ACM500X1 Product Operating Guide
 
Access to plug-in parameters is provided by a fully resizable graphical user interface. Your host application may also provide access to parameter adjustments and additional configuration. Graphical User Interface
 
The plug-in settings are adjusted by clicking and dragging on the rotary controls or buttons. Some controls may have detents – these manifest themselves as areas in the rotation where the reluctance to move is increased such that you have to drag them a bit harder. They are intended to behave similarly to real controls which may have a 'click stop' at 0dB for example.
 
You can also adjust the controls by placing the mouse pointer over them and using the scroll wheel. In this case the detent has no effect.
 
Control Modes
 
The control mode determines the way in which the rotary controls respond to mouse movement. This can normally be configured via the host application preferences. Please refer to your host application documentation for details.

• Circular. In this mode, clicking on a control will move it immediately to the mouse pointer’s angular position. To adjust the control, drag the mouse pointer in a circle or an arc.
• Relative Circular (Default). This is the default mode unless changed by host application settings. Similar to circular mode, however moving the mouse will adjust the control relative to its current setting.
• Linear. In this mode, the control responds to vertical mouse movement. Drag up to increase the value, turning the control clockwise, or down to decrease the value, turning the control anticlockwise.

In all modes, double clicking the centre of a control will return it to its default position.
 

Control Functions
 
1. High Frequency Boost / Cut - HF dB
 
The HF dB control sets the amount of boost or cut applied to frequencies above the point selected by the HF Hz control, covering a range of +/-15dB.
 
2. High Frequency Cutoff - HF Hz
 
The HF Hz control sets the point above which the high frequency boost or cut takes place. Turning it clockwise increases the frequency, turning it anticlockwise decreases the frequency, covering a range from 4kHz to 8kHz.
 
3. Mid Parametric Boost / Cut - Mid dB
 
The Mid dB control sets the amount of boost or cut applied at the centre frequency selected by the Mid Hz control, covering a range of +/-12dB.
 
4. Mid Parametric Q - Mid Q
 
The Mid Q control determines the spread of frequencies affected by the mid-range boost or cut. The fully anticlockwise position, (maximum Q) selects a narrow range, while the fully clockwise position (minimum Q), selects a broader range.
 
5. Mid Parametric Frequency - Mid Hz
 
The Mid Hz control selects the centre frequency at which the mid-range boost or cut takes place, covering a range from 200Hz to 4kHz.
 
6. Low Frequency Boost / Cut - LF dB
 
The LF dB control boosts or cuts all frequencies below the point selected by the LF Hz control, covering a range of +/-15dB.
 
7. Low Frequency Cutoff - LF Hz
 
The LF Hz control sets the point below which the low frequency boost or cut takes place. Turning it clockwise increases the frequency, turning it anticlockwise decreases the frequency, covering a range from 100Hz to 200Hz.
 
8. High-Pass Filter - HPF
 
The HPF switch places a 75Hz high-pass filter into the signal chain. This can be used to help tame subsonic frequencies, low frequency rumble, or mechanical noise, especially when also applying low frequency boost.
 
9. Effect In / Out
 
This is the plug-in bypass switch. With the switch on, the plug-in will be in the signal path. With the switch off, signals pass through unaffected.

3. Free Demo Limitations

• Every 60 seconds the plug-in will fade to silence momentarily. To remove this limitation you will need to have purchased a product activation code.
• To remove the demo limitations, open the plug-in in your host application and click the lock button at the top left of the plug-in GUI to open the license entry dialogue. Type (or paste) your product activation code into the text box. You will then need to restart your host application to complete the process.
