Dimensions are to outside of plastic housing.

1.On the bottom of the microphone, find 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.

Fig. 6

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 fit.

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’ Specifications

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.

PCC-170

PCC-170W

The microphone shall employ the principle of phase coherency achieved by mounting a small- diameter element very near a boundary, thus elimi- nating comb filtering 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 specified.

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 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 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.
