Impedance Matching. In the early days of high fidelity music systems, it was crucial to pay attention to the impedance matching of devices since loudspeakers were driven by output transformers and the input power of microphones to preamps was something that had to be optimized. The integrated solid state circuits of modern amplifiers have largely removed that …
How important is impedance matching in audio applications ...

Impedance matching is not used in modern audio electronics. A mic output might be around 600 Ω, while mic preamp inputs are 1 kΩ or more. A line output will be something like 100 Ω, while a line input is more like 10 kΩ. A loudspeaker amplifier will be less than 0.5 Ω, while loudspeakers are more like 4 Ω.

The impedance matching in amplifiers helps reduce losses and transfer maximum power from the input side to the load through n amplifier stages. Impedance Matching in Amplifiers In a two-stage amplifier, the output impedance of the first amplifier stage forms the input impedance of the second stage amplifier, and the same pattern is followed in a multi-stage amplifier until the …

Impedance matching of inputs and outputs is necessary because the gain of a single amplifier is often insufficient for a given purpose. For this reason several stages of amplification are used, which involves feeding the output of one amplifier into the input of another.
Mix and match impedance – PS Audio

January 21, 2018. Popular audiophile lore has it that a mismatch in impedance between the preamp and amplifier will result in bass loss. Yup. If the amp’s input impedance is too low weaker bass will be the result. That’s true in the same way it’s important to pump the car’s accelerator before starting it.
