Sweet Spot for a keyboard channel on a Mixer

[Linson]

Hi Friends,
Can someone share some insights on what would be a desired EQ settings ( High , Mid, Low ) for a Mixer channels for a PSR keyboard connected to (stereo ( L & R  ) . I am looking for some general settings ( as a starting point ) however we have a Allen & Heath ZED-16FX Mixer and 15 inch DSR Yamaha Speakers. Environment will be just Keyboard and singing only in a Church hall ( 500 people ). if anyone can share a picture of their setting for a keyboard channel will be ideal. I tried to learn from many articles but it's very cumbersome  and I know there are some experts here. Any sharing will be appreciated.
Thank you so much.

Hi, with eq, it is sometimes changed to suit acoustics of a room, and sometimes just for shaping the sound to ones liking.
With say, a five band eq to work with, from left to right on the frequency scales, you will have the really low bass on the first control, mid bass on the next one, overall midrange on the next, mid/highs, then really highs on the last setting.
With the low bass, dont have it too high or the sound will be very muddy, best to have it just above the midway setting. The mid bass you can boost a little, the next one, the midrange, I never have above the midway position as it can make for a very ''hollow'' type mix. The mid/high you can have up a little, and the last one can be up above the last one. If you have them set correctly, in a graphic eq, with slide controls, it should look like a ''smiley face''. With digital controls, as in keyboards etc, it will display the cut and boost settings as a digital readout number, but you can adjust them the same way, only you will have digits to go on, not mechanical sliders. It will show you a ''0'', which will be the midway setting, and ''plus'' numbers will mean above midway, and ''minus'' will mean below midway. In parametric equalizers, you can change the actual frequency that you will be working on, for example, with a fixed eq, the low bass may be set on 50hz, but with a parametric, you can change this and then cut or boost to your needs/ liking. Hope my years  of electronics/music tech stuff helps you.

Hi Linson --

I play as part of a church group (piano plus 12-string plus synth). We usually have a cantor and a small choir. The mixer is an A&H Zed-18, the two stage monitors are Yamaha DBR-10 and the main PA consists of two Bose column line arrays (permanent installation).

There isn't a "one size fits all" solution for EQ. I prefer the synth flat (no cut or boost), but find that the DBR-10s produce a lot of bass, especially with organ voices. Enter the compromise. The Bose column line arrays are bass-light, so I don't mind some extra bass from the DBR-10s. They function like a sub woofer in that regard. The column line arrays are so bass-light that most of the bass is coming from the DBRs.

In the end, it comes down to what the congregation hears. I sometimes have our music director take over on synth while I go out into the church and listen. The MD plays along with the other members of the group. Then, I make decisions about what to boost or cut. Ears are the most important tool. We make decisions about mic EQ and piano EQ the same way.

I do cut bass a little bit on the mixer, but I also cut the bass for the organ patches on the instrument itself. I don't try to solve that problem at the mixer since any setting on the mixer will affect every other voice that I play.

Hope this rambling reply helps -- pj
