DESCRIPTION
Introduction
The Sencore SP395 SoundPro Audio Integrator is a quality, high-end audio and acoustic
analyzer designed for audio professionals, commercial audio installers, and audio system
engineers. Its audio analyzing functions make it attractive for virtually anyone involved with
audio acoustics or audio systems testing.
The Audio Integrator employs a powerful DSP
engine. All functions, filters, and processing
are implemented in DSP firmware algorithms.
As each function is selected, loaded into
internal memory and executed, the analyzer
takes on a completely new personality. Over
25 different test functions become possible in
one instrument.
The SP395 is especially good at multi-tasking.
It employs independent input, DSP processing,
output, monitor, and USB circuit sections. For
example, you can run the Sound Study Graph
to record SPL over time, while monitoring the
input in headphones, and simultaneously
feeding the input signals to a PC through the
USB audio interface.
The Integrator uses precision 24-bit A/D and
D/A converters, and internal 64-bit processing.
The input and output amplifier stages are fully
balanced, low noise, high-resolution gain
stages. The result is precision measurements
for accurate audio/acoustic analysis.
SP395 Audio Integrator Features
The SP395 provides multiple audio analyzing features including:
•
Sound Level Meter or (SPL) Sound Pressure Level
: Measures loudness of ambient
sound according to ANSI Type 1 A and C weighting networks and ANSI Class 1 octave
and 1/3 octave band filters. Selectable slow, fast, impulse, or peak sound level
measurement averaging modes.
•
Leq:
Measures linear averaged Sound Pressure Level over a specified period of time to
determine if noise standards are being met.
•
Dosimeter
: Measures noise dosage level according to ANSI S1.25-1991 and ASA 98-1991
specifications for noise studies, machinery noise evaluations, and occupational noise
analysis.
•
Sound Study Graph
: Analyzes and records SPL noise levels over a specified time period
from 1 minute to 24 hours, and graphs the results. Automatically runs multiple sound
studies storing up to 40 sound study tests.
•
Real Time Analyzer (RTA
): An audio spectrum analyzer which graphs the dB level of
each audio octave or 1/3 octave band. Fast DSP audio analyzing can be used for live music
or sound analysis. An ANSI X curve weighting network for motion picture theater setup is
included. RTA graphs can be stored to memory or compared with the “difference” mode
for before and after analysis.
•
FFT Analyzer
: Digital signal processing with three FFTs that graph the dB sound level
with 1/6 or 1/12 octave band resolution to 20 kHz. RTA graphs can be stored to memory or
compared with the “difference” mode for before and after analysis.
•
Energy Time Graph
: Graphs the arrival of sound energy to the microphone input and/or
shows the decay of sound energy in dB over time. Starts with sound initiated from the
