The MPA-Q 4x250 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.


特徴と利点

  • Four (4) 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)
  • Four (4) analog, line-level audio inputs, fully routable into Q-SYS or direct out
  • 2 ギガビット イーサネット ポートにより、冗長ネットワーク オーディオを実現
  • 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
  • Rightsized for medium-to-large spaces: MPA-Q Series introduces a new mid-power tier to the Q-SYS network amplifier portfolio and is ideal for spaces where high-output amplifiers exceed operational needs, like hospitality and retail facilities, entertainment spaces and larger corporate and government environments.
  • Adapt to keep audio flowing: Ensure your audio system stays running with minimal interruptions. If network connectivity drops, MPA-Q Series amplifiers offer the ability to automatically switch the source to available analog inputs to maintain sound continuity. In the event of a power outage, network audio can be restored within seconds if a PoE connection is available.
  • Venue-wide audio with Q-SYS: MPA-Q Series network amplifiers extend a seamless Q-SYS experience to even more spaces, delivering native audio routing and control in both distributed and performance audio applications throughout your venue.
  • Integrated audio, video and control: MPA-Q Series network amplifiers are driven by the Q-SYS Full Stack AV Platform, which unifies data, devices and a cloud-first open architecture to deliver a fully integrated audio, video and control solution that offers simpler integration and software-based scalability.

*All specifications are subject to change without notice.
1. Max Power - 20 ms , 1 kHz sine wave burst; this data is most useful for asymmetrical loading of amplifier channel and maximizing power utilization of the amplifier.
2. Continuous power: 20 Hz - 20 kHz bandwidth, all channels driven with same load; this data is most useful for estimating longer-term power output across all amplifier channels.
