Crown SASS-P MK II Operating Instructions, Architects’ and Engineers’ Specifications, Warranty

Operating Instructions

Using two 2-conductor shielded microphone ca- bles, plug the microphone into two microphone inputs in your mixing console or recorder. The SASS can be powered with 12-to-48 volt phan- tom power from the console or 9V batteries. Crown makes an AC-powered phantom power supply (model PH-4B) for powering up to four microphones (or two stereo microphones).

To reduce wind noise from air currents or microphone movement, keep the included wind- screen on the microphone. Pull the windscreen over the system from the front, stretching its edges to snap over each of the four rear corners of the boundary plates.

Wind noise and rumble from trucks and air- conditioning can be reduced by switching in the low-cut filter on the rear panel of the micro- phone.

After use, remember to set the rear panel switch to PHANTOM to conserve the batteries.

To avoid a “hole in the middle” effect, mike no closer than 3 feet (0.915 m).

If the perceived stereo spread is too wide, locate the SASS left and right input channels on your mixer, and pan them slightly toward center.

The SASS is designed to have flattest response in a diffuse, reverberant sound field such as in a concert hall. In outdoor or semi-anechoic en- vironments, its response rises at high frequen- cies. In this case, you might want to cut a few dB at upper-mid and high frequencies with your mixer’s equalizers to make the tonal balance more natural.

Architects’ and Engineers’ Specifications

The microphone shall be the Crown SASS-P MK II or equivalent. The microphone shall be a stereo PZM type requiring 12 to 48 volts phantom powering, or two internal 9V batter- ies. A smooth frequency response from 20 Hz to 18,000 Hz shall be obtained in a reverber- ant field. The polar pattern for each channel shall be omnidirectional at low frequencies and unidirectional at high frequencies. Stereo imaging shall be formed by a combination of time differences between channels (caused by spacing the mic capsules) and spectral differ- ences between channels (caused by angling directional microphone boundaries apart). A foam barrier between capsules shall make the unit mono compatible.

The microphone shall have a sensitivity of 6.0 mV/Pa*. The microphone shall accept a 150 dB SPL input while providing no greater than 3% THD typical. The Crown SASS-P MK II microphone is specified.

For more information on how the SASS works and how to use it, please see the Crown Boundary Microphone Applica- tion Guide, available free from your dealer, directly from Crown, or online at www.crownaudio.com > Microphones > Document Libary.
