D&B Audiotechnik Z4011.000 DS20: The Ultimate Audio Network Bridge
• Connects Milan networks to AES3 digital audio signals effortlessly.
• Distributes Ethernet control data with ease.
• Ideal for both mobile and installation setups!
This 1 RU device seamlessly integrates into the d&b system, right in front of the amplifiers in the signal chain. It sends metadata like Milan channel labels and cabling info via the AES3 channel stream to the d&b four channel amplifiers.
With its fully AVB-enabled 5-port switch, it offers a primary and redundant network for the Milan protocol. This gives you extended connectivity to control the d&b amplifiers using the R1 Remote control software via the OCA protocol, all through a single Ethernet cable.
The front panel matches the d&b Touring rack assemblies' I/O panel for easy integration. And it has a power supply suitable for 100 V – 240 V, 50 – 60 Hz mains voltages, with up to 400 V overvoltage protection.
Features:
- • Bridges Milan audio and d&b amplifiers' AES3 inputs via Ethernet.
• Integrated 5-port switch offers extended connectivity and is AVB-enabled.
• Four AES3 input channels for more flexibility.
• Acts as an AES3 distribution device in bypass mode.
• Sends Milan metadata including channel labels through AES3 stream to d&b amplifiers.
