Ive never used a marantz etc, but are you putting the card into the computer , or linking the marantz to the computer by cable.
is the card formatted in a format that the computer recognises?

A decent camera (NOT DSLR) will have perfectly adequate audio inputs on XLR. IT should (to be decent) offer phantom power also, so yes you can then plug a 48v powered mic directly in.

To use a phantom powered mic without this “decent” camera you will need a phantom power supply (external) costsing more than your DSLR likely, or need a mixing desk that supplies phantom power.
Phantom power (48v) really is the pro domain.

Im not going to encourage anyone to try to plug audio into a DSLR. If you read my back posts youll see Im not a fan of this technique.
DSLRs shoot nice pictures. i have one myself, and it is capable of full hd etc etc pprime lenses etc, but audio is a disaster in my opinion.
Record your audio spearately , correctly and well, and unite them in the edit.

Hi
I applaud your intention to make the sound as good as it can be, and appreciate that budget is a real issue, but really you should be clear. £200 isnt going to buy anything other than cheap kit etc which will not be delivering quality at any level. Decent (not pro) kit just costs more than that.
Sorry

Hi
3radios is nothing, but your frequencies might be colliding or you might have 2 transmitters on the same frequency??

Interestingly tho, I have a friend who uses sennheiser g3 s into a behringer mixer who also has occasional interference problems, but I’d never thought to blame the desk????
I thought it was freqs and squelch settings.

Which radio brand is it you have and are they diversity??

Hi Vicky
Aside from any legal reasons about the use of your radio mics in your part of the world that Ty mentioned.

If the radio signal is dropping out as a result of some interference, then as youre going into a zoom h4n, which MUST be analogue input, then this CANT be the cause of your sync drift.
so lets split this in 3.

1) Is your audio arriving at the zoom ok. Your headphones will tell you if this is stable (no holes / clicks etc) If it has holes in it on the cans whilst recording, its a frequency / intereference issue (or a cable fracture) . Try adjusting the frequency to a new one, or adjust the squelch. Moving receiver closer to transmitter, unblocking line of sight and making sure there are no mobiles in room or that they are turned off.
Also check that you dont have phantom power enabled on the recorder for a device that doesnt need 48v up it jacksy.

If the cans have no issues / holes in audio, then it ia s recording error. Try a different recorder.

2) On the sync side. Have you correctly matched sample rates etc on the zoom recorder and whatever you are importing the audio into for picture editing. As the files from the zoom will be inported as a digital import, the sample frequency , bit depth MUST match. What NLE (editor) are you using.? Go for 48k 16 bit if in doubt.
If they are mismatched they will drift over time. Teh camera MUST also agree with these settings.

3) recording looks like a line with dust on it????
1) are you going into your zoom mic or line level. Which audio connections are you using on the zoom. What connectors are u using from the radio mic, or is it coming from an amp or desk?
What do the meters on the zoom say you are peaking at?
What do your ears say. ? Are you monitoring the zoom constantly?

The zoom has a full scae meter topping at 0. Your input audio from the mic should be sitting regularly around -12 ish.

let us know how you come on, unless youve already been carted off to guantanamo bay for radio mic mis use!

Lol.

HI Neil
Yep thats about what id expect to see on the eq curve (although you did go a little harder on the hf lift than i expected)
Its a little odd to add hf and then use a de eser?? but whatever gives the result you need I guess.

1 word of advice if youre going to tinker with eq etc.
Listen to it, make the change. leave it.
if you eqy the soind brighter (as in your example) and then work with it on the timeline for an hour or 2, your ears will become accustomed to the brighter sound, so it no longer sounds so bright.
Dont then add more hf as its not a correct assesment. Trust in what you did originally and resist the temptation to tinker into the night.
Try to have a listen to any eq ing you ve done th enext day, so you can judge what youve done on fresh ears, just liek you would if grading something hard!

Which Media compser are you running?
I have MC 6.0.1.1 at home and am about to install 6.5.2.

Is not know what you could do if it’s an electrical / building thing. I’d suggest trying some other pro end speakers to see if it’s a weakness of those speakers.
You may just have to be like most video editors I know and not worry about the audio .
Lol

I don’t know about better shielding.

Have you tried bypassing the backup device for the speakers to see if the noise is better, worse etc?
Have you tried taking them to a different premises?
I guess you need to establish if the issue is specific to your building first.

Are they 3 pin at each end?
Put a meter on the cables to check all 3 cores are good.
Having a poor earth would not be good.
Is there any rf nearby. Wireless alarms, mobile phones, masts etc

Are the mains cables correctly earthed
