What is ProDSP

™

The DMP 64 features Extron’s ProDSP, a powerful digital signal processing platform based on a 32/64-bit floating point DSP engine. ProDSP provides an

extensive array of digital processing tools for audio system design, configuration, and commissioning. The DSP Configurator Software is the user interface

to ProDSP for full control and management of the DMP 64 and all of its DSP functions, including gain, dynamics, filtering, delay, ducking, loudness, and

feedback suppression.

An integral part of the DSP Configurator Software is the Graphical User Environment, which allows for quick and easy visualization of all input and output

signal paths inside a single window. Working within this user-friendly environment, an audio engineer or installer can clearly view and adjust all input

levels, audio DSP processing parameters, audio and video I/O ties, microphone mixing points, and output levels. To simplify these adjustments, SpeedNav

keyboard navigation ensures efficient and fast navigation through the Graphical User Environment, using just the keyboard on a laptop.

Highest Quality Converters Plus Floating Point DSP

The

DMP 64

features studio grade ADCs - analog-to-digital converters and

DACs - digital-to-analog converters using professional level 24-bit resolution

and 48 kHz sampling, fully preserving the integrity of the original audio signal.

The processing power of the 32/64-bit floating point DSP engine allows

for simultaneous audio processing algorithms within the same channel

and across multiple channels without compromising sound quality. Overall

latency – the normal delay of audio signals due to audio processing – is

always constant regardless of the number of active channels or processes, so

that the audio is kept in sync with the video. This powerful DSP engine also

delivers very wide dynamic range to prevent clipping and fully maintain audio

signal quality.

Fixed Yet Flexible DSP Architecture

The DSP Configurator Software features a fixed layout of DSP processing

blocks for each input and output signal chain. Each block in the Graphical

User Environment represents a Gain, Dynamics, Delay, Filter, Ducking, or

FBS - Feedback Suppression algorithm within the DSP engine. While this

architecture is fixed, each block offers flexible options and customizable

parameters. For example, the Filter block contains three, five, or nine

individual filters depending on the input or output, each of which can

be customized as parametric EQ, low pass, high pass, or bass or treble

shelving. Each block and each individual filter can be selectively bypassed.

Emulate and Live Modes

The DSP Configurator Software features an Emulate mode, which

provides complete audio system design while working offline on a PC.

When connected to the DMP 64, Live mode enables real-time control of

all settings, file updates and archiving, plus active metering of all input

and output channels. In Live mode, integrators can “push” all or part of a

configuration to the DMP 64 from the PC, while preserving the existing file.

Emulate and Live modes give audio system designers the flexibility to create

an entire project from their PC in advance of installation, and then, once they

are on site, use the same software to provide accurate system setup and

final commissioning.

One of the challenges of on-site sound system setup is

the lack of sufcient workspace for a PC and mouse. An

integrator or sound technician often has to work with a

laptop balanced on their lap, while trying to use the touch

pad to navigate through windows and menus of the DSP

software. Working in this environment can be time-

consuming and even frustrating.

SpeedNav simplies this task by allowing the use of only the

keyboard to access the software features through directional

keys and shortcuts. It is designed with A/V technicians and

sound system designers in mind. With SpeedNav, users

will experience faster, easier setup and system optimization

while working in the eld with laptop PCs to congure sound

systems and rene audio DSP settings.
