The GCS-40 is comprised of two separate odd-membrane solid state microphones contained within a single housing. Its capsules are mounted in close proximity on a vertical axis. The upper capsule assembly has the ability to rotate 270 degrees horizontally, relative to the low capsule.

The GCS-40 is the combination of capsule articulation and independent pattern switching which allows a user of the GCS-40 to achieve all manners of coincident pair stereophonic recording techniques. Due to the close proximity of the capsules, there is no phase cancellation resulting from time delay between the two signals. This translates into excellent mono compatibility.

The GCS-40 uses the large (1") odd-membrane capsule. These are independently coupled through low-noise amplifier based on a class A FET driven discrete the OTL balanced output stages. Included with the GCS-40 microphone are a dedicated 5-pin XLR cable, power supply, foam windscreen, special shock-mount and aluminum carrying case.
