Title: Schoeps UMS20 Isolation question
Post by: MPemulis on July 02, 2026, 02:36:28 PM
Hoping someone can help me out. 

Picked up a UMS20 bar to use with my schoeps MK4 and CMC1s, and am having a hard time figuring out how to use this combination with some vibration isolation.


Anyone have a UMS20 who can shed some light on how I might solve this problem?

I've never owned or used one of these, but it's my understanding that you leave the clips on the bar alone, and suspend the entire thing by its handle in the A 20 S.

[edited later to add:] yes, according to the old, original flyer (see below) that's how they intended it to be done.

The stiffer A20S mount should do a fine job of isolating the entire bar if you add an extension to the bar's mounting screw. This is the same arrangement that I used with my Vark bar and MK41 active mics - clips for the mics and a single shock mount for the bar. The short CMC1 amplifiers shouldn't need to be "crossed over" to get ORTF or other closely spaced arrangements like DINa.

ok, helpful experience/thinking here, thank you. 

I am finding when I try the single A20 mounting the clip/bar, it just initially feels like the mics/bar are too heavy for the suspension, but I will play around with it and if I can get it more dialed in. still think it's weird you can't just add the suspensions where you mount the mics, but just because it's weird doesn't mean it isn't so.
