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 fi lter 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 fl attest response 
in a diffuse, reverberant sound fi eld 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’ Specifi cations

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 fi eld. 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 specifi ed.

Warranty

Crown professional microphones are guar-
anteed against malfunction for a period of 
three years from date of original purchase. 
See enclosed warranty sheet for additional 
information.

Service

If the unit fails to work, fi rst replace or repair 
the mic cables, check batteries, and check the 
power supply. A Service Return Authorization 
(SRA) is required for product being sent to the 
factory for service. An SRA can be completed 
on line at www.crownaudio.com/support/fact-
serv.htm. If service is required, return the 
microphone and the electronic interface in the 
original packaging to
