The U 89* is a studio microphone for universal applications. The headgrille protects a dual-
The amplifier accepts sound pressure levels up to 134 dB without distortion. This figure can be increased to 140 dB. An additional rotary switch activates a filter that changes the low frequency response either below 80 Hz or 160 Hz frequency. ApplicationsThe U 89 i is similar in appearance to the U 87. It is of smaller size, and lighter weight. It features five instead of three directional characteristics and a higher maximum sound pressure level which make this microphone easier adaptable to different applications. Polar patternsIn addition to the usual directional polar patterns: omnidirectional, cardioid, and figure-
As a result the U 89 i has a very even diffuse-
This characteristic is achieved without resorting to corrective resonance effects.
The capsule it is elastically mounted to avoid any structure borne noise that could interfere with its operation. Filter and attenuationThe amplifier handles sound pressure levels up to 134 dB without distortion. With a self noise level of 17 dB (A-
