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 …
IMPEDANCE MATCHING IN AUDIO Myth or reality

Matching impedance is the key subject of this article. As it unfortunately happens, we all link our low impedance sources to our high impedance active amplification devices. There is no real choice here, since this is the way manufacturers build their machines: low output impedance for sources like CD,
How important is impedance matching in audio applications ...

This is known as BRIDGING. Bridging is the most common circuit configuration when connecting audio devices. With modern audio circuits, matching impedances can actually degrade audio performance. It's a common misconception. HyperPhysics used to show an 8 ohm amplifier output, but they've improved the page since.

It can mean "matching" an output impedance of one value or range, to an input impedance of a completely different value or range (this is also done in telephone circuits with a line-matching transformer). There are times and reasons to match I/O impedances in audio, and other times it is not desired.

The impedance (Z) matching device may be a component, circuit, or piece of equipment. Fig 8. An impedance-matching circuit or component makes the load match the generator impedance.

In audio input and output circuits the impedances are principally resistive to make interconnection easier — the impedance won't change too much over the range of audio frequencies. However, the impedance to radio frequency (RF) signals will often be very different to that at audio frequencies in order to keep RF interference out.
