Omrat,
Those banana plugs are so old school! That is one of the reasons I step upped to the Matrix.
TMO this can not be the reason that the amp goes in protective mode.
Take your ohmage meter and do some measerements.
Stick your mono jacks in both your connectons of the cabinet and measure the tip and sleeve on the banana end.
This should be the same! If not there is a problem well then it are the cables/jack plugs or the cab connections or the cab wiring.
If is reads the same value. Then the ART has a problem.
Square contacts are ok on both jacks. When I insert plug, all three square jacks are reacting.
Allso this "bad connector" seems ok to me.
I can control the volume level only via channel one.
Are you 100% sure that you've switched the amp from mono bridged mode to stereo mode?
That switch can't be toggled with your fingers because it's recessed so much.
You'll need to use a pencil tip or a small screw driver to toggle it.
Omrat,

Yes, that's correct. That's what was causing the amp to go into protect mode: both outputs were being shorted together.Ok, just realized that I had banana plugs connected to ART SLA 2 wrong
Like I said, I'm total rookie.....
This is the right way right (red to red and black to black ) ?
Can you help me understand what you're saying here? It's unclear whether you can hear bpth speakers, or can only control volume on one speaker.BUT - only one speaker is working ( right or left - I tryed to switch banana blugs between channel 1 and 2 )
AND - I can control the volume level only via channel one.

Good. One less thing to worry about.
+1. That's why I only use banana plugs when there is no other choice. Too easy to make a mistake.Those banana plugs are so old school! That is one of the reasons I step upped to the Matrix.
This is exactly the reason. With the banana plugs reversed, the cabinet wiring was shorting the + side of each channel together. The - side is already shorted by the SLA itself. The net result is that both channels were shorted together. When channel 1 went into protect mode, it removed that channel, and left channel 2 free to drive the speaker.TMO this can not be the reason that the amp goes in protective mode.
That would be a better way to do it. But the way it's wired now, it should give satisfactory results when the cab is connected to two channels of the the same amp.I still am wondering about the connection on the left, I think the blue wire should be on the right side of that connector.
Well maybe... [way I see it from the pic] the blue appears to be the "return" (non-hot) circuit, and would need the connection the way it is for the mono jack to work. If the blue wire was on the other side of the connection on the left, you'd need to [partially] insert a jack to complete the circuit.That would be a better way to do it.

Now it sounds as if there is no output coming from Channel 2. When you have the above problem, what happens when you unplug the Channel 1 banana plug? Can you hear anything? If not, then there is no signal getting to your cabinet. Either the cable or SLA output 2 is not sending a signal.1. combination - I only can hear right speaker and I can control volume level of that speaker only via channel 1
2. combination - I only can hear left speaker and I can control volume level of that speaker only via channel 1
Combinations 1 & 2 - I swapped banana plugs between channel 1 and 2

You have fixed your first problem. Now we just need to fix the second one.
He did (mean + and - reversed for each channel). That put both + signals onto the sleeves of the 1/4" plugs. When they were both plugged into the cab, the cab wiring shorted them together.Yep my mistake.
If he connected the two red inputs with one cable and the two blacks with the other you are completely right
I tought he mentioned the + and - per channel upside down
Is it OK if I hijack this thread a bit with an ART SLA2 related question? I'd just rather not flood the board with more ART related questions.
My issue is this; I have it bridged mono running into my Line 6 4x12 cab @ 8 ohms mono. But it isn't at all as loud as I would have expected considideing it's 560W. It can be loud if I crank up the Channel 1 volume and also the Axe-Fx output.
So I guess there are 2 questions;
1. Could those of you using the ART and the Axe-Fx give me the relative positions of the output on the Ax and the channel 1 volume on the power amp, when you consider it to be quite loud? (i.e 12 o'clock on both?)
2. Perhaps there is a global output setting somewhere in the menu that I'm missing? Granted, there is a difference between some of the patches, but I just would have expected this configuration to be able to keep up with a 50/100W Marshall half stack, and it doesn't unless I have everything totally cranked.
edit: if it would be more appropriate to start a new thread, please let me know and I will do so...
