Properties
Input → complementary crossovers (four cascaded one-pole low-passes, subtracted from the remainder) → 4 bands, each with stereo-linked peak compression, knee and makeup → Mute/Solo/Bypass → Sum → Master Output → Output. The bands sum back to the original signal with compression off; zero latency.
