preamps

Description

A preamplifier, also known as a preamp, is an electronic amplifier that converts a weak electrical signal into an output signal strong enough to be noise-tolerant and strong enough for further processing, or for sending to a power amplifier and a loudspeaker. Without this, the final signal would be noisy or distorted.

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.

Line-in before mic preamp on some mixers

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.

Preamps for recording Godin & Taylor

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.

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 !
