The SPL-D3MK2 has the added bonus of working with a processor instead of an SD card.This has the great advantage that now basically every minute is stored directly and can be read out.Furthermore it is equipped with a network function, through the DHCP setting multiple SPL-D3 in a network can be monitored.And finally the unit can now also be powered from the network using PoE. Please take into account the capacity of the PoE. power supply.


The SPL-D3 MKII is an advanced audio level display that stores the sound level samples for at least twelve months. The sound level samples can be viewed using the configuration software or externally stored through on a USB FAT32 drive. Other important data is also stored like powering up, sanctions or possible tampering.

Using the configuration software the SPL-D3 can be read out and adjusted.
On release Windows 7 platforms and later are supported. All users can only view settings and logging. To adjust configuration settings an additional password and license file is required. To connect to the SPL-D3 a windows computer with USB support is required.

The SPL-D3 uses a measurement microphone to determine the actual sound level. When measurement shows the sound levels are about to exceed, the display will change from green to orange and red when levels are actually exceeded.

The special calender functions allow for different sound levels during the day and year.

With the special SRL-1 circuit breaker an external warning light can be connected along the the main power supply for example the DJ booth monitor. This way the maximum sound level is always insured without touching the sound quality.

Theatre mode disables the display while sound level is normal. Only on (possible) exceeding the maximum set sound level, the display will turn on again.
