Klark Teknik DN504 Plus Quad Compressor Limiter
This device provides four channels of full function “quick to set” compression in only one unit of rack space. Its switchable knee function provides for both hard and soft compression styles, with auto attack/release mode for inaudible compression and easy set-up Manual attack/release mode for creating compression effects.
Each channel features separate side chain inputs, gain reduction and output level metering. Advanced VCA design ensures extremely low noise and distortion.
Additional features include stereo link function, which provides two pairs of stereo channels XLR connectors fitted as standard for main audio terminations, with transformer balancing available as an option.
