Virtual Bus Returns; Mix Matrixes; Line Outputs - Extron electronics DMP 64 User Manual

• Delay (DLY) – channel delay can be set by feet or meters modified by an air
temperature parameter, or by direct time insertion from 0 - 200 ms.
•
Ducking (DUCK) – mic ducking can be set up using the ducking dialog box.
• Gain (GAIN) – Pre-mixer matrix gain control with a range of -100 to +12 dB.

Virtual Bus Returns

Virtual return elements from left to right are as follows:
•
Filter (FILT) – up to three frequency filters can be inserted in any combination of High
Pass, Low Pass, Bass & Treble shelving, or Parametric EQ.
• Dynamics (DYN) – a single dynamics processor can be inserted from a choice of
AGC, compressor, limiter, or noise gate.
• Loudness (LOUD) – adjusts the signal to compensate for changes in human
perception at the high and low end of the hearing curve using a predetermined filter
curve in response to the sum of the virtual return gain and the Calibration Adjustment
slider value.
•
Gain (GAIN) – mono gain control with a range from -100 to +12 dB includes mute
button.

Mix Matrixes

The dual matrix contains 76 mix-points, each containing a single fader with a range of -35
to +25 dB, plus a mute control. The 76 mix-points are grouped into two matrixes. Dual
matrix features are as follows:
• Primary Matrix – a mic/line input section and a virtual bus return section feed the
primary matrix, which routes incoming signals to the line outputs.
•
Secondary Matrix – a mic/line input section and a virtual bus return section feed the
secondary matrix, which routes to the virtual bus sends.

Line Outputs

Line Output elements from left to right are as follows:
• Trim (TRIM) – Post-mixer mono trim control with a range of -12 to +12 dB
• Loudness (LOUD) – adjusts the signal to a predetermined filter curve in response to
the sum of the line output Volume value and the Calibration Adjustment slider value
to compensate for changes in human perception at the high and low end of the
hearing curve.
• Delay (DLY) – channel delay can be set by feet or meters modified by an air
temperature parameter, or by direct time insertion from 0 - 200 ms.
•
Filter (FILT) – up to nine frequency filters can be inserted in any combination of High
Pass, Low Pass, tone (Bass & Treble shelving), or parametric.
• Dynamics (DYN) – a single dynamics processor can be inserted from a choice of
AGC, compressor, limiter, or noise gate.
• Volume (VOL) – a mono fader adjusts output volume from -100 to 0 dB and includes
a mute control. A polarity switch (+/-) is provided and a meter displaying output audio
level in dBFS.
