After setting, the automatic gain will take this setting value as the maximum amplitude to adjust automatically. (clockwise to increase) Â Connection: Audio terminal input adopts 3.5mm male headphones, connect it to computer headphone output interface via the audio branch, the other end of the branch connects external audio equipment. Please check whether the audio cable or branch has good contact if the audio has noise or the spectrum has background noise under mute and MIC off mode when using. Package Includes: 1x AS256 Music Spectrum
This sound calibrator generates a stable acoustic signal at a controlled frequency and amplitude to verify the accuracy of your sound level meter. The R8090 is compatible with all 1/2" diameter microphones.
The Amprobe SM-20 type 2 sound meter measures and records sound pressure levels (spl) in environmental quality control and acoustic analysis applications, such as when checking compliance with noise pollution regulations and health and safety codes. The meter can record measurements for future reference, and it comes with a data cable for connecting the meter to a computer to transfer recorded data for viewing and analysis on a computer using the included software. It has two measurement settings. The â€œAâ€ weighting is for taking measurements where there is low to moderate ambient noise, such as in an office. The â€œCâ€ weighting is for taking measurements where there is loud low-frequency background noise, such as in machine shops. The meter offers a choice of two response speeds. The fast 125-millisecond response setting measures the average sound level in environments with steady ambient sound, and the slow 1-second response setting measures peak noise levels in environments with fluctuating ambient sound. The 1/2-inch condenser microphone comes with a windscreen to shield the microphone in outdoor conditions with wind speeds over 10 m/sec (22.3 mph). The maximum or minimum reading mode displays the highest or lowest reading in a session to track sudden increases or decreases in measurements. The data hold function keeps a reading on the display even after the meter is disconnected or the measurement changes. The meter's backlit liquid crystal display (LCD) is readable in low light and shows measurements in 0.1 dB increments up to 4 digits. The auto-power off function turns off the unit after 5 minutes of non-use to conserve battery life. The included software can be installed on computers that run the Windows 95, 98, NT, ME, 2000, XP, or 7 operating system.Specifications Frequency range 31.5 hertz (Hz) to 8 kilohertz (KHz) Sound level measurement range, â€œAâ€ weighting 30 to 130 decibels (dB) Sound level measurement range, â€œCâ€ weighting 35 to 130 dB Dynamic ran...
