ntroduction
The SPL-5 MK2 is a sound level limiter that records the sound pressure levels for at least 180
day's. Other events like power cycle, tamper detections or overload on sound level are also
recorded.
Usin the SPL-5 MK2 confi uration software the unit can be confi ured and sound sample data
can be read. On release of the SPL-5 MK2 the confi uration software is supported by windows 7
and hi her. In normal use the SPL-5 MK2 connected to the software is read only. Users can read
all settin s and decibel lo in . To chan e any settin the installer license in combination with the
installer password is required.
To connect to the SPL-5 MK2 a windows-computer with USB support is needed. When the SPL-5
MK2 is connected to a local area network or an internet connection, the software allows to connect
remotely.
The limiter uses an external measurement microphone to determine the current sound level. When
the sound level exceeds the maximum allowed level the limiter will reduce the output level to
ensure the sound level stays within it's limits.
Usin the time and bypass calendar the SPL-5 MK2 can adjust the maximum allowed sound level
automatically durin the day, week and year.
When connected, the special SRL-1 sta e relay an external warnin li ht can be connected and if
needed the power of for example a DJ booth monitor can be cut. This way the sound level is
secured without any compromises to the quality of sound.

nstallation
The limiter is installed in between the audio source (a mixin desk for example) and the speaker
amplifier.
When calibratin the system, the power amplifier has to be set to maximum output level. The
limiter will reduce the si nal as much as needed. When used at nominal level the established
sound pressure limit will not be exceeded after confi urin the limiter. However if in any case this
should happen, e. . When the mixer is used above the nominal level, the limiter will automatically
adjust the si nal to ensure the sound pressure level remains below the maximum allowed level.

To prevent modification of the connections after calibration and sealin , the connectors of the
limiter are inaccessible after sealin of the cover plates at the front. To access the connector
board, remove the ri ht cover plate at the front panel.
Unfasten screw (A) with a torx-screwdriver (see illustration). Now remove the 4 torx-screws (B)
from the top lid. The top cover can be removed now. Gently lift the front side a little, and slowly
shift the top lid to the rear. The connector board will become visible.
The SPL-5 MK2 is equipped with balanced in- and outputs ensurin premium sound quality over
lon er distance. After installin the limiter the cover plate can be replaced, locked and sealed,
ensurin no chan es to the installation can be made. If for some reason the seal is broken, the
