Output Transformer
A transformer is known as a device that transfers electrical energy from one circuit to another through inductively attached electrical conductors. A transformer that matches power output of an amplifier to impedance of a load is called output transformer. A varying current in the first circuit creates an altering magnetic field. The changing magnetic field induces a changing voltage in the second circuit. This effect is known as mutual induction.
When the load is coupled to the secondary circuit, electric charge will flow in the secondary winding of the transformer and transfer energy from the primary circuit to the load joined in the secondary circuit. The most significant application of a transformer is to enhance voltage before transmitting electrical energy over long distances through wires.
Since wires possess resistance they disperse electrical energy at a rate proportional to the square of the current through the wire. By changing electrical power into high voltage form for transmission and back again later on, they enable economic transmission of power over long distances. Through decades transformers have shaped the electrical supply industry, allowing generation to be located distantly from the point of demand.
In addition, they are also used widely in electronic products to step down the supply voltage to a suitable level for the low voltage circuits possessed by them. The transformers electrically segregate the end user from contact with the supply voltage.
When replacing the audio output transformer on a radio, the replacement should match the impedance of the original as close as possible. If the wrong transformer is used, the results can be low output and loss of tone quality. Universal output transformers are available which have multi-tapped primary and secondary windings to match a wide impedance range.
While replacing any output transformer ensure the replacement should match the impedance of the genuine one. The wrong choice of transformer may result in low output and loss of tone quality. There are vast range of output transformers available online that have multi-tapped primary and secondary windings to match a wide impedance range.
About the Author
High Voltage Transformer - Amp-Line Corp. manufactures general & special purpose power amplifiers and power sources in audio frequency and ultra-sound frequency (RF) ranges. These products include constant current sources, constant voltage sources, frequency converters and plasma power supplies.
does the brand of the amplifier have to match the brand of the sub woofers?
Not at all. The most important part is finding an amp that matches the RMS rating at your final ohm load.
There are companies that make amps that fall in line with their subs. Meaning, that a certain line of subs will easily match up with a certain line of their amps. Kicker is a good example of this.
