Getting an audio reference track in the ALEXA

[Joe Riggs]

Hi,

I know this is a RED forum and kudos to RED for making it pretty simple to get reference audio to the camera.

I'd like to get a scratch track into the Arri Alexa.

It has a 5 pin xlr connector and I thought it would be as simple as getting a 5 pin to 3 pin adapter and then plugging in a mic.

However, I was told because it is a line level input that it is more complicated than that?

This is what the manual says "2-channel analog line-level audio can be fed to the camera via the 5-pin
XLR connector located at the front of the camera on the camera-right side."

I'm not an audio guy, so I'm not sure what exactly is needed, but all I want is a reference track in the footage.

Thanks

Either take a line level feed from your recordists mixer in to camera or if you need a camera mic feed use a mic and mic amplifier alternatively there is a Microphone from AT that offers line level output that should work.

Id sugest any on camera mic should always be regarded as guide, never use it for programme use. The mic position is always wrong for starters.........

Custom audio cables to Alexa and Epic cameras are available from all production sound dealers Like Trew, LSC, Sound Departmenr, and Wilcox in LA, Pro-Sound in NYC, Trew in Nashville, and TAI in Orlando. The 2xXLR3-F to XLR5-M is not exactly a standard cable, but everybody's stocks it for Alexa. Line in is what I'd advise, preferably from a wireless hop.
