I've only done this on an SP13000 and I'm now trying it on a EN15000. Both the SP and EN have the same type of screens. Now, the only difference that I see from the instructions and the actual screen on these motherboards is the below:
There is no Front Speaker option on this step and no 5.1, it only has the Master Volume with no 5.1 option.
Even so, I managed to get my SP13000 working after hours of playing around with it. What I found is this:
The amp that I was using is a 2/4 channel amp with a selector switch. When the switch was set to 4 channel, only two speakers would work. When set the switch to 2 channel, all the speakers would work.
Now, I'm working on my friend's setup that the amp is a 2/3/4 channel. This amp does not have a selector switch and I'm having the issue that sound is only coming out of two speakers. How will I set the amp for 2 channel to see if that works? Would I have to use only two RCA outputs from the amp and use a Y adapter?
