MANLEY is a premium American audio manufacturer that has been around since the late 1980's. First known for its high-end vacuum tube audiophile power amps and preamps, Manley went on to lead the tube renaissance in the pro audio world, launching now-legendary products such as the Reference Cardioid Microphone, Variable Mu Stereo Limiter Compressor, the Massive Passive Stereo Equalizer and the VOXBOX. In recent years, having modernized production techniques at its California factory, Manley is creating a whole new crop of affordable future-classics such as the CORE Reference Channel Strip, the FORCE 4-Channel Mic pre, the ELOP+ Stereo Limiter Compressor, and Nu Mu Stereo Limiter Compressor. Designed to impress. Built to endure. All Manley gear is proudly manufactured in the USA.
