The term receiver basically refers to an
amplifier that has a built-in radio tuner. With
A/V receivers the basic functionality is to
receive an audio signal, amplify the audio
signal, and allow pass-through of the
corresponding video signal to a display device
such as a projector or a television.

popular songs into a microphone over
prerecorded music,

An audio power amplifier (or power amp) is an
electronic amplifier that amplifies low-power
electronic audio signals (signals composed
primarily of frequencies between 20 - 20 000
Hz, the human range of hearing) to a level that
is strong enough for driving loudspeakers and
making the signal–whether it is recorded
music or a live speech–audible to listeners.
70/100V AMP

In a constant-voltage speaker system the
amplifier uses a transformer to step up the
voltage of the audio signal to reduce power
loss over the speaker cable, allowing more
power to be transmitted over a given wire
diameter. Each speaker in the system has a
step-down transformer to convert the voltage
back to a usable level.

In Canada and the US, they are most
commonly referred to as 70-volt speakers. In
Europe, the 100V system is the most
widespread, with amplifier and speaker
products being simply labeled with 100V.
