In an effort to increase the flexibility of our entry-level models N100H and X100L, Aurender developed the UT100, a precision asynchronous USB Audio 2.0 to SPDIF (OPTICAL) converter. This accessory to our most affordable models is designed for customers who need to interface and adapt these Aurender models with only a USB output to products with a Toslink (optical) input. Applications include, when a DAC does not have a USB Audio 2.0 input or when a DAC requires a special driver for its USB Audio 2.0 input. Other applications for the UT100 include interfacing Aurender to the growing number of wireless loudspeaker systems. Custom installation components often only have a Toslink interface as well as high-end personal audio systems, A/V receivers and television sound bars.
