<p>Fired them up tonight to find everything works really well. Once the packs were fully energized, one began triggering an internal relay switch that sounded as if something was toggling back and forth about 2x per second. It didn't appear to cause any issues, but at one point the strobes spontaneously fired one time, but the tranceivers are also new to me, so they could have been the culprit in that case.<br>
Any ideas what what switching sound would be? I imagine it will be distracting for someone if they were in the studio with them. Thanks again for your help!<br>
