Application field: PA Amplifier,Guita Amplifier, Stage Amplifier, Tube Amplifier,
Karaoke Amplifier
The transformer is widely use in the Stage amplifier, KTV, PA and other home theater amplifier. Amplifier requests the transformer is with high efficiency, small loss, Low interference resistance, small magnetic leakage, No static current sound, sufficient power for subwoofer, low temperature rise and other requirements. Toroidal transformer is the good choose for Amplifier. For Toroidal, the magnetic circuit closure is good and it can take full advantage of the magnetic properties of silicon steel, to reduce the magnetic leakage of the core.
