Solid State Logic X-EQ - Manual (Page 5)

Thank you for purchasing the X-EQ plug-in for the SSL
Duende platform. X-EQ is a versatile and comprehensive
mastering grade parametric EQ plug-in built from the ground
up for Duende. It has an unprecedented clarity, smoothness,
and excellent high-frequency response.
The use of innovative coefficient generation and innovative
processing design provides superior performance that
surpasses analogue EQ in both artistic freedom and sound
quality. This plug-in may well provide all the different EQ
options you will ever need.
A total of 10 EQ bands are provided, split into dedicated HP
and LP filters, LF and HF shelves and 6 bell bands. A Parallel
EQ mode is also provided which recreates the characteristic
sound of an old parallel passive PEQ circuit built with
inductors and capacitors.
In addition to this, different filter types are provided
independently for each of the 10 bands. The HP and LP filters
have 5 different topologies available, the 6 bell bands each
offer 9 different characteristic shapes and the LF and HF
shelving filters offer variable Q. Together these cover the vast
majority of EQ styles currently popular amongst professional
users, including some legacy styles which are renowned for
their artistic capability and some unique designs only possible
in the digital domain.
Liberated from any analogue style control legacy, the X-EQ
graphical user interface will especially appeal to people who
like to see what they are hearing. The fully interactive EQ
display shows the exact filter shapes and resulting curves of
the different EQ bands, and a real-time spectrum analyser
allows you to see the effect of your EQ settings on the overall
frequency spectrum of the sound source. Extensive control
options include dragable EQ nodes, traditional mouse
parameter control and exact numerical entry.
The plug-in is available in both mono and stereo instances in
VST, AU and RTAS formats making it compatible with
virtually all audio software currently available on both PC and
Mac.
As with other Duende plug-ins, X-EQ is capable of operating
at 44.1, 48, 88.2 and 96kHz sampling rates, where a mono
instance at 44.1/48kHz occupies 1 Duende processing slot.
This figure is doubled for stereo use and doubled again for
88.2/96kHz operation.
