The Audio Transformer works at frequencies between 20 Hz to 20 kHz. So, the operation of an Audio transformer has much wider frequency range. Although an Audio transformer does not have a physical connection between his primary and secondary coil, the transformer provide bidirectional feature between this two windings. We can also use the same primary side as secondary and secondary as primary. In such case, the transformer provides signal loss in one direction and signal gain in reverse direction or vice versa. As discussed above, the audio transformer uses Impedance balancing technique. It is very useful for balancing amplifiers and loads (Loudspeaker and other) that use a different input or output impedances for maximum power transfer application.
According to the usage and design,there are EI19 transformer,Ei28 Transformer,Ei35 Transformer,Ei48 Transformer,EI57 transformer,EI66 transformer,EI76 transformer,EI86 transformer,EI96 transformer etc series.
Our Factory also provide OEM Audio Line Transformer service,it can be made to meet customer product features and quality requirements.
