Amber i1 is the entry point into ESI's new line of professional USB audio hardware: the Amber series. As the successor to the legendary U22 XT, this audio interface offers much more than other products in this price range. The Amber series features a new, modern, and eye-catching design with an amber-colored volume knob that stands out against the sand green main color of the housing. Hardware loopback, USB-C, a completely redesigned LED display area, separate line inputs, signal source selector switch, and exceptional audio quality in its class are just a few of the reasons to choose Amber i1.
