The Extron DSP Configurator software is required for configuring routing, mixing, DSP parameters, and presets. It is available for download from the Extron website.

How many audio inputs and outputs does the DMP 64 Plus have?

The DMP 64 Plus features 6 balanced analog audio inputs and 4 balanced analog audio outputs, all on captive screw connectors.

What is the power consumption of the DMP 64 Plus?

The unit consumes 15 watts maximum. It operates on 100-240 VAC, 50/60 Hz, and features an internal power supply.

Is the DMP 64 Plus rack-mountable?

Yes, it is designed for 1U rack mounting in a standard 19-inch rack. Included mounting brackets ensure secure installation.

How do I update firmware on the DMP 64 Plus?

Firmware updates are performed via the Ethernet port using the Extron DSP Configurator software. Download the latest firmware from Extron's website and follow the update wizard.

Can I use unbalanced audio with the DMP 64 Plus?

The inputs and outputs are balanced but can accept unbalanced signals if you connect signal to the positive (+) terminal and ground (-) to sleeve. Ensure proper wiring for best performance.

What are the input impedance and output level?

Input impedance is >10 kΩ balanced; output level is +24 dBu maximum balanced (typical +4 dBu nominal).

1.0 Introduction

This document provides a single reference for answers to Dante questions that commonly come in to Extron support staff. Check back for updates as this document will be revised as needed.

2.0 Dante Flows

The channels of audio going into and out of a Dante device are organized into groups of one to four channels, called Flows. Dante devices have limits to the number of input Flows and output Flows, depending on the type of Dante technology (chipset) utilized in the device. A single Flow cannot have its channels divided or distributed among multiple devices. Therefore, it is advisable to plan for channel connectivity between devices while considering the number of Flows available per device and the layout of device to device connectivity.

The table below shows the number of Flows available in Extron Dante-enabled products.

Flow Examples

Four channels are routed to an AXI 44 AT via Dante from two devices. The four channels are available at the analog outputs of the AXI 44 AT. This is possible because the AXI 44 AT has two Receive Flows. [Figure 1]

    A["Device 1"] -->|2 Channels\n1 Flow| C["Dante Network"]
    B["Device 2"] -->|2 Channels\n1 Flow| C
    C -->|4 Channels / 2 Flows| D["AXI 44 AT"]

[Figure 1] This application will work

If those channels originate from more than two transmitting devices, the number of Receive Flows available on the AXI 44 AT would be exceeded. This application will not work. [Figure 2]

    DTE_Dante_Dante_Network -->|1 Channel / 1 Flow Per Device| DTE_Dante_Dante_Network

3.0 Unicast and Multicast

By default, Dante routing is done by unicast Flow, meaning that the routing of up to four channels between two devices uses up a single unicast Flow [Figure 3]. A unicast Flow cannot be routed to multiple Receivers. With unicast routing, extraneous network traffic is typically avoided.

graph LR
    Device1["Device 1"] -->|1 Flow| DNTD["Dante Network"]
    Device2["Device 2"] -->|1 Flow| DNTD
    DNTD -->|1 Flow| Device3["Device 3"]
    DNTD -->|1 Flow| Device4["Device 4"]

[Figure 3 – Two Unicast Flows]

In cases where a single Dante Transmitter must be routed to many Dante Receivers, having a separate unicast Flow per Receiver not only uses up Flows but also increases network bandwidth use. In these cases, creating a single multicast Flow is recommended for routing to many Receivers without using up Flows [Figures 4 & 5]. Dante Controller will present a message when a Multicast Flow may be advantageous based on the routing defined.

Multicast Flows are also useful when transmitting the same audio to more than two Receiver devices

graph LR
    A["Device 0"] -->|1 Flow| B["Dante Network"]
    B --> C["Device 1"]
    B --> D["Device 2"]
    B --> E["Device 3"]
    B --> F["Device 4"]

[Figure 4 – Multicast Flow]

To create a multicast Flow:

1. Double-click the device in the Routing tab or CTRL-D
2. Click the Create a new multicast flow button
3. Check the box for each channel to be included
4. Click Create
