Used AUDIO PRECISION SWR-2122M #9264079 for sale

AUDIO PRECISION SWR-2122M is an electronic test equipment designed to measure the performance of audio systems ranging from Room Acoustics to Loudspeaker systems in the lab or in the field. The device incorporates a calibrated, two-channel, wide-range sound pressure level (SPL) meter with measurement capabilities that comply with IEC Class 2 specifications and Class 1 specifications over a wide frequency and dynamic range. With a maximum output level of +20dBu into a 600Ω load, SWR-2122M covers a wide range of audio frequencies, from 100Hz to 80kHz. AUDIO PRECISION SWR-2122M features a Gain-Compensated SPL (GCSL) algorithm which allows simultaneous comparison of multiple SPL channels in various room sizes and configurations. This algorithm optimizes both frequency and time-domain compensation to ensure SPL accuracy and consistency, and to provide accurate SPL measurements even when using various loudspeaker setups. The unit features a USB connection which offers easy setup and data transfer from the device PC. SWR-2122M provides plug-and-play operation while also allowing for full control of the device via a PC GUI and a convenient remote with intuitive push-button control. This is especially handy for conducting tests in loud noise environments or for situations which require a greater number of test settings. AUDIO PRECISION SWR-2122M also offers an automatic shutdown feature that will turn off the unit when the desired SPL levels are achieved, thus ensuring that readings are accurate and precise. A variable expansion measurement function enables investigators to expand the dynamic range of the SPL meter, effectively allowing for greater SPL range accuracy. SWR-2122M is also compatible with various microphone arrangement techniques. The device also features robust temperature performance, with temperature resistance up to +45°C and accuracy up to +/- 0.25°C. The unit also has a 5-minute warm-up period for precise temperature stabilization. AUDIO PRECISION SWR-2122M features a LED display with an intuitive interface, allowing users to conveniently monitor and adjust SPL settings. SWR-2122M offers a variety of accuracy measurement options, including a built-in 3.1kHz filtered C weighting, while also providing the option to export SPL data in one-third-octave, half-octave, filtering, and frequency warping formats. Furthermore, the unit allows for simultaneous A/B comparison of one or two SPL channels via the GCSL algorithm. Overall, AUDIO PRECISION SWR-2122M is an essential piece of test equipment for studying the acoustic behavior of audio systems. It offers state-of-the-art design and features, providing accurate readings in various environments. SWR-2122M is a reliable, highly versatile, and portable instrument for performing precise SPL measurements.
