The DijonStock Digital Home Recording Support Forum

Hi
Got sent a link to this forum, and I am extremely happy to have found it! What I am not so happy about is the hissing noise eminating from my Yamaha AW16G. Recently picked one up second-hand and began working my way through the functions, the demo song was erased, so I tried recording a sound clip. Once i began turning up the stereo fader and the gain on the guitar, a terrible hiss began getting louder and louder, at first I thought it may have been the fact I was using an unbalanced source, but it occurs even without equipment plugged in. obviously to get the optimal recording performance, the stero fader has to be set relatively high, but this sound is still present even with the stereo fader at about the halfway point, it just gets louder obviously as I turn the monitor and stero fader up. I live in England, so the appliance is grounded via the mains, I haven't been messing with any EQ settings, I don't think there is any guitar emulation activated, and It is still there without any gain applied.
Sorry for the long first post, but I just want to be as thorough as possible in explaining the situation. Really could do with some help!

Your poat title misleads me some . With no equipment attached I'm guessing you mean no input devices and the sound is comming from your monitors. Does the sound go away when you turn the input gain knob counterclockwise ? Are you plugging the guitar in the high Z input or the mic/line input on channel 8 ? Are using a pedal with the guitar ?

The preamps on a G are quite noisy with gain knob settings above 12 to 2 o'clock. An external preamp is commonly used with a G to keep the noise down.

Yeah, my first move would be to turn the input trims all the way down and take it from there.

How's that coffee this morning Bob ?

The coffee's always good. It's lube for the brain.

The sound is present without any instrument plugged into the AG16, and even more present when a piece of equipment is plugged in, with the gain set at 0 and the stereo fader right up, there is a still a very audible hissing noise, I am monitoring the sound via a pair of Technics RPDJ1200 Headphones (I use them for DJing, haven't got a dedicated pair of monitoring headphones yet), and I know that it is not them creating the sound, because they work fine with everything I use them with. It occured to me that the adapter I'm using is not grounded, could this be a possible cause? I have just been online looking for a suitable adapter (220-240v), but none of them appear to be grounded.

Welcome to the forum. Enjoy your stay.

The G doesn't need to be grounded (according to Yamaha). That doesn't mean that grounding doesn't solve your problem - I was grounded quite a lot when I was a child and that certainly kept me from creating noise.

Even though the general opinion about the G's pre's are that they are noisy, it IS possible to make recordings without any hiss, even when you'not using preamps. I used Rode mics for that.

First thing(s) I would do is: turn all preamps down, slide all the track faders up and down and then to their proper position (it still might be a leftover scene), and hit the scene button and activate "initial data".

Headphones (wired) can't be a source of hiss, so that's good.

Hope it's not a bad unit. Sounds (no pun untended) like maybe a noisy output amp then. I'ld still wanna try it out with a pair of monitors or patch the stereo outs into two separate guitar amps and see what happens.

Could be an old scene gremlin. For instance, even with all the preamps set to 'zero' if there are compressors setup for the inputs and more specifically on the stereo out, the sum of the compressed internal thermal noise could be very hissy. I suggest checking out resetting your scenes, or if you are feeling brave... I would install the operating system update, effectively CTRL+ALT+DELeting the G.

Guys? Whaddaya think?



It's true hey Robbie?! My NT1 has like ZERO hiss, and actually has a significant 12k presence peak... very quiet mic...

Wow, thanks for the all tips guys, really appreciated! I'm gonna run through them all one by one, but if the noise persists, I think I may have to take it to a repair workshop. Once again thanks for all the tips.

Certainly like to hear how this turns out.

mrskygod, when you say a bad unit, are there a known quantity of units out there that had specific problems when they came off the manufacturing line? Or are you refering to a part of the AG16 like the internal drive?

I have been using my G since 2003 or so and have been a member of this forum and it's predecessor for a half decade or so. The problem you describe is one I havn't heard of not only commonly but ever before. Wished I was next to it to run a few tests but it's starting to sound like it might need repairs.

sorry to bring up an old thread but what ended up happening? My unit is doing the same thing. Are you still out there? or did you throw your unit in the trash and start over?

Hi there.

Have you tried resseting all tracks or loading scene 0 to reset the device ?
