Intuitive Graphical User Environment
The DSP Configurator Software feature a Graphical User Environment that offers a clear view of all input and outputs, audio processing blocks, audio and video routing ties, and microphone mixing points in a single window. This allows a designer or installer to quickly view all audio and video-related activities without having to access sub-windows or submenus.

I/O Ties
The Graphical User Environment of the DSP Configurator Software provides a clear view of all audio and video I/O ties. using the mouse or the keyboard, ties for audio or video signals, or both can be created, modified, or deleted in real-time. They can then be saved and recalled as presets within the DSP Configurator Software. Presets can also be recalled from the MPX Plus 866 A front panel, through RS-232 serial control, or via IP Link Ethernet control.

Dynamics
The DSP Configurator Software enables fine tuning and adjustment of the dynamics of all incoming and outgoing signals from the MPX Plus 866 A. Two Dynamics processing blocks are available for each input and output. These blocks can be selected and customized to provide automatic gain control compression, limiting, or noise gating.

Input and Output Filters
The Filter block offers three customizable filters for each line input, five for each mic input, and nine for each of the six outputs. A filter can be selected from parametric EQ, low pass, high pass, or bass and treble shelving options. Customizable parameters include frequency, roll-off slope, boost/cut, and Q, depending on the specific filter.

Feedback Suppression
The FBS - Feedback Suppression block is used to counteract the ringing due to frequencies cycling out of control through the microphone and speakers. The feedback supression processor for the MPX Plus 866A engages up to twenty notch filters with adjustable Q. Fefteen of the filters and dynamic, and the processor uses these to automatically detect and then eliminate the ringing. Five additional fixed filters can be adjusted manually or transferred from the dynamic filters.

More
Delay
A Delay processing block is available for each input and output. Delay is adjustable up to 200 ms, and can be selected in units of time, feet, or meters. A temperature parameter is available for distance adjustments.

Mic/Line Matrix Mixer
The DSP Configurator Software is also used to manage and control mic/line audio matrix mixing. Each mic/line input can be mixed into each of the six available line outputs, with dedicated stereo mix level and muting controls at each node.

Alternate I/O Views
With just the touch of a function key, the user can toggle between Audio Only, Video Only, or Audio & Video I/O views. The DSP Configurator Software allows for live changes to audio and video routing ties using keystrokes or a mouse. In Video Only I/O view, video-specific options are a vailable inducing composite and S-video transcoding, RGB output delay, and video output muting.

More
Ducking
The Ducking block is used to give priority to a specific microphone by automatically attenuating the levels of other microphones and program sources, whenever the priority microphone is active. Ducking setup is performed for all mic/line inputs on a unique global setup page. An extensive range of customizable options for ducking are available.
