Hi, all
We use an Sq7 for ower church and user approxamitly 42 channels. The sounds seems very well, but we have serieus faders issues. Some mechanical faders seems instable when they are connected to each other (two the same channels on two different faders). The fader gain was also jumping uncontrolled. (firmware 1.3.0) After two months the mixer is send back to the service point (promised one week repair time). But we get the mixer after 3.5 weeks, because service people was not availible. The instability in the faders was solved and the mixer was full tested, but we seems now a new issue with some faders. The mixer was again installed in a relative cold church (13degrees). From some mechanical faders the position was not corrosponding the internal fader gain (Check on routing display). The internal fader gain was +10dB and result in a large feedback, while the fader was at -inf. Moving the fader don’t change the internal fader gain. After warning up of ~1 hours the issue seems disapear and we couldn’t reproduce. (hardly to find the issue). We have move the processing channel to an other fader channel.
Is this temperature related? How big is the risk for live performance? Is this a mixer issue? Normally the mixer is warming up for an half hours and is the church warmed up to 20degrees. For now we take the risc for december (number of events). In the past we use digital mixers at low temperature for outside events. (yamaha 01v96!, digico, midas, soundcraft,…).
