CARDIOID CONDENSER

HANGING MICROPHONE

- Designed for suspension over choirs,

instrumental groups and the theater

stages.

- Superior off-axis rejection for maximum

gain before feedback.

- UniGuard™ RFI-shielding technology offers

outstanding rejection of radio frequency

interference (RFI).

- UniSteep® lter provides a steep low-

frequency attenuation to improve sound

pickup without affecting voice quality.

- Accepts interchangeable elements to

permit angle of acceptance 90° to 360°.

- Low-prole design with low-reectance

nish for minimum visibility.

- Available in two colors: black (U853A / U853R) and white (U853AW /

U853RW).

The U853A requires 11V to 52V DC phantom power or a 1.5V AA battery for

operation. A battery need not be in place for phantom power operation.

Alkaline batteries are recommended for longest life. Remove the battery

during long-term storage.

The U853R requires 11V to 52V phantom power operation only.

A uniform 120° angle of acceptance provides well-balanced audio pickup.

The microphone should be located forward of the front-most source, above

the rear-most source, and "aimed" between them (Fig.1). Increasing the

height of the mic above the sources will tend to equalize sound levels

between them, but may also increase from the mic to the rear-most pickup

should be no more than twice the distance to the front source, to maintain

front-to-rear balance (Fig.1).

Width of pickup is approximately three times the distance to the closest

performer. If additional mics are needed for wide sources, they should be

positioned apart laterally at least three times the distance to front source, to

avoid phase cancellation (Fig.2).

To orient the microphone in the proper direction, twist the housing slightly

in its wire holder. (Clockwise rotation moves the microphone to the right;

counterclockwise rotation moves it to the left.)

Output from the power module's XLRM-type connector is low impedance

(Lo-Z) balanced. The signal appears across Pins 2 and 3; Pin 1 is ground

(shield). Output phase is "Pin 2 hot" - positive acoustic pressure produces

positive voltage at Pin 2.

At integral 80 Hz high-pass UniSteep® lter provides easy switching from a

at frequency response to a low-end roll-off. The roll-off position reduces the

pickup of low-frequency ambient noise (such as trafc, air-handling systems,

etc.), room reveberation and mechanically coupled vibrations.

Avoid leaving the microphone in the open sun or in areas where trmperatures

exceed 43°C for extended periods. Extremely high humidity should also be

avoided.
