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 oto 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.
