About Audio-Technica LINK
This product can daisy-chain up to eight ATDM-0604a units to support 48 mic/line inputs and 8 unbalanced stereo audio inputs for the entire
system. The proprietary Audio-Technica LINK functionality enables the transmission of low-latency, high-speed audio bus signals between devices,
making it possible to steadily control and transmit uncompressed audio signals.
Furthermore, the model offers excellent workability as it conforms to the Ethernet standards and can be connected to generic LAN cables (shielded
cables of Cat5e or above with the conductor diameter size of 24 AWG or larger must be used).

An unbalanced connection tends to be subject to induction noise caused by the chassis potential differences. Be sure to match the chassis
potentials between devices.
• Match the power supply phases between devices.
• Standardize the power supply systems.
• Connect the GND (ground) terminal or chassis of each device.
Power cable connection
• Connect the power plug to the appropriate outlet with protective grounding. Electric shock may result if the plug is not grounded securely.
How to connect a Euroblock connector
1. As shown in the figure, expose the wires inside the cable.
• Do not solder the stranded wires.
2. Loosen the screws with a flathead screwdriver.
3. Verify the pin assignments, and connect each to the applicable
wire.
