Connectors
MIC IN
Jack connector for the measuring microphone, supplied with the SPL3 and
SPL3
TS
. The limiter does not function without a connected microphone,
except when the microphone is bypassed. The microphone cable can be
extended, maximum is 100 meters (300 feet), but be aware of the polarity of
the symmetrical cable. Mount the microphone to the wall or ceiling. Try to
choose the position of the microphone in such a way, that the microphone
picks up a good quality audio-signal. Try to prevent resonance for certain
frequencies, or feeding the microphone with a filtered sound. Experience
learns that it is advisable to try to position the microphone not too close to the
crowd, so the balance between "human noise" and "electronic noise" tends
to tip the scale in favour of "electronic noise". Sometimes authorities dictate
the location where the measuring microphone should be mounted.
AUDIO IN L/R
Balanced audio inputs left and right.
AUDIO OUT L/R
Balanced audio outputs left and right.
EXTERNAL
ATTENUATION
INPUT
External volume control is possible by connecting a 10k
Ω
variable resistor.
This way it is possible to control the volume from another place than where all
the equipment is situated, for instance behind the bar.
REDUCTION
Connection for LED's or solid-state-relays, for external signalling of the
REDUCTION situation (20 V DC / 10 mA).
