T-67 Capsule Installation Instructions

K67 Capsule Anatomy

K87 Capsule Part Names

These instructions will be more useful if you know what the parts of the capsule are called. See the image at right.

The K67 capsule has two brass backplates.

Screwed to each face is a 34mm diameter clamping ring. The clamping rings hold down the outer edges of the diaphragm, which is a very thin sheet of plastic film, metallized with gold. The diaphragm is also called the membrane.

Which Side Of The Capsule Is The Front

Q: Which side of the capsule is the front diaphragm?

A: Either side can be front; both sides sound the same. After you've installed the capsule, the diaphragm facing the front of the microphone becomes the "front" diaphragm.

Q: One of the clamping rings has a colored mark on it. Is that the front side?

A: Either side can be front; both sides sound the same. After you've installed the capsule, the diaphragm facing the front of the microphone becomes the "front" diaphragm.


Never do this!

Hold the capsule by the edge only. Do not touch either diaphragm.

If you saw this warning after touching the diaphragm: your capsule is not ruined. Fingerprint oil deposits are not audible.

If you punctured or stretched either diaphragm, resulting in holes or wrinkles, the capsule would need to be replaced.


Install the Supersaddle

Remove the curved black plastic saddle that is pre-installed in the T-67 chassis. Retain the screw.

We recommend putting drop of Loctite™ on the threads of the screw that holds the saddle to the mounting post or pedestal, to prevent the saddle from working loose during a session.


Install the "supersaddle" that is packed with the T-67 capsule, using the screw removed previously. The alignment tabs on the bottom of the saddle should fit into the slots in the mounting post.

For the T-67, the supersaddle does not have a "front" or "back" orientation; it will work in either orientation, so long as the alignment tabs are inserted into the mounting post slots.

Over-tightening the screw will snap the supersaddle into two pieces. The screw should be snug, but need not be torqued down.


Mount the new capsule

Mount the capsule to the saddle using two of the included machine screws. Use the outer pair of holes in the supersaddle.

Do not use Loctite or thread sealer on the capsule mounting screws; they might ruin the capsule.

Do not over-tighten the capsule screws; you risk shearing the head off of the screw.
