 Parametric Equalizer
Click the Crossover Processor [PEQ] button to open the window. Parametric equalization is
provided for each crossover band.
*1 APF: The APF (All Pass Filter) is a filter that passes all frequency bands while affecting only the phase. This is mainly used to
correct the phase at the crossover band.
APF 1st will invert the phase at the specified frequency by 90° and for entire frequency bands by 0°–180°, while APF 2nd will
invert the phase at the specified frequency by 180° and for entire frequency bands by 0°–360°. For APF 2nd, you can adjust the
Q setting.
*2 Horn EQ: CD (Constant Directivity) horn speakers exhibit a roll-off in high-frequency level.
Horn EQ is provided to compensate for this roll-off. For this reason the gain can only be set to higher than 0dB, and the
frequency higher than 500Hz.
