*1 APF: The APF (All Pass Filter) is a filter that passes all frequency bands while affecting only the phase. Used to match the
phase of the crossover bands.
APF 1st shifts the phase from 0° to 180°, while APF 2nd shifts the phase from 0° to 360°. APF 2nd also allows Q adjustment.
*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.
