Tascam MM-4D IN Analog Dante-omformer med 4 kanaler, XLR

Tascam ML-4D/IN Analog Dante converter med DSP-mixer

MM-4D/IN er en utsøkt analog inngangsenhet som konverterer fire mic/line-inngangssignaler til fire Dante-utgangssignaler. I tillegg støtter den også firekanals Dante-input, noe som gjør det mulig å bruke praktisk talt alle lydkilder i et etablert Dante-nettverk. Tilgjengelig med Euroblock (MM-4D/IN-E) eller XLR (MM-4D/IN-X) kontakter for analoge innganger, kan denne modellen brukes til et bredt spekter av applikasjoner.

MM-4D/IN er en del av Tascam Dante Compact-processorserien, som består av kompakte lydkonvertere med halv rack til Dante/AES67-nettverk. Modellene kan enkelt legge til ytterligere mic/line- eller AES/EBU-innganger/utganger til Dante-lydnett i offentlige fasiliteter, TV-stasjoner, innspillingsstudioer eller eksklusive hjemmemiljøer og kan kombineres fritt.

En avgjørende fordel ved produktprogrammet er DSP-prosessoren innebygd i hver enhet. Ved å levere ikke bare miksfunksjoner og EQ, men også dynamisk behandling, automatisk nivåstyring, automatisk ducking, routing og støykompensasjon, kan selv små systemer fungere uten ytterligere signalbehandling eller miksere. Fra input av mikrofonsignaler til utgang til aktive høyttalere eller opptaksenheter, kan Dante Compact Processor Series bygge et komplett lite system alene.

Fjernstyring er mulig via to forskjellige programvareprogrammer for Mac, Windows, iOS og Android-enheter: Tascam DCP Connect for konfigurasjon og Tascam EZ Connect for sluttbrukere, som begge er enkle å bruke og inkludert med enhetene. MM-4D/IN gir også mulighet for å dempe sine innganger via GPI.

Alle modeller kan drives av PoE eller en ekstra AC-adapter. Ved bruk av power-daisy-chaining kan to enheter montert side om side i en rack forsynes fra én adapter.
