LDP-8242 User Manual (Iss. 03)

Functional Block Diagram

The base model LDP-8242 provides Linear Acoustic™ loudness processing with frame sync, 
video processing, embedded audio support, and timecode support. (

Figure 1.1

) The various 

options are described in detail in the section “

Video and Audio Options

” on page 1-3, and as 

applicable throughout this manual.

This section provides a functional block diagram that outlines the workflow of the LDP-8242. 
Note that signal connections shown depicts full input/output capability. Practical input/output 
signal availability is determined by the licensed features installed.
