Beautiful place to play!!!
On my S979, I put my mixer on the right speaker. Only because of being able to access the WAV file player on my Sonar (Roland) VS-100. Under the mixer, I put a non-skid piece of rubber so it doesn't slide off.
I put a 1/4" headphone adapter in the headphone jack to cancel the speakers. Then I just monitor through my DXR10s. I want to hear what my audience is listening to.
DNJ... Do you cancel out the internal speakers since you have the mixer in the left speaker?!?
I never cancel the onboard speakers, I never have a problem hearing the mains ... I put gel feet on bottom of the mixer also so it doesnt slide.
