1) ADAT-4 Model— the “A” model has AES3 outputs (XLR), and the “B” model has AES3id
outputs (BNC).
2) Power Connector — accepts the power jack from the 6 VDC power supply. Refer to
“External Power” for more information regarding external power.
3) AES OUT 1 — output #1 is standard AES audio, either AES3 (XLR) for the A model or
AES3id (BNC) for the B model. The output is locked to the ADAT input.
4) AES OUT 2 — identical in function to output #1.
5) AES OUT 3 — identical in function to output #1.
6) AES OUT 4 — identical in function to output #1.
An internal jumper allows the outputs to have 20 or 24 active bits. In 20-bit mode, each output’s
auxiliary data bits will be set to zeros. Output channel status bits will reflect the 20/24-bit mode
setting. Refer to the “ADAT-4 Internal Jumpers” for instructions on all jumper settings.
ADAT-4 Installation
This section provides instructions for connecting power, digital inputs. and digital outputs.
Connecting Power
Plug a 6 VDC power supply (rated at 200 mA or greater) into the appropriate voltage outlet for
your specific country, and connect the end of the cord into the ADAT-4 jack marked +6V. Secure
the locking ring finger tight. The green PWR LED lights when power is applied.
Connecting the ADAT Input
The ADAT optical input includes eight audio signals with synchronization words, auxiliary data
bits (currently all zeros) and clock extraction bits to conform to the ADAT format. Using an
approved 1-meter (or less) ADAT cable, connect the desired ADAT source to the ADAT-4’s input
connector.
Connecting AES Outputs
Connect the digital audio output from one of the four AES OUT connectors, and route it to the
input of the desired destination device. Repeat the procedure for all digital outputs as required.
Refer to the “ADAT-4 Specifications” section for a table of ADAT-4 channel routing.
