DPA-Q Series

Designed specifically for use with Q-SYS, DPA-Q amplifiers marry the exciting new amp technology found in the DPA platform with the powerful Q-SYS network processing and control system to create the ultimate audio routing and power solution for cinema sound applications. 

The DPA-Q line includes three models (DPA 4.2Q, DPA 4.3Q & DPA 4.5Q) capable of delivering robust, high-fidelity power to drive a wide range of loudspeaker configurations. By simply connecting the amplifiers via standard layer 3 Ethernet, the Q-SYS Core can route digital audio to/from the amps, as well as provide total control and monitoring of all amplifier functions. Flexible Amplifier Summing Technology™ (FAST) actively distributes total amplifier power across one, two, three or all four outputs, enabling amp channels to be paralleled or bridged for maximum current and voltage output.

Flexible Amplifier Summing Technology™ (FAST) permits total amplifier power to be distributed across one, two, three or all four channels.

As Q-SYS network peripherals, DPA-Q amplifiers simplify and streamline systems for channel- and object-based immersive sound formats, including Dolby® Atmos™ and DTS:X.

Version 4.0 (and higher) of Q-SYS Designer includes DPA-Q amps in the inventory and provides complete system-wide design, control, and monitoring capability

GPIO ports on Euroblock connectors enable additional functionality utilizing the intuitive and powerful Q-SYS control engine complete with logic functions and LUA scripting.

Built-in energy saving modes ensure that the amplifier will draw the minimum amount of AC power while still providing outstanding audio quality.

With redundant Ethernet jacks, the DPA-Q amps seamlessly integrate with Q-SYS providing audio streaming directly to and from the amplifiers.
