GENELEC 9401A Multichannel Audio Over IP Interface

Introduction

Congratulations and thank you for purchasing the Genelec 9401A multichannel audio-over-IP (AoIP) interface. This manual addresses the setting up and use of the Genelec 9401A intended for use with 7300 Series subwoofers. The Genelec 9401A enables Smart Active Monitoring (SAM) monitors and subwoofers to receive multichannel audio presentations using standard AoIP networks. The 9401A offers 16 channels of AES-EBU digital audio feeds for SAM monitors and a dedicated AES/EBU interface for 7300 series Smart Active Monitoring (SAM) subwoofers, as well as an auxiliary AES/EBU output for supporting monitoring systems, such as headphones.

The 9401A enables the monitoring of immersive digital audio, supporting monitoring layouts up to 9.1.6 configuration when the low frequency effects (LFE) channel is also used. The auxiliary AES/EBU output can be used to connect, for example, an additional stereo monitor system or headphones when a digital-to-analog interface device and a headphone amplifier is used. Genelec’s energy-saving Intelligent Signal Sensing (ISS) function automatically puts the 9401A into a power-save state when no AoIPstream is present. The waiting time before activation can be configured using Genelec Loudspeaker Manager (GLM) software. WhenISS is on your monitoring system will remain ready for action and the 9401A will consume less than 4.5 watts of power. The interface will wake up and switch to normal operating mode when it senses an AoIP stream.

This 9401A is supplied with:

• Mains cable
• 5 m GLM network cable
• Quick Setup Guide
• Operating manual via QR code

The 9401A uses in addition a standard CAT cable for the IP network connection.

Installation

We strongly recommend switching off/ disconnecting mains power from all system devices before connecting signal cables.

Connections
Pay attention to the GLM network and Ethernet connectors. The GLM network uses the 8P8C (RJ45) connector but is not compatible with Ethernet or Power over Ethernet (PoE). The mains input supports a wide voltage range (100-240 VAC, 50-60 Hz). If the mains power is provided by a generator, inverter or a low-quality UPS device, we recommend using a harmonic filter to reduce the unwanted harmonic distortion.

The two digital audio stream inputs for ST2110, AES67 or Ravenna digital audio stream uses a standard 1000BASE-T compatible network interface with an RJ45 connector. The two inputs offer redundancy and can be configured for fast and seamless hand-over in case of the failure in the primary stream input. When the audio content in the stream carries a low frequency effects (LFE) channel, the 9410A is configured to extract the correct channel as the LFE content and assign the LFE content to the AES/EBU output and subframe by using the GLM software.

The multichannel audio output for the monitors uses one DB25 connector to deliver 8 AES/EBU audio signals, carrying 16 channels of audio. The output is a bitto- bit copy of the stream content audio signals, so the outputs retain the original signal quality without modification. When used, the LFE signal is output using the subwoofer interface and is also available through the DB25 connector, meaning that the LFE content is available for any device connected to this output. The content of the multichannel audio output is configured using the HTTP web interface. The digital audio output for the subwoofer is a single male XLR connector, which uses an AES/EBU cable to carry the sum of all the main channel inputs over one AES/EBU subframe and the LFE channel, if used, over the other AES/EBU subframe. A GLM Kit or SAM Reference Controller (RC) and Genelec.

Loudspeaker Manager (GLM) software is required to use the 9401A with 7300 Series subwoofers. The AES/EBU output on 7300 Series subwoofers enables the daisychaining of additional SAM subwoofers to increase the capacity of the system’s low frequency acoustic output (SPL). To make this possible, GLM software will align the playback of the complete subwoofer system with the rest of the monitoring system. The 9401A includes two GLM Network connectors for management using Genelec Loudspeaker Manager (GLM) software. The auxiliary digital audio output is a single XLR connector. It delivers two channels of audio. The content of the auxiliary output is configured using the HTTP web interface. The 9401A includes two GLM Network connectors for management using Genelec Loudspeaker Manager (GLM) software.

Redundant IP Network Input

The 9401A offers two network interface connections. This enables redundant connectivity following the ST2022-7 specification. The 9401A can be connected to two separate networks, so that audio streaming is seamlessly switched over if the primary IP network is compromised. Refer to the Web interface function reference for additional information on the network interface settings. The primary network interface is selfconfiguring by default. This means that the 9401A will automatically assign an IP address to itself without DHCP or DNS servers. The assigned IP address is visible in GLM. It will advertise its services and be discoverable through Bonjour, Avahi or similar implementations. For discovery, registration and control in ST2110 networks, 9401A supports the NMOS IS-04 and NMOS IS-05 interface specifications. The secondary network interface is set in switched mode by default. IP Packets entering the primary port will be forwarded to the secondary port, allowing a second device to be connected without using a separate network switch. It can be configured using the web interface, which can be accessed through GLM. Both network interfaces support zeroconfiguration, DHCP or static IP operation. The input connector of the 9401A follows the 1000Base-T standard for Gigabit Ethernet. Slower transmission speeds (10Base-T, 100Base-T) are not supported. Use of CAT 5e cabling or better is necessary.

Selection of IP switch

The 9401A is fully compatible with standard Gigabit Ethernet and IP switch technology. Genelec recommends using a managed switch. Managed IP switches offer the ability to configure, manage and monitor the local area network, typically using a web browser user interface, and this helps in creating a well working system. The IP switches shouldsupport QoS and multicast groups. Differentiated services (DiffServ) typically implement QoS prioritization of IP traffic. DiffServ marks IP
packets according to priority. In response, IP switches can prioritize media traffic to improve system performance. Differentiated services code point (DSCP) markings in the IP packet headers are sensed by the QoS capable IP switch. Multicast groups can be used to reduce traffic in large networks byforwarding data only to the devices that are set to receive it. Genelec does not endorse certain IP switch brands as the 9401A works perfectly with all high-quality standard IP switches with these capabilities. Use of 1 Gbps (Gigabit) or faster IP switches is mandatory.

Network Structure
For redundant connectivity, Genelec recommends a spine-leaf architecture. Otherwise, a star architecture is recommended. IP device ports should not be daisy chained to several IP devices. Each IP switch must have its own IP address. The 9401A can act as an IEEE1588-2008compliant clock source for the ST2110, AES67 or Ravenna network using the Precision Time Protocol version 2 (PTPv2). The PTP on 9401A is fully configurable through the web interface. Refer to the Web interface function reference for additional information on the PTP settings. Audio-over-IP requires the use of a cable-based LAN network. Low-latency uncompressed audio-over-IP streaming is not feasible over WLAN.

ST2022-7 Setup
ST2022-7 support is enabled by selecting the “Multi-Interface mode” option under Network in the web interface General settings page. The two interfaces should be configured to use different IP address ranges to avoid address conflicts. Changing the interface settings requires a reboot of the device. The 9401A will automatically detect a ST2022-7 stream source and seamlessly switch over if one of the Ethernet links is disconnected.

Table 2. Front panel indicator light functions

Dante Compatibility
9401A can interoperate with Dante systems using the AES67 mode. This must be enabled in Dante systems that connect to 9401A to enable audio to pass. See Table 1.

Output Cabling
The AES59 standard offers a configuration to deliver 16 channels of digital audio in one direction. This configuration is used in the output DB25 connector of 9401A. The audio output in 9401A is intended for connections to monitors. The recommended cable for this connection is an 8 x XLR male fan-out cable following the AES59 pinout, also known as the Tascam analogue pinout. For example, an Avid cable type DB25-XLRM DigiSnake can be used. In addition, AES/EBU XLRto- XLR cables are needed to extend the  signals from the snake output onwards to the monitors.

The AES59 standard output connector pinout of the 9401A is shown in Figure 5. We strongly recommend that a high-quality AES/ EBU digital audio cable be used.

Controls and Indicators
The 9401A’s front panel features a power switch with a power-on light as well as nine active-connection indicator lights for the AES/EBU outputs. The 9401A is configured using Genelec Loudspeaker Manager (GLM™) software. Please refer to the ‘Use With GLM Management Network’ section below for details. While editing the 9401A settings in GLM, the interface’s power-on light will blink continuously. A lit light indicates that the corresponding AES/EBU is available for output. If an output light is off, there is an AES/EBU data issue or there is no valid AES/ EBU audio. See Table 2 for a list of indicator lights and their functions.

Troubleshooting

If there are issues with audio transmission such as cuts or latency peaks, please check the following common issues. For additional information on how to perform each step, consult the manufacturer documentation or a technician.

• Processor usage of the connected computer. If the usage is at over 75 %, there is a risk of cuts in transmission. Attempt closing unnecessary background programs.
• Power saving settings of the processor or the Ethernet adapter. Attempt disabling these settings or setting the computer to high performance mode. If using a laptop, avoid using battery power and run on mains power instead.
• Antivirus and firewall settings. Make sure that the antivirus is not interfering with the streaming programs, and that the necessary firewall rules are set.
• Buffer length of the transmitter or receiver. Attempt increasing the buffer length or setting additional safety playout delay in the web interface general settings. If using different Ethernet adapter models in ST2022-7 mode, increasing the buffer size might be necessary to avoid cuts between switching.
• Other Ethernet or wireless adapters (Bluetooth, Wi-Fi). If these are active at the same time with the Ethernet adapter used for audio transmission, latency peaks may occur. Attempt disabling all other network and wireless adapters. An active internet connection on the streaming Ethernet interface may also cause latency peaks.
• For the lowest latency, a network adapter with hardware PTP timestamping support should be used.

Configuration and Management Using GLM and the HTTP Web Interface

The 9401A is set up using Genelec Loudspeaker Manager GLM™ software, using GLM’s Management Network. Advanced setup is done via an HTTP web interface. The web interface can be accessed by pressing the URL button in GLM settings for the 9401A. Refer to the Web interface function reference for additional information. More information about GLM is available in the SAM System Operating Manual.

Connection

Configuration consists of the following steps:

• Connect the IP network to the primary Ethernet network interface.
• Set up a digital audio stream in the ST2110, AES67 or Ravenna formats.
• Configure the audio source to connect to the 9410A device, for example using the web interface (Web interface function reference) or ANEMAN software.
• Connect ‘AES OUT 1-8’ to a fan-out cable and continue with XLR-to-XLR cables to each monitor. Please use cables intended for carrying AES/EBU digital audio. We strongly discourage the use of standard analogue microphone cables as this may reduce system performance.
• Connect the ‘SUBWOOFER LINK’ output to the ‘DIGITAL IN’ connector on a Genelec 7300 Series subwoofer.
• Connect the ‘AUX STEREO OUT’ output to stereo monitors or headphones through a digital-to-analog converter and a headphone amplifier.
• Connect CAT 5 (RJ45) GLM network cables between the 9401A, every monitor and subwoofer. Finally, connect to the GLM Adapter device (see Figure 2). The connection order of the other devices is not important. Connect the GLM Adapter device to your computer via USB.
• Install and run Genelec Loudspeaker Manager (GLM) software. All devices appear in GLM software monitor stack. Move devices from the monitor stack onto GLM’s honeycomb grid, including the 9401A. You may want to drag and drop the 9401A icon close to the subwoofer connected to it (see Figure 6). When using multiple 9401A devices, you can identify a 9401A by clicking the 9401A icon in GLM, causing the associated 9401A device front panel power button light to blink.

Configuration
Configuration of the 9401A using GLM software has the following steps:

• Select the ‘Input Signal Type’ for the monitor Group to be ‘AES/EBU Digital’. Then, set the group status to ON state and the 9401A devices become active.
• Select the AES/EBU outputs in the 9401A to enable them. Note that you need to configure the audio streams. (see section Setting Up Audio Streams)
• Set the ‘AES/EBU Digital Input Mode’ to ‘Multichannel’ in the 7300 series subwoofer settings.
• In the ‘LFE Channel’ drop-down, select the AES output and the subframe that carries the LFE channel audio.
• Select the ‘+10 dB’ setting in the subwoofer configuration if the LFE channel audio requires the 10 dB boost in the subwoofer relative to the main audio channels.
• When all 9401A units in the system are set to ‘Group Off’ state, the ‘AES/EBU Digital Input Mode’ in all 7300 series subwoofers switch the AES/EBU digital stereo audio input to a standard stereo audio input.

Setting Up Audio Streams

While GLM is used for managing the LFE and sum channel output, the audio channel mapping is configured using the internal HTTP web interface or by using ANEMAN software or similar. The web interface can be accessed through GLM, or directly from the browser using the device name. For example, if the name is “9401A_61“, the web interface address is “http://9401a_61.local/advanced”.

In the web interface:

• Open the I/O router tab
• On the matrix view, inputs are shown on the rows and outputs on the columns
• Set up streams by selecting input-output pairs in the matrix
• Changes are automatically applied

The 9401A can also be used to route AoIP streams to other compatible devices. Usethe Session sources tab to create a new source. Refer to the Web interface function
reference for additional information on configuring a source. After the source is created, it can be routed from the I/O router tab as explained above.

Acoustic Calibration
GLM software supports automatic calibration and system alignment of the complete monitoring system. To acoustically calibrate your setup, attach the measurement microphone included with your SAM Reference Controller or GLM Kit onto a microphone stand so that the microphone points upwards, then place the microphone at the listening position with the microphone top positioned at the listener’s ear height.

Follow the steps in the GLM software to calibrate your entire system. The calibration process starts after you create a new group preset using ‘File’ | ‘New’ menu item. An existing group preset can be calibrated by selecting the ‘Group Preset’ | ‘Calibrate’ menu item. If you wish to disconnect the computer after calibration, save the GLM calibration onto the monitors, subwoofers and 9401A interfaces in your system. The settings can be stored using the GLM software menu item ‘Store’ | ‘Store the Current Group Settings’. Note that monitors and subwoofers have a switch that enables stored settings. This switch must be set to ‘ON’ for operating the system with the stored settings. After removing the GLM network cable and powering the 9401A and all monitors off and on, the stored settings are enabled. We strongly recommend using GLM software and keeping the GLM network connected to access the full flexibility of the monitoring system.

Returning to Factory Settings
GLM settings stored in a 9401A can beerased by keeping the power switch depressed for more than 10 seconds before releasing it again. This returns the 9401A to its factory settings. After this, GLM software should be used to reconfigure the 9401A.

Operating Environment
The 9401A is designed for indoor use only, and the permissible ambient room temperature is 15-35 degrees Celsius (59-95°F) with a relative humidity of 20% to 80% (noncondensing). If the 9401A has been stored or transported in a cool environment before entering a warm room, please wait between 60 minutes before unpacking it, as this will prevent harmful condensation. Sufficient cooling must be ensured to keep the 9401A within optimal operating temperatures. No minimum clearance for ventilation is needed around the interface.

Maintenance
There are no user serviceable parts inside the 9401A. Maintenance or repair must only be performed by Genelec certified service personnel.

Guarantee

Genelec guarantees the 9401A for two years against manufacturing faults or defects that alter performance. Refer to the reseller for full sales and guarantee terms.
