CM-AESX3 3 Way Passive Digital AES3 Splitter, with XLR

The CM-AESX3 is a passive digital splitter, designed to split a single AES3 source to up to three destinations, using Neutrik XLR connectors. 110Ω termination can be applied, if desired to unconnected outputs. The CM-AESX3 is a single “one-to-three” splitter housed in a small form box, and utilises a locking XLR socket for the input connector.

Connectors & Controls

AES/EBU Input(s)
Both units use a stereo balanced line input on a RCA phono connector with the following connections:
The single digital audio input is via a female XLR connector with the following pin assignment:
Pin 1: 0V Common
Pin 2: Phase
Pin 3: Non Phase

AES/EBU Outputs 1-3
The digital audio outputs are via male XLR connectors with the following pin assignment:
Pin 1: 0V Common
Pin 2: Phase
Pin 3: Non Phase

Termination Switches
It is possible to terminate Output 2 and Output 3 with 110Ω in the event that they are not connected to a destination device. It may be necessary to remove termination from an unused output if a used output is connected to a destination via a long cable run, in order to increase the level of the AES3 carrier signal.
