DPA4.5Q
FEATURES
- Seamless Q-SYS integration with audio transport and control via standard Gigabit Ethernet protocols and hardware.
- Capable of providing up to 5,000 W continuous and 8,000 W peak.
- Flexible Amplifier Summing Technology™ (FAST) permits total amplifier power to be distributed across one, two, three or all four channels.
- PowerLight universal switchmode power supply with PFC for highest efficiency, improved audio performance, and low weight.
- Mic/Line input Euroblock connectors and touch-proof Euroblock loudspeaker connections.
- Eight bi-directional GPIO connections that can be used for analog or digital inputs or outputs to/from Q-SYS.
- Built-in energy saving modes ensure that the amplifier will draw the minimum amount of AC power while still providing outstanding audio quality.
- Q-SYS technical support is available 24/7 - worldwide
