Compressor Parameters
•
COMPRESSOR
[OFF, ON]
Turns the Compressor module on and off.
•
THRESHOLD
[-60dB to 0dB]
Sets the level at which the compressor will begin compressing the signal. For
example, if the THRESHOLD is set to -10 dB, any signal which exceeds -10
dB will be compressed, while any signal lower than -10 dB will be left alone
(uncompressed).
The Compressor Threshold Indicator (shown to the right) indicates when signal is
below threshold, above threshold, or in the OverEasy region. Typically, you will want
to set the threshold parameter so that the lower levels of the signal drop below
threshold and the higher levels exceed threshold. This can easily be achieved by
looking at the Threshold Indicator and adjusting the THRESHOLD parameter until
the indicators alternate back and forth between the

Signal Approaching Threshold
(OverEasy® Turned On)
•
RATIO
[1:1 to INF:1]
This parameter determines how much compression is applied to the signal once it exceeds threshold. For example,
applying a 2:1 ratio would allow the output signal level to increase by only 1 dB for every 2 dB of level increase over
threshold. In other words, 1 dB of compression will be applied for every 2 dB increase in level above threshold. For light
compression, choose a lower ratio. For heavy compression increase the ratio. A ratio setting of about 10:1 or higher
essentially turns the compressor into a limiter. Typically, a setting of 1.5 to 2:1 will yield best results for most applications
where the compressor is used.
•
GAIN
[-20dB to +20dB]
This parameter is used to compensate for the gain lost due to compression. Typically, you can look at the gain reduction
meter and then apply a matching amount of gain. Or you can turn the compressor on and off to A/B the compressed
signal with the uncompressed signal and adjust the gain until the two levels match. By using compression on a signal
and then boosting the signal with the gain parameter, you can slightly increase the average level and create a signal that
sounds a little louder than it actually is. However, care should be taken to prevent over-compression, which can cause
level pumping and increase the likelihood of feedback.
•
OVER EASY
[OFF, 1-10]
One criterion that determines how a compressor will function is called the “knee”. The knee region exists at or around
the compressor’s threshold setting and determines how gradual or abrupt the compression will be. A compressor
with hard knee characteristics won’t compress the signal until it exceeds threshold and will provide a more abrupt
and aggressively compressed sound, as well as retain more of the attack and level of the original sound. Conversely,
a compressor with soft knee characteristics will begin compressing the signal lightly before it has actually exceeded
threshold and then apply full compression once the signal does exceed threshold. This can generate smoother, more
musical compression for applications that require a smooth sound, rather than an aggressively compressed sound.
The OVER EASY parameter in the VENU360’s Compressor module varies the knee characteristics of the compressor.
When set to OFF, the compressor will function as a hard knee compressor, making it sound more aggressive as
described above. Setting this parameter to a setting between 1-10 will cause the compressor to act as a soft knee
compressor, yielding more gradual, smooth, and natural compression. The OVER EASY parameter’s 1-10 range is
referred to as VariKnee™. Lower values provide a slightly softer knee than a hard knee compressor. As you increase the
OVER EASY setting, the knee softens, rounding out the sound. This lets you choose the exact knee that is needed for
the dynamic effect you are looking for.
