4 cable method - having trouble with volume and gain

Quad Cortex
1

4CM users, I need help! Do any of you have trouble with too much gain from your amp when using the QC as a multi-fx processor? I’m running mine through my Victory V40, and I’m struggling to get a completely clean sound for gigging levels. The V40 is a suuuuper clean amp, and I don’t ever have this issue with my regular old pedalboard in front of it. I’m using the 4 cable method in the QC manual - am I missing something? Seems really odd to me that the QC would push the preamp that much, even without any effects engaged, and also without adding any real volume to it.

The volume output on the QC is around 70 on the main volume btw. I would set it lower - but then the amp won’t be even close to being loud enough. My amp settings are 10-11 o’clock on the input gain and then I have to turn up the master pretty loud to get any usable volume.

Hey, to be clear–you are trying to use QC in the V40’s effects loop via 4CM, correct? Or are you trying to send the QC directly into the input of the amp?

I’m using the 4CM stated in the manual, so drives and comps go to the front while anything time based goes in the loop.

I have been using a 5150 for 4CM frequently without issue pretty much since the QC was released. Does the V40 use a parallel or serial FX loop? I ask as my early dual rectifier didn’t work that well for 4CM due to its parallel FX loop. Once I switched to a different amp with serial FX loop, everything worked and sounded like it should.

Note: I just read some info on the v40 which states it uses a lower impedance in the FX loop but it doesn’t say what that value is. Have you tried adjusting the QC impedance to find the sweet spot?

Did you ever get this solved? I had mine working, screaming loud - paths color coordinated… got to a gig yesterday and had 0 volume using 4CM - with everything cranked.

I did a factory reset, and still nothing.

My amp, when using an Eventide H9 in the effects loop for delay is super loud.

Something happening on the QC side for me.

Just to be sure are you using the master volume button to control all volumes?
Have you tried to disable it for the outputs 3/4? Then you can adjust this volume manually?

I tried this. It’s odd, and something had to have changed somewhere. In my IO settings, my out 3 gain is grey’d out and can’t be adjusted.

Out 4 is greyed out and you have it muted.

Hey there,
You have to disable the Master volume button to out 3/4 on system settings.

Hey @ameristos, just a follow up. Have you been able to solve this? Have you found where to change the settings for that output individually?

My issue was solved, yes. 1) I bought a second power supply and it didn’t deliver enough power. 2) i had a Cioks & Crux on my pedal board, and completely missed switching it to 12v on the Crux’s little dip switch.

Support also confirmed this can happen from an under powered supply… I sent them a report and my serial and they checked things on their end about my system.

I’m good to go, back with full volume. Thanks for checking back in

You are welcome!
So it was just a “underpower malfunction”, not a configuration issue.
