Hi everyone. I recently found a used FBT M12X4 preamp unit and apparently there is a problem with one of the 2 channels (tested in every input).
I have experience on repairing stuff but i can’t find any schematic or service manual online.
Does anyone have the schematic for that unit or any idea of any similar fbt device.

So many newcomers real about SM7Bs and the need for Cloudlifters or other preamps and get told yes, essential, or no, not needed. The trouble is you cannot say yes or no as a general rule.

I noticed that many mixers such as the Behringer hard wire their line inputs (without even a switch) in parallel with the mic input to the mic preamps. Yes, they do have a drop resistor but that's all. My concern is that the signal is being dropped and then amplified back up - thus adding another stage and more noise.

[Solved :)] Hi, I am fairly new to the world of XLR mics. I recently got a RODE NTK microphone and a Focusrite Scarlett Solo 3rd gen pre-amp. I use a Macbook Pro along with Ableton Live Lite and Adobe Audition. I have tried everything I can, but the preamp is not picking up the mic.

Hi everyone, new to the forum!

I'm looking into buying a preamp that works well for recording both a Godin Multiac (just using the direct sound) and a Taylor 714ce. But for different reasons.

For the Godin, I'm looking for new colors. I want to have options for some bite, beef, or low end, as I play aggressive & syncopated riffs. I don't want it to sound like flamenco.

Hi there,

I have used portable recorders starting in the 80s (WM-D3) and continued in the 90s (TCD-D8), mostly for recording piano recitals. My microphones of choice were and are the OKM-2 binaural mics by the Berlin 'Soundman' company and they served me really well.

I have an old Yamaha 3210 monitor mixer. It has low z 1/4" inputs, and hi z XLR.
From a post here, asking about the mixer, I learned the mixer can handle low/high z input, has preamps, and was built to deal with the different signals.

In this video, I compared all my preamps with 2 different mics (Shure SM57 and Microphone-parts.com T47 DIY kit) What many want to know is if an external preamp even the cheapest is better than those included in an interface. And how will they compare to highend preamps.

So here it is, let me know what you think !
