Microphone input
Connect the supplied measuring microphone here. The wiring of the microphone can be
lengthened with standard microphone cable. Pay attention to the polarity of the wiring. If
the microphone is wrongly connected it won't work. The limiter will give an error message,
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
background noises.
Link
This is the data connection with the optional SPL-5MK2, SPL6 or SRL1 stage relay. For this a
stereo 6.3mm jack cable is required.
