Title: Help with cheap wireless lavs
Post by: Kirby Yarbrough on July 27, 2011, 05:18:48 pm
Worked a show last night, talent had two PG series lav mics on a two-channel receiver.  They stayed back of the mains, but I was fighting feedback all evening.  I used narrow cuts on four different frequencies on both channels with an HPF and another narrow cut in the mid-high range on the mains.  Short of bringing better quality wireless gear, is there anything else I should have done?

Throw the lavs in the trash and gone with a real mic.

But seriously, I avoid lavs as much as possible. They must have been omni directional. About all can do is make sure they are as close to the mouth as you can get them, eq the best you can, have them stay away from the mains and ride the fadders.

What did you have available for this?  How many filters and usable band width?

Just curious.

Two channels on an LS9-16, so a four-band parametric on each input, and a four-band parametric on the stereo left and right out.

 I have a pair of insertable Sabine "solo" FBX units which I can use for times like that.  They are a nice addition to the 4 bands on the console.  But you're a bit limited if you don't have inserts.......

For another 4 bands, route the inputs to groups and use the group's parametric.  Then route the group to L/R.

I greatly prefer this to using the main L/R output EQ, as that affects EVERYTHING that doesn't need EQ... and I get to use the Input channel's EQ for HPF and tonal shaping.

Have fun, good luck.

Even real nice Lavs are a pain if the surrounding noise is to high. I had to go to some Crown 311s once at a mall. it was impossible to get the levels with out the surrounding noise as well.

I try to move those clients to headset mics. Life immediately gets much easier.
The tiny ones coming out of China now are really unobtrusive and work fine.

On the LS9, you can also insert graphic EQs anywhere.
