Systemforstærkere DI-2.4000

Varenummer: 6012-XXXXX

DI-2.4000 er en digital 4-kanals forstærker fremstillet i Tyskland. De DSP-forstærkere, der er udviklet og fremstillet af Fohhn, har en høj effekttæthed og en fremragende lyd. Forstærkerne er beregnet til mobile lydsystemer og fast installation. De har alle de vigtigste funktioner og næsten ubegrænsede tilslutningsmuligheder med hensyn til lydindgange. Uanset om det er AES/EBU, Dante eller analogt - de tilbyder maksimal fleksibilitet takket være udskiftelige tilslutningsmoduler. De tilsvarende højttalerforindstillinger sikrer optimal ydeevne og pålidelighed.
