Shure A15BT Bridging Transformer
An in-line bridging transformer, the Shure A15BT matches, bridges, or isolates balanced and unbalanced devices that run at different impedances and levels.
Its XLR female end is 33,000 ohms and its XLR male end is 7,500 ohms as supplied, and the male end converts to 600 ohms with an internal lead change. Either end can be unbalanced by joining pins 1 and 3.
A typical use is bridging a 600 ohm line output into a high-impedance aux input. The A15BT also matches a high-impedance mic to a recorder’s medium-impedance input and gives a device with only an aux output a balanced 600 ohm line output.
