2.0 OPERATION
MicroDAC IV promotes ease-of-use by reducing the number of buttons and switches the user
needs to learn. All of the settings that required adjusting internal DIP switches in the previous
version can now be accomplished using a computer. The user configures the filter(s) as
desired using special Windows software, then downloads the settings to the MicroDAC IV
where they are stored in non-volatile memory.
The following section discusses the connections and controls for the unit. The remaining sections
describe typical setups and provide an overview of adaptive filters to ease the selection of the best
filter in a particular situation.
