QSC CXD8.4Qn เพาเวอร์แอมป์ลายน์ 70V/100V 2 ชาแนล 500 วัตต์ Powered Mixer จากแบรนด์ QSC
QSC CXD8.4Qn
Networked Amplifier
คุณสมบัติ
- 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 with Low-Z, 70V, or 100V direct drive available on all channels.
- Eight-channel CXD-Qn models are “network input only” (no analog inputs) to reduce system cost.
- 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.
