What is the average time before the speaker enters its power saving mode?

After about 30 minutes of no sound (silence) the speaker enters its power saving mode.

How do I turn the speaker on/off?

Use the on/off button on the top left side of the remote.

What do the LED mode colours mean?

The LED colours indicate the mode that is selected:
Blue = Bluetooth
Red = USB
Green = AUX
Orange = Optical
White = HDMI-ARC

What lighting colour modes can you set?

There are 6 pre-defined light modes that you can set with the lights button (marked with the light bulb) on the remote:
1. Rainbow
2. Cycle
3. StatRing
4. Ambient
5. Neon
6. Static
7. Off 

My speaker (with smart power management) won't resume playing?

Your speaker will go into Standby mode if it doesn’t detect audio input after a specific amount of time.

This speaker uses a fixed threshold input level to enable the smart power management feature. This means if you greatly lower the volume your speaker might interpret this as silence and go into Standby mode. 

To avoid this from happening, turn up the volume as high as it can go without distortion setting in, and use the volume controls on your speaker to determine how loud (or soft) you want your audio.

Please note that some computers won't let attached devices resume from standby-mode due to configuration, the speaker then has to be switched on manually.

My speaker (with smart power management) stops working after some time, what is happening?

After a period of no sound, your speaker has entered a power saving mode in order to preserve energy. When you play music again, the speaker will automatically resume playing as usual.

How long does it take for the speaker to resume playback once it's in its power saving mode?

When resuming the audio playback it takes about 1-2 seconds before the speaker is active again.

Please note that some computers won't let attached devices resume from standby-mode due to configuration, the speaker then has to be switched on manually.

How can I make sure my speaker does not enter its power saving mode unintentionally?

Increase the volume of the source (computer, laptop, tablet, smartphone, etc) and decrease the volume of the speaker to the desired volume.

What is the Eco design directive about? (Also called ErP II)

ErP is a legislation from the EU, setting eco requirements to Energy Related Products.
These requirements are intended to reduce (standby) power consumption and in general reduce energy losses.

Solving problems

I have a Dell computer and am having issues with the computer audio. What can I do?

If you are experiencing audio issues on your Dell computer, make sure to install the latest audio drivers for your computer from the Dell website at https://www.dell.com/support/home/en-us?app=drivers

If this does not solve your problem, contact the Dell support or your system administrator. 

The remote is not reacting (correctly).

First check the battery. If the battery starts to run out, the working distance of the remote decreases and the speaker will often no longer respond consistently. Try a new battery, and check if the issue persists.

If a new battery doesn't fix the issue, contact our support team for further advice.

One of the speakers is not working. What can I do?

We recommend to test the speakers first, by switching the left/right output of the subwoofer.

Furthermore, it is advised to check if the problem is related to the subwoofer output or to the speaker itself.

Subwoofer is not working.

  • Make sure the subwoofer volume knob is open.
  • Check cable connections of subwoofer.
  • Check connection of speaker to soundcard  (colors of connectors must match colors connectors PC-side)
