70V 100V 60W 4ohm Audio Transformer

Transformers do much more than just impedance matching. They can differentially balance a microphone or line-level signal at the source, and then de-balance the same signal at the destination (or more properly stated, the “load”). In the process, electromagnetic interference (EMI), the cause of all-too-familiar hum and buzz, is cancelled out as a function of the transformer’s common-mode rejection ratio (CMRR or CMR).

High-grade audio transformers, such as those manufactured by Lundahl in Sweden and Jensen in the U.S., exhibit high CMRR values across a broad spectrum of frequencies; low-grade transformers may help reduce hum and buzz a bit, but their CMRR is rarely sufficient to solve any significant problem. When it comes to hum and noise rejection, precision high-grade transformers are an invaluable insurance policy.

According to the usage and design,there are Ei19 Transformer,Ei28 Transformer,Ei35 Transformer,Ei48 Transformer,Ei57 Transformer,Ei66 Transformer,Ei76 Transformer,EI 86 Transformer,EI 96 Transformer etc series.
