of my other synths (DM12, Rev2, XD and UNO) have this problem, they produce a clean signal even with the LED light turned on. The noise is a &quot;screeching&quot; electronic type of sound, as well as a lower hum mixed in.</p> <p>Since the noise goes away when I turn off the desk light, my feeling is that the core issue is the desk light itself or its PSU. It has a very cheap feeling PSU that gets rather hot. I have disconnected the light for now, and I will look for a higher quality AC/DC adapter for it (it's a nice lamp).</p> <p>But could this also indicate a problem with the SE-02? Why is it affected by the desk light, but none of the other synths are?</p> </div><!-- SC_ON --> submitted by <a href="https://www.reddit.com/user/AdvancedFollower"> /u/AdvancedFollower </a> <br/> <span><a href="https://www.reddit.com/r/synthesizers/comments/qaw241/led_light_causing_huminterference_but_only_from/">[link]</a></span> <span><a href="https://www.reddit.com/r/synthesizers/comments/qaw241/led_light_causing_huminterference_but_only_from/">[comments]</a></span>
