Overview

The MPA-Q 8x250 is part of the mid-power tier in the Q-SYS network amplifier portfolio, extending native Q-SYS integration into even more performance and distributed audio applications across hospitality, entertainment, retail and government environments.

Features

  • Eight (8) output channels at 250 W per channel
  • Lo-Z, Hi-Z, 70 V and 100 V direct drive available on all channels (no bridging or manual switches required)
  • Eight (8) analog, line-level audio inputs, fully routable into Q-SYS or direct out
  • Two (2) gigabit Ethernet ports for redundant networked audio
  • Standalone mode offers ability to switch to available analog inputs if network connectivity drops
  • Quick audio restore after a power outage if PoE connection is available
  • Four (4) GPI inputs and two (2) NO/NC output relays
  • Full-rack width, 2RU form factor and included hardware for rack- or surface-mounting
  • Analog Mode bypasses networked audio and creates a fully analog amplifier; front panel display allows basic channel configuration in this mode
