J30A11C microphone transformers from OEP are ideal for signal splitting and impedance matching. These audio transformers are fitted with an electrostatic screen and stray flux copper band. They are encapsulated in a mumetal screening can that reduces electrical noise by up to 30 dB and ensures low distortion. With drive up to +10 dBU these microphone transformers are a high performance solution.
