The Schoeps RC 350G Active Extension Tube is designed to be used between a Colette series microphone’s capsule and its amplifier. This provides an unobtrusive way to place a microphone capsule directly in front of a vocalist or announcer without blocking anyone’s view. This type of extension tube is widely used for miking orchestras in television and video productions.

The RG 8 swivel clamps the Colette tube onto a vertical support rod, allowing adjustment of the tube’s height and angle. The angle of the capsule relative to the tube is adjustable independently from 0 (fully extended) to 120°. This gives the Colette tube a very wide range of applications.

Laterally-addressed capsules (MK 4V, MK 41V, MK 4VXS, MK 6, and MK 8, sold separately) can be used on the RC Active Extension Tube with a small elastic ring (included). This ring should be slipped over the threads of the RC so that the capsule can be aimed in the desired direction.

Adjustable Angle 0 to 120°

Q: 1. Mine doesn't seem to work. Tried it with a EF 100mm f/2.8L Macro L series and a Canon EF 16-35mm f/4L. Couldn't get it to focus no matter what I tried. What am I doing wrong?

A: It adjusts your backfocus to allow for a macro image. You will find that with a zoom, you can use your zoom control to help focus - it will change your focal plane. For fixed focal length lenses, you have to physically move to find the distance at which the target will be in focus, almost like you are using a lens with a nearly fixed focal distance. That's because you shifted the lens out of the focus plane
