C671
The C671 module is a variation of a Fairchild 670, with slightly faster signal tracking to
accommodate modern production styles, and yet still imparts a ‘warmth’ into the audio
output. The McDSP C671 is sonically identical to the original C670 module from the 6030
Ultimate Compressor plug-in, but includes its own makeup gain, as do all the other 6060
compression modules. For this reason, all the compression module name enumerations are
increased by ‘1’ to note the addition of the makeup gain in each module.
MT2
The Moo Tube module emulates an all tube design with a few unique twists. Mid range
sensitivity has been modified by McDSP engineering, attack and recovery times are gentle yet
usable for many applications, and the output frequency response is variable based on the amount
of compression.
iC2
The iComp module is an all original McDSP design. Attack and release times are not available
on this module, and are instead automatically updated based on user selected threshold and
ratio control values.
Opto-C3
The Opto-C3 and Opto-L3 modules use an electro-optical attenuation circuit model for
compression (Opto-C) or limiter (Opto-L) applications. The use of an electro-optical circuit
causes the dynamic compression to ‘back off’ after a certain amount of dB reduction is
achieved. This feature is sometimes referred to as a ‘dog tail compression effect’. Both the
Opto-C3 and Opto-L3 modules feature a feedback compression (or limiter) mode in which the
compressor (or limiter) output is the key signal. As more gain is applied, the compression
amounts also increase, creating a convenient way to audition more compression at roughly similar
audio levels.
Opto-L3
The Opto-C3 and Opto-L3 modules use an electro-optical attenuation circuit model for
compression (Opto-C) or limiter (Opto-L) applications. The use of an electro-optical circuit
causes the dynamic compression to ‘back off’ after a certain amount of dB reduction is
achieved. This feature is sometimes referred to as a ‘dog tail compression effect’. Both the
Opto-C3 and Opto-L3 modules feature a feedback compression (or limiter) mode in which the
compressor (or limiter) output is the key signal. The addition of the feedback mode in several
of the compression modules is one of the many new features of the 6060 Ultimate Module
Collection plug-in.
BC-23
Based on a more ‘traditional’ English design, the British C-23 (BC-23 for short) module
offers control for threshold, ratio, attack, and recovery. Internal circuit smarts help
prevent unwanted distortion, even at extreme compression settings (low threshold, fast
attack and release). As found in several of the compression modules in the 6060, there is
also a feedback compression mode.
Over EZ3
The Over EZ3 module incorporates a smooth knee response with a flexible control
configuration including user selectable threshold, ratio, attack, and release. New additions
in this module include the feedback compression mode, and the rare and ‘careful how you use
it’ negative compression mode.
SST'78
The SST’78 module is a solid-state circuit model with a McDSP designed key circuit. For the
curious, SST does not stand for Super Sonic Transport. The SST’78 features feedforward and
feedback compression modes, as well as a negative compression mode. Because the SST’78 is
capable of very fast attack and release times, caution is advised when engaging its negative
compression circuit.
FRG446
The FRG446 module, commonly referred to as ‘The Frog’ by McDSP engineering staff, uses a
moderately aggressive compression design to quickly respond to audio input. As with other
6060 compression modules, feedback (and feedforward) compression modes are offered, as is
the dangerous negative compression mode.
D359
The D359 module is the most aggressive compressor in the 6060 Ultimate Module Collection
plug-in. An LED style GR meter is also used to show as much dynamic range control response
as possible. Feedback (and feedforward) compression modes are offered, as is the (did we
mention dangerous?) negative compression mode.
