What is the fourth DIP switch for?
Nothing, it is reserved for future expansion.
What adjustments do I need to make during use?
None. Once the NES10-2 is set to your personal settings no further
adjustments should be necessary.
Can the speakers be used with a switch mode
power supply?
No. The speakers shouldbe used with linear suppplies.
Sometimes I can hear watery noises.
When listening to high levels of noise, on high levels of processing
the background may sound a little strange. This is normal operation
as the DSP is removing the high levels of noise.
