Digital loudspeaker management system is compact and powerful DSP based 2-in 4-out audio processing unit, ideally suited to live sound and fixed installation applications and designed for use with Turbosound loudspeakers and associated bass enclosures and subwoofers. It combines functions of multiple conventional products in compact 1U high, 19-inch high rack unit. It provides tailored equalization and crossover functions specific to Turbosound loudspeaker systems. To achieve this, it provides two inputs and four outputs, configured by factory presets, in addition to total of 40 user-defined presets to enable use with variety of loudspeakers. High performance limiters, delays (up to 400ms input, 80ms output), equalization, gain, polarity and crossover filter controls are accessible to user in order to match specific operating environments. It provides exceptional audio quality through use of carefully optimized processing and high performance converters for better than 111dB of dynamic range, 96kHz sampling rate and minimal filtering. It employs audio-grade capacitors in the analogue signal path for true audiophile performance and superior accuracy. It features LF shelving filters to allow adjustment of response in order to match variations of acoustic conditions such as half space environments like floor monitor applications or for close coupling of loudspeaker arrays. Input delays of up to 400ms and output delays of up to 80ms can be set up on each output (mono) or pair of outputs (stereo) with fine resolution of 21µs steps to ensure perfect driver alignment.
