Dynamics III : Dynamics III Side-Chain Input(Compressor/Limiter Only) : Dynamics III Side-Chain Controls : Dynamics III Side-Chain High-Frequency (HF) Filter Type
 
Dynamics III Side-Chain High-Frequency (HF) Filter Type
The HF filter section lets you filter higher frequencies out of the side-chain signal so that only certain bands of high frequencies or lower frequencies pass through to trigger dynamics processing. The HF side-chain filter is switchable between Band Pass and Low Pass filters.
Band Pass Filter
Makes triggering of dynamics processing more sensitive to frequencies within the narrow band centered around the Frequency setting, and rolling off at a slope of 12 dB per octave.
Band-Pass filter
Low Pass Filter
Makes triggering of dynamics processing more sensitive to frequencies below the Frequency setting rolling off at a slope of 12 dB per octave.
Low Pass filter
