UC1 “Universal Converter”

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 is a mid price USB interface and monitor controller that has a different approach. It is an ideal match with the Grimm Audio LS1 or PMC monitoring systems, and works great with other active loudspeakers too.

“The ‘Universal Converter’ UC1 solves all your monitoring needs. It has outputs for analog and digital

destinations and offers analog and digital loops with LS1 quality converters.”

Present day use cases have been the premier focus from the first UC1 sketches onwards. This led to an unusual design with remarkable flexibility.

When mixing and mastering, not all inputs and outputs are equal. The UC1 offers 18 channels of USB I/O of which some are dedicated to monitoring and others to re-recording. With the second USB ‘i-put’ on the front there is no sample rate and word length restriction when using your iPad or iPhone. The i-put also serves as a convenient stereo USB input for laptops.

Engineered with audiophile-grade components — premium drivers, hand-matched crossovers, and a hardwood enclosure tuned for natural decay. Every cabinet is internally braced and damped to suppress resonance below the threshold of audibility.

• Custom 6.5" mid-bass driver with paper-pulp cone for transient accuracy.
• Soft-dome silk tweeter with neodymium motor for airy, fatigue-free highs.
• Point-to-point hand-wired crossover using silver-foil capacitors.
• Bi-wirable terminals plated in pure copper.

Place each speaker on its dedicated stand, toed-in toward the listening position. The hardwood enclosure resonates in concert with the drivers — a deliberate, musical interaction rather than a flaw to be eliminated.

Connect to a quality amplifier using bi-wired speaker cable for the most transparent presentation. Allow 50–100 hours of break-in for the drivers and crossover capacitors to settle into their final voicing.
