Compressor
Turning a channel’s COMPRESS control clockwise from its OFF position activates the channel’s
compressor. As the control is moved from the OFF position, the yellow COMP LED will light briefly
to confirm that the compressor is now active. As it is rotated clockwise, the compression threshold
is progressively reduced, resulting in increasingly heavy compression. The yellow COMP LED will
illuminate when compression is being applied to the signal, which will be the case whenever the
signal level exceeds the threshold.
Pressing the MORE button increases the compression ratio, thereby applying more compression to
the signal for the same setting of COMPRESS.
Compressor – additional information
On the Scarlett OctoPre Dynamic, the COMPRESS control is essentially a combined Threshold and
Gain Make-up control: as the threshold is reduced, causing more of the signal to be compressed, the
compressor’s overall gain (often referred to as “Make-up Gain”) is increased, raising the signal level
at the output to match that at the input.
In both modes the attack time is 1.2 ms and the release time is 28 ms.
The two graphs below show the compression characteristics in “Normal” and “More” modes
respectively. The curves include the effect of the make-up gain on the overall signal level.
The four curves represent:
• OFF - Compressor Off
• MIN - COMPRESS control set to minimum
• MID - COMPRESS control set to 12 o’clock
• MAX - COMPRESS control set to MAX
