## Points to note about inputs

- If you want to connect 2 or more sources (e.g. voice + synth + guitar), it is important to note that Jamulus currently handles only 2 input channels (L/R). So the hardware being used must provide a mixed-down stereo output to Jamulus. Alternatively, run two instances of Jamulus, if your hardware supports it, or use virtual audio inputs to Jamulus for each hardware input.
- Audio interfaces generally output a mixed signal on their analogue output, but separate signals (1 per source) on their digital output (USB/FireWire/Thunderbolt).
- Mixers generally only output mixed-down signals on their analogue output.
- Mixers with USB/FireWire/Thunderbolt generally output a mixed-down signal on their **analogue** output AND separate signals only (no mixed-down signal) on their **digital** output.
- A few Mixers with USB/FireWire/Thunderbolt will either send **only** a mixed-down signal to the **digital** output (small/budget mixers), or else also ADD a stereo mixed-down signal to the separate signals on the digital output.
- If you want to connect many sources (e.g. voice + synth + guitar), it is important to note that Jamulus currently handles only 2 input channels (either Mono 1 and 2 or Stereo L/R). So the hardware (audio interfaces or mixers) being used must provide a mixed-down 2 channels output to Jamulus. Alternatively, run more instances of Jamulus (if your hardware/software supports it), or use virtual audio inputs (1) to Jamulus for each hardware input.

(Tip: You could use a DAW with virtual routing between your hardware and Jamulus (example : Reaper with ReaRoute).)

Not sure if this change captures the precise nuances, but I prefer keeping related details together. There are ways to logically separate them inline.

Maybe "head" the bullet "Connecting multiple sources to Jamulus" and give each method its own second level bullet? I see three separate points being made, really.

- Audio Interfaces generally output a mixed signal on their **analogue** output, but separate signals (1 per source) on their **digital** output (USB/FireWire/Thunderbolt).
- Mixers generally only output mixed-down signals on their **analogue** output.
- Mixers with USB/FireWire/Thunderbolt generally output a mixed-down signal on their **analogue** and **digital** output.
- A few Mixers with USB/FireWire/Thunderbolt (sometimes called "mixerface") can send a stereo mixed-down signal AND/OR separate signals on the **digital** output.
(1) You could use a DAW with virtual routing between your hardware and Jamulus (example : Reaper with ReaRoute).

There's a "proper" way to do footnotes in markdown. Don't look at the Github markdown docs, as this is Jekyll and it uses a different sub/super-set of "standard" markdown.
