Stereo Headphone Out
Published : 13th July 2004
I will be shooting a brief clip at a small radio station on mini-Dv on Thursday for my no-budget doc.
The engineer has suggested that I can grab sound for my Canon XL1 from the stereo 1/4" headphone output on his board.
Is this a line out source? I have the MA-100 on the Canon.
Should I use an XLR balanced cable adapted on either end for the RCA inputs on the camera and avoid using the MA-100?
Any suggestions would be greatly appreciated.

Not exactly, but it has a lower impedance than your audio input does, so it should work fine. It also has the advantage of being adjustable, so you don't overload the camera's audio inputs.
You can go directly from this headphone output into the RCA inputs on the XL1, using an appropriate cable.
Set your audio input levels on the camera to about 60%, and then adjust the board's headphone volume to give you the right level on the camera's VU meter.
If you get a buzz or hum in your audio, try grounding the chassis of the camera to the outer surface of the RCA jacks -- they may or may not be electrically connected as-is. Another option would be to run the camera on batteries to remove the power supply as a potential source of hum.
The radio engineer may also be able to help you troubleshoot if necessary. (Unfortunately, the licensing of radio board operators is a thing of the past, so don't count on the "engineer" necessarily having any actual technical knowledge.)
Will all your sound be coming from this board, or will you also be miking the room separately?
