serves as a cough button or privacy button.

After choosing the option you prefer, set the DIP switches according to the label on the bottom of the microphone (see Fig. 5). The LED in the microphone housing will light when the mic is on.

If you want the mic to be continuously on (so you can gate it on and off externally), set the DIP switch to “DISABLE MIC GATING.”

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 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.

Solder the shield, green and white leads to an XLR type connector, shield to pin 1, green to 2, white to 3. Plug this connector into the input of a phantom-power supply such as a Crown PH- 1A. Connect the output to a mixer mic input. Or if your mixer has phantom 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.).

Fig. 6

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-inch (4.064 cm) apart, center-to-center.

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.

Operation

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.

If you set the DIP switch to “DISABLE MIC GATING,” the mic is always on. Pressing the

PCC-170SWO

switch will light the LED and activate remote sensing.

The contact-closure leads (red and black) pro- vide remote sensing of mic attenuation. Switch closed (low resistance) is mic ON. Switch open (high resistance) is mic OFF.

To detect when the mic is on, apply a small voltage to the remote sensing leads (Fig. 7). Apply +DC to the red lead and -DC to the black lead. Large voltage and current may induce noise into the audio output. Maximum switch voltage and current are 350 V, 200 mA. On- resistance is 7 to 10 ohms with the included 15-foot cable.

Warranty

Crown professional microphones are guaran- teed against malfunction for a period of three years from date of original purchase. Please refer to the enclosed full warranty sheet for more detail.
