Audio Transformers

Our company's audio transformer fit a large variety of of audio designs and requirements, they can operate over a broad band of frequencies via electromagnetic induction. They are capable of performing muitiple operations such as carrying D.C. in one or more windings, transforming voltage and current to the required level, acting as an impedence matching or coupling device or as a kind of filter, allowing passage of only a limited range of frequencies.

Here we introduce some of our standard models which are being widely used as a impedence matching transformers in the some typical applications such as 25V lines to voice coils and 70 volt line to voice coil
