PRESSURE

ZONE

MICROPHONE

he PZM11 LL WR is a weather-

resistant Pressure Zone Microphone

with a balanced, line-level output. A

plastic membrane inside the

microphone protects the mic capsule

from water damage. The mic mounts in a

standard electrical outlet box. Applications

include fast-food restaurants, outdoor

intercoms, toll booths, bridges, theme park

security, home automation, and so on.

The microphone can be plugged directly into a

VCR line input - no costly mic preamp is

needed. Output (via screw terminals) can be

balanced or unbalanced. Powering is by 12-24V

ACor DC. The unit can be factory-set for phan-

tom powering by special order.

In the PZM11 LL WR, frequencies below the voice

range are rolled off to reduce traffic rumble. The

high-frequency response is boosted to help

articulation. Because of its tailored response and

PZM construction, the PZM11 LL WR will pick up

conversations or other desired sounds with extra

clarity.

The unit is “ weather resistant,” which means:

• The microphone will work during and after

rainfall.

• The mic’s frequency response will change

temporarily if the membrane gets wet, but will

return to normal when dry.

• If water freezes on the membrane, the mic’s

frequency response will change, but will

return to normal when the ice melts and the

membrane dries.

• High-pressure water sprays directly on the

membrane (through the louvered wall plate)

may damage the membrane.

• The microphone is not designed to be sub-

merged.

Installation

1. Please refer to Figure 3 and locate all the parts

shown. The electrical outlet box and cables are

not included.

2. Run a 2-conductor shielded cable to the

surface where you intend to install the micro-

phone. Install a standard electrical outlet box

there (2-inch minimum depth).

3. The PZM11 LL WR can be powered by 12-24V

ACor DC.

From your power source, run a twisted pair

power cable to the mic location. Run the power

cable through the hole in the electrical box.

Service the end of the power cable.

Specifications

Transducer type: Electret condenser.

Frequency response (typical): 80 Hz to 10,000 Hz

(see Fig. 1).

Polar pattern: Hemispherical.

Impedance: 75 ohms, balanced. Recommended

minimum load impedance 1000 ohms.

Open-circuit sensitivity, typical: 1.4 V/Pa.

Power sensitivity, typical: +8 dBm/Pa.

Equivalent noise level (self-noise): 26 dB SPL typical

(0 dB = .0002 dyne/cm

), A-weighted.

S/N Ratio: 68 dB at 94 dB SPL.

Maximum SPL: 100 dB SPL produces 3% THD at

maximum gain.

Operating voltage: 12-24V ACor DC, Phantom

powering by special order.

Polarity: Positive pressure on diaphragm produces

positive voltage on audio+ terminal with respect to

audio– terminal

Current drain: 4 milliamperes.

Operating temperature range: –10 to +60 deg. C, 14

to 140 deg. F. The mic still works at –40 deg. Cbut

its sensitivity is reduced. When the mic is returned

to normal operating temperature, its sensitivity will

be within +/–3 dB of normal.

Output connector: Screw terminals labeled AUDIO+,

AUDIO– and GROUND.

Cable: None supplied. Use 2-conductor shielded mic

cable and twisted-pair power cable.

Materials: Steel plate and high-impact plastic capsule

holder. Plastic membrane, part no. 127255-1.

Finish: Silver. If you paint the mic, take care not to

paint inside the louvered wall plate.

Net weight: 2.5 oz. (71 g).

Dimensions: 4.530 x 2.780 x 1.722 inches (LWD)

(see Fig. 2).

* 1 pascal = 10 dynes/cm

= 10 microbars = 94 dB SPL.
