SHARK DSP110
2.3 The integrated  DelayIn addition  to speakers on  or near  the stage,  major-scale installations  often have
speaker groups positioned at a distance to the  stage or flown above the audience, in
order to  provide listeners away  from the  stage with  direct sound.  However, since
sound needs some time to travel around (343.6 m/sec at 20°C, accelerates by 0.6 m/
sec per °C), it reaches the audience not simultaneously but gets delayed by a  certain
amount. To make up for the different  run times between stage and remote speakers,
the latter  must be provided  with an  electronically delayed  signal, which  is usually
done by means  of special-purpose  Delay devices.  You wont  need them,  however,
when youve got a SHARK, as the  DSP110 integrates a Delay Line circuit giving  you
the same  convenience of operation  as dedicated  devices. Simply  measure the
distance between the various speaker groups and enter this value (in meters or feet).
Chapter 2.1.3 shows you how to  wire the DSP110 in this type  of application.

2.4 The Noise Gate  functionThe main  task of a  Noise Gate  is to  separate unwanted  background noise  from
wanted signals and  remove noise  inaudibly. A  so-called downward  Expander
automatically reduces  the overall  level of  all signals  below an  adjustable threshold
and thus expands the  dynamic range of  the program material.
In live or stage applications and  multi-microphone systems, in particular, the SHARK
has a variety of possible  uses: as a moderately  and accurately set Gate  it efficiently
suppresses background  noise, compressor-induced noise  build-up and  crosstalk
