two mics one boom at DVinfo.net

Pietro Jona · November 9th, 2006, 03:37 AM

ok, for nearly two years now i've been hired, given some kind of tool and asked to gather sound. most of the times the gear i used was not ideal for the shot but nobody ever complained. i guess it is something that happens to many of us here.
now i'm going to be working on a more serious thing, it is something that i like and i want it to have the best possible audio.
the guy that we'll follow will be moving in interiors and outdoors and i'll have no time for changing mic on my boom. what i'm thinking is to find a way to stick a mkh416 (or similar) and a cmc641 in the same zeppelin. two wires would be coming down the pole to my sd302, two channel both sent to camera's ch1 (just need to ride levels to decide wich mic is better in wich case), the third channel sent to camera's ch2 with a lav clipped on someone or used as an ambient mic hidden somewhere near the action. this way i could use the hyper indoors and the shotgun outdoors or even indoors if i ever need more reach (it is going to be a documentary so a bit of reverbering sound won't be too bad -empty rooms are supposed to be reverberant on a wide shot).
my only doubt is about positioning a cmc641 in a long zep, like the rycote n.4, toghether with a shotgun. how do you see that? i might put just the capsule, but still it should be fixed at the very front of it otherwise it'd be too far for the speaking mouths..
thanks for the imputs!

If both the mikes are phantom powered and have radio-frequency circuits in them (not the same as radio mikes) be mindful you might get RF interference between the two if you have both powered up at the same time.

It happens if you put old Sony C76 and Sony C74 mikes closer than about three inches from each other on the same pole.

IMHO, there's no reason you couldn't use the Schoeps outdoors as well. There's nothing sacred about shotguns for video and unless you need the slightly extra reach and rejection of environmental sounds that you would get 416, the hyper should work just fine both indoors and out. Using just one mic for most of the shots makes the problem of quickly changing between two go away.

steve,

the reason for using a 416 ora another shotgun would be the reach.
it is going to be a kind of run and gun documentary and sometimes i'd be far from the speaking person. i know this is not good but it is the only way i can manage to get ANY sound. i have worked with a 416 outdoors and picked sound from -say- 5 or more meters away sometimes. that was BAD audio but still usable in such circumstances.. how would a cmc641 work in such a case?
of course for me it would be much better to work with only one mic, lighter boom, half the money, half the worries..

In that situation I'd go with a cs3e. It works suprisingly good indoors (supposedly better than the 416, but I've never done a comparison) and is fantastic outdoors. It's an amazing mic. It takes a lot of skill to use though. It's not forgiving off axis at all.

good idea - but i will like to correct , the 416 has much more tighter pattern , but doesnt reject low frequency from of axis , the cs-3 other way , does it much better .
also think that this is the best one for in/out situation
by the way you can place both mics inside the windshield but without the foam .
Manfred klemme(k-tek) make 8 rings to hold 2 schoeps together inside his rubber holder( good for every suspension) . the 8 rings have 20 mm holes and the 416 is 19mm , so you can add small pease of gaffer inside make the diameter suitable .
you can also make 5 wire cable with 2 xlrs on each end ( the same as we use for ms recording) and use both mics simultaneiously .
but - do you really want to carry 300gr mic ?:-)

marco
thanx for the suggestion.
oleg
agree with you about the weight.
i never used a cs3, how does it behave compared to a 416 outdoors? reach, sound..
