Description

In essence, the SPNDNT is a full function DSP mixer and processor like other ASPEN models except that instead of analog I/O ports, it uses digital network Dante ports. The processor combines Dante networked digital audio with the ASPEN digital matrix to expand signal routing options. The on-board Audinate Brooklyn II module functions as a native Dante device using standard ethernet or AVB compliant switches.

The processor also handles the clock synchronization for the ASPEN equipment and the Dante network. If the processor is the Dante master, it generates the clock signal for the network and the ASPEN rack. If the processor is a Dante slave, it picks up the network clock and passes it on to the ASPEN system below it. Multiple Dante equipped devices will automatically discover one another and configure the Master/Slave relationship.

Redundancy, which is required in some applications, is accomplished by connecting to a secondary network that duplicates real-time audio traffic. If the primary network fails for any reason, the secondary network's audio continues without losing even a single sample.

Features:

  • Connects Dante networked audio with ASPEN processors
  • Up to 32 inputs and 32 outputs from the Dante network operate as native inputs and outputs in the 
    ASPEN digital matrix
  • Low latency, tightly synchronized transport of uncompressed audio over IP networks using 
    off the shelf switches
  • Simplified configuration management includes easy to use Dante features like automatic device discovery 
    and plug and play networking
  • Gigabit Ethernet transport
  • AVB Support
  • Redundancy via secondary network

Dante delivers a no hassle, self configuring, true plug-and-play digital audio network that uses standard Internet Protocols over Gigabit Ethernet. Patent-pending Dante technology distributes digital audio plus integrated control data with sub millisecond latency, sample-accurate playback synchronization, extreme reliability and high channel counts.

NOTE: The Dante interface will also operate over 100 Mbps connections for some applications, however, this is not sufficient bandwidth for ASPEN processors due to the high channel count, so gigabit connections are required.

Plug-and-Play Networking for Media Professionals
With Dante's Zero configuration protocol, you won't need a networking specialist to enter numerical IP or MAC addresses, or set up DNS or DHCP servers. Dante makes networking a true plug-and-play process with automatic device discovery and system configuration. Dante enabled devices find each other on the network and will configure themselves, so you can skip those complicated, error-prone set-up procedures. Instead of œmagic numbers, you label networked devices and their input and output signals with names that make sense to you.

IP Standards Based Technology
Dante is built on global networking standards including Internet Protocols not just Ethernet. With true IP routing, Dante technology works as an IT network capable of transporting professional quality audio and high definition video with no limits on your layout options. Dante delivers sample-accurate playback synchronization, even over multiple switch hops. Latency is extremely low whether you choose to run your Dante network with fixed latency or optimized latency. Dante makes it easy to set up robust, flexible digital audio networks with performance that scales with your network.

Media Networking over Existing Infrastructure and Hardware
Dante runs on inexpensive off-the-shelf computer networking hardware, and does not require dedicated network infrastructure. Ethernet switches transmit Dante
digital media streams alongside ordinary data traffic, so you can integrate professional media operations into properly designed pre-existing networks. And with Dante Virtual Soundcard (DVS), your Mac or Windows computer looks and acts like any other Dante-enabled device.

Just plug in to the standard Ethernet port to use digital audio processing, recording or playback software on the network.

Sample Accurate Timing with Inaudibly Low Latency
Dante uses audio independent, high accuracy network synchronization standards to ensure all Dante devices are synchronized at all times. Sample accurate playback with extremely low latency and jitter is achieved without limiting your audio sample rates and network layout options.

Summary of Dante Benefits
Dante is a high performance digital audio networking solution that offers many benefits to users and manufactures of equipment for Live Sound, Install, Recording or other Pro Audio markets.

  • Plug-and-play technology - automatic discovery and simple signal routing
  • Reduced Cost & Complexity- No special skills required to set up audio networking
  • Sample accurate playback synchronization
  • Lowest latency available from any networking technology
  • Add/remove/rearrange components at will
  • Deterministic latency throughout the network
  • Support mixed bit depths and mixed sample rates over one network
  • Scalable, flexible network topology supporting a large number of senders and receivers
  • Supports mix of 100Mbps, 1Gbps, through 10Gbps networks
  • Supports a single integrated network for audio, video, control, monitoring
  • Uses inexpensive, off-the-shelf computer networking equipment
  • Direct connection to PCs for multi-channel recording, processing and playback using a Dante Virtual Soundcard for both PCs and Macs
  • AVB Ready

Functions Added by SPNDNT Processor
Automatic mixing: auto, direct, override, background and phantom modes for use in sound reinforcement, recording and mix-minus applications.
Gain adjustment: to match levels from different audio signal sources.
Delay: to time align audio from different signal sources.
