Main Features

BETA 181/BI (bidirectional) for mono drum overhead, dual instrument sound source applications
Wide dynamic range for use in high SPL environments
Side-address form allows for discreet positioning in tight performance and recording settings
Innovative locking ring provides a secure connection between capsule and preamp
Compact design, under 12 cm (5 in.), reduces stage clutter
Bidirectional Capsule

The Shure Beta 181 is an ultra-compact, side-address, condenser microphone, designed for discreet placement in live and studio environments. Featuring interchangeable capsules for superior versatility, the small diaphragm of the Beta 181 provides superior audio with consistent, “textbook” polar responses in a form factor small enough to get close to the source in the tightest conditions. The Bi-directional capsule can be used for mono overheads, or for the recording of two instruments simultaneously on one channel.
