is the hiss normal? even before plugging guitar in

Maybe if you have the volume way up, but I havent experienced that with normal usage. Potentially a grounding issue from your power source or receptacle? If you don't know how to check that or don't have an electrician friend, you could plug in a surge protecting strip that has a "grounded" indicator light to see if it lights up or not to signify if grounded.

Shouldn't be any hiss. Mine does not hiss at all. Just checked on different volume levels. It does click a little like all amps for a hair of a second. Has feedback if guitar is setting close. Your saying not plugged in yet. Should be no hiss. I get no hiss whether guitar is plugged in or not.

That is what I had awhile back. You will hear a different. There is no more hissing or noise in the background. The copper wall in the card that divide the circuits is a plus to prevent the noise and hissing.

Hissing may be water inside the innards where it shouln't be. I would return it for an exchange if I were you. I hope you kept the packaging!!!! Call them first to tell them you are sending it back. This device should not make hissing sounds--loud motor noise seems to be the norm, though! --SuAnn

Have you tried switching your cable? I've never gotten any humming when playing this, either through a tube or solid state amp.

Is the hum coming from the power adapter itself? If so, it might be getting ready to go bad. Replace before you have a fire. If the hum is from the speakers, re-post and I might have some suggestions for that as well.

There could be a few reasons for this, the two most likely are, 1) your cell phone is near the amp, which will cause a hissing noise similar to what you are experiencing, or 2) you have an impedance issue, the Vali is supposed to work better with higher impedance headphones, I think in general headphones rated below 52 ohms will show the noise floor (hiss) of the Vali. However, the hiss should be covered by audio in play.

there is some static noise yes..as with many amps...but if it is minimal when playing..you are good. If not, I would contact the seller.

In my setup there is no hiss or background buzzing in the background. I can have the volume knob at any volume setting and its dead silent with music off. The hissing and external noise might also be coming from your sound card, if your using onboard sound. I have my emotiva plugged into a Sound blaster Z gaming sound card. Hope this help answer your question.

it has a loud hum . I grounded the units directly to the Case of the Computer. It reduced the hum significantly. I replaced both units just last week because these are pretty much junk in my opinion.

I don't think I've heard any on mine. If you are hearing the hum while using the RCA jacks then maybe trying unplugging it from USB/have the turntable and speakers on separate outlets. If you are hearing it over USB then maybe just try the same isolation but between the computer and the turntable.

Are you using a wall power supply or battery? The power supply could be injecting a 60 Hz hum. Try a battery and no power supply. If there is no hum, replace the power supply. If there is still hum, check your cables, switches & pots in your guitar and then your amp. Still hum after all that, the pedal is probably bad.

There's a little hiss I guess - no more than other powered amps - sure it can be used for computer speaker - it's just a little bulky and square. I've enjoyed having the battery powered flexibility and Multi channels and reverb fx. It can kick out really full sound too.

I use the audio out on the Duet through headphones, but if you're getting a bad hiss I would think you'd want to check the settings that you're using in the Maestro configuration page. Be sure that if you're using a microphone you have the input set to Mic and adjust the dB parameters appropriately. On mine it sounds really good, but you do have to tweak the settings.

I had no hiss, but check inside the bottom of the speaker I did have a piece of plastic wrap packed inside that caused a noise. But once I removed it, it was fine.

Speaker hiss no but if u have a cd on at low volume that happens sometimes in some radios don't worry about it

I'm not having grounding noise issues. Are you sure the feeding devices are properly grounded?

Yes I have the same hissing sound on my unit too. Not too excited about it either. I am from Canada, and shipping it back and forth to the USA will be too much of a hassle and too expensive to do, so I'll just keep it as is. :-(
