The gray SCHOEPS MS-BLM M/S Double Clamp is used for M/S (Mid-Side) recordings with a BLM 3g Boundary Layer Microphone. The larger side of this clamp holds the microphone amplifier (e.g. CMC) or capsule connector of the KC Active Cable, screwed onto the BLM 3g. The smaller side either holds an active cable with an MK 8 capsule or a CCM 8 U compact microphone, which should be placed over the sound inlet of the BLM 3g.
The engraved numeral 8 on the end of the MK 8 capsule or the CCM 8 U compact microphone should lie parallel to the plate of the BLM 3g, and the red dot should point to the left when viewed from behind the microphones.
An advantage of the M/S technique is the ability to easily make adjustments during post-production. The M and S channels can be directly recorded and matrixed into the stereo left and right signals in playback. The apparent width of the stereo image can then be appropriately set for the given situation.
