Hello Everyone,
I’m a new user but would like to ask for help or advice on a sound issue.
I film via a mobile phone to zoom our Sunday Church service and have an audio lead running from the mixer desk to an iRig2 then into the phone which seems to work,
The only problem is the vicar has a wireless mic and the sound “when you watch the video back” has an echo, but when a reader goes to the lectern to read the sound is perfect “as that mic is plugged into the system” so not sure what is the problem with the vicars mic when recorded.
Just to say I have run sound test with the vicar’s mic on Facebook live, zoom and just in church with an external mic on the phone so any help would be great but we don’t have a lot of money to spend on equipment to sort this.

Trying to understand exactly what's going on here. Is the vicar's wireless mic plugged into the mixing desk as well?
Is the phone also capturing sound from its own mic as well as the iRig2?
I wonder if the 'echo' is because you're getting a direct feed from the radio mic as well as an acoustic feed -- which will be delayed by the distance of camera from vicar.

What you're trying to do with an audio feed from a church sound system can certainly work with no artefacts - I do it occasionally with no problems.
As Hugh says, it sound like you have some unwanted duplication of sources/routing which is causing the problems. There's nothing inherently 'different' about a radio-mic system so that can be discounted.
But some idea of how you're connecting things both to and from the sound system may help.
A remoter possibility is that the vicar's radio mic is either inappropriately placed or the sound is being picked up by the radio mic and another mic connected to the sound system. Humans are remarkably adept at tuning out such acosutic funnies - recording systems are not!

I think it would be helpful to know what the radio mic is, what the desk is and how it's all routed both to the main church FOH speakers and the zoom system.
As Mike says radio mics and wired mics are all pretty much the same as far as the mixer goes.
Thanks everyone for your replies.
The vicar has a Wireless Alto Professional Radius 100 H lapel mic and the receiver is plugged into the Mixer which is a Sound-craft EPM 8.
We used a Samsung Mobile the Sunday just gone for filming and the echo was there when the vicar spoke but clear as a bell when the readers used the static lectern microphone,
So Im not sure where the problem is.

Could it be that the lectern mic (or some other nearby mic) was left faded up on the mixer when the Vicar was talking over the radio mic?
The echo effect strongly suggests there are two signal paths involved here, one experiencing a delay which is probably an acoustic delay because someone is a long way from a microphone.
You'll need to figure out what those two paths are.
Is this echo sound audible at the output of the mixer (you could probably check with headphones plugged into the mixer)?
