PRESSUREZONE

MICROPHONE

PZM11 (LL)

he A K G / C r o w n PZM11 is a Pressure

Zone Microphone

designed for

security, surveillance, and conference-

room applications. It can be mounted in

the ceiling or wall in a standard

electrical outlet box. Providing excellent

intelligibility, the PZM11 is designed to look

like something other than a microphone so as

not to draw attention.

Like other Pressure Zone Microphones, the

PZM11 utilizes the Pressure Recording Pro-

cess

™

in which a miniature condenser

microphone capsule is mounted very close to

a sound-reflecting plate or boundary. The cap-

sule is mounted in the “Pressure Zone” just

above the boundary, a region where sound

coming directly from the sound source com-

bines in-phase with sound reflected off the

boundary. The benefits are a wide, smooth fre-

quency response free of phase interference,

excellent clarity and “reach,” and consistent

pickup anywhere around the microphone.

In the PZM11, low frequencies below the

voice range are rolled off to reduce pickup of

Specifications

Type: Pressure Zone Microphone.

Element: Electret condenser.

Frequency response (typical): 80 Hz to 20,000 Hz.

See Fig. 1.

Polar pattern: Hemispherical.

Impedance: 225 ohms, balanced. Recommended

minimum load impedance 1000 ohms.

Open circuit sensitivity: 5 mV/Pa* (–46 dBV/Pa).

Power sensitivity: –45.5 dBm/Pa*

air-conditioning rumble. The high-frequency

response is boosted slightly to aid clarity and

articulation.

The microphone connector is a row of screw

terminals for easy installation. The output is

balanced, low impedance, which allows

long cable runs without hum pickup or

high-frequency loss. Powering is via 12 to

48 volts phantom power.

Installation

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

shown.

2. Run a 2-conductor shielded microphone

cable to the ceiling or wall hole where you in-

tend to install the microphone. Install a stan-

dard electrical outlet box in the hole.

3. Run the mic cable through the hole in the

electrical box and through the hole in the

chassis.

4. Service the end of the mic cable.

5. Attach the leads to the screw terminals.

Connect the cable shield to 1, light-colored

lead to 2, and darker lead to 3.

6. Place the chassis over the two long screws.

Using the nuts provided, secure the chassis to

the faceplate.

EIA rating: – 139 dBm.

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: 120 dB SPL produces 3% THD.

Output connector: Three screw terminals.

1 = ground, 2 = audio (hot), 3 = audio (return).

Polarity: Positive pressure on the diaphragm

produces a positive voltage on screw terminal 2

with respect to screw terminal 3.

Operating voltage: Standard phantom power, 12 to

48 volts DC on screw terminals 2 and 3 with

respect to screw terminal 1.

Current drain: 400 microamperes.

Materials: Steel plate and high-impact plastic

capsule holder.

Finish: Off-white.

Net weight: 2.5 oz. (71 g).

Dimensions: See Fig.2.

Optional accessories: A K G / C r o w n PH1A

phantom power supply (1 channel, battery or

AC adapter powered), A K G / C r o w n PH4B

phantom power supply (4 channels, AC

powered).

* 1 pascal = 10 dynes/cm

= 10 microbars = 94 dB SPL.

mic input has phantom power built in, simply

connect the mic cable to the mic input.
