SP395A SoundPro Audio Integrator
Overview
The Sencore SP395A SoundPro Audio Integrator provides comprehensive, easy to use audio/acoustic analysis, for analyzing distributed sound and sound reinforcement systems, plus live sound applications and industrial sound analysis; all in one handheld, battery-operated instrument.
The Audio Integrator makes easy work out of any acoustic or audio system analyzing challenge. It simplifies speaker coverage analysis, speaker cluster time alignment, speaker time delay adjustments, and frequency response equalization. It tests and documents background noise level, reverberation time band-by-band, and system speech intelligibility.
The Audio Integrator analysis functions are implemented with 64-bit DSP firmware algorithms. As each function is executed, the analyzer takes on one of over 25 different audio analysis personalities. A standard core of these test functions is standard equipment. Optional test functions are grouped into "firmware modules" for purchase at any time, at which time they are unlocked for use. This permits the SP395A to be upgraded (in the field) for special applications, as needed, to better fit budget requirements.
The SP395A features dual phantom-powered high-gain/low-distortion microphone inputs, powerful dual-FFT processing, integrated USB audio interface, and independent analog monitoring. The SP395A is supplied with a Type 2 standard measurement microphone, XLR cable, USB cable, impedance test cable, power adapter/charger, battery, and padded carry case. The removable lithium-ion rechargeable battery provides 4-5 hours of portable testing.
Features
Here's What the SoundPro Audio Integrator Delivers:
Fast and accurate adjustments of speaker coverage and cluster alignment, time delays and speaker frequency response equalization; ensures a high-performance, problem free installation. Tests and documents band-specific background noise, room reverberation, and speech intelligibility to identify problem areas and sign-off the system installation. Easy to use and interpret user-interface helps you quickly make the test and get the readings you need. Portable, battery operated (5 hours run time) and handheld instrument in a ruggedized case means you can make precise audio system measurements wherever you do audio system installations. Optional software feature add-ons such as speech intelligibility, time delay analysis and more mean you are never caught short.Specifications
