In a previous post I discussed how I try to have good audio quality for my livestream with OBS, by linking up a mixing desk I use for all live performances with a studio audio interface that I use for live streaming. So the idea is that when I know how to mix my live performance I can also livestream that mix with good audio quality. OBS supports high quality audio with an ASIO plugin, so all is great.
The mixing desk I use for live shows and streaming is the Zoom LiveTrak L-12. Lately I started using a separate laptop to do the livestreaming, not hooked up to the studio. For a livestream I would switch over the interface cable to the laptop. Only a few days ago I realized that the L-12 itself is an audio interface and I slapped my forehead.
Sure enough, when installing the L-12 driver software and starting up OBS with the ASIO plugin, I could find the Zoom device. After assigning the master output channels to the OBS inputs it worked immediately. So now the setup is way simpler. The livestreaming laptop is hooked up directly to the mixing desk. The master mix now is hooked up directly to OBS.
Now I asked myself, can I use the same trick to hook the L-12 directly to an iPad or iPhone to do livestreaming on Instagram, or other phone based streaming platforms? The L-12 can connect as a class compliant interface, so its no problem to hook it up to iOS devices. Software like Garageband will find its way in the Zoom inputs and outputs. You have to set a switch for this on the back next to the USB port.
However, the master outputs are not output channels 1 and 2, so iOS devices cannot pick it up as the default audio input. So no easy live streaming on the iPad or iPhone directly from the L-12 unfortunately. For this you will need to hook up another class compliant interface that picks up the mix desk outputs and does output the master mix on channels 1 and 2.
