DPA-Q Series network amplifiers combine the QSC legacy of robust power amplifiers, advancements in high-efficiency output devices and native network transport, control and monitoring capabilities of the Q-SYS Ecosystem.
Features
- Seamless Q-SYS Ecosystem integration with audio transport and control via standard gigabit Ethernet protocols and hardware
- Capable of providing up to 4,000 W of power
- Hybrid circuit topology mixing the robustness of the PL380 PowerLight™ amplifier platform with new high-voltage output devices
- FlexAmp™ allows for asymmetric power distribution across amplifier channels
- Flexible Amplifier Summing Technology™ optimizes for either higher voltage loads (up to 200 Vrms output) or high current loads (up to 35 A)
- PowerLight universal switchmode power supply with PFC for highest efficiency, improved audio performance, and low weight
- “Q” models offer mic/line inputs into the Q-SYS Ecosystem; “Qn” models are “network input only” to reduce system cost
- Touch-proof Euroblock loudspeaker connections
- Eight bi-directional GPIO connections plus relay
- Automatic energy saving modes ensure that the amplifier will draw the minimum amount of AC power while still providing outstanding audio quality
