The DL441 Quad Auto Compressor/Limiter captures four channels of Drawmer's innovative DL241 'Auto Compressor' in only 1U of rack space. The inclusion of new sophisticated 'automated' circuitry allows the engineer to precisely control both the dynamic range and 'absolute' peak level of the programme instantly, without sacrificing essential control parameters. This perfect balance of features makes the DL441 ideal for use in sound reinforcement and outside broadcast applications where an economy in rack space is essential. Each channel combines a fully professional 'Auto Attack/Release' Compressor with a variable threshold 'Peak Level' Limiter on the output providing a transparent 'endstop'. High resolution bar-graph displays on each channel allow gain reduction and output level to be viewed simultaneously, of particular importance in darkened concert hall or control room situations.
