Microphone Mechanics: Specifications for Stands, Fixtures, and Attachments

This article is about the physical equipment required to place professional microphones on stage for a live performance or in the studio for recording. Electrical and signal considerations are not our concern here. What we care about right now are the mechanics of securely and reliably positioning a microphone in front of a sound source. This is about bases, stands, booms, thread adapters, clips, and shock mounts.

Microphone Stands


  • Solid
    • Round
    • Nesting/stackable
  • Tripod
  • Mobile/rolling


5/8 Tubing

  • Outside Diameter: 5/8 inch (0.625 inch)
  • Threading: #27, i.e., 27 tpi (threads per inch)

7/8 Tubing

Typical for mic stand bases.

  • Outside Diameter: 7/8 inch (0.875 inch)
  • Threading: #27, i.e., 27 tpi (threads per inch)

Microphone Fixtures

Among the most common microphone fixtures is the 5/8 male to 3/8 female adapter. This item is often supplied with SM-57 style microphone clips and is notorious for getting stuck inside those same clips.

Thread standards for microphone fixtures:

  • 5/8 inch – 27 TPI – USA standard
  • 1/2 inch – 12 TPI (apparently found in older European stands and/or microphones)
  • 3/8 – 16 TPI European Standard (While not a standard fitting specification in the US, adapters are readily available and are often provided with microphone clips. The UNC equivalent is used for heavy camera equipment in photographic fittings).
  • 1/4 inch – 20 TPI (BSW) compatible with UNS, a US standard common in photographic fittings, e.g. tripods.

Microphone Clips

  • Spring-loaded clips
    • Octava style
  • Snap-fit clips
  • Compact shock clips

Microphone Shock Mounts

  • Elastic band
  • Rubber fitting
  • Articulated (lyre)

Microphone Fixture Arrangements

  • Stereo Bar
  • X-Y
  • ORTF
  • Mid-Side
  • Blumlein
  • SM57 + SDC
  • SM57 at 45°

Letterpress and Type Casting Items for Sale

The time has come for me to downsize my letterpress shop. I have too much equipment in my tiny shop and not enough space left over to pursue my varied creative interests. I still intend to maintain a print shop, but on a reduced scale.

While I have both printing and typecasting items on offer, this could be a particularly good opportunity for someone within driving distance of Lititz, PA to start or augment a small type foundry—as I’ve done you the favor or collecting high-quality Monotype equipment from all over the place. Or, to put it differently, a local sale would be very convenient for you and for me!

I’ll post inventory and asking prices here. In the meantime, here’s a run down of the key items…

Type foundry equipment.

  • One late-model British Monotype combination casting machine with unit-shift, unit adding, quadding and centring, display attachments, lead and rule attachment. Fully operational machine with electric melting pot and varigear drive from the famous Woodside Press in Brooklyn.
  • One rebuilt, late-model  British Monotype composition casting machine with display attachments. Fully functional machine with electric melting pot and varigear drive from the respected Heritage Printers in Charlotte, NC.
  • One British Monotype composition casting machine with electric pot and heavy gearbox. This unit came from the renown Mouldtype in the UK. Needs some work to be fully operational, but is complete.
  • Complete set of spare parts—enough to maintain the three good machines and still have enough left over to build a new machine from parts (well almost!).
  • Monotype composition keyboard.
  • A wide selection of keybars, stopbars and wedges.
  • All parts necessary to cast type from both Lanston (American) and Britsh monotype matrices (including a spare Lanston bridge, as well as virtually any type of foundry matrices. Several custom parts fabricated by Theo Rehak of the Dale Guild, who learned his craft at ATF.
  • All original Monotype tools: wrenches, spanners, pump piston extractor, microscope, spool winder, gauges. thermometer
  • Five gallons of original Monotype mould oil. (Really! It’s a lifetime supply.)
  • Moderate selection of casting matrices.
  • A few pigs of clean type metal. Couple hundred pounds of pi ready for remelt.
  • A mountain of documentation and manuals from 1916 though the 1980s.
  • 1930s Deckel pantographic engraving machine. Needs some work to be operational. (I was learning how to cut my own matrices, but just don’t have the time for it right now. SOLD.

Print shop equipment:

  • Chandler & Price ‘New Style’ 12 x 18 platen press. Belt-driven with 1 HP Kimble motor. Very clean and well maintained. Includes pony inker, three chases, 1 set of good rollers, spare set of roller cores.
  • Small Imposing table. Home-made but just right for this press.
  • Rouse Vertical Rotary Miterer
  • 19″ Morgans & Wilcox guillotine gutter
  • Kelsey Model U 5 x 8 hand platen press – like new, but rollers need recovering. Two chases.
  • CB Nelson Cost Cutter Model C printer’s saw.
  • Various hand tools of the trade.
  • Several sets of furniture and quoins suitable for small and large presses up to 12 x 18 or larger.

New Full-length Album from A Private Press

I’m proud to announce the release of the first full-length album made with my cohort, Nicola Dixon. After years spent working together in various indie-rock outfits, we set our sites on a different sound — something sincere, beautiful and sparse, but still richly textured. That effort resulted in a band called A Private Press, and an debut album called Risky. Imagine a very pure female vocal and lush electric guitar weaving curious tales of personal progress and change. Smooth, witty and biting, delivered on a human scale. We hope the album rewards the listener on multiple levels. Better yet, don’t imagine it. Listen to it.

My Band’s New EP Released

Listen to it. Buy it.

Goldbrick highlights Smiles, Everyone’s spirited command of art-rock theory and power pop punch. Jangly guitars layered over deft basslines and disciplined percussion create perfect structures for Nicola Dixon’s expansive vocal range and exquisite storytelling. Thematically, Goldbrick celebrates the awkward duality of living with a briefcase in one hand and a guitar case in the other. Smiles, Everyone capture this notion beautifully in their latest single Debbie Harry, an addictive, catchy gem that sets the pace for this impressive EP.

A New Wood Engraving – First Proof

This is the first progress proof of a small engraving I’ve been cutting this week. There’s still much work to be done, but the composition and tone are beginning to emerge. At the moment, the grain elevator in the background appears to be thatched. That will need to be refined.

The scene is not real. It was drawn from a model that I composed with N-scale (1:160) structures – ones normally used for a model railroad.
