Cardioid Dynamic Gooseneck Microphone

unipoint® microphones

Architect’s and Engineer’s Specications

The microphone shall be a moving coil dynamic. It shall have a cardioid polar pattern and a frequency response of 150 Hz to 16,000 Hz. Nominal open-circuit output voltage shall be 2.2 mV at 1V, 1 Pascal. Output shall be low impedance balanced (600 ohms).

The microphone shall have an XLRM-type connector at the base for direct connection to a mating XLRF-type panel jack or cable connector.

The microphone shall be an adjustable gooseneck design, with an overall length of 448.0 mm (17.64") and a head diameter of 30.0 mm (1.18"). Weight shall be 278 grams (9.8 oz). Finish shall be low-reectance black.

Features

• Designed for use as a high-quality talk-back, paging & dispatch microphone in entertainment, commercial and industrial applications

• Extremely rugged all-metal construction for long-lasting performance

• Quick-mount design with 3-pin XLRM-type connector insert at base plugs into any standard XLRF-type surface or cable connector

• Low-prole element provides uniform cardioid polar pattern with 120º acceptance angle

• Easy-to-adjust, rugged gooseneck permits quick positioning

• Frequency response tailored for excellent intelligibility in environments with excessive ambient noise

• Cardioid polar pattern reduces pickup of sounds from the sides and rear, improving isolation of desired sound source

• Protective screen reduces wind noise and “popping” when used in close talking situations

U855QL Description

The U855QL is a moving coil dynamic microphone with a cardioid polar pattern. It is designed for use as an extremely durable, high-quality talk-back, paging and dispatch microphone in entertainment, commercial and industrial applications.

The versatile gooseneck design allows for exible positioning and dependable performance. Its custom-tailored frequency response ensures excellent intelligibility in environments with excessive ambient noise. The U855QL stands 448 mm (17.64") from the table or podium.

An XLRM-type connector insert at the base allows the microphone to be plugged directly into an XLRF-type panel jack or microphone cable.

The microphone is enclosed in a rugged housing with a low-reectance black nish.

Installation and Operation

Output 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.

Take care to keep foreign particles from entering the windscreen. An accumulation of iron or steel lings on the diaphragm, and/or foreign material in the windscreen’s mesh surface, can degrade performance.
