MCP4k

The NGTC-MCP4k is an AES67 enabled multichannel audio processor for the Genesis Technologies™ audio distribution solution.

Picture Picture

The NGTC-MCP4k multichannel audio processor is capable of decoding all common digital audio formats delivering up to 8 AES67 channels of audio for processing by the NGTC digital signal processor.

The NGTC-MCP4k can be easily interfaced with 3rd party control systems via the control network port.

The NGTC-MCP4k is powered by a POE on the AES67 port. Its own Web UI is used to configure the AES67 interface. The additional LAN port is only used control. It can be configured by Web UI.

Application Note

Hardware

The NGTC-MCP4k is an AES67 enabled multichannel audio processor for the Genesis TechnologiesTM audio distribution solution. It is capable of decoding all common digital audio formats, delivering up to 8 AES67 channels of audio for processing by the NGTC digital signal processors. It can be easily interfaced with 3rd party control systems via the control network port. The small form factor makes it very flexible in its application.

Application 1 – In Room, Zone assigned

The MCP4k audio processor will be placed in the zone. It will accept local sources, central feed and the audio return from the TV (ARC,TOSLINK). The unit will decode, post process and sent out 8 discrete channels via AES67 to the audio network. The bass management, time alignment and channel mapping will be done in the DSP’s for maximum flexibility and performance. To have in the master zone a full 7.1 system while the master bath and dressing may run 2.0 or 1.0 no more an issue. The NGTC DSP super modules by Genesis TechnologiesTM enable efficient design and deployment of NGTC AVOIP systems, featuring the highest levels of functionality and performance.

Application 2 – In Rack, Zone assigned

The MCP4k audio processor will be placed in the rack and does accept the feed from the central matrix. Each zone has its own MCP. The unit will decode, post process and sent out 8 discrete channels via AES67 to the audio network. The bass management, time alignment and channel mapping will be done in the DSP’s for maximum flexibility and performance. To have in the master zone a full 7.1 system while the master bath and dressing may run 2.0 or 1.0 no more an issue. The NGTC DSP super modules by Genesis TechnologiesTM enable efficient design and deployment of NGTC AVOIP systems, featuring the highest levels of functionality and performance.

Application 3 – In Rack, Source assigned

The MCP4k audio processor will be placed in the rack, connected to each source and the output of the processor will run into the central matrix. Audio and Video will be separated from the beginning. The MCP4k will decode, post process and sent out 8 discrete channels via AES67 to the audio network. The bass management, time alignment and channel mapping will be done in the DSP’s for maximum flexibility and performance. To have in the master zone a full 7.1 system while the master bath and dressing may run 2.0 or 1.0 no more an issue. The NGTC DSP super modules by Genesis TechnologiesTM enable efficient design and deployment of NGTC AVOIP systems, featuring the highest levels of functionality and performance.

Installation

Picture Picture

  • 4 x HDMI inputs
  • 2 x mirrored HDMI outputs
  • 1 x Toslink digital input
  • 1 x AES67 network interface (POE) – please use UTP cabling
  • 1 x Control network interface – please use UTP cabling
Note

All connections to the MCP4k should be made before power is applied

• Attach any multimedia sources that will be used, to the inputs
• Attach the LAN network port to the control network switch, using an UTP CAT-5 cable
• Attach the AES67 network port to the AES67/Dante POE network switch, using an UTP CAT-5 cable.

Configuration

Setup interoperability between MCP4k and Dante devices

Caution

AES67 interoperability settings are required for every Dante device that should receive a AES67 stream

To enable your Dante devices to receive an AES67 stream, AES67 interoperability must be enabled. This is done by using Audinate’s Dante Controller, which can be obtained from the Audinate website or any other manufacturer specific software tool.

In Dante controller all your Dante devices that are connected to the network will show up automatically.

  1. Start the Dante Controller Software and wait for it to be synchronized with the network
  2. Select the “device info” tab in the software
  3. Double click on the DSP you would like to configure for AES67, a new window will open
  4. Select the “AES67 config” tab
  5. Enable AES67 mode and make a note of the Tx multicast prefix. You will need this number later, even if you are not using the DSP as a transmitter. This must be the same for all DSP’s that are ready for AES67.
  6. Reboot the Dante device
  7. This needs to be done with every Dante device that will receive an AES67 stream

Subsections of Configuration

Control Network Setup

Control Network Address Setup

The setup of the control network of the MCP4k will be done via it’s Web UI. It is self-explaining

Info

By default the interface is set to DHCP

Please make sure your computer network address is in the same network range to access the setup pages

Info

Default web UI username and password

admin

Info

To reset the control network address use the USR IOT tool

The tool does allow you to search and reset the network settings

USR Tool

AES67 Network Setup

AES67 Network Address Setup

To configure the AES67 network address use the built in Audiolan web UI. Your PC needs to be connected to the AES67 network and have its addressing set in the same IP range.

Info

By default the AES67 network interface is set to the static IP address (192.168.4.233)

Caution

To avoid an IP conflicts, connect one device after another and change each units IP to a different one

Note

Avoid any special characters and spaces in the device name

  1. Open a browser and enter the devices AES67 network address in the address bar, press enter
  2. Select the “General settings” tab in the web UI to change the devices IP address
  3. The NGTC-MCP4kR2 should have an IP and Subnet address in the same range as the Dante devices
  4. Apply all settings and reboot the device

Picture Picture

AES67 Stream Address Setup

Caution

The AES67 stream of each device needs to be configured to be received by the Dante/AES67 devices

Note

Avoid any special characters and spaces in the stream name

  1. Open a browser and enter the devices AES67 network address in the address bar, press enter
  2. Select the “Stream provider” tab in the web UI and uncheck the “Use automatic configuration” checkbox
  3. Make sure that the first 2 octets matches the Multicast Address Prefix given in the Dante Controller (239.69.xxx.xxx in the example below). Set the last 2 octets to unique values. always avoid duplicated IP addresses. Best practice is to set them to the same value as the last 2 octets of the AES67 network address
  4. Make sure that the “Activate” checkbox for the stream is checked
  5. Select the “Advanced” tab and ensure that the SAP browsing is enabled

Audio Routing using Audinate’s Dante Controller

Natively the audio routing can be done by using Audinate’s Dante Controller in case if its not auto configured by the DSP’s management software. In Dante Controller all your Dante and AES67 devices that are connected to the network will show up automatically.

The MCP4kR2 will be shown at the ‘‘Dante Transmitters’’ part, using its multicast address@hostname-HH-HH-HH where ‘‘HH-HH-HH’’ are the last three bytes of the devices MAC address.

Channel assignment

  • Make the audio connections in the Dante controller

Picture Picture

Audio Routing using Symnet Composer

In case of NGTC DSP hardware, the audio routing is done by using the Symetrix Symnet Composer. Please make sure all your Dante and AES67 devices that are connected to the network and are online. You might check this using Dante Controller.

Channel assignment

Create a 8 channel network AES67 receive module:

  1. In “Tools” open “Network I/O Manager”
  2. Select the corresponding bus and select “Edit Dante Bus”
  3. Check “External Network Device Name” and Browse AES67
  4. Pick the stream and Select AES67 Stream
  5. Insert the stream receiving module in the DSP’s configuration and connects its audio connections

Picture Picture

This will connect the MCP4kR2 AES67 stream to the DSP while going online. There is no need to use the Dante Controller to do the connection.
