The Fat Top II Active/Passive is a short ribbon microphone that delivers a warm, rich, fat, rounded tone. The bi-directional polar pattern picks up sound essentially equally from both faces with a large null between faces ideal for isolating sound sources. This microphone is fitted with an active/passive switch. When switched to active mode it isolates the output of the ribbon from the microphone preamp, the ribbon is consistently loaded at an optimal value. The active mode requires phantom power and will add up to 20db of gain. Best suited for guitar cabinets, piano, brass and percussion instruments. Can be used in pairs in a Blumlein set up to pick up the entire room. Fat Top II Active/Passive comes standard fitted with the upgraded Lundahl LL2913 transformer. Introducing the upgraded Lundahl to the already quality hardware makes for an extended frequency range. This gives the mic improved definition, lower floor and higher ceiling.

Sequential serial numbers are not an indication of a matched pair. Stereo pairs are built and assembled by our technicians. The exterior sleeve put on the microphone for serial number tracking does not indicate if they are a matched pair. If you would like to special request the serial numbers to be sequential, please be sure to add that to your notes on the checkout option.
