Hiss problem with Sennheiser G2?

Hey.. I recently purchased the g2's ENG kit, and i think it works fine. Except from a hissing noise in the backround. I still use the me2 mike(the one that came with the kit) and i am curius if it is this mic's fault, or if there is something i've done wrong? The sound from the mike seems really sweet, except from that his when it's quiet. I am wondering if i should by the countryman B6, but if the hiss doesn't come from the mica there will be no use.

well, this is sort of the problem with the g2, and all the other sub-$1000 dollar wireless systems: signal to noise.

they function just fine when you are iny relatively loud environment, but in really quiet (or even just fairly quiet) environments you can always hear the inherent system hiss.

im afraid this is what the G2 sounds like mr willis... on the plus side, its not unworkable so try not to worry about it, even though I know that can be darn hard. its not the mic. although a B6 will give you a much nicer sound.

timapter...does this mean 'turn a deaf ear' to the systems inherent hiss or what is 'not unworkable'?
 
it means that in some situations you will clearly hear the hiss when you record, but that the audio will not be unusable if tweaked in post. multiple g2's mixed together can cause a pile up of this hiss in soft locations - this is something that should be watched for.
 
My G2s/ME4s have been working great. I have them a quickie check tonight:

At 200 feet, I get 50 dB signal to noise ratio
At 10-15 feet, I get about 55 dB signal to noise ratio
At 10-15 feet using the ME2 mic, I get about 62 dB at 10-15 feet
At 10-15 feet with the mic unplugged, the noise floor is -72 dB

At 50dB, I can detect a tad of low frequency rumble - all easily removed in post-production with noise gate removal software. If I couldn't get 50dB S/N, I'd be hopping to another frequency, replacing the mic, or sending in the G2 for repair. The obvious first step is to try another frequency. Next try removing the mic and listen/measure the receiver noise floor. If that's a problem, try using a different transmitter or receiver to see which is defective.

One other point on the above post - hopefully we are at least separating two G2 transceiver tracks going into the mixer using left-right stereo pan pots (nothing worse than having an idle mic spoil the other channel due to the talent bumping the mic). And of course, each receiver must be set to a unique frequency - you'll have a mess on your hands if you try turning on two G2 transmitters to one receiver frequency.

Good luck, Michael

Thanx for all the reply's!!

I think i have to live with the hiss sound, and remove it in post then.
(I tried removing it in adobe audition, but i didn't quite get it. Any tips on how to remove the hiss sound using that program?)

the most obvious solution in post is to ease off the high frequencies very gently until you reach a happy medium.. there are others, but thats a beginner/easy way.

lets not confuse the "technical" definition of s/n (which is a measure of the noise floor) with signal/noise of dialogue/background...
