AES59
AES59 defines the pin-out and wiring standard for AES3 digital audio signals when transmitted over DB25 (D-sub) connectors. It ensures that multi-channel AES3 connections (typically 8 channels in and 8 channels out) are interoperable between different manufacturers’ equipment — such as audio interfaces, consoles, and recorders.
- Connector type: DB25 (25-pin D-sub)
- Standardized mapping: Matches the TASCAM analog DB25 pinout, but carries digital AES3 signals instead of analog audio.
- Purpose: Provides a consistent way to connect multiple AES3 channels through a single cable.
AES - Each DB25 port carries 8 channels (4 stereo pairs), so two DB25 connectors provide up to 16 channels of AES3 digital audio
