Connections with Helix

[OrangeBlackstar]

Hello all, 

 

I'm currently planning to upgrade my rig to include a helix, and have come across the following question: why does everyone connect the helix to an external audio interface with XLR cables? I currently have an HX stomp and I connect it to my scarlet solo with a TRS cable. From what I've gathered, XLR cables are popular because they're balanced signals... but so are TRS cables. However, almost every review I've seen of the helix involves the player hooking it up with two XLR cables to their external interface. 

 

I plan on upgrading to the 2i2 interface for multiple inputs, that way i can have a stereo sound. However, I'm unsure of if I should connect the Helix to the 2i2 with TRS cables or XLR cables. Which makes more sense?

 

The 2i2 has an option for phantom power. From the research I've conducted so far, phantom power can potentially be harmful to a TRS cable (and as a result whatever else is connected to it) if plugged in. If I use XLR cables, it appears as if phantom power won't be harmful in any scenario; that being said, do I need phantom power on? Or do i just record with it off? 

 

Lastly, since I currently use the HX stomp as my amp, I always have the output set to line level. Is this something that will be the same with XLR cables, or will I need to change my output to instrument?

 

I know these are fairly basic questions but I couldn't find answers pertaining to this anywhere else. Any and all input is appreciated.

Short cable runs (<20Ft) there's little difference between 1/4" TRS and XLR. Longer runs there's less chance of noise with XLR.

If you standardize on XLR for connections to FOH/AI, the 1/4" outs are available for connection to stage monitors/guitar amps etc. You have a Stomp, so it's not an option.

 

Mic level is what most FOH engineers want to see. If your AI is overloading at line level switch to Mic level. If the signal to your AI is weak, switch to line. It's all about gain staging.

 

I always connect from my Helix Floor to my Scarlett 18i20 with XLR cables, with the level set to Mic. Works for me, no changes required when I play out with FOH support, and I use 4cm with my tube amp on stage.

 

Phantom power is intended for use with microphones that need to be powered (condenser mics). IIRC, prior to the Stomp, using a Helix with Phantom power turned on introduced noise. As I understand it, the Stomp doesn't have that problem.
