Pro consoles use XLRs for lline out to power amps and active speakers. I'd guess that the XLR input on that amp is line level. The XLR output may be line level or higher - the manual should provide the details. | |

| Oct 20, 2018 at 18:43 | comment | added | LorenzoDonati4Ukraine-OnStrike | OK. Try to do that when you can. It will help us a lot. | |
| Oct 20, 2018 at 18:30 | comment | added | user1245 | @LorenzoDonati I could but right now Im not at that place. I can access on Monday. | |
| Oct 20, 2018 at 18:29 | comment | added | LorenzoDonati4Ukraine-OnStrike | Can't you shoot a photo of the real thing? Haven't you access to the amplifier you describe? BTW, linking to external images is frowned upon here, since the links may rot and it involves extra steps and maybe access to cloud-based sites. The question should stand on its own feet as much as possible. | |

| Oct 20, 2018 at 18:07 | comment | added | LorenzoDonati4Ukraine-OnStrike | If you posted some more photos (entire amp; front panel; entire back panel with any data label) we could have more info to help you out. | |
| Oct 20, 2018 at 18:07 | comment | added | user1245 | Im not sure I saw it can take like 2V. | |
| Oct 20, 2018 at 18:04 | comment | added | Passerby | I'm guessing here, but balanced audio is typically mic level voltage. | |
| Oct 20, 2018 at 18:00 | comment | added | user1245 | @Passerby Can be but I don’t know. Can we find the voltage levels for these inputs? | |
| Oct 20, 2018 at 17:55 | comment | added | Passerby | Isnt that another way to say differential or balanced? Those are xlr differential connectors | |
| Oct 20, 2018 at 17:46 | comment | added | user1245 | Does that lift break the safety earth you mean? | |
| Oct 20, 2018 at 17:35 | comment | added | TimWescott | Symmetric and asymmetric. Ground lift disconnects the ground pins on the input connectors from the amplifier's local ground, to reduce problems with ground loops in large venues. | |
