Input noise/buzz/hum



  • Hi

    I'm pretty new to Bias Amp 2 and although I find the tones amazing I'm a bit confused about the noise levels. I've read online and ofc there's a multitude of things that can cause noise but I feel like Bias Amp 2 is adding a lot of noise and I wonder if this is normal for other uses?

    As you can see from the screen shot this is the noise level using the "British Rock 50 v2" preset downloaded from ToneCloud and untouched by me. My guitar (Tele with humbuckers) is plugged in but the volume pot is totally off. I'm resting my fingers on the strings to mute them. i.e. no gain from my guitar at all to try to produce a "base level" of noise. If I have the volume pot fully open the noise seen here roughly doubles. OFC with the noise gate on the noise totally clears up but I find that a bit distracting sometimes when playing/recording. Personal preference possible?

    Using any of the clean/blues presets are all fine however and have zero noise (proving my interface and cables are fine?) the gainer the preset, crunch > hi gain > metal > insane the more noise I get. Some presets have more than double that shown in this screen shot and are overwhelming without using the noise gate. I can understand a bit of noise either genuine from my signal chain or synthetic from the software but this all seems way too much for me. Or am I wrong?

    Are these levels of noise to be expected? Do others just use the noise gate and don't worry about the noise level? Or am I doing something wrong?

    For reference I'm running Windows 10 on a fairly well specced machine fully updated. Bias Amp 2, latest version. Focusrite Scarlett 2i2 with the latest ASIO drivers. Cables are all decent quality and recently purchased. Other than the noise I can't praise this software enough. I have no CPU issues or input lag that others experience and the tones are superb.

    Any help and advise would be greatly appreciated.

    Many Thanks



  • Really surprised no one has replied to this. I am really the only one with noise/hum issues? Or do other people just use the noise gate even on extremely gainy presets?

    I've spent most of the week using Amplitude and there's virtually no noise at all so this is 100% a Positive Grid problem. After having such a good experience with Amplitude I'm considering ditching Bias Amp and Bias FX entirely which is a shame as it is good software and the tones are great.



  • @rich-williamson1980 You do have the Noise Gate off in that picture. When you're using a hi-gain amp, noise gates are a must.

    What you say about Amplitube isn't entirely true. You'll notice that many of the hi-gain amp presets there have noise gate on and built into the preset. If you turn the noise gate threshold off there, the noise is just as loud, if not louder, than on Amp 2. If you don't believe me, choose a Mesa Boogie Mark III or IV on the lead channel and turn the noise gate off. Careful though, the noise will blast you into next week. :)

    Thank you for replying. Yes that's my question, does everyone else use the noise gate? As I mentioned I find the gate a bit janky when the gate opens and closes, it's not the best experience in my opinion due to the volume of the noise. I'm therefore trying to use Bias Amp without the gate if possible. Amplitude also has a built in gate but it's not really required since there is so little noise that it isn't an issue even on the high gain/metal amps.

    It feels like Bias Amp is trying to "emulate" the noise you get when using high gain equipment but it's over doing it. I've noticed today that you can tweak the distortion knob in the preamp section which will reduce the noise dramatically to a manageable level without affecting the tone in any way that I can tell anyway. It's not much but if the noise is too much at least it's an option.

    There you go, I didn't know that particular trick. Thanks.

    @rich-williamson1980 Which input selector are you using on the 2i2? I'd also suggest to try using the Instrument Level to see how it goes, check this out!

  • I've been fooling around with this for a few days. One thing I've noticed is that if I load the plugin to a stereo track in ProTools (v11.2.2, 64 bit Windows) the noise levels go up to the point of this product being unusable.

    I first actually noticed it in FX2.. I loaded it into a stereo track because I was using stereo chorus, etc. The gate widgets in the FX chain were really strangling the sustain and sensitivity of what I was trying to do and so I turned them off. Massive, ridiculous amounts of hiss. Like "your amp is on fire" levels of noise. The noise was registering about 20 db below the guitar/amp levels on the master fader meter, which is just insane. For any amp, ever.

    I didn't remember this from playing around with the same amp model (JCM 800) in Amp 2, so I removed the FX plugin from my insert and replaced it with the Amp plugin. Still gobs of noise. Then I noticed it was all in the channel that didn't actually have any guitar signal present. This side should really be dead silent, but it isn't, by any means. So, why is the plugin generating noise on the unused side of a stereo channel?

    I deleted the track, created a new mono track, added the Amp plugin and voila, noise is gone.

    Yes the amp models have a noise gate built into them in Amp 2, but if you turn it off (on a mono track anyway) you get the normal kinds of hiss and hum you'd get from a JCM 800.

    So, something is definitely broken, somewhere. For me this seems to be related to stereo processing.
