Output Processing - Ecler ALMAcard Bedienungsanleitung

5.5. Output processing

The processing available for each audio output channel is the following:
1) Volume, Mute, polarity inversion and delay (up to 1 second, displayed in units of time or
distance) controls. Also included are 2 level meters ("pre-processing" and "post-processing")
for the output channel.
With SELECT, choose the signal source for each output channel, between NONE, IN1, IN2,
IN1+IN2 (mono mix from a stereo source) or GEN (internal signal generator).
AMP GAIN allows you to set the gain of the amplifier that will work with the
ALMA24/ALMAcard device. This parameter is critical for the compressor/limiter to process
correctly the signal, in order not to exceed a certain level and/or to protect the installation
speaker systems.
2) CROSSOVER, or low-pass and high-pass filters to define a frequency range to work on
amongst the entire audible spectrum. Available filter types are:
•
BYPASS (filter not activated)
•
BESSEL 12, 18, 24 or 48 dB/oct
•
BUTTERWORTH 6, 12, 18, 24 or 48 dB/oct
•
LINKWITZ-RILEY 12, 24 or 48 dB/octave
3) PARAMETRIC EQ, or parametric equalization filters to enhance or attenuate different
frequency ranges of the signal. 8 filters of this type are available for each output, and each
one of them can have the following setting:
•
BYPASS (filter not activated)
•
Parametric EQ (controls for frequency, Q or filter width and gain or attenuation of the
affected band)
•
HIGH SHELF, 6 or 12 dB/octave
•
LOW SHELF, 6 or 12 dB/octave
•
HIGH PASS, 6 or 12 dB/octave
•
LOW PASS, 6 or 12 dB/octave
•
ALL PASS, 1st or 2nd order
