My stream’s analog audio inputs sound okay on my website, BoxCast.tv, or YouTube, but sound terrible on mobile devices and/or Facebook Live!
This happens when the positive and negative sides of a balanced, mono source are connected to the L/R (white/red) channels of the BoxCaster’s analog audio inputs.
If you’re not sure what the difference between “balanced” and “unbalanced” audio means, check out this blog post we wrote about it.
The BoxCaster has stereo, unbalanced RCA jack inputs (meaning that there are two unbalanced RCA audio inputs; white/left and red/right). It is not designed to take in balanced signals. Splitting a balanced signal into the left and right inputs of the BoxCaster may result in lack of audio due to phase cancellation when the stream is summed to mono on some devices or platforms.
How do I fix it?
Try unplugging the red side and see if that helps. This may solve your problem immediately.
If you are getting your audio from a soundboard, try to use an RCA-to-RCA cable if it’s at all possible. If you are converting from an XLR to RCA, make sure that you are only converting to a single RCA plug. If you’re using a cable or adapter that converts from a single XLR to both red & white RCA plugs, this is likely the issue. An XLR usually only carries a single channel of audio - it cannot feed both the red and white inputs, only one of the two. You may be able to use something like this passive adapter, or more ideally something like this active converter box.
