Operating Instructions

Unbalanced operation: If you are using a phantom power supply that does NOT include an isolation transformer, and you desire an unbalanced output, use pin 2 as hot and pin 1 as ground. This proce- dure prevents distortion in the PCC circuit. Do not unbalance the output of the supply by connecting pin 3 to pin 1. If you are using a phantom supply containing an isolation transformer (such as the Crown PH-1A AC/Battery Supply), then you can unbalance the output by connecting pin 3 to pin 1 in the cable feeding the mixer. This results in 6 dB more sensitivity.

The PCC includes two keyhole slots in its base to accept mounting screws. To screw the PCC to a surface, refer to Fig. 4 and Fig. 5.

Note: The porous foam liner in the housing must go toward the front of the microphone; the dense foam liner goes toward the rear. Otherwise the frequency response and polar pattern will be degraded.

Placement suggestions for the PCC-160 are in the Crown Boundary Microphone Applications Guide and Speech Sound Reinforcement Application Guide, available online at http://www.crownaudio. com/mic_web/mic-library.htm.

BASS TILT SWITCH: On the bottom of the micro- phone is a bass-tilt switch which allows the user to tailor the low-end response for particular applica-

tions. In general, use the FLAT position. Use the CUT position to reduce room rumble and air-han- dler noise. Use the BOOST position to compensate for low-frequency losses when the PCC is placed on small boundaries such as lectern shelf-tops.

Architects’ & Engineers’ Specifications

The microphone shall be the Crown Model PCC-160 (black) or PCC-160W (off-white). The microphone shall be a half-supercardioid electret condenser type, utilizing a subminiature trans- ducer of rugged construction. A smooth frequency response from 50 Hz to 18,000 Hz shall be ob- tained, with a uniform off-axis response, over 20 dB down at the rear nulls. The microphone will exhibit excellent off-axis response and gain-be- fore-feedback.

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. A 15-foot (4.6-m), two-conductor shielded cable with TA3F and A3M connectors shall be supplied with the microphone.

The microphone shall have a sensitivity of 22 mV/Pa*. The microphone shall accept a 120 dB SPL input while providing no greater than 3 percent THD (open-circuit termination). Equivalent noise shall be 22 dBA typical. The Crown Model PCC-160 is specified.
