dBTechnologies presents A2Net, a new digital audio and control protocol that enables efficient and reliable signal transmission over a single cable. The first devices compatible with A2Net are the new Control24A controller and the ACU-1 expansion card.
A2Net is an evolution of the proven RDNet protocol, allowing the transmission of up to four channels of high-resolution digital audio as well as control data over a single CAT-5 cable. This significantly reduces cabling requirements, making system setup more streamlined and efficient.
The signal transmission follows a classic point-to-point cabling architecture, utilizing CAT-5, CAT-6, or CAT-7 cables. For additional reliability, an analogue XLR connection serves as a redundant backup. In the event of a digital signal failure, the system automatically and seamlessly switches to the analogue signal without audible interruption.
A2Net – Key Features
✔ Digital audio and control signal transmission over a single cable
✔ Seamless integration & backward compatibility with RDNet
✔ Reduced cabling for efficient system setup
✔ High operational security through redundant signal paths
✔ Full control via Aurora Net
✔ “True Bypass” function for uninterrupted audio signal flow
Control24A – Central Control for A2Net Networks
The Control24A is the first dBTechnologies control unit designed natively for A2Net. It integrates audio and network management into a compact solution, expanding RDNet functionality with digital audio transmission.
• Controls up to 64 speakers equipped with ACU-1 cards
• Connectivity via USB-C or TCP/IP (EtherCON)
• Four XLR inputs, configurable as analogue or AES/EBU digital inputs
• Two XLR outputs for AES/EBU digital audio, allowing daisy-chaining of additional units
• Two CAT-5 outputs for A2Net connectivity
• 1.54” E-Paper display for status information, visible even when powered off
• Redundant power supply for maximum reliability
Control24A – Key Features
✔ Central control unit for A2Net networks
✔ 4-channel analogue or 2-channel AES/EBU digital inputs (automatic detection)
✔ Compatible with RDNet control for non-A2Net products
✔ Controls up to 64 speakers with ACU-1 cards
✔ Compact ½ 19” rack design
ACU-1 – A2Net Expansion for dBTechnologies Speakers
The ACU-1 card enables A2Net integration for speakers equipped with DIGIPRO G4 amplifier modules.
A2Net ensures a high level of operational security by automatically switching to analogue inputs and outputs as a backup in case of a digital signal failure. The “True Bypass” function guarantees that the audio signal continues to flow even if a speaker in the signal chain loses power.
The system is fully compatible with RDNet, allowing hybrid setups where both RDNet and A2Net devices can be used together. Control is managed via Aurora Net software, providing an intuitive and precise interface for all system parameters.
ACU-1 – Key Features
✔ A2Net protocol for speakers equipped with DIGIPRO G4
A2Net and the Control24A will be available worldwide starting February 28, 2025.
