Dyneq4 weird sound?

[hunterrutz]

Hi guys,

I went to a recent dLive class and learned about the wonders of phase alignment on the FPGA Architecture, and then they showed the dynamic EQ plugins. Once I realized I could use them on SQ, I got so excited because I run an SQ7 at our church. So I got the Dynamic Trio plugin pack, unlocked it in the mixer, and tried it out on an fx bus, but something wasn’t right. There was a complete shift in the character of the sound for all channels added to that fx bus. It sounded like a phasing issue. So as a troubleshooting step, I put the plugin in bypass. That put everything back to normal. So I engaged the plugin again, but this time I bypassed all 4 bands while leaving the whole plugin engaged. It still has that weird sound. So that brings me to my list of questions.

Am I the only one who has noticed this? Does the dyneq4 plugin add latency in SQ? Is there a way I can apply this plugin in the mixer and keep from having this phasing issue? Something like not assigning the channels to the mains, but assigning them to a bus with the effect inserted on the bus, then assigning that bus to the mains. Could that by assigning the channels to a group, and not the mains, them mains + group into a matrix?

Help! I really wanna use this plugin. Lol. Hopefully this can be a simple fix.

The answers to your list of questions could be: No. Yes. Yes. Something like that. 🙂

The DynEQ, like any other EQ, is rather not intended for use as an FX.
If you mix it in as FX, you’ll get the phase problems you’re hearing now.
But you have already mentioned the correct use yourself.
Use the DynEQ in individual channels or groups (just send to LR).
When using a group, don’t forget to turn off “Assign to LR” of the used channels.

Have a lot of fun with this really great tool – except of course for the handling of the GUI. (

Yes, inserting an FX channel into an audio path adds latency on the A&H systems. This is not automatically compensated for like the other channel processing is. On the DLive system, it is 281us. I don’t know if it is the same on the SQ series. I’ve read another post on this forum where a user found it was closer to .230us.

Long story short, if you have the same audio going through multiple audio paths, don’t add an FX to just one path and not the other. For example, if you run a “drum group” and a “drum crush” group (that is highly compressed), you need to add FX to both paths, or add a delay compensation to the path without added FX.

However if you are using groups, you would normally send the desired channels to only that group and turn off the send to LR. If you want to use a vocal group for example, send all of your vocal channels to the vocal group and turn all of the LR sends OFF on those channels. This prevents having two exact audio paths being created and you should be able to insert an FX (including the DynEQ4) on the group and not have any phasing issues.
