which cable?
which cable do i use from my aer/3 line out to a qsc powered speaker? is a 1/4 instrument cable sufficient or do i need a speaker cable? the xlr di out from the aer won't transfer the effects from aer.

A balanced TRS to balanced XLR may also work. Dunno. Last edited by sdelsolray; 10-16-2018 at 09:36 AM.

You need a speaker cable, with two insulated leads to carry a high power audio signal. An instrument cable has just a single lead and shield, sufficient for a low millivolt pickup signal only.

I think you will find this video explanation helpful:

All the info I could find suggests that the 1/4" line output is TS. As sdelsolray suggests, a TS to XLR cable will work, here are Sweetwater's choices: https://www.sweetwater.com/shop/cables/finder.php

You may find it noisy with an inst cable .
watch the video. it explains it pretty well. What you ideally want going to the qsc is a balanced signal, one where there are two signals 180 out of phase with each other and ground. all the aer sends is an unbalanced . So you may try a di box with an xlr out to the speaker. Page 9 under outputs in the manual says the line out is a preamped mono 1/4 . Which tells me it's TS (stereo =TRS) designed to go to another amp. it says the preamp signal is 1.4 v . I would try a di box.. here's another good video. https://m.youtube.com/watch?v=g7Pd6NdgX80 Last edited by varmonter; 10-16-2018 at 08:55 AM.

Sometimes, use of a TRS cable jack into a TS output jack will cause the signal to appear on both the tip and the ring as it is being transmitted to the balanced XLRF input of the powered speaker. If that happens, the cable will not work properly. This does not happen often, but it can occur. So a TRS to XLRM cable is likely to work, but only if the signal from the amp is carried only by the tip of the TRS cable.

First up: try a plain old TS cable, like a regular guitar cable. You should be able to go right from the line out on the amp into one of the combo jacks on the speaker. Make sure the input is set to "Line" not "mic" level. If using that over whatever distance you need isn't too noisy, you're fine. If it is noisy, then run a much shorter TS cable from the amp's line out into a simple DI box, and then run an XLR cable from the box to the speaker (this time with the input set to "Mic" level). That will give you the balanced connection you want and can't get with the effects from the AER. Louis
