  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

EPIC M and NO AUDIO

Adam Eden said:
The camera only records at mic level. You need to use a proper external mixer to get audio into the camera. You cannot just simply plug a mic into the camera and make it work. Well not at this stage anyway.

You can use a simple 2 channel Sound devices mixer.... They don't cost much

Thanks a lot for your help Adam, it's working with my H4n as mentioned in the previous post plus I'm glad to understand where did the problem come from.
I love Reduser and all the infos and the help I can find in that forum!

That top handle shown is designed to hold a shotgun mic inside the handle with a special shock mount and that can be attached to the H4N via XLR and either mixed in with the stereo mic or directed to track 2. Can easily adjust output levels when required.

Michael, where did you get the top handle?
 
Michael - so the old Red EVF works with Epic fine?
 
Eric, I put my old EVF on my Epic the other day and it worked great! I think there have been reports of some older EVF not working, but not sure. Mine certainly worked.
 
If you were sending audio at line level from a mixer into an input set to mic level then you would see massive distortion.

If the default mode for the audio inputs is set to off then this says a lot about the audio quality. Is the manufacturer expecting most people not to use audio on the camera? Even a low quality built in mic on a camera is useful when recording seperate sound. If the camera crew miss the board or the director shouts cut on an end board and the camera op cuts the camera then you can still easily sync up sound with the average quality sound from the onboard camera mic.

Its very easy to test the audio components in a factory before shipping a camera out to a customer. Send in tone from a mixer at line level and if you are turning up the cameras gain controls for the audio input then they would be at about 5 to 7 if the gain goes from 1 to 10

Tone is sent at -20 dbfs from your mixer and you would be lining up the camera so that it shows the same on its meters -20. DBFS means the db meter is full scale which means digital, so the meter is 0 at the max and all the other levels and negative below that zero point

You might decide to play it safe and line up the tone to -22 dbfs on the camera. Most cameras dont have great limiters for audio so you are counting on the audio mixer's output limiters to catch any spikes and compress them before they go into the camera's audio circuits. Most camera manufacturers dont bother spending money on good mic pre amps, analog limiters or a/d convertors so it can be a bit too easy to distort the camera's inputs

I think Red could have asked sound devices to consult on, recommend and test the audio side of their cameras. It would have been time and money very well spent.

Perhaps they feel they dont need to or dont want to hand that over to a pro audio expert but its dissapointing to read the customer's experience with audio on the camera here!
 
Anyone got an epic to work with rode videomic or sennheiser evolution g2? I'm not getting any audio levels. I figure the sennheiser is a line conenction and the rode should be mic.

Isn't the Rode a stereo connector? Both of the Epic inputs are wired as TRS/balanced mono connections.
 
Yes it is... do i need an adapter to get this to work? The sennheisers are also stereo line connections.

Yeah, had to talk a client through this the other day. Ended up advising them to (if possible) tape over the ring contact on the Rode plug.

Seems like one simple answer is to split the stereo signal with a Y adaptor and send each channel into one of the Epic inputs. That may mean (?) your inputs are now unbalanced but I don't think that's necessarily a problem.
 
Had a complicated work around from adapters that were present...

1. Stereo mini jack to 1/4 inch male stereo jack
2. 1/4 inch female to 1/4 inch female stereo jack
2. Male stereo jack to XLR male
3. XLR female to male mini jack
