s16 Erratic phantom power channel behaviour
Hello! I am stuck with a problem,
I have been using my s16 stagebox for some time with no issues, but recently I have experienced issues with enabling and disabling the 9-16 channel bank phantom power. It is a consistent problem/fault and I am hoping someone might be able to tell me if I have a faulty stagebox... and what to do about it.
From COLD, unconnected (no connection to console) state, the unit powers on perfectly, but channel 15 shows enables phantom power, even though it is set to OFF on the unit, and the 48v button is not lit. The LED remains on and the phantom power is present on the input...
After using the 48v power button to switch it on, the button lights up as usual, but then channel 9-15 phantom power LEDs all light up, and nothing can be done to switch them off again. Powering the unit off and on again and the LEDs don't go out, on power up, the phantom LEDs on channels 9-15 all come on.
If I leave the unit for an hour or so, and power up again, only the channel 15 phantom LED comes on, and I'm back to square one.
The audio on all 16 channels work fine, and channels 1-8 behave normally, and work normally too.
There has been no physical impact to the unit, and it has only had very light use as per my photos. Only been gigged a handful of times, and stored in ambient dry temperatures from new. Oh, and flightcased from new.
Do I need to return the unit for repair? If so - how?
Thank you for your help
