ACO Pacific, Inc. products

The 7052PH Type 1.5 phantom powered measurement microphone system offers a cost effective solution to acoustic measurements from phantom powered sources. Designed to work with from 48 to 18 Vdc Phantom Power, the 7052PH features the 7052H. Its rugged Titanium diaphragm provides excellent longterm stability and temperature performance. The companion 4048 ACOtronTM preamp offers both low noise and a wide dynamic range. A WS1 3` Windscreen is included.

The 7052SYS Type 1.5 measurement microphone system offers a cost effective option to acoustic measurements. Perfomance: 4 Hz to >20 kHz response, 20 mV/Pa sensitivity and a `A` weighted noise floor less than 20 dBA. Compatible with ACOtronTM,CCLD, IEPE, CCLD, IEPE equipment the 7052SYS features the 7052H Type 1.5 with its rugged Titanium diaphragm for excellent longterm stability and temperature perfomance, the 4212 ACOtronTM preamp offering both low noise and a wide dynamic range, and the WS1 3`.

The MK224PH IEC61094-4 compliant phantom powered measurement microphone system offers a cost effective solution to acoustic measurements from phantom powered sources.

The MK224SYS IEC61094-4 compliant measurement microphone system offers a cost effective option to acoustic measurements. Perfomance: 8 Hz to 18 kHz response, 50 mV/Pa sensitivity and a "A" weighted noise floor less than 14 dBA. Compatible with ACOtron™,CCLD, CCLD, and IEPE equipment the MK224SYS features the MK224 IEC61094-4 compliant with its rugged Quartz Coated Nickel diaphragm for excellent longterm stability and temperature perfomance, the 4212 ACOtron™ preamp offering both low noise and a wide dynamic range, and the WS1 3".

The SI7 probe is a two microphone probe featuring adjustable spacing from 12.5 mm to 100 mm. S17 probeThe 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.

The ACOtron 4212 is designed to work with both prepolarized (electret) measurement microphones, accelerometers and other charge devices. The 4212 may be powered from industry standard IEPE or CCLD (Constant Current Line Drive) sources like the IEPE equivalents found in many measurement instruments. The 4212 permits maximum utilization of available current and supply voltage.

The Model 3025, "Extremely Random" Precision Noise Generator supplies White and Pink Noise, and a 1 kHz reference signal. Crystal controlled - the pseudo random circuitry provides a 6.5 Day pseudo-random cycle time, assuring a "Extremely Random" noise source.
