Hi guys, i found a bug in 1.4.4. when changing scenes. [![](https://us1.discourse-cdn.com/flex002/uploads/allenheathdigitalcommunity/original/2X/8/8adfc3b36848a3bfb71b3b0ef2b872e4544c4abc.jpeg "I found a Bug! SQ Firmware 1.4.4.") ](https://www.youtube.com/watch?v=tF91BGRutQ8) When changing a from a scene where on a channel 48V is off to a scene where 48V on that same channel is on, the gain is peaking shortly a cause a short feedback. Cheers, Andre´ ---

if you switch the phantom power on it always peaks a moment ---

@SteffenR ??? Our phantom power is always on for any mike that needs it. How would changing scenes turn phantom power off or on? @Andre S Sounds like the scenes all need phantom on initially to avoid the problem. ---

@SteffenR Ours does not do that. Why doesn’t having the phantom power on for each scene not turn it on or off when you change scenes? I can see problems if the phantom power was off in some scenes and on in others. ---

I saw the same experience, and also thought it was related to version 1.4.4. However I realized that the scene which had more than 48V, did not have the good gain either. However I remembered that modifications were made on these scene, but WITHOUT STAGEBOX connected. And there indeed the scene is memorized WITHOUT 48V and a gain not in conformity. And so it will not be restored when we reconnect the STAGEBOX. ---

if no stagebox is connected how should the system know the right gain? ---

Sure, but we could have imagined that the gain and the 48V command be memorized in the scene, stagebox connected or not. ---

Hi @PBo67, Preamp control (48V, PAD and Gain) are remote controls for the analogue preamp (pre-AD-conversion). These are not a part of channel processing, and belong to each socket, rather than each channel. Therefore, you would need to have the expander connected to set these - you couldn’t for example switch an input source to local, set the gain and then switch the source to an expander and have the same gain. A scene **will** store all preamp settings, but again, the setting is socket based. In fact, there are up to 33+128+128=289 preamp settings for an SQ-7! Thanks, Keith. ---

Hi Keith, I don’t really understand this story of an expender ! moreover, unfortunately, there is NO expander on the SQ. On other consoles, analog gain is one of the parameters memorized in the scene WITHOUT stagebox connected.
