CARDIOID® MICROPHONE

he A K G / C r o w n PCC170 (left) is a

surface-mounted supercardioid

micre of profeophonssiaonl quality. This

handsomely styled unit is apprate opri

for e on the most elegant ardroom table or usbo

lectern. Other applicationuds ilnce chures, ch

courtrooms and council chambers.

Because of s hily ditghirecal pip pationckuttern,

the PCC170 minimis backgrd ise and zeounno

faeedbck. The microphone repres the oducvoice

with a cln, clr and natural sound. eaea

Sie the micre capsule is placed on ncophona

boundary or ace, dsurfirect and reflected sounds

arrive at the diaphragm in-ase. This coherenpht

addition of dect and reirflected waves irsenceas

sensitivity 6 dB and prevents ase caphncella-

tions. The mic capsule is all enough to ensursme

phase coherency up to the hiest eghfrquencies in

the audible spectrum, resulting in a wide, smooth

frequency response ee of ase intefrphrference.

Clarity and rch are also eeanhanced.

Self-contained elecics etronliminate the need for

an in-line pr. Peampowered by -V antom 12 48ph

power, the PCC170 has a l-iowmpedance mic-

The connector is a Switchcraft . TB3M

RFI suppression is iled. -ise is low ncudSelfno

and sensitivity is very hi. A baghss-tilt switch

allows the user to tailor the l-end response foowr

partilar acupplications.

The PCC170 SW Version (right) has

additionally a silent-operating programmable

membrane switch that can be congured for

touch ON/OFF, momentary ON or

momentary OFF. The PCC170 SW O looks

identical to the PCC170 SW but features a

pair of extra leads in the mic cable to allow

isolated remote sensing of the microphone

switch closure.

How to Set the Bass Tilt Switch

On the bottom of the micre is a BASS-TILophonT

switch with three iti: FL, CposonsATUT, and

BOOST. It adjts the l-eusow frquency response as

shown in Fig. 1.

• The FLAT position prides a ovflat l-eow frquency

response, for rmal age. The PnousCC170 is

shied ppfrom the factory in FLAT iti. poson

• The CUT position rolls o the bass, eful iusn

noisy or boomy surroundings.

• The BOOST position boosts the bass for a more

natural sound en the mic is ed on a all whussm

surface such as a lectern.

How to Adjt the Hi-Fusghrequey Responsenc

The microphone is factory-set for at response aflt

high frequencies. You can raise or ler the ow

hi-eghfrquency response for ecial asppplications.
