I/O-22
The Q-SYS I/O-22 is a sophisticated network device that provides microphone and line level inputs, line level outputs, and amplification services for a Q-SYS audio system. The I/O-22 is a network enabled, Power over Ethernet (PoE) device. The I/O-22 products are designed to connect to a Q-SYS system via Q-LAN to which the system Core Processor(s) is connected. The I/O-22 is an Input/Output device. Analog input sources can be connected to the I/O-22 and the analog audio is converted to digital audio and sent over the Q-LAN network to the Core for Processing. Likewise, digital audio can be sent from the Core over the Q-LAN network to the I/O-22 which converts the digital signal to analog for local use.
The I/O-22 has two General Purpose Input Output (GPIO) connectors providing digital input and output control signals. An RS-232 connector on the I/O-22 allows you to make a connection to the Serial Port and Control Script components in a Q-SYS design. When a connection is made, and an appropriate Lua script written, you can control and read from devices such as DVD players, recording hardware, video, lighting, and so on. The I/O-22 includes an amplifier that can power a small (4 or 8 ohms) local loudspeaker (not included).
