Sonifex RB-DDA6A 6 Way Stereo AES/EBU Digital Distribution Amplifier Review
The standard RB-DDA6A is a solid choice for most audio setups, offering smooth distribution and support for both standard and high-resolution signals. But if you're in a situation where backup power matters, the RB-DDA6A-2P model is the way to go. It has two power supplies that keep your system running even if one fails. Plus, it comes with warning lights and an alarm output to alert you when something’s wrong. You stay in control, no matter what.
Standard vs Dual Power Supply Models
The main difference between the standard Sonifex RB-DDA6A and the RB-DDA6A-2P lies in power redundancy. The standard model features a single power input—great for everyday use in controlled environments. In contrast, the RB-DDA6A-2P comes equipped with dual power supplies, allowing it to stay running even if one power source fails. It also includes status LEDs and alarm outputs to alert you of any issues, making it ideal for mission-critical setups where uptime is essential.
