Topic: Low profile shockmount for ~17-18mm mic bar

[Brian Skalinder]

Anyone know of a shockmount suitable for an approximately 17-18mm mic bar supporting my low profile Franken Nak mic bar?  (Don't have any calipers handy to perform a precise measurement.)

The ones with which I'm familiar and used by others for a variety of mounting options, only one of which is definitely suitable for my needs:

13-54mm  |  Audio Technica AT8415
19mm  |  Shure A53M
20mm  |  Schoeps A20 (S)
22mm  |  Joe Meek JM-27SM (Schoeps lookalike)
22mm  |  Busman (Schoeps-lookalike, don't know what make / model)
25mm  |  Shure A55M

Right now I'm leaning towards the AT8415.  I'm guessing the A53M is a little too big, but don't have one on hand to try.  And the Schoeps-lookalike is definitely too big...even with extra padding in the shockmount cylinder, the opening of the tube is too wide and not secure enough.

Any other candidates of which I should be aware?

Only thing I can think of that you havn't mentioned is the Rycote INV-6. The bar I use with my beyers is 17-18mm (all I have is a ruler) and it fits well with it. My only concern would be weight. If you'll remind me this weekend I'll put everything together and weigh it.

Not sure if it is Low Pro....but I find this one to be truly versatile (and reasonable in cost), have 2 that have been used for everything from Nak CM100-CP4 Guns to AT853's

You can get slightly heavier O-Rings if you are concerned about weight.

There are a couple different Schoeps A20s lookalikes. There's a Joe Meek shockmount, Busman shockmount and there might even be one more I can't remember. Not sure if the Busman mounts are still in production or not.

Thats the A53. The rycote inv-6 can handle stuff smaller then the A53, down to maybe 16mm if you don't put much torque on the bar. With my bar, I have to add a good 4 layers of taper to get it snug in the donut compared to the clamp-style of the inv-6.

I'm all for the A53M if it actually accommodates 17-18mm -- especially since it's built to hold fairly heavy mics (the SM94 is 9 oz + battery).  Unfortunately, the spec per Shure is 19.05 mm (3/4"), and I don't know how much tolerance is built into the design.  The A26X are "about 11/16 in", or ~17.5 mm, per Shure.

Does anyone have an A53M and a 17.5 mm rod to check?  The Atlas 5/8" F-F coupler is nearly the same size as the Shure A26X (the coupler is just a fraction of a mm larger), so if the coupler fits, I suspect the A26X will fit.

Worst case, I'll go with the AT8415, but I like the compact size of the A53M.  Maybe wrapping the A26X in heatshrink tubing or some such would fill it out enough to fit the A53M.

The best I can measure with ruler is 22mm on the shure donut. I use  mine on a typical mic stand extension tube (about 4 1/2 " long) with audix micro clips on the end to hold the AT 853's. The tube diameter is about 17mm. For a firm fit i simply built the tube up with electrical tape. The chrome tube needed to be masked anyhow.

You'll need to pad the rod a bit if you're final size is just under 18mm, I've tried.

with four bands on each side should hold it

Rycote INV 7 are spec'd to fit 19 - 25 mm | The lyre supports are spaced further apart than the INV 6.

What about a Windtech SP-20?  The wider end is about 19 mm (I assume the 20 in SP-20 stands for 20 mm) and the narrow end is 17 mm.

^This, or the Superlux HM-32 (lighter) will do the trick.  You could use two mounts side-by-side for when the widest setup is used.  The extra bands will hold the bar in place but also allow for rotational flexibility.  This is the method I use on my DIY mount for my mod 700s.

This is probably the best option.

The INV-7 has three mounting points - it is delivered as standard at the widest setting.  The narrow setting is the same as an INV-6 and there is also an intermediate setting.

All you have to do is to unscrew one of the "Lyres" and screw it into the spare hole.
