The Ultra-HDDA (High-Definition Discrete Architecture) mic preamps used on the US-HR series feature a discrete construction. They have a higher number of components and are far away from mass-produced preamps. Their EIN (equivalent input noise) rating, which measures the absence of noise, is truly low for the US-2x2HR and US-4x4HR. Combined with a newly improved audio circuit and support for sampling rates up to 192 kHz, our in-house developed microphone preamplifier delivers enhanced audio performance with the most transparent and low-noise sound, reflected in a signal-to-noise ratio of 110 dB.

Ultra-low-noise mic preamps achieve -128 dBu EIN (Equivalent Input Noise)
XLR/TRS jacks allow the input of condenser mics and the balanced connection of synthesizers and other equipment
Wide gain range ensures sufficient level even with dynamic microphones
Guitars can be directly connected enabling the use of 3rd-party plug-in effects

Usability is key
All US-HR models offer a unique dye-cast aluminum honeycomb structure on the side panels with a slight upward tilt. This design not only results in a sleek, eye-catching design, it also provides just the right amount of weight so the interface won't move when cables are connected or disconnected. Equally important, the upward tilt offers the ergonomic benefit of being angled in such a way as to make the interface easy to work with.

With four microphone preamps for multi-mic setups, four configurable balanced outputs, superb sound quality and easy operation, the US-4x4HR is the ideal choice for the demanding musician, producer or home-recordist requiring more than two audio channels.
