QSC CXD8.4Q
Network Amplifiers
Designed specifically for use with the Q-SYS™ platform, CXD-Q amplifiers marry the new amp technology found in the CXD platform with the powerful Q-SYS network processing and control system to create the perfect solution for installed applications.
The CXD-Q line includes seven models, three four channel (CXD4.2Q, CXD4.3Q and CXD4.5Q), and four eight channel (CXD8.4Q, CXD8.4Qn, CXD8.8Q, CXD8.8Qn).
All these amplifiers are capable of delivering robust, high-fidelity power to drive a wide range of loudspeaker configurations including 70V and 100V systems.
The “Q” models offer mic/line inputs into the Q-Sys eco-system, while the “Qn” eight channel models provide no analog inputs thereby reducing the overall system cost.
By simply connecting the amplifiers via standard Layer 3 Ethernet, the Q-SYS Core can route audio to/from the amps, as well as provide total control and monitoring of all amplifier functions.
Flexible Amplifier Summing Technology™ (FAST) is available on all models and allows the integrator to combine one, two, three or up to four amplifier channels together for maximum current and/or voltage output.

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-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.
