Sanken CUB-01BE


The Sanken CUB-01 overcomes the limitations of previous boundary microphones. Generally speaking, most boundary microphones have almost the same sound characteristics, heard as "thin," "solid," and "metallic." Using Sanken's advanced technology, the CUB-01 has resolved this problem with its unique square-shaped cardioid capsule. This proprietary design significantly enlarges the effective area of the diaphragm, resulting in a boundary microphone whose sound is rich and natural, with a flat response to 70Hz. Now it is possible to capture a "full bodied" and "clear" sound - human narration and dialogue are clearly caught while excluding unnecessary background noise.

Sanken's revolutionary design has also eliminated the artificial need to overdesign the acoustic construction to create cardioid directivity.

Engineered for use in many situations, from TV and film field shooting to broadcast studio production and conference table recording, the CUB-01 departs from the common design of the boundary mic, which typically requires a large, heavy plate. By comparison, the CUB-01 is unbelievably small (32.5mm diameter, 14mm height, 45g weight) and light. Because of its size, it is easy to conceal from the camera, and can be positioned in a variety of environments, for example, attached to the roof of a car with double-sided sticky tape.
