Chapter 1: ADA4 Introduction Overview The ADA4 is a 4 channel audio converter which can be configured as a 4 channel A/D, a 4 channel D/A, or 2 channel A/D and 2 channel D/A. The ADA4 can accept a AES11, wordclock, or video sync/color black reference input for synchronization. Reference input and synchronization is automatic. Audio levels are configurable via DIP switch control. NOTE: The information in this manual is for ADA4 converters with Serial Number H43000 or Later.

User Controls The user interface for the ADA4 is a 4-switch DIP accessible through a cut-out in the bottom of the unit, and an internal 3-position jumper block accessed by removing the ADA4 cover (secured by 4 screws). Use the jumper to configure the mode of operation (Normal or Synchronizer). Then use the DIP switches—if necessary— to configure channels and audio levels. Factory default switch settings are Normal Mode (jumper installed) and all the DIP switches in the leftmost position.
Chapter 2: ADA4 Operation Internal Jumpers Jumpers inside the case determines whether the unit operates as an AD/DA audio converter (Normal mode, the default setting) or as a Synchronizer, and whether the ADA4 Mini-Converter’s digital outputs are 48k (the default setting) or 96k. NOTE: If you will be using the ADA4 as an A/D D/A converter with 48k outputs, no jumper changes are required. Configuration is accomplished using the external DIP switches.
