In the 100V line speaker system, a transformer steps up the audio output signal voltage to 100V so that the output current for a given power is low. The resistance on long cables between the amplifier and loudspeakers will attenuate this low current signal much less than if the current were left at its normally high level.

Audio transformers should preferably use both high-permeability cores and the largest number of coil turns to create high primary inductance. The most commonly used audio transformer core materials are M6 steel (a steel alloy containing 6% silicon) and 49% nickel or 84% nickel (alloys containing 49% or 84% nickel plus iron and molybdenum).

Audio transformers must utilize both high-permeability cores and the largest practical number of coil turns to create high primary inductance. Coil inductance increases as the square of the number of turns and in direct proportion to the permeability of the core and can be approximated using the formula: L = 3.2 N28 ì A / 10 R

An Audio transformer with Step-up feature will step up the voltage or the current level to drive a load across it. Same happens for the Stepdown transformer too. It converts the voltage from higher to lower with the increased current output. The audio transformer also provides impedance matching specifications. When the output of one circuit or device is directly connected to the …

When constructed with windings on opposite sides of the core, the symmetrical construction helps to cancel stray magnetic fields as well. Although C-core audio transformers for tube amplifiers have had fairly wide acceptance (at least in Europe and Japan), C-core power transformers are not common in audio equipment.

Several valuable hints on the practical construction of transformers are also included for the assistance of the builder. A modulation transformer, like any audio power transformer, is designed to match the output impedance of one piece of equipment to an input impedance of a second piece of equipment.

At designing of audio electrical circuits the transformers are somehow overlooked because of their . complex problems in design and construction, relatively high price and bulky dimensions. However, sometimes . this is a pity because the transformers can increase the noise parameters of the circuit significantly which can
