Polar patterns SM 69 fet

In addition to the usual directional polar pat- terns: omnidirectional, cardioid, and figure-8, we have added six intermediate positions.

The narrower characteristics suppress sound from the side more efficiently, while the wide-angle polar patterns are especially useful to record large sound sources.

The directional patterns are selected remotely from the po- wer supply unit. Two rotary switches are used to switch between nine different polar patterns for each system.

The rotary switches are mark- ed in color and numbered corresponding to the respective microphone capsule.

The NS 69 i power supply unit is available for AC mains supply.

As a major difference, when compared with the SM 69 fet, the USM 69 has two built-in rota- ry switches. The five polar patterns of both

capsules can be selected at the microphone it- self. Therefore, no special AC power supply units or powering adapters are

necessary.

The two outputs attach di- rectly to any 48 V phantom powered connectors.

In addition to the usual polar patterns: omnidirectional, car- dioid, and figure-8, we have added a hypercardioid and a wide-angle cardioid pattern.

Electrical features

The amplifiers feature high output capability and extremely low self noise. Distant sound sources, as well as very loud sound sources at close range can therefore be recorded without any problem.

Each amplifier has an active filter. It effectively suppresses subsonic interference as caused by wind or structure borne noise. At the same time, the filter prevents the output transfor- mers from overloading through very low fre- quency energy.
