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 Crown Factory Service,
1718 West Mishawaka Road, Elkhart, IN
46517. For further assistance or technical
support call 800-342-6939.
