Extron electronic Extron Electronics Music Mixer DMP 44 LC User Manual

The diagram below shows the signal flow and DSP processing per signal chain. Signal 
chains and the matrix are described in the following sections.

All signal routing, processing, and level control (gain/trim/volume), are accomplished using 
software control from a PC connected to the DMP 44 LC via the USB configuration port 
or the RS-232 port. The DSP Configurator program provides complete control while SIS 
commands provide more limited control.
This section describes the signal processing including parameter ranges, and how to 
mix inputs and outputs using the DSP Configurator control program. To install the DSP 
Configurator program (see the “

• 

Gain (GAIN) — Mono gain control with a range from -18 to +24 dB includes a mute 
button. Step resolution is 0.1 dB. A polarity switch (+ or -) is provided. Gain control is 
provided pre-meter and mute control is provided pre-meter.

• 

Filter (FILT) — Up to three filters can be inserted in any combination of High Pass, 
Low Pass, Bass & Treble shelving (tone), or Parametric Equalizer. 

• 

Dynamics (DYN) — One compressor per block per channel. Dynamics processors vary 
the dynamic level (the range of loudest to softest signals). 

• 

Ducking (DUCK) — One ducker per block, per channel. Each ducker can function as 
either a source or a target. Three levels of priority are available, where a ducker can 
function as both a source and a target (as an example, one source may be ducked by 
another source, and also trigger ducking on program channels).

• 

Gain (GAIN) — One pre-mixer gain control per channel with a range of -100 dB to  
+6 dB. The step resolution is 0.1 dB.
