We often do recordings with a two channel recorder, such as a Fostex FR-2LE. Often, this is just with a single radio mic, and a tutorials is available: Tutorials/Audio_recording/Fostex_FR2-LE_with_EW112P. What happens with more than one mic?

[edit] 1 Two radio mics
Sometimes, the extension to this is two radio mics: The procedure is the same as described on this page Tutorials/Audio_recording/Fostex_FR2-LE_with_EW112P, just with two mics.
This is suitable for two speakers, such as somebody introducing, and the main speaker. Or two speakers talking consecutively.
You could also use this to rotate mics, for several speakers speaking in turn: While one speaker is off-stage, you retrieve the microphone, and give it to the speaker who is on next.
[edit] 2 Radio plus directional
Another scenario is to use a radio and a directional mic. E.g. the directional mic could serve as a backup to the radio mic. Or it might allow you to mic one speaker (who can move about) as well as a lectern. This might work well if there are several people introducing, and you tell them to stay at the lectern. The main lecturer has the radio mic, and can move about freely.
The wiring would look like this:
[edit] 2.1 single speaker
For a single speaker, the mics would be arranged like this (see from above)
[edit] 2.2 round table
If you had an event with mostly lectures, but some round table discussion (for whcih lower quality is acceptable) you could mic the event like this:
It's not ideal, but if that's the only equipment you've got, then it's a good way of doing this.
[edit] 3 Capturing the audience
You could also use the previous scenario to use the directional mic for the audience. You keep the radio mic on the speaker, and you point the directional mic at the person speaking in the audience.
Another scenario is to use the radio mic for the speaker, but to use a roving (hand-help radio mic) for the audience. This needs to be coordinated well. (Ideally, you'd have more than two channels, so that you can use two roving mics, and use them alternately, which can work very nicely without interrupting the Q&A session.)
