he MPZ11 LL WR is a weather-

resistant Pressure Zone Microphone

®

with balaa nced, ne-level tt. A lioupu

plastic membrane iide thnse

microphone protects the mic capsule

from water damage. The mimounts in a c

standard electrical outlet box. Applications

ile fast-fd restaurantstdooncudoo, our

intercoms, tolt, bl boohsridges, theme park

security, home autaomtion, and so on.

The microphone can be pled duggirectly into a

VCR ne input - no coslitly mic prmp ieas

needed. Outt (via rew terminals) can bpusce

balanced or unbalanced. Powering is by 12 24-V

ACor DC. The unit can be factory-set for an- ph

tom powering by special order.

In the PZM11 LL WR, frequencies below the voice

range are rolled o to reduce trac rumble. The

hi-egh frquency response is ted to helboosp

articulation. Because of s taitilored response and

PZM constrtiucon, the PZM11 LL WR will pick up

conversations or other desired sounds with extra

clarity.

The unit is “weather resistant,”ich mwheans:

• The microphone will work during and after

rainfall.

• The mis frec’ quency response will change

temporarily ithe mef mbrane gets wet, but will

return to normal en dry. wh

• Iwatef r freezes on the membrane, the mic’s

frequency response will change, t will bu

return to rmal en the ice menowhlts and the

membrane dries.

• Hi-preghssure water sprays directly on the

membrane (thrh the lered walplateougouvl )

may damage the membrane.

• The microphone is t desied to be sub- nogn

merged.

Installation

1. Plse refer to Fire 3 and late all the paeaguocrts

shown. The electrical et x and cables aroutlboe

not incudled.

2. Run a 2-conductor shielded cable to the

surface where you intend to itall the micro- ns

phone. Itall a stansndard electrical et outlbox

there (2-ih minim depth). ncmu

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

ACor DC.

From r power source, run a twisted pair you

power cable to the mic laoction. Run the power

cable thrh the le in the electrical oughobox.

Service the end of the power cable.
