The S30 is an omnidirectional (pressure) microphone designed and calibrated for measurement purposes. It is a pre-polarized condenser microphone directly coupled to a wideband, low output impedance preamplifier. The S30 requires a standard 48 V phantom power supply.
It features a linear free-field frequency response from 9 Hz to 23 kHz, very low handling noise, uniform polar pattern, and high SPL handling capabilities. Its unique circuitry excludes the transconductance of the input FET from the overall gain structure. This means the sensitivity remains very stable when the microphone is subjected to variations in ambient temperature.
The S30 is ideally suited for acoustical measurements including loudspeaker design and quality control, sound system setup and troubleshooting, room acoustics, or any application where an accurate free-field measurement microphone is required. The wide linear minimum-phase response and fast well-damped impulse response make the S30 an excellent microphone for loudspeaker design, especially for time domain measurements.
Each microphone is delivered with its own calibration chart providing its individually measured open-circuit sensitivity and the frequency response curve. A mounting clip and a calibrator adapter are included with the microphone. The S30 is simple to operate. Connect the microphone to a microphone preamplifier supplying 48 V phantom power using a standard XLR microphone cable. Please allow up to one minute for the microphone to settle. Plugging in the microphone “hot” (phantom power already present at the input) will not damage the microphone, and is actually preferred for faster settling. For optimum results it is recommended to point the S30 toward the sound source.
