Blackstar Unity Elite 700 white noise issue

Hello all. Today my Blackstar U700 head began making a great deal of white noise. This happens only when a cord is in the input and the noise is affected by eq and setting changes. I have tried different cords, ac outlets, and cabinets and the issue remains. This happens with or without a bass plugged in. Has anyone had a similar issue or can anyone give me any suggestions what the issue may be. Luckily it is under warranty, but if this is a common thing I may consider a different head. Thanks

 

Hi, thanks. It isn’t an interference issue, the amp is making a noise like a tv on a channel with no station, thanks though

 

Thank you no. it’s not a battery issue. It is beyond the sound of a cord not connected to instrument. Pure white noise. Thank you though for trying to help

 

Hi folks, thanks for your replies. It has been determined as not a normal thing and I am awaiting warranty reply. I apologize if I have not directly replied to your responses. I don’t often use these forums so may not have replied properly. Cheers , thanks

 

Agedhorse. Thanks again. I understood your question or suggestion but perhaps did not give a clear answer. This happens only when a cord is plugged into the amp input. I had said this in the OG post but was perhaps unclear. Anyways I brought it to the store and all agreed that an amp should not make such a noise. I am a bit underwhelmed by the amp as this happened in less than a year under fairly light use. I was also told that the 1 other of this model came back for the same reason. The store offered me a replacement with no eta or the option to upgrade for a small fee to a different amp. I am up in the air between an Aguilar Tone Hammer 500 or an AG 700. Anyways thanks for the input, cheers

 

Thank you, this wasn’t the issue and a replacement has been offered, Cheers, thanks again

 

It sounds like white noise similar to a tv on a non active station. Like I said it is an amp issue determine all involved to be unfiixable, or not worth fixing.Thanks again

 

I think we may have a simply fixed misunderstanding in our communications. If you we’re trying to educate me on what could cause this issue on a functional amp, I appreciate that you shared your knowledge. I will also use your terminology in the future. I was seeking an answer to see if this was a problem people have had with this amp model and if it was fixed what the issue was. If any miscommunication transpired I apologize if it has not been clarified. Thanks again for the info and I will refer to it when required. No offence intended there Brotherman and I hope you have a good weekend
