  • 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 :)

Easy scratch mic solution

A good snap of sticks will register, but other than that, too low for synching without phantom power, at least.
 
I have to ask-
with a mike mounted directly into the jack, how much FAN noise is it picking up?! I mean, its right beside the fan intake isn't it? I would think it might be useless as a wild sound mic, tho maybe for sync-ing...

The fan turns off when shooting.

The last couple of months I have been using a short shotgun mic into the A-box for scratch audio. It actually sounds pretty good, but gets in the way during some hand held moves.

In any case, a small mic, even if it needs a tiny battery (like in hearing aids) that honors the unique TRS (tip/ring/sleeve) assignments on the Epic brain would sell several hundred units very quickly. Perhaps Trew Audio or some other 3rd party audio company could whip something up?

Anybody looking to go single system with the Epic is probably best served by the A-box or something similar, but for those times when you just need something for sync/reference a tiny mic with no cable is perfect.

Does anybody know if the little Sony mic Tonaci found will work a charm once phantom power is properly enabled? Or is the TRS assignment and/or the stereo/mono mismatch still a problem?

The Sony mic works fine for Scratch Audio and is wired correctly. To much camera noise for any other use except as scratch sound for sync.
 
Phantom power is not going to make this Sony mic work better. That sony mic uses BIAS power, not phantom power. It's also stereo. With Bias power, the voltage differential is between the sleeve (ground) and each of the the tip (left channel) and ring (right channel). With phantom power the voltage differential is between tip and ring. With phantom power turned on it should make this Sony mic work worse or not at all.

RED had prototypes of phantom powered button mics a year or so ago. I don't know if those were just mock-ups or working units. Would be nice to know what happened to them.
 
In the auto setting (factory default) it is common for the fan to run slowly while recording and faster when not.

You can alter this manually though and have the fan turn off completely during takes. For the most part I do not recommend this, particularly on longer takes, as the sensor temperature could rise more rapidly. I have never seen thermal anomalies in footage from my Epic, but there have been anecdotal reports of noise variance linked to sensor temps. YMMV. AS always: test, test, test.

Good information and good question!
