The headgrille protects a dual-diaphragm capsule. A rotary switch below the headgrille selects from five different polar patterns. Therefore the microphone can be adapted easily to large sound sources, and those that are spread wide apart, or to sound sources to be recorded at a greater distance.\u003c\/p\u003e\r\n\u003cp\u003eThe 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.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eApplications\u003c\/strong\u003e\u003c\/p\u003e\r\n\u003cp\u003eThe 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.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003ePolar patterns\u003c\/strong\u003e\u003c\/p\u003e\r\n\u003cp\u003eIn addition to the usual directional polar patterns: omnidirectional, cardioid, and figure-8, we have added a hypercardioid and wide-angle cardioid characteristic. When compared to the standard cardioid pattern, the hypercardioid characteristic suppresses sound from the side more efficiently. The wide-angle polar pattern is especially useful to record large sound sources.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eAcoustic features\u003c\/strong\u003e\u003c\/p\u003e\r\n\u003cp\u003eThe microphone is addressed from the front, marked with the Neumann logo. The large diaphragm capsule has a very smooth frequency response for all polar patterns over a wide acceptance angle. The frequency response curves are flat up to 10 kHz within a pickup angle of ± 100°.\u003c\/p\u003e\r\n\u003cp\u003eAs a result the U 89 i has a very even diffuse-field response for all polar patterns. This is important in a reverberant environment when more reflections arrive at the microphone capsule. The acoustic information is not affected in its tonal quality when recorded by the microphone.\u003c\/p\u003e\r\n\u003cp\u003eThis characteristic is achieved without resorting to corrective resonance effects.\u003c\/p\u003e\r\n\u003cp\u003eThe capsule it is elastically mounted to avoid any structure borne noise that could interfere with its operation.  \u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eFilter and attenuation\u003c\/strong\u003e\u003c\/p\u003e\r\n\u003cp\u003eThe amplifier handles sound pressure levels up to 134 dB without distortion. With a self noise level of 17 dB (A-weighted) the total dynamic range is 117 dB. Maximum sound pressure level is 140 dB when the - 6 dB rotary switch is in the ON position.\u003c\/p\u003e\r\n\u003cp\u003eA low frequency roll-off at 80 Hz or 160 Hz can be activated with another rotary switch below the headgrille. This filter suppresses low frequency interference, yet maintains an even frequency response for close-up sound sources, for example, when proximity effect could adversely affect the program material.\u003c\/p\u003e\r\n\u003cp\u003eA steep high-pass filter in the LIN position prevents the output transformer of the microphone from being overloaded due to undesired subsonic frequencies.\u003c\/p\u003e\r\n\u003cp\u003e\u003cstrong\u003eOperational safety\u003c\/strong\u003e\u003c\/p\u003e\r\n\u003cp\u003eAll exposed surfaces of the microphone capsule, including the diaphragms, are at ground potential.
