The Q-SYS MPA-Q 8x125 is an eight-channel network amplifier designed for distributed and performance audio systems that need native integration within the Q-SYS ecosystem. It supports Lo-Z, Hi-Z, 70 V, and 100 V direct drive on every channel, allowing system designers to handle mixed speaker loads without relying on manual switching. With eight routable analog line-level inputs and dual gigabit Ethernet ports, it fits applications where networked audio transport and local source access both matter.

This model is well suited to hospitality, entertainment, retail, and government installations where uptime and operational flexibility are critical. Standalone mode enables the amplifier to switch to available analog inputs if network connectivity is lost, while PoE support on LAN A helps restore audio quickly after a power interruption. Four GPI inputs and two NO/NC relays also give integrators additional control options for automated system behavior.

The 2RU full-rack chassis includes hardware for rack or surface mounting, making deployment easier across centralized equipment racks and space-limited installation environments. Analog Mode can bypass networked audio entirely, creating a fully analog amplifier with basic channel setup available from the front panel display.
