Talk:AV receiver

"AV receiver" is a quite poor title for this article....
"AV receiver" is a quite poor title for this article, and "Audio-Visual receiver is much better.


 * "AV receiver" could refer to something in cardiology referring to "Aurical/Ventrical - that is, to the upper two chambers of the mammalian or avian heart (Atrium (heart)) and its lower two, more powerful chambers (Ventricle (heart)).


 * "AV receiver" could also refer to something else in the circulatory system concerning "Arterial/Venous.


 * "AV receiver" could refer to "automatic video receiver"

There are probably other possibilities as well.98.67.108.198 (talk) 16:35, 5 September 2010 (UTC)


 * Agree and suggest that this article should be renamed, 'Audio Visual Receiver (AVR)'. This would cover both normally used terms, in my experience, for this unit. CPES (talk) 13:55, 26 October 2014 (UTC)

Too much technical detail
I have removed the text below because, while it's all good stuff, I suggest it's too technical and out of place on this Wiki page about AVRs.

'===Amplifier types=== Most receivers use class AB amplifiers, although class D amplifiers are becoming common. Class D amplifiers are more efficient and can be made smaller and lighter than an equivalent class AB amplifier. There are also other designs such as class G and class H. Class G and H are variations on the conventional class AB design. Class G has two sets of power supply rails. Normally the power amp is fed from the lower voltage supply. This helps keep power dissipation in the output transistors down. When the signal exceeds the lower supply voltage, the amp switches to the higher voltage supply so the signal can be reproduced without clipping. With a class H design, the supply rails are variable rather than two discrete steps. The signal actually modulates the supply voltage.'

'Usage' section ?
The purpose of the 'Usage' section, reproduced below, is not clear. As stated elsewhere in the article AVRs don't normally have radio receivers. The section lacks coherence and meaning and my feeling is that any relevant data should be extracted and put in the introduction and the rest be ditched. As a first move I suggest that the 'Usage' section simply be removed.

'==Usage==

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.

As home entertainment options expanded, so did the role of the receiver. The ability to handle a variety of digital audio signals was added. More amplifiers were added for surround-sound playback. Video switching was added to simplify changing from one device to another. Within the last few years, video processing has been added to many receivers.

The term audio/video receiver (AVR) or Home Theater Receiver is used to distinguish the multi-channel audio/video receiver (home theater receiver) from the simpler stereo receiver, though the primary function of both is amplification.'

AV receivers may also be known as digital audio-video receivers or digital media renderers.

The AV receiver is classified as an audio frequency electronic amplifier. But with the rapid addition of several features, AV receivers now generally have significant additional functionality.'

Mistake in "Amplifier power" section
The section describes a linear relation bewteen power and loudness (10 times more power to be perceived 2 times louder, that is l = .2*p) while calling it logarithmic. Either is incorrect. A1957 (talk) 21:29, 8 March 2023 (UTC)
