Bass Meter with functionality of connecting external sensorsFrequency range from 10 to 120 HzCalibrated according to TERM-LAB Classic and MagnumAmplitude range from 100 to 190 dBAllows connecting microphone, power sensor or SPL-sensorUSB and Lab-Bus ports for connecting Next-Lab sensors DescriptionThe multifunctional sound pressure meter USB Bass Meter (Second Edition) is intended for measuring the noise level and sound pressure at low frequency. The device has an extended amplitude range up to 90 dB! The device can be connected to Windows PC or smartphone/tablet PC via USB port. Using the solid-state sensor allows receiving results with accuracy of 0.1 dB. The device is simple in use and does not require additional setting and calibration. A distinctive feature of this device is the Lab-Bus port for connecting external sensors of the NEXT-LAB series. Provided there are external sensors, it allows taking measurements of not only sound pressure, but also the voltage-current characteristics of electric circuits (when using the NEXT-LAB Power Sensor), amplitude-frequency characteristics or noise level of the acoustic system over the entire audible range (when using NEXT-LAB RTA Microphone). Also, if additional NEXT-LAB SPL Sensor is connected, it is possible to measure the sound pressure from two sources simultaneously.ErgonomicsThe device is performed as a monoblock containing the high accuracy solid-state pressure transducer, analogue-to-digital converter and USB interface for connecting with a PC and Lab-Bus port for connecting external sensors. At the back cover, there are vacuum suction cups for affixing the device to any smooth surfaces such as glass. The case of the device is made of shockproof plastic material.FunctionsMeasuring the characteristics of the home, car or concert hall acoustic systemsSetting acoustic systems, e.g. subwoofersMeasuring the noise levelPreparation to autosound competitions on unlimited sound pressure (AMT, EMMA, dB Drag, IASCA, BassRace, etc.)Holding the auto sound contestsMeasuring the sound pressure level (SPL)Spectral analysis of a signal - getting the AFCMeasuring AFC and performing a spectral analysis of the signal using Next-Lab RTA Microphone.Measuring the current-voltage characteristics of direct and alternating current circuits using Next-Lab Power Sensor.Possibility of simultaneous work with two signal sources.Package ContentsUsb Bass Meter (Second Edition) Noise MeterConnecting USB cable for connecting to the PCSpl-Lab Measuring Center software for WindowsAudio tracks for tuning (sine, sweep-tones, noise)
