Balanced XLR
Balanced analog remains the most universal connection between processor and power amplifier. It is easy to troubleshoot, compatible with almost every premium amplifier and does not depend on network configuration.
AES/EBU
AES3/AES-EBU keeps audio digital over point-to-point balanced connections. It can simplify long cable runs and feed compatible digital amplifiers or converters.
Dante and AES67
Audio over IP can transport dozens of channels over standard network infrastructure, creating far more routing flexibility and reducing large analog looms.
Where the DAC lives
With analog XLR outputs, D/A conversion occurs in the processor. With digital or AoIP outputs, the DAC may move into the amplifier or a downstream interface.
Rack implications
Digital architectures can change cable density, redundancy, amplifier location and service workflow. They also demand stronger networking knowledge.
How to choose
Use analog when universal compatibility and simplicity matter. Consider AES or AoIP when channel count, digital amplifiers, active speakers or rack scale make conventional analog wiring cumbersome.
