Noise in audio recording on fantom

da-man · Post by **da-man** » 09:40, 17 May 2006

Does anyone know how to limit the fuzz or hiss noise when audio recording on the fantom? It is enough to be noticed.

I have tried with mike, guitar in, line in, mike with preamp, guitar with preamp, without etc..... and always have a bit of noise.

Plus the noise seems to get a bit worse if I dial up an mfx effect.

I am using 2.10 operating system on the x8.

You need to be systematic - you need to find the cause of the noise. Go through the signal chain and listen to it (if you can) at each stage to identify the noise added at each stage.

You haven't listed what gear you're using, but a mic will require high signal attenuation (decent pre-amp) to get the signal hot enough for the Fantom's line lever input. Some mics also have a high noise floor, hence if you amplify the signal you'll also amplify the noise.

For guitars, you'll need to match impedance via a DI box. Otherwise you'll get and horribly weak signal that again requiers a significant amount of attenuation = loads of noise.

If you then apply an effect to any of these signals, all you're doing is amplfying the noise, especially if you're using a guitar amp model.

I'd suggest you use the Noise Suppressor (or is it Noise Gate?) in the input effects section.

noise gate - and it's exactly that, a gate. It doesn't get rid of noise, it just 'shuts' the gate when an input signal is not detected. Hence you'll still have a horrible signal when you're playing.

Recently my cable being press under my keyboard stand, and it produced hiss and distorted sound. It can be simple as that.

U may change the point of cable of mic by reversing it .

noise is inherent in audio...

if you are using a Microphone preferably use a preamp and get the gain as to about -6 DB you can get it higher but thats a pretty good standard. make sure that there are no ceiling fans running or dishwashers or anything else to contribute to latent noise and make sure the meters on the fantoms sampler are showing a strong signal again about -6 db average its also good to run a microphone through a compressor so you have a good full signal coming into the fantom.

If you are using a line in... turn off all the effects using the mfx switch and see if there is any noise. if there is then it is probably in the instrument or its cable... there can be some noise caused by electronics and motors and such.

most of the amp modeling effects do cause excessive noise because they decrease the signal to noise ratio exagerating the noise... the best way to fix that is adjust the preamp gain to just below the audible hiss.and maximize the master volume...

always have your instrument at the loudest volume possible without distortion or noise. you should not have to re amplifiy the signal through each device that the signal is connected to..

hope that helps

don't forget the power supply too! I use a rack mount power strip. Also I've heard that it's good to plug everything (if possible) into the same place. Without overtaxing your power supply of course. Another ac-noise fighting suggestion: don't run signal cables (your synth outputs etc.) parallel to power cords. Ideally you should keep them separated altogether, but since this is not always feasable, when they do have to cross each other, it should be perpendicularly. I follow noise killing tips like this and my recordings are noise free! Now If I just keep working on the musical content part of it............

Some power supplies on electronic equipments tend to create a hiss/noise when connected to any auxialiary output (like i.e. Dell laptos) and in 99% of the cases have to do with improper routing of the grounding line... So a little trick to get rid of this is simply adding a-no-ground adapter.

In simple words just plug one of those orange (mostly) adapters to eliminate the ground connector on the end of your power cable.

Thanks so much everyone for your valuable input. I will try some of these suggestions and let you know how it goes.

I initially tried a bit of elimination efforts and after spending a few frustrating hours I thought I'd get some help.

Be very careful with not earthing electronic equipment - this can be leathal!

You're probably not suffering from ground/earth loops in this case - far more likely to be chasing the signal chain and make sure you've got your equipment set up properly, doing its best.

As someone else suggested, if you want to see if you have earthing problems, run all your stuff from one plug (with how ever many adaptors you require coming off from this in 'star' formation). Music gear (keyboards etc.) tends to have a very little power consumption, so when you add it all up, you probably somewhere in the region of a kettle.

The other way is to use a DI box with ground lift. this isolates the earthing circuit and hence stops noise travelling. This of course invloves more money. Get your signals straight first.

I have found the main culprit in the noise chain.

My semi acoustic guitar preamp creates a bit too much extra noise so that is why it was making noise whether going through the DI box or straight into the fantom.

I have since found it is better to record using the Behringer B2 mike with my acoustic guitar.

The DI box I am using is a Behringer Tube Ultragain 200

Thanks everyone for all the advice. The noise suppresor on the fantom works great for the quiet bits when I'm waiting to play.

OH NO!!

Behringer is a swear word! I needed a DI box too for my guitars and purchased a Behringer DI800 - wow, what a mistake, there nothing but white noise generators and quickly sent it back to where it came from (hell probably). If its not too late get your money back! If you'd mentioned your equipment before hand, I would have pointed you straight in that direction!

Glad you've got it sorted though. happy playing
