A&E SPECIFICATIONS—Q-SYS I/O-8 Flex
The network channel expander shall provide remote audio and control I/O to the System Processor leveraging the same native networked audio and control technology as the System Processor. The network channel expander shall operate natively on a standard gigabit Ethernet infrastructure available from a broad range of network infrastructure manufacturers, employing DiffServ quality of service, IEEE 1588-2008 (PTPv2) precision time protocol, UDP/IP audio data transport with floating point format audio data representation. The system shall not require IEEE 802.1AS, IEEE 802.1Qat or IEEE 802.1Qav support on the network infrastructure to function. The overall system latency from analog input to synchronized analog outputs anywhere on the network shall be 3.167ms. The system shall also be able to achieve an overall system latency of 3.167ms over Layer-3 routed network infrastructure without any additional hardware, software or connection services between subnets. 
The network channel expander shall offer eight ‘FLEX’ channels that can be configured in real-time via software as either a mic/line input with +48v phantom power or a line level output with single channel granularity across the bank of eight channels. It shall also offer eight GPI control pins, eight GPO control pins, RS232 on a 3-pin Euroblock connector, Audio-to-USB Bridging via USB Type-B Device port as well as dual redundant networked audio, two USB Type-A Host connectors, 2-pin Euroblock for +24v DC power and PoE+ power via the Q-LAN A network port.
The network channel expander shall have the following front panel controls and indicators: blue monochrome OLED display with page forward capacitive touch button, Unit ID capacitive touch button, Power On blue LED, Two USB A Type ports. The system processor shall provide a monochrome 304x96 blue OLED graphics display displaying the device name, design name and system status, LAN A and B settings, and the firmware version. Device Status shall be displayed on the OLED display including I/O status, muting, level present indication, and system status. 
The network channel expander shall feature multiple mounting options for both under-table, on-wall, in rack (half-rack and full 19” rack widths) as well as the ability to securely mount alongside a companion device using the same mounting scheme to occupy a full, single 1RU rack space. All mounting hardware shall ship with the product.
The network channel expander dimensions shall be: 1.75" x 8.66" x 9.43" (44mm x 305mm x 102mm) 
The system input and output device shall be the QSC Q-Sys I/O-8 FLEX.
