 SASS-P MK 

II

 Stereo Ambi-

   ent Sampling System™ is a patented,     
   stereo condenser microphone using PZM

®

  

technology. It is a mono-compatible, near-coin-
cident array designed for professional applica-
tions including:

   classical-music recording (acoustic en-
sembles)

   stereo electronic news gathering (E.N.G.)

   sports ambience and crowd reaction

   recording worship services

   televised theatre and dance

   fi lm ambience

   stereo sampling for keyboards

   stereo sound effects

   recording studios and live sound

Compared to its predecessor the SASS-P, the 
SASS-P MK 

II

 provides a warmer, smoother 

sound with more high-frequency brilliance 
(“air”) and less midrange “hardness.”

A patented design

, the SASS

®

 uses a

 

premium-quality Pressure Zone Microphone

®

 

for each channel. The PZMs are mounted on 
boundaries (with a foam barrier between them) 
to make each microphone directional. 

The carefully controlled polar patterns and 
human-head-sized spacing between capsules 
create extremely well-focused, natural stereo 
imaging with no “hole in the middle.” Overall, 
the reproduction of the sound fi eld is precise 
and realistic.

The SASS can accurately convey the ambient 
environment for location recording fi lm-wide 
sound, or synched audio ambience (movement 
of traffi c) where movement heard must precise-
ly match movements in the screen image.

A foam barrier/baffl e between the capsules 
shapes the pickup angle of each capsule in the 
front, and limits overlap of the two sides at 
higher frequencies. Although the mic capsules 
are spaced a few centimeters apart, there is 
little phase cancellation when both channels are 
combined to mono because of the shadowing 
effect of the baffl e.

The SASS can be powered in the fi eld by two 
9V batteries, as well as 12-48V phantom power. 
Separate left and right outputs are low-imped-
ance balanced.
