GAIN
: Gain control. Adjust every way’s gain to adapt the signal level received
from the mixing desk and adjust the level delivered to each amplifier and level
the sensibility of each way.
DELAY
: Configurable delay. In each output we dispose of 4.85mseg. With the
delay it is possible to correct the sound boxes´ positioning in a multi way
system and avoid cancellation problems caused by phase problems.
PEQ
: Equalization. There are 7 totally configurable filters per way. These filters
can be Parametric, Shelving of Low and High of 6dB/oct, LowPass, HighPass
(with and without Q), BandPass, StopBand and AllPass of first and second
order. PEQs mission is to correct and optimize each transducer and its
enclosure’s respond, obtaining a flat frequency or other, as required.
CROSSOVER
: Bands separating filters. There are Linkwitz-Riley, Butterworth
and Bessel filters up to 24dB/oct. You can also put them into Bypass,
inactivating them, so this way disposing of the corresponding way in full band.
DYNAMICS
: Dynamics section. The
LMS 221 / LMS 266
has a sophisticated
algorithm of dynamics which uses a RMS detector with attacks and liberation
controllable through the respond speed constants of the dynamics. Includes
dynamic curves C. R. I. (Continuous Ratio Increment). These dynamic curves
work like a compressor-limiter with ratio depending of the signal level,
progressively passing from a relation 1:1 to 1:
∞
. This way the dynamics control
beginning is gradual and totally transparent and guarantees much more
headroom than a traditional limiter. There is also a noise gate available, which
will respond with the time constants of the general dynamics.
