I knew it was noisy when i bought it and i dont mind the noise but i just saw a morley mhe hum eliminator for cheap and im wondering if i put this between the bx and the mackie (i use it as a summing mixer for drums and the master output is then sent to two channels in my mackie) it would tone the noise down a bit, completely or none at all. Has anyone tried anything like this?
does it look like this?

As a brand, Morley has a better reputation, but the less expensive brand one I tried (attempting to get rid of a ground loop) didn’t help at all. I would make sure it’s a grounding issue before you even try this, because that’s all that this type will help with. If there’s an internal issue, it won’t fix it and the morley is expensive. If it’s not this type specifically, I can’t really comment but I think I know what you’re talking about.
Nope, its this one https://www.morleyproducts.com/hum-eliminator/
You’re talking about the noisefloor of the mixer? I don’t think a hum eliminator/isolator can do anything, but might be wrong…or is it a ground loop?
I’m a bit surprised the BX-16 is so noisy, my BX-8 is pretty silent.
You can try a noise gate to cut the noise when no signal is present.
Actually just found the manual gor that morley, and it seems that it might work for what i need
@Schnork is probably correct, that will work for ground loop as an in-line solution, but it might make for loss of gain. But that’s only if the issue is with ground loop noise. Let us know what happens either way, the Morley looks like a nice unit.
You could try this as a $10 solution to the same problem, it won’t work quite as well and will definitely have some loss of gain (I have these and it does work for ground loop, but I experience loss of gain) however, if this works then you’ll confirm that the morley will do what you expect it to, as it has the same basic function. That way you’re only ten bucks into it before you spend on a better solution.
You could also try a different outlet in a different room before buying anything, if there’s a ground issue it won’t necessarily be in all rooms, a lot of times (if it’s a house) there’s a different path to ground in different rooms. If it’s an apartment with dirty power you might be SOL.
Don’t use the FX send/return, for one. it’s the noisiest part of the BX mixers I’ve found.
If you are only using this mixer to get the delicious overdrive, what I ended up doing is using a smaller BX600 and just running the mix I want to distort through it and blend with the dry signal. Like on an aux send of a mixer, for example.
Will this still work if the hum is coming from the transformer and bleeding into the audio signal path though?
Have you looked at the audio cables your using (balanced/unbalanced)
Yep, i also checked all channels in both mixers, etc. I havent tried using the tape i/o’s yet so im gonna give that a shot, but my guess is its just a high s/n ratio as this model is well known for being noisy
Im using it to glue together all my drums/sub freq. It gives it a nice fat low end compared to the mackie
good luck. my only other suggestion if you don’t want the noise it brings is to keep everything pretty low in the mixer… but im not sure you’ll get the character you want out of it without pushing it, and in my experience you can’t push it without getting the noise. That and avoid the send/return cuz THAT is even noisier!
Oh i figured out the sends on the first day i had it! Lmao
