dbx 565 Dual-Chassis Optical Compressor (500-Series Module)

DBX's 565 Dual-Chassis Optical Compressor is a two-channel multi-frequency-band compressor with phantom power that can be used as a dual-mono or stereo unit. It has a 16-stage frequency-range select for processing the low frequencies up to the high-midrange. DBX aims for flat passband processing by using a Linkwitz-Riley 4th-order (24 dB / octave) crossover to avoid partial phase inversion at the output stage.
