{"product_id":"q-sys-qio-flex4a","title":"Q-SYS QIO-FLEX4A Modular Network I\/O Expander for Q-SYS","description":"\u003cp\u003eThe Q-SYS QIO-FLEX4A is a distributed I\/O expander designed for systems integrators building scalable installed audio networks around the Q-SYS platform. By offloading local I\/O from central processing hardware, it allows audio and control connectivity to be placed precisely where it is needed — near displays, room controllers, or compact loudspeakers — without running long analog cable runs back to a core processor.\u003c\/p\u003e\u003cp\u003eThe QIO-FLEX4A is particularly well-suited for conference rooms, hospitality installs, education facilities, and corporate AV deployments where a mix of mic\/line sources, third-party control systems, and small local speakers must be managed from a single device. Its two onboard amplifier outputs eliminate the need for a separate amp in rooms requiring low-wattage reinforcement, while the 4x8 GPIO block and RS232 port handle integration with room controls, lighting systems, and legacy serial devices.\u003c\/p\u003e\u003cp\u003ePowered over Ethernet via PoE+ or an auxiliary 24 VDC supply, the QIO-FLEX4A minimizes infrastructure overhead. Up to four units can be daisy-chained on a single network drop, and up to two can share a daisy-chained DC power feed, making it a practical choice for multi-room rollouts where conduit and cabling are constrained. Management and signal routing are handled natively within Q-SYS Designer Software, keeping commissioning consistent with existing Q-SYS workflows.\u003c\/p\u003e","brand":"QSC, LLC","offers":[{"title":"Default Title","offer_id":52227066855608,"sku":"145113","price":1895.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0871\/7382\/4696\/files\/145113_QSYS-QIO-FLEX4A_ALT01sqr.jpg?v=1784838181","url":"https:\/\/soundpro.com\/products\/q-sys-qio-flex4a","provider":"SoundPro","version":"1.0","type":"link"}
