The main difference comes in to play when using phantom power on a mic input. XLR keeps it’s pins isolated from each other and TRS will short the ring and the sleeve as it’s plugged in. There’s no difference as far as outputs go. > [@XLR vs TRS output](https://unity.neuraldsp.com/t/xlr-vs-trs-output/7903/2): > > Both are balanced connections and are basically the same as far as signal flow goes.

Hello all I’m buying a quad cortex wanted to ask one question can TRS cables also can fit the quad cortex ---

Are the TRS cables for the inputs, effects loops, or outputs? Any description of the intended use would be helpful. You can definitely use TRS cables for the expression inputs. ---

I don’t mean to sound condescending, but TRS cables are definitely talked about in the QC manual. Ctrl + F and you’ll find what info you’re looking for. ---

Response from Neural: Hey Stephen, Appreciate your reply and clarification. We’ve double checked this with the hardware engineers and it appears there is indeed a typo in the Quad Cortex manual. It should read the following and we’ll update it ASAP - **INPUTS 1/2** - CONNECTOR: (2) XLR-F + ¼ “ **TS/TRS-F** (GROUND LIFT) - XLR IMPEDANCE: **3.8KΩ** - **TS/TRS** IMPEDANCE: 10KΩ - 10MΩ - MAX INPUT GAIN: +60dB So yes, the combo inputs 1/2 on Quad Cortex accept TRS balanced connections. Let us know if you have further queries or concerns. Best regards, Neural DSP Support Team
