eq and filters14As standard, the OXF-R3 offers five-band, fully parametric, EQ withseparate HP and LP filter sections on Full input channels. The StereoReturn channels have three-band EQ. Several modes are supported,featuring different relationships between factor and gain. The optionalDMSK-R3001 Software emulates the GML 8200 equaliser. The EQ andfilters are controlled from the dedicated ‘Equaliser & Filters’ paneland the resulting frequency curve is displayed on the associated GUI.The panel is designed to be very intuitive and fast to operate, withindividual switches and rotaries for every EQ and filter function.The standard EQ is extremely powerful, with the gain of all bands fullyadjustable over a range of ±20 dB and with Q adjustable between 0.5and 16. Frequency ranges are carefully selected for each band,creating an extremely ‘musical’ device equally capable of deliveringsubtle or radical tonal changes with any source material.The OXF-R3 permits EQ parameter changes to be made smoothly andevenly with an analogue console-like feel. This glitch-free performanceis made possible by real-time parameter interpolation that preventsabrupt ‘steps’ in the response of the console’s EQ sections.The Low and High bands can switch between Bell and Shelvingprofiles. In the Shelving mode, the Q control changes to provide anovershoot/undershoot control mimicking the response of popularoutboard EQ devices. The console is supplied with two EQ memoriesfor every channel, selected from the A and B switches on the panel.These memories allow the operator to experiment, without losing theprevious settings. During mixing an alternate EQ can be recalledeither manually or by the console automation.Equaliser & Filter PanelThe EQ Range control allows the limits of cut and boost on eachchannel to be adjusted between ±20 dB and 0 dB. As with all othercontrols on the console, this adjustment is completely glitch-freewhich permits complete EQ settings to be ramped in and out. The EQRange control also allows the cut and boost limits to be reducedthereby increasing the resolutionfor ultra-fine adjustment.The High and Low Pass filters onthe Full channels are also highlyversatile. The cut-off frequencyis continuously variable andthe filter slope can be selectedbetween 6 dB/octave and 36dB/octave in 6 dB steps.Dynamic automation of the EQ and filters provides new creative toolsfor the studio. For example, the operator can ‘de-ess’ a vocal bydynamically automating the high frequency band against time code.Standard EQ mode GUIOptional DMSK-R3001 Software EQ mode GUI
