The Attero Tech by QSC unD4I-L is a four-channel Dante/AES67 audio interface that allows for integration of analog mic/line sources into networked AV systems like the Q-SYS Ecosystem. It features four balanced mic/line inputs, each with eight software-selectable gain presets and +48 V phantom power.
The 4 x 4 logic I/O (GPIO) offers an easy interface with microphone switches and indicator LEDs. Front panel indicators show each channel’s gain and phantom power status for easy troubleshooting. The unD4I-L also has two network connections to allow for daisy-chaining of one additional unD4I-L, and can be powered by either external +24 V DC or any PoE network switch.
