The SPL5 can be used in live-situations to monitor the audio level produced by a live-band, and sanction is necessary by cutting off the mains voltage or give an optical indication to the band. In a non-live situation, so music played over the PA-equipment the SPL5 is inserted after the mixer, and before the amplifiers. It uses the microphone to determine the audio level, and attenuates the output level is required.
New in the SPL5 is the possibility to store the sound-level data, and event history over a period of two months. Besides a limiter the SPL5 acts as a decibell logger. With the PC-software the limiters memory can be read out. Configuring the limiter is done with the same software. But before it becomes possible to make any changes this software has to be registered; this makes it impossible for un-authorised people to alter the limiters configuration.
This PC-software makes it possible to control the limiter over a computer-network, and even over the Internet!
