The Avid S3 user guide explains installation, setup, and operation of the Pro Tools | S3 studio controller and AVB audio interface.
The Avid S3 is a studio controller and Ethernet AVB 4‑in/6‑out audio interface that integrates with Pro Tools and other EUCON‑compatible applications. This guide covers hardware connections, EuControl software installation, firmware updates, and how to enable AVB audio for low‑latency operation.
It also details the S3 platform controls, audio I/O configuration, and compliance information, providing step‑by‑step instructions for both studio and live modes. This manual is written in Chinese.
| Audio I/O | 4 inputs / 6 outputs |
|---|---|
| Ethernet bandwidth | 100 MB/s |
| Power cable type | IEC |
| Network cable requirement | Cat 5e (350 MHz) shielded |
Connect the power adapter, then plug an Ethernet cable from any S3 Network port to a free Ethernet port on the computer (or use a Thunderbolt‑to‑Ethernet adapter).
The EuControl software must be installed on the workstation computer before the S3 can be used.
Enable AVB audio on the workstation computer; AVB audio is required for the S3’s built‑in audio I/O to function.
