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 design1, 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 field is precise and realistic.

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

A foam barrier/baffle 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 baffle.

The SASS can be powered in the field by two

9V batteries, as well as 12-48V phantom power. Separate left and right outputs are low-imped- ance balanced.

Polar pattern (each channel): Omnidirectional at low frequencies, unidirectional at high frequencies. See Fig. 2.

Impedance: 150 ohms rated (240 ohms actual), bal- anced. Recommended minimum load impedance 1000 ohms.

Open-circuit sensitivity: 6.0 mV/Pa* (–44.5 dB re

1 volt/Pa*).

Power sensitivity: –44 dB re 1 mW/Pa*. –136 dB EIA.

Equivalent noise level: 20.5 dB SPL typical (0 dB=.0002 dyne/cm2), A-weighted.

S/N ratio: 73.5 dB at 94 dB SPL.

Maximum SPL: 150 dB SPL at the diaphragm pro- duces 3% THD.

Polarity: Positive pressure on the diaphragm pro- duces a positive voltage on pin 2 with respect to pin 3 of the output connector.
