PCC-170W
1. On the bottom of the microphone, fi nd the hole
labeled HF ADJ. This trim pot adjusts the high-fre-
quency response as shown in Fig. 1.
2. Using the supplied small screwdriver, turn the
pot clockwise for high-frequency boost (a brighter
sound); turn the pot counter-clockwise for high-
frequency rolloff (a duller sound).
Installation
Typical placement for each microphone is at arm’s
length from the user. Place one microphone in
front of 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.
If the microphone is used on a lectern, place it
on an open surface, not in a cavity. Otherwise
the frequency response and polar pattern will be
degraded.
Connect the far end of the mic cable to the input of
a phantom power supply, such as a Crown PH-1A.
Connect the output of the phantom power supply
to a mixer mic input. Or, if your mixer has phan-
tom power built in, connect each mic cable directly
to a mixer mic input.
The PCC includes two keyhole slots in its base to
accept mounting screws. To screw the PCC to a
table top, follow this procedure:
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 location
of two holes in the table where you want to mount
the mic. These holes are 1.6 in. (4.06 cm) apart,
center-to-center. They are 2.2 in. (5.588 cm) from
the rear of the mic. See Fig. 5.
3. Screw two #8 woodscrews (.270-in. [0.686-
cm] dia. head) into the table at the locations you
marked.
4. Loosen the screws enough to receive the mic
and to hold it with a friction fi t.
If your model is the SPP type, install 0.25-in.
(0.635-cm) phone jacks in your table. Fig. 7 shows
the optimum jack wiper locations.
Jack contacts should be close to these dimensions.
To mount a Switchcraft 152B thick-panel phone jack,
drill a 0.5-in. (1.27-cm) diameter hole with a 0.625-
in. (1.588-cm) diameter, 0.125-in (0.318-cm) deep
counterbore.
Architects’ and Engineers’ Specifi cations
The microphone shall be the Crown Model PCC-
170 (black) or PCC-170W (off-white) or equiva-
lent. The microphone shall be a half-supercardioid
electret condenser type, utilizing a subminiature
transducer of rugged construction.
The microphone shall employ the principle of
phase coherency achieved by mounting a small-
diameter element very near a boundary, thus elimi-
nating comb fi ltering in the audible spectrum. The
microphone will exhibit excellent off-axis response
and gain-before-feedback.
A 15-ft (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 bottom-mounted 0.25-in.
(0.635-cm) stereo phone plug (model PCC-
170SPP, no cable provided).
Nominal sensitivity shall be 22 mV/Pa. Maximum
SPL shall be 120 dB SPL for 3% THD. Equivalent
noise shall be 22 dBA nominal. Frequency re-
sponse shall be 50 Hz to 20,000 Hz with a uniform
off-axis response, over 20 dB down at the rear
nulls.
The Crown Model PCC-170 is specifi ed.
Warranty
Crown professional microphones products are
guaranteed against malfunction for a period of
three years from date of original purchase. See en-
closed warranty sheet for additional information.
Service
If the microphone does not function properly,
check that it is aimed correctly and is confi gured
and connected as described in this data sheet.
Double check the DIP-switch settings. If there is
hum or no signal, fi rst repair or replace the cable.
If you determine the microphone product(s) is
defective, order a replacement PCC-170 mic cap-
sule from Crown (part no. M43197-9) or return
the complete product in its original packaging
to: Crown Factory Service, 1718 W. Mishawaka

tance or technical support call 800-342-6939.
