SI7
The SI7 probe is a two microphone probe featuring adjustable spacing from 12.5 mm to 100 mm. 
The side by side approach eliminates the need for any spacers. Thus the spacing may be adjusted for optimum measurement bandwidth. The 100 mm spacing (twice that of most face to face configurations) permits lower frequencies of operation without special adaptors.
The SI7 is designed to hold ACO Pacific's standard 4012 (1/2 inch microphone preamp). This allows the user to do general acoustic measurements increasing the versatility of the equipment.
SI7BNC
The SI7BNC is designed to hold ACO Pacific's ACOTron™ 4212 preamps. Has BNC cabling - permitting IEPE power.
Sound Intensity (Acoustical Intensity) permits accurate source location and measurement of sound sources in highly reverberant environments. Applications include measurement of: fan noise, speaker cabinet sound radiation, heavy equipment noise; and profiling a horn drivers. The side by side configuration allows measurements to within a few millimeters of a working surface like speaker cones or tires.
