→Dual Output
There are two ways to route the output. Both involve some trade-offs.
''The simplest is to use the FX Loop effect block. '' Place the FX Loop at the end of either one of the channel paths, right before the mixer. At the mixer, mute the channel with the FX Loop to guarantee no signal is passing through. For the other channel, set the pan to full center - this allows both sides of the stereo spectrum for that channel to pass through to the analog outputs on the unit.
Cannot find image.
The upside for this method is that you get two stereo outputs (FX loop send is a stereo output). Also, if you don't want to use multiple/special cables to extract the stereo output, you can just use a single 1/4" unbalanced cable for each signal to get mono output. The downside is that you need to place the FX Loop before the mixer, so you have to apply any post-amp effects twice - once in each channel, which can run into DSP limit errors.
''The other method is to use the mixer to pan each signal full left and right and not bother using the FX Loop. '' Then the two sides have different processing.
The upside is you can use (some) effects after the mixer, avoiding DSP limit errors. The downside is that they have to be true stereo effects, or the two signals will be mixed to mono. Also, you have to make sure you use 1/4" output cables in both the left and right outputs. If you just plug into 1/4" left or 1/4" right but don't insert a dummy cable into the other output, the unit will sum the stereo signal into a mono output. But you don't need to run the other cable to anything - just make sure it's plugged in. This isn't the case for the XLR outputs, though, which never sum to mono.
