Primary Mix Matrix - Extron electronics DMP 64 User Manual

Primary Mix Matrix

The DSP architecture contains a primary mix matrix that connects the mic/line inputs and
virtual bus returns to the line outputs. The DSP Configurator GUI provides control of
the primary mix matrix, used to set mix levels from the post processing inputs and post
processing virtual returns, to each line output bus. Each of the six mic/line inputs and
four virtual bus returns is connected to a mix-point for each of the four line outputs. In
general, mix levels are set relative to each other, achieving a desired blend of input signals
at an optimal output level, close to, but not exceeding 0 dBFS at the line output Volume
block level meter (while accounting for processing that may occur in the line output signal
chain).
Shown below is a drawing of the DMP 64 represented in the DSP Configurator, with a red
box indicating the primary mix matrix.
NOTE: Although the virtual bus send and Return lines, A-D, are shown as end points
From the primary mix matrix, any or all of the six inputs may be routed to any or all of the
four outputs. Any or all of the six inputs may also be routed to the secondary mix matrix.

Clicking a mix-point brings focus to that mix-point. Double-clicking a mix-point opens a
configuration dialog window with the following components:
The title above the fader reflects the input and output channel names for the mix-point.
The example on the left is the Input #1 to Output #1 mix-point.
in this block diagram, they are connected A-A, B-B, C-C and D-D.

• Mono Fader — sets mix level to the output bus. Gain range is -35 dB to +25 dB.
Fader behavior is identical to the input channel gain block described in the mic/line
input section with the exception that course adjustment (Page Up/Down) increases/
decreases in 5 dB increments.
• Mute — Mutes and unmutes the signal to the output bus.
• OK/Cancel — click
