SP495 SoundPro Audio Consultant
The SP495 SoundPro Audio Consultant is a handheld audio analyzer. It can be used in convention centers, concert pavilions, theme parks and public sound control systems.
Overview
The Audio Consultant is a powerful acoustic analyzer for design/consultation. It provides acoustic/audio analysis for analyzing distributed sound, sound reinforcement systems, live sound applications and industrial sound analysis; all in one handheld, battery-operated instrument.
The SP495 features Noise Curves, Multi-Band Decay analysis, Time Delay Analysis (TDA), TerraLink software for 3D graph analysis, Speech Intelligibility, electrical audio tests (Tech Bench) and digital output to S/PDIF, Toslink, and USB ports. An Impulse Recorder, or Stereo Recorder, records audio inputs to memory (wav) files. Files can be stored to an SD memory card.
The SP495 features a color LCD display, dual phantom-powered high-gain/low-distortion microphone inputs, powerful dual-FFT processing, integrated USB audio interface, and independent analog monitoring. Supplied accessories are a Type 2 standard measurement microphone, XLR cable, USB cable, impedance test cable, power adapter/charger, battery and carrying case.
Features
Here's What the SoundPro Audio Consultant Delivers:
Fast and accurate adjustments of speaker coverage and cluster alignment, time delays and speaker frequency response equalization to ensure a high-performance, problem free installation. Portable, handheld (5 hours battery run time) in a ruggedized case means you can conveniently make precise audio system measurements wherever you do commercial audio work. High resolution color LCD, 1/30 octave FFT Analyzer, high-res ETG, bi-directional stereo audio USB interface, digital audio LPCM outputs (S/PDIF, Toslink & USB), and high level analog audio outputs. Impulse Recorder records room impulse response for transfer to acoustic analysis programs. SD memory card for transferring Recorder wav files, plus graphical and textual memory test data. Macro function records and plays back a timed series of user-input control actions. Auto HT and Auto Polarity Test compatibility with DAG5161 Multichannel Digital Audio Generator. Optional firmware add-ons - TechBench (electrical signal/component tests), Speech Intelligibility (ALCONS, RaSTI, STI-PA), Time Delay Analysis (TDA), NoiseCurves (NC, RC, PNC) with overlaid RTA noise curves, Transmission Loss (STC, NIC), Multi-Band Decay, and Audio Stethoscope; you'll never be caught short.
