QSC CXD4.2Q เครื่องขยายเสียง 4 แชนแนล 700 วัตต์

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.

Features

• Seamless Q-SYS integration with audio transport and control via standard Gigabit Ethernet protocols and hardware
• Capable of providing up to 5,000 watts continuous and 8,000 watts peak with 70V or 100V direct drive on each output of the CXD4.3Q and CXD4.5Q, and on bridged output pairs of the CXD4.2Q
• Flexible Amplifier Summing Technology™ (FAST) permits total amplifier power to be distributed across one, two, three, or all four channels
• PowerLight universal switch mode 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
