Jack contacts should be close to these dimensions.

Operation

The microphone is factory-set for flat 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.

If your model is the SPP type, install standard ¼-inch (6.35-mm) phone jacks in your table. Fig. 7 shows the optimum jack wiper locations.

Architects’ and Engineers’ Specifications

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 filtering 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 configured for push on/off, momentary on or momentary off operation. The Crown Model PCC-170SW is specified.
