How to mix effects with all the inputs with aux send/return

Uh..Please elaborate on this! Do you seek instructions/descriptions of the various ways to operate aux and effect sends/returns on an analog console?

The following is clumsy: the signal produced by the mixer will usually be sent directly to an amplifier, unless that particular mixer is “powered” or it is being connected to powered speakers.

Functionally, the mixer output is always sent to an amplifier and the amplifier output to speakers. If the amplifier happens to be physically part of the mixer (a powered mixer) or the speakers (powered speakers) then so be it.

sugestion need terms defined

edit
I know this is not the cool thing to do, but I found alot of words with definitions at this link. check it out http://www.sweetwater.com/shop/studio/preamps/glossary.php. I know that you are not supposed to copy and paste so, I didn't but maybe some one with a little more time could take a look at this page and put the information into their own words. Note the term direct out, we have it listed here on Wikipedia but it is not defined.

Digital Mixing algorithms

edit

The audio mixing article says "Mixing - summing signals together, which is normally done by a dedicated summing amplifier or in the case of digital by a simple algorithm." (emphasis mine) Where is there information on such algorithms? (Hopefully I haven't missed it if it's already in this article!) There must be more complexity than simply summing, because (for example) summing more than one full-amplitude sine wave will result in a lot of clipping. Another example is a full-amplitude sine wave which, after a time, is joined by a second sine wave of equal amplitude -- how are they mixed without clipping, but preserving the psychoacoustic properties? I have yet to find a clear, non-code description of the details of this sort of thing. Or else I have a misunderstanding about the whole process. -- 98.221.23.155 (talk) 03:26, 8 March 2009 (UTC)Reply

As an end-user of digital mixers, I'm interested in your question, but I'm not a designer of digital audio. As far as I have been able to find out, well-engineered digital algorithms take into account how many signals are being summed, and each signal to be summed is reduced in amplitude by an amount which corresponds to how many active signals are present. Another scheme is to make the processing core be very high bit depth, much higher than the input or output resolution. Binksternet (talk) 03:15, 11 March 2009 (UTC)Reply
Digital summing is simple addition. To avoid clipping, the accumulator where result is stored typically has overflow bits. You have the same situation with analog summing with additional headroom in the summing amplifier. Avoiding clipping is a matter of managing the gain structure of the system. Responsibility for this is shared between equipment designer and equipment operator. ~Kvng (talk) 21:14, 24 December 2022 (UTC)Reply
