RCF PR4093

PR4093 er designet til at give en fleksibel løsning til paging- og musikapplikationer i PA-systemer. Den har 6 balancerede inputs mic/line med mulighed for Phantom-power.
Det første input har prioritet som aktiveres af et VOX-kredsløb. 3 stereo-input på RCA-stik er tilgængelige.
Outputs giver forskellige funktionaliteter som tone-kontrol på frontpanelet, dedikerede mixing af inputs 1-6 og forbindelse til optagelsesenheder.
