Filter; System - Datavideo AD-300 Instruction Manual

Filter

Other than the dynamic effects, AD-300 also offers audio filters to allow either high or
low frequencies to pass through.
A low-pass filter attenuates content above a cutoff frequency (threshold frequency),
allowing lower frequencies to pass through the filter.
A high-pass filter attenuates content below a cutoff frequency (threshold frequency),
allowing higher frequencies to pass through the filter.
