EQ4000
 
Based on the E-Series channel EQ processing from one of the best-known British recording consoles, the EQ4000 comprises high frequency, high-mid, low-mid and low frequency sections.
The low and high frequency sections are independently switchable between 'bell' and 'shelf' modes while the mid sections provide fully parametric equalization with variable gain, frequency and Q.
 
The plug-in emulates both the earlier 'Brown' (82E02) and later 'Black' (82E242) versions of the original hardware while HF - HMF and LF - LMF cross-linking emulates the control interaction of the original design.
 
Developed by a design team including two former Solid State Logic (SSL) engineers, with detailed understanding of the original hardware.

PTC-2A Vintage Pultec EQ Plug-In
 
"A fantastic sounding plug-in" - pro-tools-expert.com
 
The classic signature sounds of one of the world's most sought-after vintage EQs, emulated for Windows, Mac and Linux.
 
Even with modern digital equalizers, low-end boost can come at the expense of focus and definition.
 
In contrast, the elegant simplicity of the vintage Pultec EQP-1A design, renowned for its signature 'low-end trick' - the ability to boost and cut low frequencies at the same time - adds powerful, tight bass boost without sacrificing detail.
 
The PTC-2A is an affordable high quality emulation of this most sought-after vintage EQ. Separate boost and attenuate controls allow simultaneous low frequency boost and cut, replicating the signature Pultec sounds while a transformer-coupled valve amplifier emulation further enhances the vintage qualities.

The classic vintage Pultec mid-range EQ
 
Emulating the classic vintage Pultec MEQ-5 mid-range EQ, the PTM-5A replicates the sought-after passive filter character of the original, providing a versatile equalizer capable of subtle sonic enhancement or adding more obvious bite to the mid-range to help elements of the mix stand out.
 
Ideal for acoustic instruments, drums and vocals, the PTM-5A perfectly complements the more familiar PTC-2A vintage Pultec EQ, much the same as the hardware MEQ-5 and EQP-1A units.

FC70 Vintage Fairchild 670 Limiter Plug-in
 
The effortless control and uniquely musical character of one of the best-known vintage compressor / limiters.
 
Taming the dynamics of a mix is often necessary, but can leave it sounding lifeless and unexciting.
 
Conversely, the FC70 keeps the mix in check without robbing it of power and detail, emulating the legendary smooth, effortless dynamic control and uniquely musical character of the classic Fairchild 670 limiter.
 
Using measured data and schematics from genuine hardware, the FC70 replicates a fully balanced transformer-coupled signal path combined with an innovative delay-free feedback algorithm which mirrors the original analogue design.

AF2-10/M Graphical EQ & FFT Plug-in
 
A versatile graphical EQ with a wide range of zero latency analogue modelled filters and realtime FFT display.
 
Many digital EQs, including those of some popular Digital Audio Workstations can have an artificially cramped filter response, especially at high frequency settings. This is often cited as a reason for the 'digital' sound of some equalizers.
 
Conventional solutions to this problem can be both CPU intensive and add extra latency or other artifacts.
 
By contrast, the AF2-10 uses innovative DSP algorithms to accurately model the frequency response of analogue filters, even at close to the limit imposed by the sample rate, without high CPU demand or additional latency.
 
Up to ten bands are provided covering a comprehensive range of filter types across the full 20Hz to 20kHz audio range together with a realtime FFT display featuring optional pre / post EQ monitoring and selectable slope compensation.
 
In addition, the package now includes the AF2-10M plug-in which provides all the features of the original AF2-10, together with built-in professional metering options for stereo PPM (IEC I & II) VU and dBFS monitoring pre / post the EQ.
