The Soyuz 013 FET is a small diaphragm condenser microphone with cardioid polar pattern. The microphone has the ability to capture details accurately, making it suitable for recording pianos, guitars, choral ensembles, strings, orchestras and drum overheads. At the same time, this gives the microphone a warm sound characteristic. A recording of complex, transient instruments and sounds that fill the frequency spectrum and dynamic range pleasantly and warmly is given by the characteristic of soft highs and an accuracy in the midrange. With a limiting sound pressure level of 143 dB, the Soyuz 013 FET has a noise floor of 16 dB(A). A phantom power of 48V, which is transmitted through the XLR cable, is required for the power supply.
