Remote Control

Remote control battery

  1. Remove the battery cover on the rear of your remote control by pulling the small slot on the side of the remote body.
  2. Insert 2 x AAA size batteries into the spaces in the compartment. Take care to ensure the batteries are inserted in the right direction as shown inside.
  3. Replace the cover. If the remote is not to be used for an extended period of time it is recommended that the batteries are removed. 

Caution: Replace batteries only with the same or equivalent type. Danger of explosion if the batteries are incorrectly replaced.

Basic Controls

  • Press and release On/Standby to switch your audio system on or off.
  • Pressing the Mode button gives you access to each of the operating modes in turn. Alternatively, apply a long press on the Mode button and then use the Menu Left or Menu Right buttons (on the remote control) or turn the Tuning/Select control (on the unit) clockwise or anti-clockwise to highlight the desired menu item then press Select to select that item.
  • Pressing the Menu button will access the menu system.
  • Many operations require the user to make a selection from the menu. This is done using the Menu Up or Menu Down buttons (on the remote control) or the Tuning/Select control (on the unit). Press Select (or the control dial) to select that item.
  • If an error is made when navigating the menus, it is generally possible to go back to a higher level menu by pressing the Menu or the Back button.
  • The Info button allows the display of information relating to the radio station or music file being played.

Setup & Configuration

Your audio system may be configured using either the display and buttons on the audio system, or by using the UNDOK app.

  1. Place your audio system on a flat surface and plug the mains lead into the mains socket located at the rear of the audio system ensuring that the plug is pushed fully into the socket.
  2. If you wish to use a wired network connection, plug the Ethernet cable into the RJ-45 socket at the rear of the audio system.
  3. Plug the other end of the mains lead into a wall socket and switch on the socket.

IMPORTANT: The mains plug is used as the means of connecting the audio system to the mains supply. The mains socket and any multi-way mains block used for the audio system must remain accessible during normal use. In order to disconnect the audio system from the mains, the mains plug should be removed from the mains socket outlet completely.

  1. When you apply power, the display on the audio system will light up and show a start up screen for a few seconds.
  2. If this is the first time that you use your audio system (or after a Factory Reset) the display will show the language menu.
  3. By default your audio system will display all menus and messages in English. Press Menu Up or Down to highlight the desired language. Press Select to enter the selection. ‘Setup wizard’ and ‘YES’ will be highlighted on the screen.
  4. If you would like to setup your audio system using the audio system’s controls instead of the UNDOK app then press Select to select ‘YES’ and to begin setting up your audio system.

Clock and time settings

When setting the system up for the first time, it will prompt you for your preference for the clock. We recommend ‘update from network’ for the clock update method. You may also choose FM/DAB or manual time adjustment.

Alarms & Snooze

You can use the menu to set alarms that use any audio source as the wake method. When the alarm is sounding, some functions are disabled. The select button becomes a snooze button which will start the snooze timer cycle. When in snooze, the snooze time is displayed on the screen.

To cancel snooze or the alarm, press the on/standby button.

Sleep Timer

When playing any audio source, you may choose to start the sleep timer. This will play the audio for a defined time, then gradually fade out.

Audio Equaliser

The System menu contains settings for the equaliser. This contains several standard presets and a ‘normal’ setting which is the factory default for the unit tuned by Roberts acoustic engineers. Choose different acoustic settings according to your taste, or use the ‘My EQ’ setting to program your own balance of sound emphasis.

Connecting to your computer network (setup wizard)

Before you can use your Stream 67 audio system to listen to Internet radio or to music streamed from your computer, it must first be connected to your WiFi or ethernet network.

After setting the Daylight Savings options, the display will show the ‘Keep network connected?’ option. You should choose ‘Yes’ if you wish to keep the audio system connected to the network when it is in Standby mode. This will allow remote control software to switch on your audio system when needed.

If you choose ‘No’ then your audio system will shut down its connection when it is in Standby, DAB, FM, Bluetooth, CD or Aux-in modes. This minimises power consumption but it does mean that you will need to switch the audio system on manually in order to use either Spotify Connect e.g.

Setup Wizard

Press Menu Up or Down to highlight the required region (for the UK choose ‘Europe’), and then press Select to make the selection. Do this even if you are planning to use the wired Ethernet connection. Your audio system will then scan for available WiFi networks.

The audio system will enter the Network Settings Wizard and will display ‘Scanning…’.

To use the Ethernet connection to your router (with automatic configuration), press Menu Up or Down to point to the ‘[Wired]’ menu item. Press Select and the audio system will attempt to connect.

Connecting to a wireless network

When the SSID for the wireless network you wish to connect to is highlighted on the screen, press Select. If WiFi Protected Setup (WPS) was indicated, you will see an additional menu at this point.

For WPS systems: Choose one of the WPS menu options as required for your router (WPS may be via push button, or using an identification number).

  • ‘Push Button’ – the display prompts you to press the WPS button on your router and then Select on the audio system. The two devices should then connect with the encryption key sent automatically to the audio system.
  • ‘PIN’ – the display shows an identification number which you must enter into your router using a web browser (refer to your router’s user documentation). You should then press Select on the audio system. The two devices should then connect with the encryption key sent automatically to the audio system.
  • ‘Skip WPS’ – if you wish to enter the WiFi password yourself (or if it was previously entered).

If the screen displays ‘Key:’, you will need to enter the correct password key into the audio system to allow it to communicate with your wireless network. If you do not have the WEP or WPA key, then you should obtain it from the person who set up your network.

From time to time, you may find that you need to connect to different computer networks. The Network Settings menu allows you to change your audio system’s network settings, scan for an alternative wireless network, or, manually configure the network parameters.

Configuration using ‘UNDOK’

You can download the UNDOK app from Google Play or iOS App Store. This app allows you to configure many things on the Stream67L in a convenient way on your phone or tablet.

With the UNDOK app, you can conveniently do the following from your smartphone:

  • Control Internet radio stations / manage presets
  • Manage podcasts
  • Display WiFi configuration / details
  • Set the language
  • Configure the sleep timer
  • Set the time/date
  • Alter equaliser settings
  • Factory reset
  • Alter audio quality settings

Note: To enable Amazon music, you MUST log in to your account via the UNDOK app. It is recommended to use the app for Deezer.

Listening to Radio

  • Press select (push the tuning dial).
  • The system will same the station in the slot for future reference.

Recall a Preset

To quickly recall a saved station, short press the preset button, then choose a slot. The system will recall the station.

Music Player (USB)

Important: Your audio system is only designed to work with USB flash memory devices. It is not intended to be connected to hard disk drives or any other type of USB device.

Audio formats supported are MP3 and WMA. USB playback does not support files encoded using WMA Lossless, WMA Voice, WMA 10 Professional, nor files of any format which have DRM protection.

Searching and playback will be more responsive if the number of files in any one folder is limited (we suggest not more than 250).

Playing files from USB memory devices

  1. Carefully insert the USB memory device into the USB socket on the rear of your audio system. Press On/Standby to switch the unit on. The audio system may detect that the memory has been connected, in which case it will ask whether you wish to open the folder view of the memory contents. Press Select to select ‘Yes’ and skip to step 4 below.
  2. To select USB playback mode press Mode as needed until the Music Player mode is selected. If needed press Menu.
  3. Press Menu Up or Down until ‘USB playback’ is highlighted on the display and press Select. The audio system will now list the content stored on the USB memory device. If there are many files or folders this may take a few seconds.
  4. Press Menu Up or Down to highlight the required folder and press Select to enter the current folder. The list of tracks in the current folder will be displayed. Alternatively, if you have nested folders (such as album folders within an artist folder) then you will simply step to the next folder level.
  5. Press Menu Up or Down to select the track and press Select to begin playing from the highlighted track. All files in the current folder will then be played in turn.


Your audio system can be configured to hold a queue of up to 500 tracks in a playlist menu. The tracks or albums for the playlist can be selected from your UPnP server and from a USB memory device.

Adding a single track, entire album or folder to your playlist:

  1. When selecting (or when playing) a track using a UPnP server or a USB memory device apply a long press on Select and the display will show ‘Added to My playlist’.
  2. The track will be added to the playlist for playback later.
  3. When using a UPnP server or a USB memory device highlight the chosen album, artist or folder and apply a long press on Select. The display will show ‘Added to My playlist’.
  4. Each of the tracks within the album, artist or folder selection will be added to the playlist individually. This allows any unwanted tracks to be removed from the playlist if needed (see below).

You can view your playlist end edit it by entering the menu and choosing the ‘My Playlist’ option.

Network Audio

Spotify Connect

The audio system will appear as a Spotify connect device from Spotify players connected to your local network. E.g. when using spotify on your phone, look for the ‘speakers’ icon within the Spotify app and choose the Stream 67L to play audio. Spotify is an extremely convenient way to play audio as the Stream 67L will stream audio directly from the Internet without draining your phone’s battery or requiring you to keep the app open or active.

Prune Servers

Your unit stores details of UPnP servers that it has seen via its network connection in its internal memory. The prune servers function allows only active UPnP servers on the currently connected network to be shown when selecting ‘Shared Media’ from the Music Player menu.

Press Menu. Choose ‘Prune servers’. To remove servers that are no longer required choose ‘YES’. If you do not wish to prune servers choose ‘NO’.

Keep network connected

Your audio system has the option to shut down its WiFi or Ethernet connection when it is in Standby. This minimises power consumption but it does mean that you will need to switch the audio system on manually in order to use either Spotify Connect, the ‘Play to / Cast to Device’ function or any remote control software such as the UNDOK app. Choosing to keep the network connected will use slightly more power, but ensure the device is always available on your network to play audio on demand.


Bluetooth allows an easy way to connect and play smart audio devices through your Stream 67L. Choose the Bluetooth mode and the device will attempt to connect to the last connected Bluetooth audio device. If it is not able to automatically connect, it will be available to connect.

Connect to Bluetooth

  1. Ensure that the Stream 67L displays ‘Looking for Device’ or similar message.
  2. Look in the Bluetooth connections list on your smart device for the Stream 67L
  3. Select it to connect.
  4. The device should pair and audio will be available.

In the menus you also have the option to cause the system to disconnect from a Bluetooth device and clear pairings. This will cause the system to forget all devices previously paired. Choosing this option will mean you will need to re-pair a device to play audio.

CD Player

IMPORTANT: Only use standard (full) size CDs in the Stream 67L.

The system supports standard CD-DA (digital audio) discs as well as discs containing WMA or MP3 files with a sample rate of the standard 44.1KHz.
