Jack contacts should be close to these dimensions.
Operation
The microphone is factory-set for fl at response
at high frequencies. You can raise or lower the
high-frequency response by adjusting "HF ADJ"
on the bottom of the unit.
Typical placement for each microphone is at
arm's length from the user. Place one micro-
phone facing each person or one between every
two people. The front of the microphone is
indicated by an arrow on the bottom of the base
plate.
Press near the center of the switch. The micro-
phone will switch on or off according to how
you set the DIP switches. When the mic is on,
the LED in the housing is lit.
The PCC-170SW includes two keyhole slots in
its base to accept mounting screws.
1. Punch out the keyholes marked on the label
underneath the base plate (use a razor blade,
small screwdriver, etc.).
2. Using the template (Fig. 6), mark the loca-
tion of two holes in the table where you want
to mount the mic. These holes are 1.6-inches
(4.064-cm) apart, center-to-center. They are
2.2-inches (5.588-cm) from the rear of the mic.
See Fig. 5.

Dimensions are to outside of plastic housing.
If your model is the SPP type, install standard
¼-inch (6.35-mm) phone jacks in your table.

Architects' and Engineers' Specifi cations
The microphone shall be the Crown Model
PCC-170SW or equivalent. The microphone
shall be a half-supercardioid electret condenser
type.
The microphone shall employ the principle
of phase coherency achieved by mounting a
small-diameter element very near a boundary,
thus eliminating comb fi ltering in the audible
spectrum. The microphone will exhibit excellent
off-axis response and gain-before-feedback.
A 15-foot (4.6-m), two-conductor shielded
cable with TA3F and A3M connectors shall be
supplied with the microphone. As an option,
the microphone may be obtained with a bot-
tom-mounted stereo phone plug (model PCC-
170SWSPP, no cable provided).
Nominal sensitivity shall be 22 mV/Pa. Maxi-
mum SPL shall be 120 dB SPL for 3% THD.
Equivalent noise shall be 22 dBA nominal. Fre-
quency response shall be 50 Hz to 20,000 Hz
with a uniform off-axis response, over 20 dB
down at the rear nulls.
The PCC-170SW shall have a silent operating
membrane switch which can be confi gured for
push on/off, momentary on or momentary off
operation. The Crown Model PCC-170SW is
specifi ed.
