The peripheral shall support a four (4) channel total analog I/O capacity and shall be presented as 4 Flex Channel I/O which shall be software definable as analog input or outputs in single channel increments with any combination. Analog audio inputs shall be remotely configurable for microphone or line-level signals. These inputs shall be fully monitored and supervised with configurable impedance measurement to detect connected devices with the ability to drive programmable logic or scripted programming. In addition to the Flex Channel I/O, the peripheral shall provide two (2) amplifier channels capable of driving up to 10W per channel depending on the power source and load impedance. The peripheral shall accommodate up to six (6) networked audio channel outputs and up to four (4) networked audio channel inputs, formatted as Q-LAN networked audio, between the system processor. 

The peripheral shall provide four (4) general-purpose inputs and eight (8) general-purpose outputs that are remotely configurable, providing an interface for LED indicators, switches, relays, potentiometers, and custom or third-party controls to the peripheral. The collection of inputs and outputs shall have an individual +12 VDC terminal (up to 100mA available for each type, protected by a self-resetting fuse) and ground reference for use with potentiometers (input), relay coils and LEDs (output), or other purposes. Inputs and outputs shall be independently configurable from the system processor.  

The peripheral shall operate natively on a standard gigabit Ethernet infrastructure available from a broad range of network infrastructure manufacturers. The peripheral shall employ DiffServ quality of service, IGMP, IEEE 1588-2008 (PTPv2) precision time protocol, and UDP/IP audio data transport with floating-point format audio data representation. The peripheral shall support 802.1x authentication. The peripheral 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 3.167 ms. The system shall also be able to achieve an overall system latency of 3.167 ms over Layer-3 routed network infrastructure without any additional hardware, software, or connection services between subnets.

The peripheral shall operate on PoE, PoE+, or DC power and have the following front panel controls and indicators: Unit ID button, green ID LED, and blue Power LED. A web interface shall provide basic network and security configuration, status, and log retrieval. The peripheral shall be natively integrated into Q-SYS Designer Software for network discovery, real-time configuration, control, monitoring, supervision, and network audio routing.

The peripheral’s rear panel shall provide two 2-pin power Euroblock connectors for daisy-chainable DC power, four (4) Flex audio channels on a single 12-pin Euroblock connector, two (2) amp channels on a single 4-pin Euroblock connector, four (4) general purpose inputs and eight (8) general purpose outputs with +12 VDC and GND connections on a single 14-pin Euroblock connector, an RS232 on a 4-pin Euroblock connector, and two (2) RJ45 connectors for daisy-chainable Ethernet configured as Q-SYS Network ports: one (1) PoE port, RJ45 1000 Mbps only; one (1) Pass-thru port, RJ45 1000 Mbps only.

The peripheral shall feature multiple mounting options including a standard 19-inch rack or surfaces such as under-table or on-wall. It shall be one-half (1/2) rack space wide and less than one (1) rack unit tall (1.59 inches / 4.04 cm), allowing mounting alongside other half and quarter-rack width QSC Q-SYS QIO peripherals using an optional rack tray kit. The peripheral shall include two (2) reversible steel angle brackets for surface mounting.

The peripheral dimensions shall be 1.59" x 8.62" x 5.51" (4.04cm x 21.91cm x 14.00cm).

The peripheral shall be the QSC Q-SYS QIO-FLEX4A.
