  • My Go+Play Wireless uses up all battery power within about two weeks. Can it be switched off completely, resulting in no power drain?
    The Go+Play Wireless must be in Standby to be able to switch On when receiving a signal. This function uses a small amount of power, and cannot be switched off. Remove batteries when not in use for more than 2 weeks to prevent power draining.
  • My hair or cap activates the touch system on my Reflect Response. How can I avoid this?
    A certain degree of sensitivity is necessary to make the response system function. In some cases, hair or a cap touching the sensor plates can activate the system, even if you do not want it. The solution is to lock the sensor system. Put your finger on the left sensor plate, and hold it there for more than 4 seconds. Now the sensors are locked, and the problem is solved. Unlocking is done the same way.

  • My headphones told me heart rate disconnected. How do I reconnect it?

  • My JBL GO goes into standby when I play quietly. Why is that, and can something be done to change this?
    With some phones, such as iPhones and some Android models, volume is synchronized while Bluetooth is used, and levels below volume setting 6 (tested with iPhone 6 and iPhone 5s) and volume setting 5 on most Android devices will cause the GO to enter standby after some minutes. If you want to play softer while still using your iPhone as a source, please change to cabled connection from the headphone output to the AUX input of GO. This will make it possible for you to set the GO's volume at its minimum step, and then control total level on the telephone. Of course, if source level from the telephone is set extremely low, the GO will go into standby again, because GO needs a certain level to keep playing. Alternatively, use a phone which does not synchronize volume as source. Many Android phones do not synchronize volume, so by using such a phone, you can adjust GO to its lowest level, adjusting total level independently, even via Bluetooth. This will usually result in music volume at the desired level.

  • My JBL SB250 should turn on automatically when receiving an audio signal at either input, according to the owner's manual. However, this does not happen.
    We are sorry about this problem. EuP regulations require that electronics go into full off after some time. Unfortunately, this means that the soundbar cannot be woken up again after half an hour. It is necessary to use the ON/OFF switch.

  • My No. 40 is not working, there is a WAITING FOR VIDEO BOX message on the front of the No. 40 Audio Processor, what do you recommend?
    First try turning power to the No. 40 OFF, disconnect then reconnect the existing comms cable between the No. 40 Audio and Video processors, and power the No. 40 ON. If this does not help try a different comms cable, this is a straight through 4 conductor cable with a 4 pin connector on each end. If replacing this cable does not help contact one of our authorized service centers for repair assistance – their contact information is under the SUPPORT tab on the Mark Levinson website.
  • My OMNI+ speaker will not connect to my Wi-Fi, is it defective?

  • My OMNI 10+, 20+ or 50+ speakers are connected to my network, but I cannot see them in the HK Controller app
    Dual band routers that have 2.4 and 5 GHz connection bands. If devices connect on different bands, they cannot see one another. Please make sure your phone and speakers are both connected to 2.4 GHz or 5 GHz and that there is no AP isolation activated between them.
  • My OMNI 50+ does not react when I am trying to pair it via Bluetooth?
    One explanation can be that your OMNI 50+ is part of a 5.1 system with your Omni Bar, which will make the surround OMNI 50+ left and right rear speakers act as "secondary", and Bluetooth connection is not possible to secondary speakers. To use the OMNI 50+ as a portable speaker again, simply perform a reset of the speaker by pressing the reset button for 5 seconds. Please note that after resetting your OMNI 50+, it is no longer part of the 5.1 wireless system.

  • My receiver does not show "DTS HD Master Audio" in the display, even though the Blu-ray disc should have this format. Instead, it just shows "DTS".
    With some Blu-ray discs, you have to go to the Settings Menu of your Blu-ray player and select "Bitstream" or "Bitstream Native". This will carry the DTS HD Master signal to be decoded in the AVR, and the AVR front panel should show the correct text.
  • My receiver makes a clicking sound when I adjust the volume. Is this normal?
    Yes, this is a normal characteristic of this system.
  • My remote control is not working. I have a credit card-sized remote with disc type battery. Do I need to replace the remote control?
    It is usually not necessary to replace an unresponsive remote control. First, check to see if there is a small plastic tab extending out of the base of the remote control. This is a protective sleeve installed on new remote controls to prevent the battery from draining. Pull this tab to remove the plastic sleeve. The sleeve must be removed before the remote will operate. If the sleeve was removed or not present and the remote control is not working then a new battery should be installed before replacing the remote control. There is a small slide out drawer that houses the battery. The battery type will be either CR2025 or CR2032 for remotes of this size. Replacement batteries are commonly available from most electronic and convenience stores that sell small batteries. Check the number on the original battery and replace it with a battery that uses the same number. These steps will typically solve the problem.
  • My SB20 is in demo mode, how can i get it back to normal?

To stop the demo mode, either perform a full reset by holding down volume+ and surround button for 5 seconds or when power is on, press volume- and surround button again for 5 seconds.
  • My smart phone falls off of the Smartbase charging arm.
    This can be caused by dirt and dust accumulating on the charging arm, which can reduce the effectiveness of the adhesive. Clean the surface of the charging arm with a wet cloth or alcohol wipes. Do not use paper towels as these can leave paper debris.
  • My speakers can handle more power than my amplifier is putting out, yet I keep blowing them. Why is this happening?
    There are two ways to blow speakers. The first is the one we all know and understand. If you pump 500 watts into a speaker that is only rated at 100 watts, kaboom, it blows up. As a result, very few of us do this. So then why are all of these poor, helpless speakers blowing up? Because of the second reason, under-powering. It's really a misleading term, but let's try to explain. First let's take it to the maximum. Example: You have a 1000 watt speaker and a 100 watt amplifier. The way you like to listen to music requires 300 watts. Typically, you will ask your amp to put out that 300 watts that you want to hear. The amp will do it, but it will clip and distort. Unfortunately, the human ear can't hear distortion until it reaches almost 10%. By that time it's usually too late. The speaker keeps trying to reproduce this distortion that it's not capable or reproducing and eventually it blows (usually the tweeter fails first). If you are blowing speakers with an amp that has a power rating lower than your speakers, you are pushing your amp too far, causing it to clip, and blowing speakers. If you are pushing your system too hard, it is suggested that you realize your systems limitations or recommend that you get a more powerful amplifier. Please realize, if you only buy speakers that will handle more power and not a more powerful amplifier, you won't solve the problem. The speakers will still blow, because it is distortion that is blowing them, not too much power.
