In this free video tutorial, Pro Tools Expert team member Julian Rodgers investigates the differences between the four EQ types available in the native version of the Sonnox Oxford EQ.
What is Q/Gain Dependency?
In an analogue equaliser there tends to be a change in the bandwidth of bell filters as different amounts of gain are applied. In vintage designs there often wasn't direct access to the Q of the filter and this interdependence was simply part of the character of the EQ. Some EQ designs are better regarded in some applications over others because of the way they feel in use and this is, at least in part, due to the Q/gain dependency of the equaliser's design. Control over Q/Gain dependency is a key feature of the Sonnox Oxford EQ and one which differentiates it from the majority of the alternatives out there.
5 EQ Types In Sonnox EQ
There are 4 EQ Types available in the Native version of the Oxford EQ and a 5th Type is only available for AAX DSP and TDM users. They are:
Type 1 - Minimal Q/Gain Dependency
Type 1 Displays minimal Q/Gain dependency (i.e. the Q doesn't change much as the gain changes). This is a precise style of EQ, similar to an SSL 4000.
Type 2 - Minimal Q/Gain Dependency in boost, constant Q in cut
Type 2 is identical to type 1 in boost but has a constant Q in cut, this makes it ideal for surgical cuts but avoids narrow Q values in boost, which often sound harsh.
Type 3 - Moderate Q/Gain Dependency
Type 3 Moderate Q/Gain dependency means that the Q increases (gets broader) at low settings, this makes the EQ sound more consistent in its behaviour. This type sounds similar to Neve EQs
Type 4 - High Q/Gain Dependency
Type 4 maintains an almost constant area below the EQ curve, meaning that the bandwidth gets much wider at low gain settings. This type of EQ is ideal for mixed material and mastering.
GML Option - AAX DSP and TDM Only
This 5th option has curves which are very accurately matched to the outboard analogue unit.
