Talk:Line level

message: We should clarify that it's not necessarily a difference in level, but a difference in impedances and the amount of power that can be sourced by an output.  Line level outputs are not meant to drive loads like headphones. — Omegatron 22:43, 21 November 2006 (UTC)

message: The end of the Overview section currently states that the line level output strength on a device is not affected by the source volume setting.  Does this need clarification/removal?  Almost all of my pro audio equipment which uses line level outputs has a master volume knob which affects the sound leaving the line level output.  Does it just refer to the general line strength or something? Lexusperplexus (talk) 14:34, 16 March 2011 (UTC)
thread_title:  Section: Overview 

message: I just finished changing all the units in the article. I had looked here in the talk page beforehand, but neglected to flip through the history, which revealed a number of other editors having changed the units in various ways.
To explain my changes, I tried to make the words uniform (i.e. if it says 1 kX for one thing, it shouldn't say 1000 X for another), and beyond that, merely be as faithful as possible to the house style for units (spell out the word of a unit once, use its correct abbreviation thereafter, use a non-breaking space before the unit, uniform significant digits, etc). The WP guidelines are fairly scattered through the help, but a few of the changes are clumped nearby in WP: 'unit' style (and its surrounding sections and pages).
I think having this article's numbers and units clear, correctly wikilinked, and uniform in style is very important to the article's integrity. If there are objections to anything I've done, let's please discuss it! —Joel D. Reid 06:17, 30 May 2007 (UTC)

message: I removed both references to manualshark.org's PDF file (used to 'source' the colors used for line in and line out).
The whole PDF is wholly black and white and doesn't make any mention of colors except for microphone in being 'blue' --not light blue mind you-- which still contradicts PC_System_Design_Guide#Color-coding_scheme_for_connectors_and_ports (mic in is not a line in).

message: The article mentions that pro lines are usually differential and then it says that the level is x dbu... OK. So are you measuring each phase with respect to ground or a load placed between the two phases? I tried to find this information elsewhere but I haven't yet succeeded.  — Preceding unsigned comment added by 108.28.74.221 (talk) 16:01, 20 March 2013 (UTC)

thread_title:  voltage on differential lines. 

message: If 1.736 volts is "approximate", why is it given as four significant figures, down to millivolt precision? 24.85.131.247 (talk) 05:35, 3 August 2013 (UTC)
replies: text: Agreed. On the face of it either the "approximate" heading, or the figures under it, look silly. Jeh (talk) 00:54, 7 September 2013 (UTC)

thread_title:  Nominal Levels: Approximate? 

message: The section on the line out input states: "The signal out or line out remains at a constant level, regardless of the current setting of the volume control." This may be true for professional audio, or other equipment, but on PC's (which is the experience that the vast majority of the public will have with "line out"), this is clearly untrue. Maybe its incorrectly used, but those symbols, and the term "line out", refer to an output on the PC that speakers are connected to, which is very much controllable volumewise. Again, this may be misusing the term, but since everyone (or at least, that vast majority of the public) does it, surely that should be mentioned in the article?

replies: text: . Okay, I fixed those bits through simple deletion. There are many configurations of volume, and such global statements as you identified. cannot always be true. Thanks for the note! Binksternet (talk) 04:39, 8 December 2013 (UTC)
replies: text: Very old discussion as this is, it seems this related to consumer equipment with built in amplification (like an all in one stereo system, boombox etc) with the Volume control for the integral amplifier, in which the line outs are not controlled by that Volume control. 82.71.30.178 (talk) 20:26, 24 June 2020 (UTC)
