After making some critical tweaking adjustments to the Tyros 2 VH, I'm having no problems using it at all.
These adjustments include, Bal-20/Vibrato 0
/Mic gain pod in rear 9 oclock/Voc range set to LOW/Master Mic Vol knob 12 oclock/Mic Vol 127/ Mens Choir.
This combined with my own personal Mic Mixer settings does the job.
