MICROPHONE

he MPZ 11 LL WR is a weather-

resistant Pressure Zone Microphone

with balaa nced, ne-level t t. A li ou pu

plastic membrane i ide thns e

microphone protects the mic capsule

from water damage. The mi mounts in a c

standard electrical outlet box. Applications

i l e fast-f d restaurants tdoonc ud oo , ou r

intercoms, tol t , bl boo hs ridges, theme park

security, home aut aom tion, and so on.

The microphone can be pl ed dugg irectly into a

VCR ne input - no cosli tly mic pr mp iea s

needed. Out t (via rew terminals) can bpu sc e

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 fr quency response is ted to helboos p

articulation. Because of s tait ilored response and

PZM constr tiuc on, the PZM11 LL WR will pick up

conversations or other desired sounds with extra

clarity.

The unit is “weather resistant,” ich mwh eans:

• The microphone will work during and after

rainfall.

• The mi s frec’ quency response will change

temporarily i the mef mbrane gets wet, but will

return to normal en dry. wh

• I watef r freezes on the membrane, the mic’s

frequency response will change, t will bu

return to rmal en the ice meno wh lts and the

membrane dries.

• Hi -pregh ssure water sprays directly on the

membrane (thr h the l ered wal plateoug ouv l )

may damage the membrane.

• The microphone is t desi ed to be sub- no gn

merged.

Installation

1. Pl se refer to Fi re 3 and l ate all the paea gu oc rts

shown. The electrical et x and cables aroutl bo e

not inc udl ed.

2. Run a 2-conductor shielded cable to the

surface where you intend to i tall the micro- ns

phone. I tall a stans ndard electrical et outl box

there (2-i h mini m depth). nc mu

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 l aoc tion. Run the power

cable thr h the le in the electrical oug ho box.

Service the end of the power cable.
