ACM530X1 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. Input Trim
 
The Input Trim control adjusts the signal level by as much as +/- 6dB as it enters the reverb. It also varies the amount of 'drive' to the plate emulation.
 
2. Pre-Delay
 
The Pre-Delay control delays the signal by up to 250ms before it enters the reverb. The control is fully interpolated and adjustable to sub-sample accuracy.
 
3. Time
 
The Time control sets the time required for the reverb to decay. Also known as RT60, it is the time taken for the reflections to decay by 60dB.
 
Note: There can be some interaction between the time and damping controls.
 
4. Damp
 
The Damp control adjusts the amount of high frequency (HF) damping applied to the reverberated signal. Similar to the mechanical damping, in part used to control the reverb time in mechanical plate reverbs.
 
5. Width
 
The Width control adjusts the width of the stereo image. Similar to plate reverbs in which a pseudo-stereo reverb signal is created from a mono effect feed by adjusting the mix between two adjacent receiver transducers.
 
6. Clip LED
 
The ACM530X1 emulates a mechanical plate reverb. Such devices use transducers coupled to a large metal plate to generate the reverb effect. The Clip LED warns if either the virtual drive or receiver amplifiers are being overloaded by the signal. Typically this only occurs at very high levels - and can be used in some cases as a creative effect, or to add some extra harmonic drive to the sound.
 
7. Wet
 
When active, the wet switch diverts only the effected (wet) signal to the output instead of a blend of effected and clean (wet / dry). This mode is useful if the reverb is placed on a general 'reverb buss' within a DAW. In such situations the dry signals are sent to the reverb buss, and the returned reverberated sound mixed with the original signal using the DAW faders instead of the plug-in's Mix control.
 
8. Mix
 
The Mix control adjusts the relative levels of effected (wet) and clean (dry) signal. For the control to be active, the Wet switch must also be switched out.
 
9. Output Trim
 
The Output control adjusts the signal level (combined wet / dry or wet-only) by as much as +/- 6dB to aid level matching.
 
10. Mute
 
When enabled, the mute switch mutes the input signal to the reverb. This can be useful to momentarily kill the input in order to audition the reverb decay and other parameters.
 
11. Effect In / Out
 
With the switch illuminated the reverb is placed in the signal path and will begin affecting the signal. With the switch off, the signal will pass through the effect unaltered (either by the effect or the input / output gain settings).
