Hi guys, need some help over here cause i'm a noob apparently... :p
I own a MacBook pro with logic pro x, an apollo twin thunder bolt and I want to record through my fender bassbreaker while i mic it with a senheiser e906. Can someone help me? I think I have all the appropriate tools to do it but not the knowledge. Thank you so much!

Hi lazaros1994,

We need more information as to your settings in Console. It's probably a simple routing issue, but will be frustrating until you find what it is, because there are several possibilities.

From your images it looks like you have the e906 plugged into input channel #1, the Twin's power supply and Thunderbolt cables connected, and something with a red connector into monitor out. This is correct. From the photo's angle I can't tell if there is another cable plugged into the other monitor jack below the red cable. I will assume there is.

This too is correct.

Do you have the input for your mic set to "mic" instead of "Line" on the Twin? What are you seeing in Console? Do you see a signal going in?

Just for testing purposes, what happens if you plug the guitar into the Twin's HiZ input? Does that make a signal show up in Console?

Thanks for helping me! So You assume correct the monitors are all set up. Yes I am plugging the e906 into input channel #1 and the input for my mic set to "mic". I managed to record something but the sound is extremely low (as of the mic gain is low) but when i turn it up I get mic buffering or humming whatever this is called, when i touch it it'e really loud but when I play the recording is still low, my waveform is practically non existing. I get a signal but too low. My amp is set on 10 watts and my volume is 3/10. Do I need to crank up my amp??

Okay, I see what's happening.

The Sennheiser e906 is a dynamic mic with a low sensitivity. The sensitivity of that mic according to Sennheiser's info sheet is listed as being 2.2 mV/Pa. This translates into a sensitivity or -53 dB ref 1V/Pa.

In regular English it means that mic needs a lot of volume into it - or a mic pre that will give you something in the 50 dB gain range - to output a strong signal. For comparison most condenser mics have a sensitivity in the -30 dB range. The e906 at -53 dB will give an output to the Apollo that is 23 dB quieter than a condenser mic.

THe e906 is made for recording loud guitars. Turn your amp's volume way up.

All mic pres will give unwanted noise when run in the upper part of their gain setting. If you have the Apollo's gain set above 45, it will start to give you more noise. This is why some high-end mic pres have as much as 80 dB of gain, so they can be run at 50 dB without adding noise.

So crank up the guitar amp and have at it. If that is too annoying to others in the house, then a mic booster like a Cloudlifter or FEThead will solve the gain problem, or use a mic with a higher sensitivity.

I think the buzz sounds you are hearing may be either from the mic cable placed over the amp being too close to the amp's power supply transformer, or your guitar is picking up the 60 Hz buzz from the mains (assuming you are in The States), otherwise 50 Hz.

Do you have the Pad, +48, and phase reverse engaged? It looks like the lights are on for all those things. The pad would help explain the low levels.
You don't need phantom power (+48) for a dynamic mic, and phase reverse won't really do anything unless you are blending it with another simultaneous recording of the same instrument.

So, try turning off Pad, +48, and phase reverse.

Ahhh, I didn't notice the pad. That would do it too, especially with low volume on the amp.
