malcevansmusic Posted March 29, 2014 Share Posted March 29, 2014 Hi. Just wondering if anyone has had this issue before? I had to use phantom power on channels 1-6 and 7-12 last night for the first time. Unfortunately 7-12 didn't work, despite the desk indicating the power was on. Is this a known issue, or something I'll have to have looked at by Line 6? 99% of the time this won't be an issue for me, but it was annoying to have to swap microphones late in our soundcheck to get around the issue. Thanks. Malc Quote Link to comment Share on other sites More sharing options...
silverhead Posted March 29, 2014 Share Posted March 29, 2014 Make sure you are running the latest firmware. I recall an issue involving phantom power that was resolved in a firmware update. I can't recall whether it was exactly this issue, but it's worth checking. 1 Quote Link to comment Share on other sites More sharing options...

tinorios Posted March 30, 2014 Share Posted March 30, 2014 Make sure you are running the latest firmware. I recall an issue involving phantom power that was resolved in a firmware update. I can't recall whether it was exactly this issue, but it's worth checking. It was update from version 1.0 to version 1.1, Silverhead. See the paste below from Firmare 1.1 Update information in the Knowledge Base: Status of the phantom power of channel 7- 12 was not saved with setups on previous firmware version. The problem Malce is having needs to be investigated by Line6 to determine if it is systemic (all M20d's have the same problem), or something unique to Malevans mixer. I only have one condenser mic so I can't try it out. 1 Quote Link to comment Share on other sites More sharing options...
malcevansmusic Posted March 31, 2014 Author Share Posted March 31, 2014 "I only have one condenser mic so I can't try it out." One is all you need! I've tried one condenser mic in 1-6 and it works. I've tried it in 7-12 and it doesn't. The desk is saying Phantom power is on, but no power is getting through. It's not the issue: Status of the phantom power of channel 7- 12 was not saved with setups on previous firmware version. Quote Link to comment Share on other sites More sharing options...
bassman24 Posted March 31, 2014 Share Posted March 31, 2014 Stupid question and not meant offending: Have turned phantom power for channels 7-12 also? Phantom Power has to be turned on seperately for rows 1-6 and 7-12. Nevertheless I have just tried my cajo mic on both rows and both are working just fine. If one row is not working even if phantom power is turned on for that row you should turn it in for repair. Quote Link to comment Share on other sites More sharing options...
malcevansmusic Posted March 31, 2014 Author Share Posted March 31, 2014 Unfortunately 7-12 didn't work, despite the desk indicating the power was on. Yes, power was on. Just checking to see if anyone knows of any known software glitches... Quote Link to comment Share on other sites More sharing options...

It's not the issue: Status of the phantom power of channel 7- 12 was not saved with setups on previous firmware version. Hey Malce, I tried it with my one Shure SM94. I put it in Channel 1 & tried different combinations of 48V on & off. Then, I repeated it channel 12. Your post seemed to lead to the problem being with both banks on with condenser mics connected to both banks. I couldn't duplicate your situation because of my one mic. Below is a table of what I found. Bank1-6 Bank7-12 Mic Output 48V 48V Location Sound OFF OFF B1-6 NO ON OFF B1-6 YES OFF ON B1-6 NO ON ON B1-6 YES OFF OFF B7-12 NO ON OFF B7-12 NO OFF ON B7-12 YES ON ON B7-12 YES ​With both banks on, the mic still worked while connected to channel 12. So both banks of my mixer are working with only one mic. That's as far as I can go. Hope this helps you. At least the problem isn't with all the M20d's. By the way, making a table in here was hard. It reminded me of doing one in a typewriter. You guys do remember typewriters, right? Quote Link to comment Share on other sites More sharing options...
eukieb42 Posted April 5, 2014 Share Posted April 5, 2014 I had the same problem on Bank 7 to 12, Phantom power showing but microphone not seeing it. This, coupled with a few other problems before the updated firmware resulted in me having to send the mixer back to Line 6 who replaced it without hesitation once they received my mixer.

PatFoghorn Posted April 18, 2014 Share Posted April 18, 2014 I am having a similar issue. I tried a couple of condenser mics on random inputs in banks 1-6 and 7-12. Plugged in the mic, turned on phantom power, no signal. I haven't tested every input, but that's my next step. I will also test the cables and mics on another board just to be certain I'm not being silly and using broken equipment. Any other suggestions? I updated the firmware last night and it did not alleviate my problem. Quote Link to comment Share on other sites More sharing options...
PatFoghorn Posted April 22, 2014 Share Posted April 22, 2014 Tested all of my mics and cables to confirm that they are in fact in working. Updated the firmware in the StageScape to the most recent version. Still no phantom power. Any other suggestions other than sending it to be serviced?

scotterp Posted April 22, 2014 Share Posted April 22, 2014 Best to contact customer support and get a ticket for this one. They'll let you know how best to proceed from here. Quote Link to comment Share on other sites More sharing options...
CrashAve24958 Posted July 28, 2014 Share Posted July 28, 2014 I too have the same issue with my soundscape, only with my unit it is bank 1 to 6 that do not respond to phantom power. I have noticed it the last few gigs and got by by moving all condensers to 7 - 12. Quote Link to comment Share on other sites More sharing options...
mapletop Posted December 30, 2018 Share Posted December 30, 2018 hi,how do i know my phantom power is turned off how do you get to it.im new sorry Quote Link to comment Share on other sites More sharing options...
Rewolf48 Posted December 31, 2018 Share Posted December 31, 2018 You know if phantom power is actually on or off if a powered device attached works or not. Such as a condenser mic or powered DI box. Control from the M20d is on the Setup screen when you press the I/O bar there are two 48v buttons on the left which toggle it on or off for the upper or lower bank of inputs. See page 18 of the Advanced manual: https://line6.com/data/6/0a06434c12bb52431be9dd7c2/application/pdf/StageScape M20d Advanced Guide - English ( Rev D ).pdf Quote Link to comment Share on other sites More sharing options...
