Mic ducking — Automatically reduces program audio when a microphone or other
•
incoming audio signal is detected, replacing the need for a separate audio ducking
processor.
• Studio grade 24-bit/48 kHz analog-to-digital and digital-to-analog converters —
Professional converters fully preserve the integrity of the original audio signal.
Fixed, low latency DSP processing — Input to output latency is a constant 4.5
•
ms within the DTP CrossPoint 4K, regardless of the number of active channels or
processes. Fixed, low latency processing keeps audio in sync with video, and prevents
distractions to the presenter resulting from delayed live audio.
• DSP Configurator Software — A powerful yet user-friendly PC-based software tool
for managing all audio operations of the DTP CrossPoint 4K Series. It enables complete
setup and configuration of digital audio processing tools on the DSP platform, as well as
routing and mixing.
Group masters — The DTP CrossPoint 4K Series provides the capability to
•
consolidate gain or mute control throughout the system. Gain or mute controls can be
selected and added to a group master, which can then be controlled by a single master
fader or mute control. Up to 32 group masters can be created.
• Soft limits provide optimal group master adjustment range — The group
master volume range can be limited using soft limits to maintain optimal minimum and
maximum levels when using external volume control. This prevents operators from
over or under adjusting levels when using Ethernet, USB, or RS-232 control. The DSP
Configurator Software provides quick drag-and-drop adjustment of soft limits from the
Group Controls screen.
• 32 DSP Configurator presets — Using the DSP Configurator Software, any or all
parameters for DSP processing, levels, AV matrix switching ties, and audio matrix
mixing can be saved as presets.
NOTE: When you save a preset using the Product Configuration Software, any of
the DSP Configurator settings described above that are associated with the audio
inputs and output involved in the preset are also saved as part of the preset.
Flexible matrix design provides output, virtual, and expansion routing options —
•
The DSP architecture of the DTP CrossPoint 4K employs an intuitive matrix design that
offers substantial flexibility in routing, mixing, and processing audio input sources. An
output matrix allows any of the four microphone inputs to be matrix mixed to any or all
of the four stereo outputs of the AV switcher block. If desired, any of the microphone
inputs or AV switcher outputs can first be directed into a virtual matrix, which routes
the inputs to eight virtual buses, before being mixed back into the output matrix. Virtual
buses allow inputs to be processed together as a group. The expansion matrix provides
signal routing between the DTP CrossPoint 4K Series and a DMP 128 processor linked
via the expansion port.
• Building blocks processor settings — A collection of pre-designed processor
settings optimized for a specific type of input or output device, such as microphones
and Extron speakers, with preset levels, filters, dynamics, and more. Flexible building
blocks are available on each row of DSP building blocks and allow system designers
to fully customize and save their own building blocks, further streamlining audio system
design and integration.
