I know there's been alot of post regarding this.
I'm using the following equipment.

Yamaha MW12Cs
M-Audio - Bx5a
Yamaha ERG 121
and a JvC mic that's Gold. I don't know the model of it.
Toshiba Satellite

Anyway when using this equipments. I hear hissing sound on my recording. I've tried using a different cable but it's still the same.

When I don't turn on Switch for an instrument it doesn't produce THAT much hissing sound. But isn't it supposed to disappear when you're recording ? It wasn't like this before. But then when I plug it in a desktop. It made hissing sound afterwards. Did my mixer broke? Is it the USB which I'm using to connect to the laptop? and I have my battery out so I don't think it's my battery.
 
More info needed:

Is the hiss being recorded or are you just hearing it on your monitoring? FYI, the his is almost certainly electronic noise from within the system. Have look at a recording of a silent bit on your DAW screen....if the "flat line" is at around -65dB or lower then the recorded hiss isn't too bad. If it's higher than -65 or so then you're recording it.

The first thing I'd look at is if you have any gain turned up super high somewhere to compensate for a reduction elsewhere. For example, do you have the input gain on one of your mixer channels turned up right to the top? Or have you turned down the monitor output of your mixer and cranked up your monitor speakers?

The other thing to look at is how you're plugging in your guitar. Are you going straight into one of the jack sockets on your mixer? If so, this could be the problem...the jacks on the mixer are for a low impedance line level source, not a high impedance instrument which is a much lower level than the mixer wants. Get a DI box to adjust the impedance and let you plug into a mic input--or use a mic on a guitar amp which would sound better anyway.

Finally, is the noise there when using your JVC mic? JVC aren't known for making mics so it could be a super cheapie (and super noisy) one meant for things like Skype rather than music recording.
 
I have a mic condenser but my mom wont let me use it. I'd probably give it a try later on. And yes. I can hear the hiss sound on the monitoring speaker even after I finished recording and played back what I've recorded. The hissing sound is still there further more, the mic levels aren't that good. I've tried lowering and cranking up the Gain level. And yes it made it worse. So you don't think that the problem might be my mixer? Thou it won't make any hissing sound if there's no instrument connected to it while it's turned on.

I'm still new in recording the and the terms that you have used, I cannot understand.

The hiss sound is being recorded not just hearing on on the monitor speakers.

Can I use this line Chvit? :thumbs up:
 
Back to your problem .....

Are you using a laptop?
 
From your description, I would have to guess it's a combination of factors: a cheap an nasty mic with some self noise into a cheap and nasty toy mixer with the gain cranked up too high so the mic pre also adds noise and a guitar plugged into a line level input on the same mixer, adding even more noise as you try to compensate for the wrong impedance and level--and finally your monitors cranked up high so they add more hiss gain.

Yeah, there could be a single culprit which you could identify by going through and disconnecting and/or turning off everything, then adding items one at a time--but my money is on the mixture of gear in general.
 
@more sound. Yeah I'm using a laptop with the battery out.

@Bobbsy: But how can you explain the change that went from no hissing to my current situation. In the past we used a desktop and a condenser and the mixer was brand new. It didn't produce and hissing sound it was actually quite legit. and my monitor speaker levels are down when I'm recording . Even if I did pull out and turn off the monitor speakers with my gain lowered it's still the same. Also, how can you explain the disappearance of input level when I'm using audacity. Sometimes it's there sometimes it's not. I'm using the same setup.
 
Try going on battery power just to see if it isn't a grounding issue with the laptop/power supply.
 
New update! I've found the source!!! FINALLY! lol

So I was tweaking the mixer here and there. There a button beside the fader which is rec and ST even thou I don't know what ST means. They were both pressed ON so I did what normal people would do. I've switched of the ST only.
Now I don't have the hiss sound from the guitar. Unfortunately not the mic. I've tried doing the same. But I guess I do have a crappy mic. Now since my mom just went out I'm going to sneak in and borrow the condenser for a quick comparison. Wish me luck!

Click to expand...

The JVC mic is almost certainly a dynamic with a very low output--so you've had to crank up the gain on the mixer to get suitable levels. The condenser probably has a much higher output. With cheap pre amps, it's not uncommon to get noisy when you turn the gain up beyond halfway or a bit more.
 
I did do that. Because I had low level input and I couldn't here a thing. I used the condenser and it was pretty amazing how big the difference it. My mom won't let me use it because it's a very delicate equipment. We need to buy a Boom stand and a shock mount. We did have a boom stand but our house in my hometown got raided! Even the freaking cymbals for the drum kit was taken! :/

This is going to be cool. :D

It usta be sneaking liquor out of the liquor cabinet. Now today's youths are sneaking condenser microphones.
 
:d

Hey,
i have the 10 channel version of mixer, and i record keys mostly, i had a hisssing sound all the time when i recorded it, i used to use a denosier to get rid of the sound. Then i bought a DI Box, as soon as i plugged it in, the hissing sound had gone...maybe this will help you out a little.
