Emerson ANALOG connected to audio setup


What is the purpose of the two LEDs on the Emerson’s front panel?

The Emerson displays two electroluminescent diodes (LED) on its front panel. Both LEDs vary according to the use of the Emerson.

  • The LED is continuously switched off:
    The Emerson is switched off and will not be visible on the network. 

  • The LED flashes slowly:
    This phase generally lasts for about ten seconds after having switched the Emerson on until it obtains a valid IP address on the network.
    If the Ethernet RJ45 cable is not connected or if the network is not operational, the LED continues to blink indefinitely.

  • The LED blinks fast:
    An update of the internal firmware is running on the Emerson.

  • The LED is continuously switched on in red:
    The Emerson is under tension and its IP address is valid.
    The Emerson is ready to play music.


  • The LED is continuously switched off:
    No piece of music, nor any audio stream is currently read with the Emerson. The LED is in this state after a STOP command.

  • The LED blinks:
    The reading is currently on PAUSE on the Emerson.

  • The LED is continuously lit red:
    A piece of music or an audio stream is currently read. The LED is in this state after a PLAY command.

  • This scenario occurs when a firmware update has failed. It is necessary to start the update procedure from the Emerson Web page.


What is the meaning of the trailing number in the Emerson's name on the network?

As a UPnP / DLNA device, the Emerson announces itself on the local network using its friendly name.

For identification purpose, the last number of its IP address is automatically added at the end of its friendly name. This number cannot be changed by the user, even when the friendly name is changed.


To learn more about the how to change the name of the Emerson on the network, you can refer to its installation guide.


Why is the Emerson not visible on the network?

Your Emerson might not appear on your network for several causes.

Explore and validate the following points in order to identify the origin of the problem.

Power control

When it is on, LED A on the Emerson’s front panel must be continuously switched on or blink.

Should this not be the case, check the external power supply connections, ensuring that the main bloc is connected to an AC power outlet and that the electric plug on the Emerson’s back panel is fully inserted. Remove it and insert it again if required.


Network connection control

In case the Emerson cannot find a valid IP address on the network, LED A will slowly blink.

If this is the case, start by checking the state of the Ethernet RJ45 cable at the rear of the Emerson in order to ensure that it is not damaged. Should the cable be in good shape, unplug it and replug it until to hear a "click" ensuring that it is well in place.


If after several seconds the power LED still blinks, we recommend that you check the rest of your network installation.

Home networks can be configured in a multitude of different ways and can be the source of many faults. Connect a network specialist if necessary.

Once the previous checks have been performed and validated, your Emerson must be powered and LED A must be continuously switched on.

Should this not be the case, please contact your Wattson Audio retailer.


How to access the Emerson’s Web page?

As soon as it is connected to the network, the Emerson gets an unique IP address from your router. It is then possible to access the Emerson’s Update and Configuration Web page located as this IP address. This Web page is useful to update the firmware of the Emerson, as well as changing its friendly name on the network.

There are different ways to access this page:

From the iOS Wattson Music app

Once connected to your Emerson from the iOS Wattson Music app, select the "Remote" tab.

On this screen, you will find information to identify your Emerson on the network, such as its "IP Address".

You can then either directly open the link provided by the IP address, or copy this IP address in a Web browser’s address bar.

This done, you will access the page "Update and Configuration".

From Android

As for iOS, Android does not natively support the UPnP / DLNA protocol used by the Emerson. You will then have to use a third-party UPnP controller app (BubbleUPnP, mConnect Player,...) to access your Emerson and thus find its IP address on the network. Copy this IP address in a web browser’s address bar to access the page "Update and Configuration".

From Windows 10

As a "Media Renderer", your Emerson is displayed in the Windows network area as a "Media Device". The most straightforward way to access the "Update and Configuration" Web page is as follows:

  1. open the Windows Explorer,

  2. select "Network" in the left panel,

  3. in the "Media Devices" category, you should see your Emerson listed,

  4. double-click on your Emerson and wait for the Web page to open in your default browser.

From macOS

As for iOS and Android, the UPnP / DLNA protocol is not natively supported. You will then have to use a third-party UPnP controller application (Audirvana, JRiver, ...) to access your Emerson and thus find its IP address on the network. Copy this IP address in a Web browser’s address bar to access the page "Update and Configuration".



If you still cannot find the IP address of your Emerson on your local network by using one of the methods described above, you can try to get it from your router’s administration page. Almost all routers on the market have an administration page used for network configuration purpose and from which it is possible to get the list of all connected devices on the network.


As a reminder, we do not provide any technical support for third-party UPnP controller apps and applications, nor for the configuration of network devices such as routers, modems, etc.


What does mean the error message "Wrong file format" that can be displayed while updating the Emerson’s firmware?

The necessary firmware file for your Emerson’s update is a "binary" file ending with a ".bin" extension. The selection of any other file format will produce this error "Wrong file format".

In order to solve this problem, ensure that the file you have updated is indeed the expected binary file and that its name ends with the ".bin" extension.

If the update file still includes the ".zip" extension, it means that it has not yet been unzipped. Double-click on this file in order to unzip it and ensure that the resulting file name ends with ".bin" before starting the updated process.

If the update file ends with the extension ".bin", ensure that you are selecting the appropriate file when you click on "Selection of the .bin file".


Why is it not always possible to connect to the Emerson with AirPlay?

As long as you do not change the Emerson’s friendly name, you will have no problem connecting with AirPlay.


If you want to change the friendly name of your Emerson, you must absolutely use no special characters or emoticons in the new name. Apart from standard alphanumeric characters, only the space " ", the dash "-" and the underline "_" can be used.

Should you experiment troubles to connect with AirPlay, try to rename your Emerson from its Web page and to respect the rules above.


This limitation should be solved in a future Emerson firmware update.


Is the Emerson compatible with Roon?

Yes, the Emerson is certified Roon Ready.

This means we use the Roon streaming technology that gives you access to the highest levels of audio performance, without compromise, backed by a comprehensive and intuitive user interface, simple configuration and rock-solid daily reliability.


You will need to install the latest Emerson firmware to use your device with Roon.


Which control application may I use?

We strongly recommend the use of our iOS Wattson Music application. It has been optimized for the Emerson and offers an integral control of your device’s functionalities.


However, the Emerson respond to the UPnP AV /DLNA protocol and may be piloted by numerous applications compatible with this norm. We may namely recommend Audirvana for macOS and Windows, BubbleUPnP and mConnect Player for the Android devices.

Wattson Audio does not provide technical support with these third-party applications.
