FAQ

The Control Hub is reacting to remote control commands, but the remote control is behaving strangely

• Make sure the remote control protection film is removed.
• Make sure the batteries in the remote control are fresh.
• Strange behavior may happen if the remote controls touch buttons are improperly calibrated. Make sure the remote control is properly assembled after batteries installed. The plastic alignment tab of the housing should be fit into the alignment hole of the circuit board. The acrylic glass faceplate should be flush with the plastic housing. Lay the remote control on a table and don't touch it for 20 sek. This lets the touch buttons recalibrate.
• Try using the remote control closer to the Control Hub. If this helps the distance might be too long.
• If the system has been unused for a longer time you will need to press and hold the button for a longer time (at lease 2 sek). This is due to the remote controls built in low power sleep mode used to extend its battery life.

The Control Hub status LED is flashing red

This is due to a short circuit somewhere in the speaker chain.

• Look at all your speaker terminals, both on Control Hub and speakers. Make sure that both poles are not touching each other. Also make sure that the metal housing of Flow series speakers or RCA connectors of Control Hub is not touching any speaker cable.
• Make sure the speakers are connected according to the user guide.
• Turn the system off using the remote control and disconnect all speaker cables from the Control Hub. Turn the system on using the remote control. If the Control Hub is still flashing red the short circuit is inside the box. This is highly unlikely and in this case you may contact your Opalum dealer.
• Try connect only one speaker at a time. If only one of the speakers produces this error then a short circuit may be inside that speaker. Please contact your Opalum dealer.

The Control Hub turns itself off after a while

To save power the Opalum system will automatically go into sleep mode and later on shut itself off. Sleep mode is entered after 20 min without any input signal on the selected source. This is indicated by a slowly fading Control Hub status LED.

In sleep mode the power to the speakers is turned off. The system will wake up from sleep mode if a button on the remote is pressed or audio is played on the selected source. After two hours in sleep mode the system will shut itself down. The system now needs to be started by using the remote control. If the volume is set at full by this two hour shut down will take place.

This mode is intended for installations where the Opalum remote is not used since the volume is controlled by the source. Sleep mode will still be active.

The Control Hub is on but there is no sound from the speakers

• At first, please make sure that the volume setting of the Opalum system is not too low. Also make sure the volume of the source is raised. If you are using wireless streaming (optional) there may also be a volume setting in the control point application/player you are using.
• Volume problem may occur if the remote control is behaving strangely. Please see topic “The Control Hub is reacting to remote control commands, but the remote control is behaving strangely”.
• Try using the analog RCA input with a known good source if you are experiencing this problem when using digital sources.
• For digital sources: Make sure the digital S/PDIF format is PCM at 44.1 or 48kHz sample rate. Surround sound formats such as DTS, Dolby Digital etc. are not supported.
• If this problem occurs when using the coaxial digital input, try using an optical input if your source also has an optical output (and vice versa).
