MXL 770 quiet and loud hissing

My MXL 770 is very low volume and there is a noticeable hiss.
I haven't used it in a while and the last time it was on a different computer and it worked fine.
I use a Neewer 48V 1-channel phantom power supply.
I am not very experienced in troubleshooting this kinda stuff so if anyone could help me thatd be great!
I put an audio clip so you can see what I mean.(gotta crank the volume)

MXL 770 picking up weird hissing noises?

For some reason when I'm in fruity loops my microphone picks up buzzing sound and hissing noises.

mxl 770 cardioid condenser microphone paired with a Neewer 1-Channel 48V Phantom Power Supply with Adapter, BONUS+XLR 3 Pin Microphone Cable for Any Condenser and

SiYear 3.5mm Mini Jack Stereo to XLR Female Microphone Cable, Unbalanced 1/8 inch to XLR 3 Pin Interconnect Cable Cord Adapter (1.5Feet) to connect to my pc

this is what i have going on

how to use MXL 770?

I have purchased the MXL 770 and connected it to my laptop with an usb-XLR cable like this one because my laptop doesnt has a microphone input : ( )
And it don't seems to work neither on Fl Studio or Audacity.
Im a total beginner for all what is recording. I understood that I would need an audio interface to use my mic but I really don't know if that's what I need, which I need, or if there's another option.

MXL 770 really bad hum

I have a problem with my MXL 770 mic
Yesterday that was all ok.
But now i hear so many background/static noise from the MXL 770.
I attached file with that hum.

What can i say more..
It is not problem with mixer or cable.. i was connect mxl 990 with the same cable, mixer, and input channel
and 990's haven't problem.

Could you tell me what happened?
How to fix it?

Thanks in advance


Static/Background noise on MXL 770

I'm using the MXL 770 along with the Behringer U-Phoria UM2. Now, the Behringer use to make a lot of noise until i updated a driver. I knew it was the audio interface since i disconnected the actual recorder from it, and the laptop still allowed me to record. Now after that problem is gone, i still find background noise when connecting to the condenser mic. When i turn the mic down to a small level, you don't hear the noise until you speak, then it distorts your voice. When at a higher level, you can hear the sound in the background.

2nd in a Series - Re-ribbon, new transformer and 3D printed parts for MXL R144

Hello, this is a second in a series of Ribbon Mic upgrades. Thought you all might be interested.

Here I updated the truss to make the ribbon element floating (not tied to the truss and chassis ground) and swapped out the transformer. This required some 3D printed ribbon mounts and covers, which could also be done with 1mm thick PCB. I also 3D printed some little wire guides, so I didn’t have to sloppily glue the plus leads to the truss. Lastly, I made a re-ribbon jig for the truss, which makes it a whole ton easier to re-ribbon it.

Ribbon Microphone Upgrade for MXL 990

Hello, I’m beginning my personal little crusade in the Ribbon Mic arena.

To start, I’ve created an Instructable, to upgrade an MXL 990 condenser mic with a ribbon element from

I created some 3D printed parts to hold the ribbon element and transformer.

But I think one of the key things is I also created a 3D printed ribbon alignment jig. It makes it really easy to replace and re-ribbon the element.
