QSC DPA8.8Qn 8通道数字功放

Features

• Seamless Q-SYS™ integration with audio transport and control via standard Gigabit Ethernet protocols and hardware.
• Capable of providing up to 4,000 W peak and 2,500 W continuous.
• Eight channel DPA-Q models also feature eight channels of mic/line input directly on the back of the amplifier and act as a Q-SYS on-ramps in addition to amplification.
• Touch-proof Euroblock loudspeaker connections.
• Flexible Amplifier Summing Technology™ (FAST) permits up to four channels to be combined for higher output power.
• PowerLight universal switchmode power supply with PFC for highest efficiency, and low weight.
• 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.
