Blue B4-CAPSULE Perspex Sphere Pressure Omni Small Diaphragm

The Big Omni.

The B4 represents our finest craftsmanship, evoking an ethereal quality sought after by producers and engineers alike. The Perspex sphere which houses our small diaphragm capsule, hand-built by BLUE engineers, is a unique design made popular in the 1950’s on the RCA Red Seal series recordings. For room sounds and ambient drum recording, nothing parallels the sound of this capsule.

The B4’s sweet highs are never harsh or strident, and the bass response below 120 Hz is unusually robust for an omnidirectional microphone. This capsule’s smooth presence lift conveys an extra measure of high end detail and focus, preventing distant sounds from becoming overly diffuse or “washed out”. I call this the audiophile capsule; traditionally Perspex sphere microphones are highly regarded for distant miking of classical instruments and ensembles. And, along with the B0 and B2 capsules, the B4 offers maximum low-end pickup, ranking as a particularly useful and unique tool for studio recording. Expect some ambient pickup of low end noise (air conditioning, rumble etc.), and 4 to 8 dB lower output relative to other capsules.
