User manual SONY OXFORD R3 EQ PLUG-IN

[. . . ] Control setting retention between instances, which allows switching between different EQ instantiations without losing control settings. Placing cursor over the centre of any control indicates current value settings without parameter change. Parameter values can also be displayed permanently if required. Selectable mouse mode, which provides relative rotary style control. [. . . ] If the GML8200 option is available, it appears as the fifth selection. 24. IN button. Applies the EQ function type selected by +/- push buttons in (22. ) The IN button light will go out if another EQ type is selected, indicating that the EQ remains unchanged until the IN button is depressed. 26. 8 Character display. Displays the function type selected by +/- buttons in (22. ). If the optional GML8200 EQ is available it appears as an additional selection in this display. 27. Overload indicator. Displays signal overload at the output of the EQ and Filter sections. The default mode for this function is latching, requiring click to reset. Clicking and holding on the overload area produces a pop-down menu that enables selection of either 2 or 5 second time out settings to facilitate initial EQ adjustment. 5 28. Options Popup Clicking on the Sony button produces a pop down menu where the operation of the plugin user interface can be customised. Display Values. Set to either `Changed' or `Always', this option controls whether the values for the knobs are displayed all the time - `Always' or only when the mouse is moved over them `Changed'. The `Always' option is useful if a ProControl or similar hardware controller is being used to adjust the plugin controls and the operator wishes to see the current value of a knob on the screen. This sets the approximate time that the over light will stay on for when the plugin has detected a fulllevel sample at it's output. `Clicked' means the light will stay lit until the user clicks on it with a mouse. The other two options will set the length of time in seconds before the over light goes out after a fulllevel sample is detected. This option sets the operation of the mouse to be either `Linear' ­ meaning the value increases or decreases by moving the mouse horizontally or vertically, or `Circular' meaning the knob value is changed by moving the mouse in a circular motion around the knob. The previous release of the Sony Oxford EQ plugin operated in linear mode only. Mouse rate control. Fine adjustments to any control setting can be achieved by pressing the `Apple command key' button before clicking on the control to be adjusted and holding this key down during the operation. 6 This rescales the control rate with the mouse movement so that very fine adjustments can be made. 6 Oxford EQ Specifications and Control ranges. All ranges and specifications apply equally to all available sampling rates.

Programme equalisers have expanded, beyond their original use as distance correction devices for film and vision, into highly creative tools that represent a leading part of the sound engineer's artistic palette. A great many EQ designs have been developed over the years that have been attributed with qualities that lend themselves to particular uses and sounds. The Oxford EQ plug-in is designed to be flexible enough to address as many of these generic types as possible from a single application, by presenting a variety of types to the user. The following pages are presented as a general explanation of many of the factors that affect EQ performance and to illustrate how we have addressed these issues with the Oxford EQ plug-in. Many types of EQ exist with many areas where they differ. One of the most important areas is the issue of control ranges and interaction. Whilst it is true that with a parametric unit with continuous controls (i. e. [. . . ] At maximum (blue plot), the Q control provides for an overshoot of half the total boosted gain, i. e. for +20dB total HF boost the maximum loss in the overshoot region will be ­10dB. The curves are symmetrical in cut and boost gain settings. 12 8 GML8200 option supplement. The GML8200 emulation is available as a cost option and the downloaded applications replace the Oxford EQ with new applications that include the GML8200 emulation. The EQ plug-in equipped with this option works in exactly the same way and includes all the features of the Oxford EQ and Filter section. [. . . ]
