Calrec Audio

ImPulse is a SMPTE 2110 processing and routing engine that is compatible with existing Calrec Apollo and Calrec Artemis control surfaces. This provides an easy upgrade path for existing Calrec customers as they move across to full IP infrastructures. ImPulse uses Calrec’s powerful Bluefin3 DSP processing which makes ImpUlse the most powerful DSP engine in the world. It can switch between five different user-upgradable DSP packs and future expansion will allow up to 4 independent DSP mix engines to run on a single core simultaneously. ImPulse provides 3D immersive path widths and panning as standard for NGA applications with 3D pan controls, flexible panning and downmixing.
