On the other hand, transformers as coupling devices add about 80 Ohms across the whole audio band, because this is the sum of their windings DC resistances. Thus, in some environments where the lowest possible output impedance is needed, a direct or capacitors coupling can be preferred.

audio coupling transformers is a practi- cal proposition, and with care and a bit of patience, not difficult. First though, we should look at some background to the history and basic theory of audio trans- formers. A long history The first audio transformers, known as 'induction coils', were produced more than a century ago to match the low im ...

Sean Gold, William Jett, in Analog Circuit Design, Volume Three, 2015. Driving transformer-coupled loads. Transformer coupling is frequently used to step up transmission line signals. Voltage signals amplified in this way are not constrained by local supply voltages, so the amplifier’s rated current rather than its voltage swing usually limits the power delivered to the …

Toroidal transformers are better in this respect, but that's an expensive way to get a signal transformer that will be far bigger than an equivalent 'audio transformer'. Of course, transformers are used in valve (vacuum tube) amplifiers, occasionally for inter-stage (coupling) but almost always for the speaker output.

In this technique, the coupling can be done by using transformers. So looks bulky and expensive for audio frequencies. There will be frequency distortions in the speech signal, audio signal, music, etc. The transformer coupled amplifier gives high gain and amplifies the input signal.
