Overview
The Block 4+ is a Dante 4×4 interface that allows analog input and output signals to be integrated into audio over IP networks.
Its PoE power and terminal-block connectors simplify installation in racks, technical enclosures, or false ceilings without the need for extensive analog wiring.
It is a practical solution for expanding Dante systems with distributed analog connection points.
