Whirlwind Little IMP Impedance Transformer designed to match low-impedance microphones to high-impedance inputs. This compact inline adapter features a female XLR input and a 1/4 inch TS male output plug, making it an essential tool for connecting professional mics to guitar amps, mixers, or audio interfaces that lack XLR inputs. The rugged metal construction ensures durability for stage and studio use, while the internal transformer provides clean signal conversion from Low Z to High Z. Note that there is some visible oxidation/discoloration on the 1/4 inch tip as shown in photos.
