The Symetrix SymNet xIn 12 is a Dante-enabled audio input expander designed to seamlessly integrate with SymNet DSP processors, providing additional analog audio inputs over a Dante network. This unit extends the input capacity of a SymNet system by offering twelve channels of high-quality analog-to-digital conversion, which are then transmitted as digital audio streams via a standard Gigabit Ethernet connection using Audinate's Dante protocol. Each channel is equipped with a combo XLR/TRS input that accepts both microphone and line-level signals, complete with phantom power, making it versatile for connecting a variety of sources such as microphones, instruments, or playback devices. The xIn 12 is part of Symetrix's modular approach to system design, allowing integrators to scale their audio input requirements precisely by adding expanders as needed, without being constrained by the fixed I/O of a central processor.

The device is engineered for reliability in professional installed sound environments, including corporate AV systems, houses of worship, performance venues, and broadcast facilities. It features high-performance converters with low noise and distortion, ensuring pristine audio quality from the point of analog capture. Configuration and control are managed entirely through the SymNet Composer software, where the xIn 12 appears as a networked audio device. Within the software, integrators can assign Dante channels, adjust input gain, apply phantom power, and set up basic processing like high-pass filters before the audio is routed to the SymNet DSP for more complex mixing, dynamics, and effects processing. This centralized software control simplifies system design and deployment.

Housed in a compact, half-rack-width metal enclosure, the xIn 12 can be discreetly mounted in equipment racks or near source locations. It is typically powered via an external AC adapter. By leveraging the Dante network for both audio and control data, the SymNet xIn 12 reduces cabling complexity compared to traditional analog multi-core snakes, as all audio from multiple expanders and the main DSP can travel over a single Ethernet cable. This creates a flexible, distributed audio system where I/O can be placed exactly where it is needed throughout a facility, all while being managed from a single software interface, representing a modern and efficient solution for expanding professional audio system inputs.
