Hello, I received my Model 12 this morning, and I have no sound coming out of my headphones (guitar plugged in either directly with Inst enabled, or through the amp, in Live mode). Near the display, I have the red PFL/AFL light enabled, and no sound signal on the main VU. When I plug in my jack, the green Gain light doesn't light up. Have you ever encountered this problem? Thanks for your help :)
 
SIG light off = input signal level too low or no signal at all.
All input channels on the Model 12 have INST switch so you can verify if you have a defective channel or bad guitar cable.
Why is the PFL/AFL indicator on?
Your contribution to the discussion will be appreciated by the forum members.

Welcome to our community, @Th.B.

As @Max Relic has pointed out, it seems you have no signal coming into the mixer. So your signal chain into the Model 12 needs to be addressed before considering the Model 12's internal signal flow.

Once you resolve the incoming signal issue, if there's further concerns, we'll need to start with the basics.

In that case, since you're brand new to the Model 12, it would help if you first would confirm for us:
1. If you've followed the Owner's Manual (OM) steps in Section 5, "Basic Recording";
2. If you've looked over the OM Block Diagram's signal routing paths; and
3. If you've consulted the "No Sound is Output" segment found in the Owner Manual, Section 16, "Troubleshooting".

Having that information from you at the outset provides us with a way to go forward if you've already consulted/followed that guidence with no joy; and saves us the time of repeating what's already available in the OM, which us where we would otherwise need to start. ;)

So, the more information and interaction with the community, the better the likelihood we can help you get to making music.:)

Thank you for your answers. I take more time to understand (it's the first time with this kind of machine except a 4 tracks with K7 a long time ago). It's ok now. I
The problem is solved. The PPL/AFL light was activated because one of the unused tracks
had the solo button activated, which cut off the audio from the source. It's simple. But it took me 30 minutes to find it. So you really need to raise the Gain level, activate the track's Main button, and check that all the tracks are set to Main. Thank you for your time.

Thanks for posting your outcome (helps future users searching the forum about their problem/s).
Also a good reminder: these devices require the user to learn them thoroughly to use them effectively (and avoid simple problems)…like I often say: it ain’t like makin’ pudding!!!😁
 
Hello @Th.B, nice to hear you found a solution, you also had the chance to know it a little better. Now that you have your Model 12 set for the task, have fun making music.
