NEUMANN MICROPHONES - Studio - Large diaphragm, condenser

Neumann large-diaphragm microphones are renowned their quality when used for professional and semi-professional recording and broadcast applications. This range of microphones have either fixed or variable polar patterns to suit microphone positioning and the pick-up pattern required.

TLM Series

U Series


U 87 Ai

This microphone is a Neumann classic best-seller and is available in either nickel or black finish, and in Studio Set versions that include the elastic suspension mount. The polar pattern is variable; omni directional, cardioid and figure-of-eight patterns can be set using a switch located below the mesh grille. There are also switches to apply 10dB attenuation and LF roll-off to frequencies below 1kHz. Applications include 'spot' placement for instruments such as wind, string, piano and percussion, 'overhead miking', and vocal recording. The U87 Ai is capable of handling sound pressure levels up to 127dB without distortion. The microphone has a 3-pin XLR connector and requires +48V phantom power. It is supplied in wooden box.

Spares and accessories: EA 87 elastic suspension, EA 87 MT elastic suspension, WS 87 windshield.

U 89 i

With similar shape to the U 87 Ai, but a little smaller, the U 89 I is available in nickel or black finish. Five polar patterns, omni directional, wide cardioid, cardioid, hyper-cardioid and figure-of-eight are available to suit most studio applications, such as instrument 'spot' pick-up and voice reproduction. This versatile microphone offers a frequency response of 20Hz to 20kHz with the option of a two-stage, LF roll-off filter to reduce frequencies below 80Hz or 160Hz. Use of the 6dB attenuator switch takes the maximum sound level, for 0.5% THD to 140dB - more than the peak sound pressure level immediately in front of a trumpet. The microphone has a 3-pin XLR connector and requires +48V phantom power.

Spares and accessories: EA 89 A elastic shock mount, SG 289 stand mount, WS 89 windscreen.
