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. Either place one
microphone in front of each person or one be-
tween every two people. The front of the micro-
phone 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 each mic cable to the input
of a phantom-power supply such as a Crown PH-
4B. For each channel of the phantom-power
supply, connect the output to a mixer mic input.

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" apart, cen-
ter-to-center. They are 2.2" from the rear of the
.900"
mic. See Fig. 5.

3. Screw two #8 woodscrews (.270" 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 fit.
If your model is the SPP type install
jacks in your table. Fig. 7 shows the optimum
jack wiper locations.

Jack contacts should be close to these dimensions.
Architects' and Engineers' Specifications
The microphone shall be the Crown Model
PCC-170 (black) or PCC-170W (off-white) or
equivalent. 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

eliminating comb filtering in the audible spec-
trum. The microphone will exhibit excellent off-
axis response and gain-before-feedback.
A 15-foot (4.6m), two-conductor shielded cable
with TA3F and A3M connectors shall be supplied
with the microphone. As an option, the micro-
phone may be obtained with a bottom-mounted

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 uni-
form off-axis response, over 20 dB down at the
rear nulls.
The Crown Model PCC-170 is specified.
Warranty
Crown professional microphones are guaranteed
unconditionally against malfunction from any
cause for a period of three years from date of
original purchase. Please refer to the enclosed
full warranty sheet for more detail.
Service
If the microphone does not function properly,
check that it is aimed correctly and is configured
and connected as described in this data sheet.
Double check the DIP-switch settings. If there is
hum or no signal, first repair or replace the cable.
If the microphone capsule is defective, order a
replacement PCC-170 mic capsule from Crown
(part no. M43197-9) or return the microphone in
its original packaging to Crown's Service Depart-
ment, Plant 2 SW, 1718 W. Mishawaka Road,
Elkhart, IN 46517. For further assistance or
technical support call 800- 342-6939.
