If you’d like to support the channel or leave a tip in the jar to buy me a coffee if you found this video helpful to you.
In this video, We discuss compression on the Behringer MDX-2600. Most other rackmount units are slightly different, however they will all have the same controls more or less.
Never really understood how compressors work. This explains it very well! Thank you very much!
Happy to help!
Thanks, right up my alley.
I have the Autocom model 1200. I ran audio thru my box and set the settings, but this gave me a better idea of what was happening.
I may use the 2nd channel for the rig's output. Not sure, I like the audio on my RS 918.
W8BFO here - this was an excellent video for understanding the compressor as well as the DE-Esser which is a strange term, but perfectly explained, I am hoping to get my eSSB setup this winter so keep your ears open for me George. Thanks and happy DX mate!
Cheers mate. Thanks for dropping by! 73
As we're only using one channel, another neat trick is to use the right channel for normal communications, then you can have more 'extreme' settings set up in the left channel (I'll explain why later) then when you hit the stereo link button it imports he settings from the left channel to the right channel, so that means you can effectively have two compression profiles, selectable via that switch. You could have one for SSB and another for FM, but in my case I relay a VHF FM net over UHF FM (3 times per week) and the incoming audio levels from the VHF stations are all over the place, so rather than setting it for the quietest one and letting the loud ones be 'massacred' by the radio's (IC 9100) inbuilt limiter (which doesn't sound good), when relaying I toggle that switch to import my 'extreme settings' (ratio 8:1, attack 1 ms, release 0.75 s) and it 'evens up' all the UHF transmissions; it's very cool. Incidentally, I'm using the classic Drawmer DL241 compressor and if you compare a picture of its front panel to the Behringer, their similarity will give you a chortle (the only real difference is that Behringer added a de-esser). Behringer do like to take their influence from some of the classics (same with the Aphex 'Aural Exciter and Big Bottom' - the best product name ever - and Behringer's SX3040). 🙂 🙂 😀
I've just procured myself a really nice (and clean) Aphex Compellor 320A and after sorting out the levels (which I've just finished; I had to carefully pad the Icom's line input as there isn't a huge range on the Aphex's output pot) and it now sounds way beyond awesome on 2m FM. I'm managing to pack lots of [distortion free] audio into the IC9100 (AKA I'm stopping just shy of where its nasty limiter kicks in; you can see that by using SDR Console's mod meter when it 'flat tops' on speech peaks, or even just by hooking up a 'scope on the AF output of any old FM amateur receiver and noting where it stops increasing in amplitude) and all this is now being achieved with no compression artifacts (previously, I was using either the Drawmer's compressor, or my SPL Track One channel strip's compressor, all just to get another 3 - 4 dB of audio 'into the channel' without tickling the Icom's limiter). Now, it sounds a lot cleaner, less fuzzy, and even slightly louder and punchier than it did with either of these compressors, so that's a totally stellar result! I can't wait to hear how it sounds when using SSB; that'll be really quite interesting (we've a VHF SSB net on Wednesday, so I'll hopefully get some interesting - good or bad - feedback from that). 🙂
Excellent video and understandable explanation, George ! I'm currently bidding on one onthat well known on-line Auction Site !
Glad it was helpful!
Nice video for beginers. Thank you it helped me. 👍
Glad it helped
Great nice simple video. Easy to understand Sir.
Thank you, i find your vid is the bestest on the subject
Wow, thanks!
Fantasitic video, best explenation on compresion.
Sory on my bad English.
Glad you liked it!
Muchísimas gracias! Estoy por comprarlo y esto me aclaró un par de dudas!
Nicely done thank you! compressors de-mystified.
Thank you kindly!
Wow! Fantastic video describing how this stuff works. Great job, and thank you!
Glad you found it useful. Cheers.
I think that was very well done.
Thanks so much!
Thanks George, great video. Been spending a lot of time trying to fully grasp the finer points of setting up a compressor, this got me sorted. Got it hooked up to the Ultragain with a SM7b - looking at that gain, guessing it's a similar setup. Cheers!
Glad you liked the video
Great video for this compressor.. thanks mate!
Thanks so much.
Fantastic video. Many thanks.
Glad you enjoyed it
A great helpful video
George
Glad you liked it Rick.
Thanks!!
Welcome!
Great vid
Very helpful... thanks George...
The biggest thing is to understand what all the components do. Best of luck!!!
This was such a good video. Best one out there! Thanks
Thanks so much.
Excellent!!! Great video
Thank you. Glad you liked it.
Thanks man, great video. This is helpfull.
Glad it helped!
Please can this device serve us audio processor in radio studio??
Great video! A couple of things. I think, the button setting on output gain is reverse. Pressed in (lighted) is output. In my view the de-esser knob marking is confusing. It is the level of the automatically detected sibilance frequency. So 0dB means maximum suppression and 10dB is no suppression.
Thanks for the info!
Given that the feature is for reducing excessive sibilance, it doesn't make sense that 10dB be no reduction. The de-esser knob is for controlling the amount of frequency suppression (see p7 of the user manual).
Love it thanks wow
Thank you
how do you hook it up to your mixer ? for ham radio

I want to thank you for these very informative videos. I want to get thay hifi audio as I like to call it. I want 6khz wide on TX.
Motor mouth maul used to make the "Mauldulator" but i dont think he does anymore.
A company called asymod has copied gis work and expanded. They offer several boards for $2-300 American. And will install it for anorher $300 or so.
This is super expensive for me, i want to do direct injection on my president Madison, then run a compressor and noise gate and pre amp.. i believe that will get me the Audio i want. But the Madison is still restricted on gow wide it will TX. Assuming less than 3khz.
Any thoughts?
I've not a clue in the world if the madison would be capable of wide tx. Shoot Tim a mail at snake radio customs in Arizona. Tell gime you were talking to me and ask him. He's done a good few radios for hi fi audio. He may be able to steer you in the right direction.
@@GeorgeEI7KOawesome thank you very much for the response
is it useful for an Electric guitar?
I've seen them used on bass guitar all right.
@@GeorgeEI7KO thank you
nice, thank you
Welcome 😊
Billy 2M0WFN here George _ . _ ! Just bought a Behringer Virtualizer Pro DSP2024P , can I use that for better mic audio too?
You can, but they're complicated enough to set up.
What gear are you using with the 7300?
I have a video on that.
