The Pharos RIO A (Remote Input Output Audio) device provides a convenient and scalable way to add audio integration to your Pharos system. The RIO A has an audio input, supporting linear timecode or up to 30 band spectrum analysis, as well as a MIDI input and output. Each device can be placed where it is needed and connected to the Controllers over an Ethernet network.

The RIO A is Power-over-Ethernet (PoE) powered, with a rugged DIN-rail mounting enclosure and install-friendly connectors. The stereo balanced line level audio input supports auto or manual gain (adjustable in software). The spectrum analysis is configurable from 3 to 30 bands on each channel, and triggers can be set on either instantaneous or peak level. The audio input can also be configured to receive linear timecode on either channel.

Remote Devices allow the fully scalable Pharos system to be tailored to the needs of each individual project. Multiple Pharos Controllers can be used together with up to 200 Remote Devices and will synchronise automatically. The Controllers are programmed using the free Pharos Designer 2 software.
