I’m confused, frustrated

Alesis MultiMix8 USB FX seems to be producing very distorted audio, help?

Hi, first off I want to say that I'm not very skilled in audio production in comparison to video so I don't really know what I'm doing, but my friend and I started a podcast and I was recommended an Alesis soundboard to use for it.

I purchased the MultiMix8 USB FX model through Amazon and tried it today. I am using Adobe Audition to record and an AKG D 8000 M dynamic microphone (given to me by the Guitar Center guy after I told him my purpose for it and it was $50). I am also doing this on a MacBook Pro.

After plugging everything in and finally seeing the board light up by using the power adapter to grab power I tried recording and everything came out sounding super distorted and very electrical and just.. wrong. It's hard to describe. Im not sure if I need to change any type of settings in Adobe or do anything different on the mixer but I believe I was trying to run the board through Audition as a sterio input, but it would only say something like USB Codec - Front Left. I messed with the Gain and EQ and stuff on the board too but it still always came out sounding the same way. I plugged in my Blue Snowball USB mic and the sound quality was much clearer and more normal.

Also not even sure if I need the 8-channel one for my purposes?

So, is this ignorance on my part and not adjusting something correctly in Audition/my MacBook or could it possibly be the microphone? It's cheap but it's brand new. Not sure if it's a cardioid or anything though. Any help is appreciated!

TL;DR: trying to record for a podcast through Audition and getting really awful sound quality, unsure if soundboard or microphone or what.

  • Hi Barnabus,

    Thanks for posting. 

    Can you please provide me with your full system specs? 

    It's likely your symptoms are due to improper gainstaging. I've included a helpful guide below that will walk you through how to properly gainstage your equipment:


    Let me know how this goes.

  • Hi Bill, sorry for the late reply! Thank you for helping, though. Here are my system specs:

    MacBook Pro (Retina, 13-inch, Early 2015)
    MacOS High Sierra (Version 10.13.3)
    2.7 GHz Intel Core i5
    8 GB 1867 MHz DDR3
    Intel Iris Graphics 6100 1536 MB

    I checked out the link you provided and it doesn't really seem to apply to my scenario or offer anything helpful that I wasn't already aware of. I'm recording casual speech, so much of what's written doesn't seem totally relevant. When attempting the recording, I had to crank the gain all the way up to hear anything through my headphones and would still only get the tiniest of waveforms on my timeline while recording, and a ton of noise/distortion.

  • Make sure that you don't have the phantom power engaged on your mixer. Have you tried using a different set of cables with your microphone and mixer? Do you have any other programs running at the same time?

  • I did not have the phantom power engaged. I only had the one set of cables unfortunately, and I would run Adobe Audition at the same time, but there has been a new development: upon trying the setup at my house it produced a clean sound with no interference/electrical sound, though upon trying it at my friends house where we do the podcast recording, despite my plugging in the cables properly, I would still get this electrical/static undertone disturbing the sound.

    I figured there must be something going on with his environment, something not quite right with the electricity running in his outlets since after turning nearly all of the electronics in his room off, we'd still hear the interference. I plugged in my USB Snowball mic and the sound was clean, so I decided it must be that. For now I'm going to return the other equipment, but for the future, is there a good way to combat this kind of potential electrical interference other than simply using a different recording environment?

  • Yes, I would agree with you in that this sounds like an issue with the current within your friend's house where you were initially using the mixer. That being said, I would recommend contacting an electrician to have this remedied.
