The Six “Tweakers”
“AGC Depth”
Some users prefer deeper AGC action than our Factory presets
provide while others prefer less. The “AGC Depth” tweaker
allows this parameter to be adjusted up or down from our
Factory settings.
Higher settings will tend to hold fading program levels up for
longer periods of time. Likewise, lower settings leave less gain
available to pull up the softer passages in programming.
Note: the VP8 GUI indicates up to 30dB of AGC/Compressor gain
reduction while the front panel is limited to 22dB. Because there is
over 48dB of distortionless gain reduction available in the algorithms
users need not be overly concerned about deep amounts of AGC
activity shown on the Ceters.
Tech Tip: Our feed forward algorithms sound exactly the same
at 10dB of gain reduction as they do at 30dB. Therefore driving
the AGC harder won’t make the resulting sound ‘denser’. That task is
best left to the Compression and Density controls…
“Compression”
While the “AGC Depth” tweaker adjusts how deep the
compression is, the “Compression” tweaker adjusts how audible
it is. Pushing the tweaker up to higher numbers causes an
increase in the audibility of compression. This effect may be
desirable in some formats in order to create a certain level of
‘excitement’ on the air. Likewise reducing the setting of the
“Compression” tweaker reduces the audibility of compression.
Those seeking that old ‘60’s’ retro sound will find the Compression
tweaker quite useful.
Tech Tip: The Compression tweaker primarily alters the
difference between slower AGC and faster Compressor activity.
For very dynamic material higher settings of the Compression tweaker
can become quite obvious. The reverse is also true – very compressed
source material will be affected less by the Compression tweaker.
