COMPRESSOR/LIMITER

,  or  dynamics  processor  of  the  output  channel  with 

signal-peak detection. It has the following controls: 

 

THRESHOLD

: activation threshold of the processor (volts) 

 

RATIO: gain reduction of the processed (compressed) signal compared to the 
incoming signal 

 

ATTACK

:  time  it  takes  the  compressor  to  start  compressing  after  the 

threshold has been reached 

 

RELEASE

:  time  the  compressor  uses  to  stop  compressing  after  the  input 

signal has fallen below the threshold 

 

MAKE-UP

: gain applied to the signal after compression, to globally increase 

its level once dynamically modified 

 

KNEE

: type of curve (transition zone around the threshold) that determines 

whether the bend in the response curve around threshold is abrupt (HARD) 
or gradual (SOFT) 

 

GR (GAIN REDUCTION):

 compression real time indicator (dB), very useful to 

adjust different parameters of the compressor, including MAKE-UP GAIN 

5

 

COMPRESSOR/LIMITER

,  or  dynamics  processor  of  the  output  channel  with 

signal  RMS-level  (Root  Mean  Square)  detection.  It  has  the  same  controls  and 
indicators as the peak compressor. 

6

 

COPY/PASTE

: icons to copy the settings from one channel and "paste" them in 

another, cloning the settings (all settings, except the label or channel name). 

7

 

LOUDSPEAKER PRESET

: allows you to save a "partial" preset or configuration 

of an output channel, on your computer or on a storage  device, which will be 
sometimes  directly  associated  with  the  characteristics  of  a  specific  speaker 
system model (crossover frequencies, delay for time alignment, EQ, compression 
and limiting, etc.). 

 

 

 

 

 

This preset can be loaded subsequently in ALMA24/ALMAcard devices requiring 
an exact copy of the settings it contains.
