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.

Connections
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
cover and the cover is removed, the limiter will store this action into it's memory and optionally lock
the audio path. This sanction can only be reset usin the reset key.

Microphone input
Connect the supplied measurin microphone here. The wirin of the microphone can be
len thened with standard microphone cable. Pay attention to the polarity of the wirin . If
the microphone is wron ly connected it won't work. The limiter will ive an error messa e,
and the volume will be extremely reduced.
The microphone should be installed so that it 'hears' both sound from the speakers as well
as the sound from the crowd in the room. The microphone can be placed closer to the
speakers when the maximum allowed level is very low. This reduces the effects of
back round noises.

12 Installation DATEQ SPL-5 MK2 manual UK
Audio inputs
Balanced audio inputs. Pin 1 and 3 of the XLR connector should be linked to ether when
the mixer only has unbalanced outputs. The mixers' si nal can be connected to pin 2, and
the round to pin 1.
Audio outputs
Connect the power amplifiers here. Connect pin 2 (si nal) and pin 1 ( round) when the
power amplifier does not have balanced inputs.
External attenuator
This input can be used to reduce the maximum sound pressure level with an external
potentiometer. The maximum sound pressure level can be reduced by connectin a linear
10kOhm potentiometer between pin1 and pin 14.
This can be useful to reduce the sound pressure level from behind the bar. It is also
possible to automatically reduce the sound pressure level, for instance when in the summer
some doors are opened.

Signaling
Reduction signaling
An indicator to show that the limiter has reduced the si nal level can be connected to this output.
This output has the same function as the reduction LED on the front of the limiter (Audio
reduction).
O erload signaling
This output indicates an overload somewhere in the limiter. This can be the measurin microphone
or the audio input. This output has the same function as the overload LED on the front.
Li e OK signaling
This output is active as lon as the limiter is not in sanction mode. A solid-state relay, to turn off
the power supply of the live band, can be connected to this output. If the maximum sound
pressure level is exceeded by a band, the limiter will o into sanction mode and cut off the power
supply automatically. After a pre-set duration the sanction will be dissolved.
Warning signaling
Le el OK
Safe sound pressure
These outputs ive an impression of the actual sound pressure level with respect to the maximum
allowed level:
•The warnin si nalin output becomes active, as soon as the maximum sound pressure level is
exceeded.
•Level OK indicates that the sound pressure level is below the maximum allowed level, but is
ettin close (0...12dB span).
•Safe sound pressure indicates that the sound pressure level is well below the maximum allowed
limit (12dB or more).
These indicators can be placed near the disc-jockey, or the live band, to ive them an impression
of the sound pressure level.
External VU unit
This is the data connection with the optional SPL-D2 MK , SPL-D3 or SPL-EXT3 display. The
external display can also directly be connected to the SPL-5. For this a stereo 6.3mm jack cable is
required.

Operation
1 2 3 4 5 6 7 8 9
1. Power switch:
switches main AC power on or off for the limiter.
2. Display:
The display shows all important values like system time, current sound level in different values
(dBA, dBC, Leq and line level) and the current reduction.
3. Timeslots:
these LED's indicate the current active timeslot. Each timeslot can be confi ured with it's own
time and maximum sound pressure level.
4. Status LED's:
•AUDIO PRESENT indicates active audio detected on the audio inputs of the limiter (detects
at -24dB),
•REDUCE LED indicates the limiter is actively reducin the audio si nal,
•OVERLOAD LED indicates an overloaded si nal present at the line or microphone input
(12dB above threshold level),
•SANCTION LED indicates the limiter in sanction state. On fraud detection the limiter will also
o into sanction state. The sanction LED will blink. Reset by timer or reset key.
1. Reduction LED's:
The reducion is indicated in the percenta e of the maximum allowed limiter reduction. Default
this is set to 30dB that results in 6dB/LED.
•All off: no reduction
•1 LED on: 1-20% reduction
•2 LED's on: 20-40% reduction
•3 LED's on: 40-60% reduction
•4 LED's on: 60-80% reduction
5 LED's on: 80-100% reduction
2. Bypass switch:
This switch puts the limiter fully in bypass. The limiter will no lon er act as limiter, but will only
record measured sound levels.
3. USB:
USB connection for readin historic sound levels and chan in the limiter settin s.
4. Bypass LED:
Indicates the limiter is in bypass mode. The bypass switch or bypass callander is active.
5. Key switch:
After removin the cover lid, the key needs to be set to the blue position to reactivate the
limiter. After reactivatin the key needs to be returned to the red position. The key switch also
resets sanction.
