Tascam line converter 8 kanaler balanceret / ubalanceret

LA-80MKII er en 8-kanals linjeniveaukonverter bygget til konvertering i studiekvalitet mellem ubalancerede (–10 dB) og balancerede (+4 dBu / –20 dBu) linjeniveauer, hvilket giver ideel integration af alle typer udstyr. LA-80MKII tilbyder otte ubalancerede RCA-indgange og otte balancerede XLR-udgange. Den har en switchmatrix, der gør det muligt at forbinde kanaler, og bruger enheden som en distributionsforstærker til at opdele signaler til flere optagere eller til multi-zone lydrouting-applikationer.


Switche på bundpanelet giver mulighed for at vælge et nominelt niveau på +4 dBu eller –20 dBu for hver kanal, og ±12 dB trim-pots på frontpanelet gør perfekt niveautilpasning nem. LED'er på frontpanelet indikerer signaltilstedeværelsen for hver kanal. Ground lift-switche er tilgængelige på hver kanal og globalt for at eliminere ground loops.

8 channels with unbalanced RCA inputs and balanced XLR outputs
XLR nominal level selectable between +4 dBu and –20 dBu
