XPS 4K DSP forstærker
XPS 4K er en firekanals effektforstærker med avanceret processorkraft og analoge/digitale routingmuligheder til krævende installationslydapplikationer. Med 4x1000 W Klasse D kontinuerlig effekt ved 4 ohm, 40-bit floating-point-processorkraft ved 96 kHz og 32-bit intern routing har XPS 4K en bemærkelsesværdig effekttæthed i et 2U-kabinet. XPS 4K er designet til installationslydsystemer af høj kvalitet og er beregnet til brug med højtydende højttalere.
Den tilbyder brugsklare konfigurationer og forudindstillinger. Den kan også bruges i lineær tilstand med avancerede tuningfunktioner. Hver udgang har: 4000 ms udgangsforsinkelse (1372 m / 4501 ft), EQ-filtre, delefiltre, FIR-filtre, multibåndskompressor, RMS-limiter og termisk limiter. XPS leverer brugervenlig premium-lyd med fuld RDNet-fjernstyring, stor indbygget touch-grænseflade, exceptionelt signal/støj-forhold, ultralav forvrængning og ekstremt dynamisk område.
