QSC Q-SYS MPA-Q 4x250 4-Channel 250W Network Amplifier
- Four 250W Output Channels
- Lo-Z, Hi-Z, 70V and 100V Direct Drive
- Dual 1GbE Network Connectivity
- Native Q-SYS Audio and Control Integration
The QSC Q-SYS MPA-Q 4x250 is a four-channel network amplifier designed to extend native Q-SYS integration into distributed audio and performance applications. It delivers up to 250W of maximum power per channel and supports Lo-Z, Hi-Z, 70V, and 100V direct drive without requiring bridging or manual output-mode switches.
Each amplifier channel includes a dedicated analog line-level input that can be fully routed into Q-SYS or used directly with the amplifier. This provides flexible connectivity for systems that combine networked audio with conventional analog sources.
The MPA-Q 4x250 includes dual 1GbE Ethernet ports for redundant networked audio and provides four GPI inputs plus two NO/NC output relays for control integration. Its Standalone Mode can automatically switch to available analog inputs if network connectivity is lost, helping maintain audio continuity.
The amplifier also supports rapid audio restoration after a power interruption when a PoE connection is available. With its 2RU form factor and removable rack ears, the MPA-Q 4x250 can be rack- or surface-mounted in professional AV installations.
