{"product_id":"q-sys-dca1644","title":"Q-SYS DCA1644 4-Channel Cinema Power Amplifier for Theatres","description":"\u003cp\u003eThe Q-SYS DCA1644 is a four-channel power amplifier engineered specifically for cinema sound system installations. It targets integrators and system designers deploying audio in small to medium theaters, where consistent output, compact rack footprint, and compatibility with cinema signal processing infrastructure are non-negotiable. Its 2RU, 14-inch-deep chassis fits console-mounted rack systems without consuming excessive depth, and the 21-pound chassis keeps labor burden manageable during installation and service calls.\u003c\/p\u003e\u003cp\u003eEach unit ships with a DataPort — an HD15 connector per pair of channels — designed for direct interfacing with DCM and DCP Digital Cinema Monitor and Processor systems. This integration point is the key differentiator against general-purpose commercial amplifiers in the same power class: the DCA1644 participates in a complete cinema signal chain rather than functioning as a standalone device, reducing field wiring complexity and system integration labor. Gain control security covers prevent accidental misadjustment in unsupervised booth environments, and active inrush limiting protects facility circuit breakers during power-on sequences.\u003c\/p\u003e\u003cp\u003eFor system designers working with tri-amp configurations in larger venues, the DCA1644 handles mid and high-frequency duties with AB+B output circuitry, a damping factor exceeding 500, and full protection against short circuit, open circuit, thermal, ultrasonic, and RF faults. Bridged mono mode extends output capacity for demanding applications, and per-channel DIP switch control over clip limiting, LF filtering, and input mode gives engineers the flexibility to tune behavior at the rack without additional outboard gear.\u003c\/p\u003e","brand":"QSC, LLC","offers":[{"title":"Default Title","offer_id":52444430696632,"sku":"119384","price":1675.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0871\/7382\/4696\/files\/119384_QSYS-DCA1644_ALT01sqr_5097031a-2ab5-4954-9a4d-b0f4194c940f.jpg?v=1784835080","url":"https:\/\/soundpro.com\/products\/q-sys-dca1644","provider":"SoundPro","version":"1.0","type":"link"}
