Matching Amplifier to Loudspeaker The maximum power transferfrom an active device like an amplifier to an external device like a speaker occurs when the impedanceof the external device matches that of the source. That optimum power is 50% of the total power when the impedance of the amplifier is matched to that of the speaker.

Audio Level & Impedance Matching Transformers create compatible signals between microphones, line-level devices, laptops, digital 75 ohm and 110 ohm AES/EBU devices. For example, Audio Level Matchers allow you to connect a professional studio microphone to a computer or other "consumer" style recording device.

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.

Impedance matching in audio equipment means that the output impedance from one device must be the same as the input impedance of the device that is connecting to. This ensures a good signal transfer between devices. Think of kids on a playground. When everybody gets along, things run smoothly.

If the speaker cable characteristic impedance closely matches the impedance of the loudspeaker, these resonances can be absorbed by the resistance of the speaker. In order for this to happen, however, the speaker impedance must be purely resistive and equal the cable Z 0 at high frequencies. Very few speakers have this characteristic.
