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.

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

After about 60 minutes of no sound (silence) the speaker enters its power saving mode.

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 lost/broken the remote. How do I receive a new remote?

If you have lost or broken the remote, contact our support team via the "Contact us: Ask a question option" on the product page. Include as many details as possible such as purchase date and address details. As the more info you fill in, the quicker the team will be able to process your request and the sooner you’ll hear from our team.

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.

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)
