Fully differential XLR input enables flexible configuration for single-ended or unbalanced sources, preserving source integrity
Controlled common mode voltage prevents power supply bus pumping, ensuring stable amplifier operation
Four independent ultra-low noise voltage regulators power both analog and digital circuits, minimizing noise and interference
Selectable gain options (11.6 dB, 13.0 dB, 13.2 dB) allow precise amplifier gain customization for different audio setups
Plug-and-play connection with Hypex SMPS1200 power supply simplifies installation
