Is there a way to balance the outputs to the internal speakers and headphone jacks, completely inside the S3000, when both speakers and headphones are used?
I've found playing live that the acoustic piano "Tones" sound great in small cafes and clubs if I use a mixture of the internal speakers plus the L/R lines out to powered speakers. That means setting the S3000 volume control fairly high to get enough internal speaker for the blend.
At the same time, I'd like to use the headphone out for a send of the pure piano source to my IEMs, but the level set by the main volume control (for the internal speakers) is too high. I could send from the headphone jack into another attenuating device or run the main line out into a mixer for separate sends to my external speakers and IEMs. However, is there a way to change the relative headphone jack output with settings inside the S3000, so I could avoid using another device?
