Where do you notice the gain loss? It's an attenuator, so unless the volume pot when wide open is absolutely zero ohms, it's going to reduce gain. That's what it's supposed to do, no?

What happens when the pot is wide open? (it's probably not zero ohms wide open - but I haven't measured mine. I have a stepped pot on mine.)

Yeah my one is stepped also, I am not a tech but it would be great if it wasn't losing almost 10db of gain on the output.

My nonsteped version does this to.
AFAIK the reason for this is, that the McOne is not symetrical and only using one side of a incomming symetrical signal.

You are losing 10db when you have the volume pot wide open?

Switched my Focal Twins to -10db setting and problem solved :-) This a great cost effective passsive monitor controller and I have had a custom faceplate made and mounted into my console. Good work Evgeny.

Members have any first hand experience with this line passive controller?

"Palmer" MONICON vs McOne?

PMONICON Palmer PRO MONICON - Passive Monitor Controller

I don't know the "Palmer" MONICON, but:

MONICON: 1 in / 1 out (with a second nonselectable output)
McOne: 3 ins / 3 outs

So IMO they are totaly diffrent animals.

Yes you are right!

I want know (quality sound).
Who best?

It seems that it's the best inexpensive one to go. I just read the page and it's said (The McONE is Unbalanced internally). Do I have to worry about it if I run everything balanced?

We have sold tons of these and thus far one person had a grounding scheme that didn't work out with the unit and simply sent it back. My answer is don't worry about it but if it was an issue, you would be taken care of!

War

I run balanced with my McOne and have had zero issues. It is sooo clean!

Wow...

First of all, it just sounds great. I mean it doesn't have sound!!!

Shipping is so fast and it just took a week from Israel to South Korea.

I have to get the McTwo for my main rig!!!

Thank you Evgeny!!!

Tae...

I experience the same thing but only with more than 1 pair of speakers connected. How did you solve it?

Hi!
I've had the McONE for a year now and its great. When I got it I tried listening for tonal differences from inserting this unit in the monitor signal path and I could not tell the difference.
However my NS10s had a small amount of noise when the output selector was set to my other set of monitors - KRK Rokit5s (please don't lynch me if you don't like these monitors its what I could afford as a student). I guessed thats something I was doing wrong but didn't bother me. I would turn off the amp when I was using the other monitors (Hafler amp without a fan hence its in reaching distance).
Recently though my office allowed me to borrow a pair of Adam A8X monitors and I got them home and since I didn't have the cables to hook them up to my McONE, I connected it using microphone cables to my RME Babyface and it was loud.
However once I got the cables and hooked it up to the McONE I noticed there was a significant drop in levels. The KRKs and NS10s were hooked up using stereo 1/4" connector cables. Only the Adams were hooked up using XLR cables. Maybe thats something. So I decided to do some testing and this is the test I ran. Thankfully the RME Babyface has some great features.
On Logic I loaded up the Test Tone plugin and played a sine wave (lower frequencies were less painful) and then on the RME flipped the phase of one channel and set the McONE to mono mode (phase cancellation). As I turned up the volume I could faintly hear the sine wave. But at various points there would be more cancellation. Like the second from last marking had more cancellation. Phase flipped the other channel and got the same results. So i don't think it was the cables.
So I hooked up the monitors to the RME directly and did same test and it was quiet. Perfect cancellation. I guess digital summation was perfect.
Maybe there are some variables I'm not considering hence the difference but it left me thinking. If anyone knows why I'd love to know. It does not however affect my workflow. I still use the McONE and love it. My work doesn't require that kinda precision, I think.

Pretty typical to get some crosstalk in ganged analog channels.

You will get some drop in level unless a volume pot is straight wire when it is wide open.

Thanks a lot!

I will explore those parameters.

Hi I have a McOne stepped and getting a crazy crazy buzzing from it like the unit hasn't been grounded, to the point I can't even use it now. :( It's also mega quiet which makes me feel I have a faulty unit. I have to turn it up to max to have the normal level I work at.

Does anyone else have any issues like this? I'm so gutted as the build quality of this unit is second to none.

I'd love some comparative comments of:

Palmer Monicon <-> NOS McOne
McOne Active <-> Palmer Monicon L

Comments from NOS themselves would be equally useful, as I'm sure they are aware of competing products. Thanks.

I've had mine (passive, variable pot, not stepped) for at least a year now. I ordered mine directly from the builder in Israel so I could get it customized. I had him replace the 'mute' switch with a stereo image reverse switch. I use it all the time to make sure my mix isn't getting too heavy on one side, or to see if the snare drum moves when I flip the image. I also use the mono switch a lot. There was no extra charge for the mod, but I had to wait a few weeks to get it.

Perhaps my own quest for the same can be helpful to you: What monitor controller for home studio?

Towards the end of that thread, I do a review of sorts of the Monicon L.

Good luck hunting!

Digital switching between 6 inputs -- two separate outs .....been the heart of our monitor control for our system, for 20 years ... Wish it was partially XLR ~ balanced I/O . Very clean/ affordable controller ..

I got the McOne-B from a store a 2 weeks ago, but only could install it this weekend. The stereo image shifts to the left when I'm turning it almost all the way down and the mono/stereo switch makes a loud click when I use it. Is this normal behaviour with the mono/stereo switch?

Stereo drift is common with non-stepped attenuators, most noticeable down at the bottom of the range. I have a stepped Alps pot in my McOne and it's matched all across the range.

Easy swap if you are inclined.

Hello, what is the reference of the stepped alps original used in the mcone?

I've got the unballenced unit without stepped.
