The DN500 Plus series utilises a ?THAT's? chip which features lower distortion, improved dynamic range and faster slew rate.
The DN504 Plus Quad Compressor has enjoyed hugely increased popularity in recent years, due to the ever expanding use of in-ear monitor systems. This is because the unit can be configured into two stereo pairs, has all the superlative audio performance of the DN500 Plus, and fits two sets of stereo compression into just one rack space. This configuration also makes it extremely cost effective.
Overview
Four channels of full function ?quick to set? compression in only one unit of rack space.
Switchable knee function provides for both hard and soft compression styles
Auto attack/release mode for inaudible compression and easy set-up
Manual attack/release mode for creating compression effects
Advanced VCA design for extremely low noise and distortion
Separate side chain inputs are provided for each channel
Gain reduction and output level metering is provided for each channel
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
