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 connecting 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 sound pressure 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).
Overload signaling
This output indicates an overload somewhere in the limiter. This can be the measuring microphone
or the audio input. This output has the same function as the overload LED on the front.
Live OK signaling
This output is active as long 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 go into sanction mode and cut off the power
supply automatically. After a pre-set duration the sanction will be dissolved.
Warning signaling
Level OK
Safe sound pressure
These outputs give an impression of the actual sound pressure level with respect to the maximum
allowed level:
•
The warning signaling 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
getting 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 give them an impression
of the sound pressure level.
External VU unit
This is the data connection with the optional SPL-D2 MK
II
display. The external display can also
directly be connected to the SPL6. For this a stereo 6.3mm jack cable is required.
