6 Introduction The Q-SYS QIO Endpoints Series offers multiple products that can serve numerous audio and control purposes. ML4i The Q-SYS ML4i is a network audio endpoint native to the Q-SYS Ecosystem, serving as a mic/line input that enables network-based audio distribution. The compact form factor includes surface mounting hardware permitting discreet and strategic mounting while an optional rack kit fits one to four devices into a standard 1U nineteen-inch format. The four-channel granularity locates the right amount of analog audio connectivity in desired locations without bulk or waste. Up to four devices may be daisy-chained off one access switch port, provided 24 VDC power is available. Alternatively, each may be individually powered over Ethernet. L4o The Q-SYS L4o is a network audio endpoint native to the Q-SYS Ecosystem, serving as a line output that enables network-based audio distribution. The compact form factor includes surface mounting hardware permitting discreet and strategic mounting while an optional rack kit fits one to four devices into a standard 1U nineteen-inch format. The four-channel granularity locates the right amount of analog audio connectivity in desired locations without bulk or waste. Up to four devices may be daisy-chained off one access switch port, provided 24 VDC power is available. Alternatively, each may be individually powered over Ethernet. ML2x2 The Q-SYS ML2x2 is a network audio endpoint native to the Q-SYS Ecosystem, serving as a mic/line input, line output device, that enables network-based audio distribution. The compact form factor includes surface mounting hardware permitting discreet and strategic mounting while an optional rack kit fits one to four devices into a standard 1U nineteen-inch format. The four-channel granularity locates the right amount of analog audio connectivity in desired locations without bulk or waste. Up to four devices may be daisy-chained off one access switch port, provided 24 VDC power is available. Alternatively, each may be individually powered over Ethernet. GP8x8 The Q-SYS GP8x8 is a network control endpoint native to the Q-SYS Ecosystem, providing General Purpose Input/Output (GPIO) connections that allow the Q-SYS network to interface with miscellaneous outside devices, such as LED indicators, switches, relays, and potentiometers, and with custom or third-party controls. The compact form factor includes surface mounting hardware permitting discreet and strategic mounting while an optional rack kit fits one to four devices into a standard 1U nineteen-inch format. Up to four devices may be daisy-chained off one access switch port, provided 24 VDC power is available. Alternatively, each may be individually powered over Ethernet. Power Requirements The Q-SYS QIO Series offers a flexible power solution that allows the integrator to choose to use either a 24 VDC power supply or an 802.3af Type 1 PoE PSE. With either power solution, you must follow the safety instructions for the specific power supply or injector chosen. For details on the 24 VDC or PoE power supply requirements, refer to the product specifications. WARNING: To avoid the risk of electric shock, this equipment must only be connected to a supply mains with protective earth when using class I power supply. Power over Ethernet (PoE) NOTE: A device cannot provide daisy-chained power to an external device with Power over Ethernet. An external 24 VDC supply is required for power daisy-chaining applications. A device can provide Ethernet daisy-chaining with either power source. 24VDC External Supply and Daisy-Chained Devices NOTE: When using the FG-901527-xx accessory power supply, up to four (4) devices may be powered.

1 1 Rack Mount Installation Q-SYS QIO Endpoints are designed to be mounted in a standard rack-mount unit using the Q-SYS 1RU rack tray (FG-901528-00). The rack tray accommodates up to four QIO Endpoint units of either product length. Rack Tray Hardware (1x) Rack mounting tray (3x) Blanking plates (14x) M3 x 6 mm flat head screws (4x) Retaining clips Attach the Retaining Clips For each QIO Endpoint you are installing in the tray, insert and attach a retaining clip in either the short or long length location using a flat head screw. Short Length Long Length Attach the QIO Endpoints and Blanking Plates Slide each QIO Endpoint into a retaining clip. Attach each unit with two flat head screws. Optionally attach the blanking plates, each with two flat head screws. NOTE: Blanking plates are optional and can be used to facilitate proper rack airflow. Unused blanking plates can be attached at the rear of the tray if needed, as shown.

12 Surface Mount Installation The QIO Endpoints can also be mounted under a table, on top of a table, or on a wall. For any of these mounting applications, use the surface mounting bracket and pan head screws included with the QIO Endpoint ship kit. The brackets are symmetrical to accommodate mounting right-side up to a ground-facing surface. NOTE: Fasteners for attaching the bracket to a surface are pictured as an example but not provided. Freestanding Installation For freestanding installation on a table top, apply the four adhesive foam spacers to the underside of the unit. Specifications and Dimensions Product specifications and dimension drawings for the QIO Endpoints can be found online at www.qsc.com.
