So my set up is guitar into the quad cortex, TRS cable through output 3/4 into a electrovoice ZLX 15P G2. I mention this specifically because someone might have experience with this model. But in general I think this would apply to any powered PA with DSP modes to be a do it all powered speaker.
So I have the option of flat frequency response on both the input as well as and mode in the main output section of the unit to select it for flat frequency response.
But here is the catch. From all my research the quad cortex is considered a line level device. And on the input section there is also an option for line input. There is more low end when set to Flat.
Im just trying to know what the most accurate way to do this would be. I know its kinda a trust your ears thing and do what sounds best. But I kinda want to set up the PA the way you would if it was just a plug straight in FRFR cab to get the truest sound of the quad and then adjust the levels of all my presets so I dont have to touch anything but the main volume on the quad to get the overall loudness I want.
I think what is frustrating me is that all of the different modes these things have change the way they behave and sound. But I use it as a monitor so the position setting i have as a floor monitor. That just makes sense. But its really the input setting that is getting me mixed up.
So if it was you, would you choose a FLAT input setting or a LINE input setting. And im told it is still ok to run a TRS cable even if your are running it mono to a single source. If that is incorrect please scold with fire in the comments.
A flat / colored (not flat) frequency response normally is in no way related the signal level (mic, instrument, line). So I’m kinda confused by your question.
There’s probably a pad on the input if you run it at line level. It’s possible you’re hearing a volume difference between flat and line level which is why there’s more bass response. Just go with whichever sounds best. All of the FRFR/PA speakers sound a little different than each other so you gotta just go with what sounds good for your setup. They aren’t ever going to be absolutely flat in response (studio monitors are supposed to be flat but they rarely ever are, especially depending on the room).
Something people never realize is that an FRFR isn’t always the best option for live. It sounds very different than an actual cab. It’s basically like having a studio monitor on stage with an iso cab. No one is used to hearing that come from a cab on stage, and people are always confused why it feels different to them than if they had a real amp. Just hearing an amp in a room with no microphone, etc is very different. Many mid size clubs are just using a miced signal to fill out the amp sound at a venue, which isn’t just the sound of a miced up cab. FRFR is basically a glorified studio monitor

Yeah I ended up doing exactly that. I just had this moment where im like, "im overthinking this. If it sounds good who cares what the actual setting is. Whatever sounds best in the situation is the proper setting is how I look at it. Plus its not like im using an actual amplifier. I gotta remember im breaking every rule in the tube amp bible so why cant I deprogram my brain from feeling boxed in as if I was using an actual amp set up. I forget that my amps always had to be adjusted for different room sizes. There was not set and forget it ever. But thanks for your response. It helps me feel better about just trusting my ears.
