EQ suggestions for Helix and Live FOH sound

Recommended Posts

I know every venue/speaker system has its own unique requirements but I was wondering if anyone had personal experience/suggestions or some good resources they could recommend for EQing both the Helix and possibly the FOH speaker mix for use with a helix in a live 6 piece band setting. 

 

One issue I am addressing  is the "harshness" of the sound as the volume increases. However, I don't want to lose that tactile "sizzle" feeling the guitar tone has!

 

For reference I am looking at mostly hard rock / heavy metal / jazz / funk 

using FOH/monitors in the JBL EON 7xx line.

Hi,

 

I personaly use global EQ on the XLR Out only which I send to FOH.

 

Doing this allow me to not constantly touch my presets and keep the same sound, and just ajust if necessary what I send to FOH for the sound guy

Helix allows you to add Global EQ to 1/4", XLR or both outputs.  When building presets, forget that Global EQ exists.  Make it sound good coming out of mixing monitors. 

 

An intended way to use your modeller is to send XLR L/R to FOH, and use 1/4" for stage volume, to be able to hear yourself.  Or use in-ears.  In order to hear themselves on stage, many people use an FRFR, a power amp + cab, or go into an effects loop of an amp + cab.  In all 3 cases (with some exceptions), there is no way to adjust your EQ. 

 

 

So.

 

If you go direct to FOH, then:

Global EQ is meant to be able to adjust your on-stage sound and nothing else.  Sometimes you go to play a show and the stage is super-resonant, and it keeps rattling when you play a certain note or chord.  Or the stage is surrounded by ceramic tile, and your ears are hurting because everything is loud and shrill.  Global EQ to the rescue!  Unlike your typical amp high/mid/low, Global EQ is extremely flexible. 

 

When I toured, I mostly left the Global EQ off for the on-stage amp.  However, since the clubs I played were not all huge, sometimes the on-stage sound would interfere with the overall mix.  That's when the sound guy would ask me to adjust my sound a certain way.  Or sometimes, the stage is too boomy, and I would have to make the adjustment myself so I would not sound like one of those cars with a giant subwoofer in the trunk! 

 

 

In summary:

Leave the direct FOH mix to the sound guy.  Don't add any Global EQ to the XLR outs.  Sound guys can apply whatever EQ they want to what you are sending them.  Use Global EQ to compensate for the unforeseen stage acoustics.  And nothing else. 

 

Every room is different.  Even if you play with the same exact lineup, same exact club, same exact sound guy several days in a row, the room may sound different on any day due to: humidity, temperature, number of people, where people are, how worn out your strings are.

Hm, but the sound folks have better EQs themselves and actual control of the FOH sound.

That's exactly what I'd recommend as well.

Aside from Global EQ you can most likely get the appropriate level of "sizzle" by simply using the new Helix cabs with the appropriate mic and positioning parameters much more precisely than doing it artificially through EQ.  My presets seem to sound pretty close to the same played through our stage monitors (Yamaha DXR 12) and our front end speakers (QSC KLA 12).  Using the right cab setups with the new cabs and I only need to make very small minor EQ adjustments with a final parametric EQ at the top end and everything's fine regardless of the volume.

 

Making room adjustments is a different animal and there are specific automated tools on modern mixing boards that allow for such things using white noise generators.
