If you want to connect a different subwoofer, you need the Subwoofer Wireless Receiver. More information can be found here → Can I add a wireless connection to my subwoofer?
Remote Control
The remote control operates your ULTIMA 25 ACTIVE via infrared. If it stops working, please contact our customer service.
Which side should the active speaker of the ULTIMA 25 ACTIVE be on?
You can place the active speaker either to the left or right of your listening position. The important thing is to correctly set the speaker position in the menu afterward.
Go to the Menu ► Speakers ► Position ► Left / Right
There you specify whether the active speaker is on the left or right. The passive speaker automatically takes the opposite position. This ensures that the stereo channels are reproduced correctly.
How do I delete settings or perform a reset?
With the ULTIMA 25 ACTIVE, you can perform a factory reset, which restores all settings to their default values. Afterward, you'll need to set up the system again. Alternatively, you can reset only specific settings, such as the Bluetooth® pairing list, the connections to paired speakers (rear speakers/subwoofer), or the sound and radio settings.
- If you want to delete the Bluetooth® list, you have the following options:
- Press and hold the Bluetooth® button (Bluetooth® symbol) on the control panel or the Bluetooth® button (BT) on the remote control for 8 seconds.
- Delete the Bluetooth® list via the menu: Menu path: System ► Reset ► Bluetooth.
- If you want to remove/cancel the connection to the paired speakers (rears/subwoofer), use this menu path: System ► Reset ► Rears/Subw.
The wireless connection/pairing of the selected speaker will then be deleted. - If you want to delete the sound settings, use this menu path: System ► Reset ► Sound
- If you want to delete the radio settings, use this menu path: System ► Reset ► Radio
- Reset to factory settings
NOTE: All user settings and data will be deleted and reset to factory defaults. You will need to set everything up again afterward.
To reset the ULTIMA 25 ACTIVE to factory settings and use this menu path: System ► Reset ► Factory Settings.
My ULTIMA 25 ACTIVE automatically switches to the "Optical" source even though no signal is currently input there. What causes this?
Possible cause: Auto-On for the Optical input is active. Auto-On also reacts to possible test signals.
Solution: Turn off the "Auto On" function for Optical.
Menu path: System ► Advanced ► AutoSwitch ► TV HDMI / Bluetooth / AUX / USB / Optical ► On / Off.
When switching sources during playback, e.g. from Spotify to YouTube, playback suddenly mutes. What can I do?
Solution: Press pause briefly, then press play again.
