HD PROCESSING MENU

13  

The HD Processing Menu

Much like the Studio processing core, the optional HD processing section is virtually identical to its AM coun-
terpart with one significant difference: It uses a look-ahead peak limiter in lieu of a clipper as the final processing 
stage. 

The HD processing cores are suitable for use in both HD Radio (iBiquity/NRSC-5) and DAB (Eureka 147) 
applications depending upon the sample rate established in the System > System Config > Sample Rate menu.
