thanks guys, but please bare with me here
we are recording at 16bit 48khz into the camera of course which has a dynamic range of about 96db
what iam trying to ask is.........
1-will the sound devices make the sound seem louder,
2-is the dynamic range higher than the camera,
3-and if so, how will this benefit us since the output of the 302 will be squeezed to the range of the hvx 96db range,
4- where does the 50 and 60 settings of the hvx fit into this rig
please explain, as i wanna buy a 302 but wanna make sure what i'm getting into.
i already spent 3500 on the boom rig. thanks for your patience with me.

1- yes, and any high quality mic pre with limiting will do the same job. The limiting means you can set your overall volumes louder and not risk overloading your channels. So everything seems louder without overloading (going into the red and digital blocking/thumping noises). Analog sort of likes distortion (cf. Jimi Hendrix's guitar) but digital, not at all.
2-yes, because without the limiter you have to watch your levels and usually set them conservatively (quietly). Although there's a trick to get around this, which I'll not get into at the moment.
3-you're raising the average dynamic range of the entire recorded take by using a hotter recording level and limiting. The louds will seem louder, the pauses relatively softer.
Think of it as a floor and ceiling in a room. The ceiling is bad (distortion), the floor is bad (noise floor).
If you use a taller room, you can get a taller person in it (hypothetically, of course, standing above but just touching the floor and reaching to just below, but not touching the ceiling). The person can be taller, right? That's your increased dynamc range, one sample.
Now imagine a bunch of people, all different heights. Some too tall, some too short. Your digital people sample, 48000 little people a second.
Well, you can, using a limiter, turn up the volume so all the people are taller, but the limiter shrinks those who are too tall so they still fit.
Now you adjust your transfer to your smaller room (camcorder's dynamic range, adjusted by a commbination of your mic pre's output master level and your camcorder's input levels) so that the people still all fit but the distance between the feet to the floor and the head to the ceiling is less. You can compress the peole too (a la Dolby) but we won't get into that. The average height of all the people is higher. Greater average dynamic range. Everything sounds taller/louder.
4-50Hz is usually for UK/European power, 60Hz for USA power. Television usually takes its sync points from the national grid (the power plug).
I have a much less expensive Beachtek DXA8 with limiter and as I set it up I could literally hear the noise floor dropping away (the hum and hiss disappearing).
Good deal.
(A difference of 6dB is double or half as loud, FYI, so even the $200 Beachtek's 103dB S/N would be over twice as quiet as your 95dB internal preamp.)

I think the -50 & -60 setting on the HVX he was referring to was the mic gain level (dBu) not Hz.
The difference with these settings is that the sensitivity will be higher if you use the -60 dBu setting. This setting only affects the mic input of the HVX. When using the SD302 this will be a moot point as you will switch the camera over to LINE input which is 0dBu.
This is also an advantage of using a mixer, as the mic pre-amps of the camera are bypassed. Although the pre's on the HVX are quite good, the SD302 has a lot better quality mic pre's.

the -50 and -60 db settings on the hvx should be left at -50.
- 60 is for very insensitive mics and you will tend to clip your pres with any of the common mics you will be using.
so ya, leave it at -50
Get a 302!!!!!!!!!!!!!!!!!!
