What is a variable coefficient (VC) digital filter?
CD players use digital filters to eliminate the noise
generated during sampling. You can change the tone of
your music by changing the cutoff characteristics of the
digital filter. This unit has four types of filters with
different coefficient characteristics: "Plain," "Analog A,"
"Analog B," and "Standard."
