There are many USB audio interfaces on the market but few of them are designed with both the sound quality and the specific use case in mind. The Grimm Audio UC1 has a different approach: it is a USB interface and monitor controller in one. The UC1 is an ideal match with the Grimm Audio LS1 or PMC digital monitoring systems, but it works great with analog (active or passive) loudspeakers too. Add a pair of secondary loudspeakers and headphones, and all your monitoring needs are covered with the flip of a switch. The Universal Converter UC1 solves all your monitoring needs. It has outputs for analog and digital destinations and offers analog and digital loops with reference quality converters.
