Excuse my bluntness DC but, WTF have you got the speakers plugged into different outlets? Simply put a 'diss strip ' on the quiet speaker's power socket and run a mains extension to the second. Then their grounds are "starred" back to the same mains ground. Dave. I did this Dave. No change. Same ...

Since the YC88 has a three conductor mains connector (IEC type 13) wouldn't you also need to isolate the piano from the control room/mixer? BTW DC, I'm assuming it's a typo but you say "So a proper XLR mic cable should use a three conductor unshielded cable with a cable like: Ground (bare metal ...

They are in different rooms, on different floors, of a large building on the other side of the Atlantic, Dave. Hugh the transformer isolators in the signal path to the Midas in the basement has reduced the hum to zero in the right JBL Eon in the live room. But I use two Eons in stereo, and the left ...

My next problem is that even with the grounds isolated (via transformers) between the upstairs live room and the Midas in the basement control room, one of the JBLs (left) has his and noise present that the other (right does not). The JBLs are plugged into different outlets. I have each of the JBL ...

Try connection the keyboard XLR outputs directly to the console, and the unbalanced quarter-inch outputs via the DTI box, to the JBLs. Does anything hum in that configuration? A DI box should have worked as well (with the ground lift activated) — but only if you used the balanced mic level out to t ...

That should read "XLR mic cables should use a two core shielded cable". Agreed. Otherwise know as a shielded twisted pair — two twisted signal wires within an overall shield. Twisted pair two-ended signal, or alternatively shielding, are both ways to achieve the same goal, canceling of the common m ...

If the equipment is grounded correctly then linking the shell to pin-1 shouldn't make any difference. A lot of (Chinese) commercial cables include that link... but the current AES recommendation is NOT to use a direct link. ...although a capacitor connection is recommended to enhance RF shielding ...

I’ve always wired my xlrs to pins 1,2 and 3, nothing else. I connected up one day with the xlr cable I got from rode with my NT2a and got this kind of noise. Swapping to one of my cables solved the problem so I investigated the Rode cable and found one end had pin 1 shorted to the shell. One snip a ...

#You're too far away from me# Sorry DC I was having a clear out and found a pair of OEP A262A6E "600 Ohm" transformers that I am sure would fix your problem. Not all that way away though! Free if anyone else UK really needs them. Dave. Thank you Dave. Love you man!! 💙🎹🎙 The transformers worked to el ...

And thank you all for your help over the years! You mean a lot to me! And I simply could not do this without you!

This current issue is a total show stopper for my studio and I have a very busy schedule coming up.

I need a plan to fix this up, and I really appreciate your help.

As a first experiment, I'd run the XLR outputs down to your recording rig in a different room, and use the unbalanced quarter-inch outputs to feed your local PA speakers. I am using unbalanced TS cables to feed the JBLs with XLRs going to the Midas. This does not cure the problem. Same hum. But, if ...

I have a Yamaha YC-88 Keyboard connected to JBL Eon active speakers in the live room and it sounds great with no hum. I am using the TRS balanced line outs of the YC-88. The output L and R are 1/4" standard mono phone jacks on the YC-88, i.e. unbalanced. And those are the outputs you are driving ...

It certainly appears to be a ground loop. Is there any hum through the M32? Are you sure that all the wiring to the JBLs is fully balanced? If so, then the JBLs appear to have a "pin 1 problem" as a properly balanced input shouldn't be susceptible to this issue. Negative. No hum in the Midas while ...

Hi, and Thank you in advance for any help you can give me to solve a terrible problem. My new beautiful studio has a very loud hum problem. Something very terrible is wrong and I need your help. I have a Yamaha YC-88 Keyboard connected to JBL Eon active speakers in the live room and it sounds great ...

We are considering this:

Midas M32 LIVE 32-Channel Digital Mixing Console

Has SoS done a review?

I get it now! Analog multicore. Ok so Redco has 24 channel multicore cable. Each core is 2 conductor with shield. So I can use this for each of the 24 balanced connections between live room and basement control room. https://www.redco.com/Mogami-W2936.html I will need to pull it through the building ...

BTW the physical run from the live room to the basement control room is not long. The control room is directly below.

Personally, I'd stick with analogue multicores — maybe three 8-ways to different parts of the room.... if you're sure 24 channels is sufficiently future proof. However, if you're really keen on going modern, I'd recommend RME interfaces and MADI over fibre. Very short latency, more channels than y ...

Oh this looks looks great! I will engage them!! Thank you
