DESCRIPTION
• SPL20 allows audio pressure level metering and recording. The associated probe is CAP20.
The probe can be located about ten meters. Metering and recording are under A or C frequency
weighting at user's choice. Thus metering and recording are at overall level
• SPL80 now in development, will allow soon, measurement and recording in octave bands .
• Metering is simultaneously achieved in fast and time weighting (Leq) 1mn, 5mn, 10mn and
60mn. Recording is at user's choice in time weighting 1mn, 5mn, 10mn and 60mn. Historical
covers the three previous months.
• Reading and settings use LAN port (IP net). Several SPL20 installation is possible, thus
allowing audio level analysis in various places, like for large rooms, or stadium. Each SPL20
will have its own IP adress.
A very important feature, is the embedded WEB server. This allows historical reading and
downloading using IP under any OS and web browser, avoiding use of specific software.
• Real time reading allows instantaneous level display (1s integration), Leq level (1mn, 5mn,
10mn, 60mn) and a Leq variation graph. Historical exportation is in text or CSV format.
• USB port supplies power, and is used for internal software update. A 5V power supply with USB
connector is supplied.
• Two static relays output (Opt-Mos) allows external equipment switching. Opto-Mos works as a
dry loop without mechanical relay problems. These output allow to switch a light (requires an
interface) or audio level control.
One of these outputs allow supplying AFF05, a level indication unit, featuring 5 different colors
lights (-3, -1, 0, +1, +3 dB). 0 dB relative level can be adjusted in level and Leq. AFF05 allows
sometimes a better approach of acoustic levels absolute values to users.
• SPL20 features a phantom power supply feeding the CAP20. This allows handling balanced
signals, to avoid external disturbances. Connectors are XLR. Phantom power supply
motoring, detects short circuits or disconnected pins. Should a problem occur, it is displayed on
SPL20 and web server. Light indicators allow checking A or C weighting, and GPO1 and GPO2
state.
