Stereo AND mono output for NS4

[That1Guy]

I am now the proud new owner of a NS4. I upgraded from an electro.
According to the manual, outputs 1 and 2 are also routed to the left and right on the headphone jack.
I am trying to send a mono signal out (maybe on output 3) while still retaining stereo on 1 and 2 for headphones.
The only way I have made it work is to run separate left and right out into a physical mixer and sum it to mono there.
Am I missing something? The electro 6 had a mono switch for the output while still retaining a stereo image in the headphone jack.

Looks like you can do what you want, at least based on my reading of the manual on page 58

Unfortunately it doesn’t have both a stereo AND mono out at the same time. Luckily I have an old passive mixer that does the job. I just plug outs 1 and 2 into it and have a single out on the mixer to my DI.

I still don't understand..... I would like to hear the keyboard and the sounds set in mono to understand some things... is it possible or do I have to hear the left channel with a jack and if I change and put it on 2 the right channel!! Is it possible that you can't set the whole ns4 in mono!??

Left (or right) channel only is not really the "mono version of the stereo output" but just a monoaural signal of the left (or right) channel information.
Think on the basis of the "auto pan" effect. If you hear only one of the channels, you should hear a 'tremolo' effect (volume up and down). If you sum the two L & R signals (mono) you would not hear any effect, while in the stereo version the sound would be bouncing between channels. Three different situations.

I'm also interested in having 1&2 in Stereo (for FOH) and e.g. Out 3 in Mono (for monitoring). If I understand the discussion correctly that is not possible without external gear? Any further ideas?
Thanks
