Normally it's no problem as long as you have
inputs/channels enough to handle this.
If you have 4 ch. then use 1 and 2 for keyb.1
and 3 and 4 for the second.
Or 1 for mic, and 2 and 3 for keyboard, or
you can use mono output from keyb., then you
have to use only 2 channels.

You can even connect the VA to the inputs on
the KN6500, and then the sound goes to the
line-input you have KN connected.

A good solution is maybe to use a mixer to
plug in keyboards, mic, guitar or what you want,
and then connect to the amp.
