All of our rotary DJ mixers are fully engineered and hand built to order from our studio in Berlin. For the highest sound quality, we have developed our own discrete Class-A amplifier, used from the phono inputs all the way through to the balanced outputs. As such, all circuits in the mixer remain in Class-A at all times. After trying many brands from all parts of the world, we have selected only the highest quality components - for long life as well as tone. With all potentiometers being made by Alps in Japan as well as our in-house developed audiophile grade linear power supply, we have achieved absolute purity of sound. Two stages and fully discrete Class-A Resør Phono MM preamplifiers packed with features designed specifically for the vinyl. With tremendous analog warmth and headroom, punchy low end bass, transparent mids and free and open high frequencies, our mixers offer a completely unique palette for you to work with.
