A DP is shooting a host/talent type of interview in a noisy event.
Here's the set up:
2 lavalieres mic: one for the host, one for the talent.
A boom
Ch1: Lav 1 & Lav 2
Ch2: Boom

Does it make sense?
 
i would do

Ch1: Lav 1
Ch2: Lav 2

And try to record the sound from the boom on a external recorder if necessary, keeping the two speakers on separate tracks would be a lot better in post.
 
this is why I posted.... It seems weird to me to put both Lav on the same Ch.
Is there a way with the 150 to import the audio discrete on the same channel so Lav 1 and 2 are separate?
 
I'm with eiker_ir...

Ch1: Lav 1
Ch2: Lav 2

Depending on the directionality of your lavs vs your boom mic, one might be better than the other. For noisy stuff where noise can't be controlled, I use a Sennheiser ME-66 on a boom. Any other time that I have control over the audio, I use Ch1/Ch2 lavs for documentary work with the HVX200s at work and my HMC150 (Sony ECM-44B omnidirectional lavs).

There is no way to record Lav 1 and 2 on the same channel while retaining independent gain control (i.e. L1 panned left, L2 panned right on a mixer, mixer feeding CH1...). Your camera has 2 analog XLR inputs. The three pins are hot, cold and ground. Only one channel! You will not get three discreet audio events from 2 analog channels.
 
Is this through a locations mixer then into the cam or direct into the cam?

If through a mixer we use 1 ch for boom and 2 channels for the lavs but boom goes to Left (CH1 out) and the lavs both output on right (ch2 output) same output. You can mix the levels separately that way but downside is you can't separate them later if they are talking over each other or one lav has background noise like being bumped by host or interviewee. Important thing was being able to keep all 3 at a reasonable level on the mixer.

So that is Boom ch 1, lav1 ch 2, lav2 ch 3 mixer inputs.
Ch1 output to Ch1. Ch 2 and Ch3 both output to Ch2.

You really do need a mixer if recording 3 sources with a 2 channel recorder. Even with a 3 or 4 channel recorder you should use a mixer. :)

If it's a noisy event the boom will not be very usefull, the two lavs on seperate channels would be the way I would go.
 
I would go chnl 1, Lav 1 chnl 2 Lav 2. if you want a back-up, then run a good mic on a boom. Use a good mixer to set your levels correctly and you're set.
