      Step 1: Power ON both dongles by flipping their respective power switches to "ON" position.

      Please make sure that they are charged. You may refer to THIS ARTICLE if you're not sure how.



      Step 2: Allow the two dongles to reconnect with each other.

        • Oasis Plus headset
      • Option B - RCA (RED / WHITE)
        • Please note that ONLY the ones that are labeled "AUDIO OUT" can be used; the other ones won't work.

  • How to Use Both Dongles Together as a Tandem

    The two dongles can be used in a tandem as a Bluetooth range "extender" for 2 other already-paired devices.

    Step 1: Power on the RX dongle

    Please ONLY power on the RX dongle for now; leave the TX dongle OFF.

    Step 2: Get the RX dongle into Bluetooth Pairing Mode, and pair it with the device that's "transmitting" the audio.

    This can be a Mobile Device or a Bluetooth TV... or simply another Bluetooth Transmitter.


    Step 3: Get the TX dongle in to Bluetooth Pairing Mode, and pair it with the device that's "receiving" the audio.

    This is likely a Bluetooth headphone/speaker, or another Bluetooth Receiver. Please make sure you only get to this step AFTER step 2 has been completed.


    Step 4: Connect the two dongles to each other.

    Take the 3.5mm AUX connector that we provided, plug one end into the 3.5mm AUX port on the TX dongle, and the other end into the 3.5mm AUX port on the RX dongle.

     


    And you should be good to go! If you have any question, please email us at support@avantree.com!

  • Lock Dongles No Sound / Not Working

    If you have something plugged into the HDMI port on your TV, please check and see if the port you're using is a HDMI ARC port. For most TVs, when something is plugged into the ARC port, its other audio output ports will automatically be muted. Please switch to another HDMI port.

    IF you have a sound bar or AVR that's using ARC, please consider switching to Digital Optical instead.

    All set up but can't hear anything through your headphones?

    Please follow the troubleshooting steps below:

    Step 1: Check the LED indicators on each dongle, the TX dongle should be DOUBLE-FLASHING WHITE and the RX dongle should be DOUBLE-FLASHING BLUE. Are they doing that?

    • If YES - Awesome! Proceed to Step 2!
    • If NO - The two dongles have not connected to each other, please connect them. Refer to THIS ARTICLE if you're not sure how.

    Step 2: Turn off one of the dongles. Did the dongle that's still on start to SINGLE-FLASH instead of DOUBLE-FLASH?

    • If YES - Nice! That means the two dongles have properly connected to each other and not something else. Please proceed to Step 3!
    • If NO - Looks like one of your dongles has paired with something else... Please factory reset both of them. Refer to THIS ARTICLE if you're not sure how to reset.

    Step 3: Has the transmitter been properly connected to your Device? Double check with the articles below.


    Step 4: IF your answers have all been YES so far yet there's no sound, it's time to send us an email.

    Please email us at support@avantree.com with a detailed description to your issue, we'll have someone assist you right away.

All Questions

  • Set Up Procedure
    • Part 3. Adjust TV Audio Settings (Samsung, LG, Sony, VIZIO, Panasonic...)

      By now, your transmitter should be connected to your TV / Audio source (Part 1).

      Your headphones and transmitter are paired and connected (Part 2).

       

      This Step 3 is to make sure the compatible audio signal is received by the transmitter.

       

      If you are using RCA or AUX connection, you need to adjust TV Sound OUT to 'Headset' or "External speaker"

       

      Image 1- 3.5mm AUX jack

       

      Image 2- TV RCA audio out(Red/White ports labeled "AUDIO OUT ")

           

       

      Image 3- TV sound out settings with "Headset" or "External speaker" selected

      or

       

      If you are using an Optical or HDMI ARC connetion, you need to:

       

      1. Set TV Sound OUT to "Optical / Digital Audio Out/HDMI ARC."

      2. Set Audio Input & Output format to PCM/Stereo (except for Avantree Orbit).

       

      Image 4- TV digital audio out port

      Image 5- TV sound settings - optical out

      Image 6- TV sound settings - HDMI ARC Out

       

       Image 7- Set TV audio format to PCM

       

      Please click into your TV brand below and follow the instruction Step-by-step.

       

      * If your TV brand is not listed below, you can do the following

      1. check TV manual or google its manual online and find its Audio output port options

      2. email support@avantree.com with the picture of your TV back panel ports so we can help. 

       

      Note 3.1 If you are using smart TV's HDMI ARC port, and your Sound output option HDMI ARC / Optical is ONE option, then your optical output will not work with HDMI ARC plugged in.

      Fix - use other HDMI port, not the HDMI ARC. 

       

      Note 3.2 If your TV is very OLD and you use Roku, Fire Stick etc. for Netflix, Amazon Prime movies, TV optical port might not be compatible with latest movie audio format and hence no sound for those. (very rare)

       

      Other General Troubleshooting Tips if No Sound after the following set up

       

      RCA / AUX - Plug in a wired headphone to test the sound output. If you cannot hear any sound, then either you are using the wrong port or TV Sound out set wrong. 

       

      Optical

      1) OPT is lit up SOLID? 

      2) Optical port & optical cable has red light inside?

  • Basic & Advanced Functions
    • How to Use Avantree TV Headphones / Transmitters with AV Receiver / Amplifier (Denon, Yamaha, Sony, Pioneer...)

      Here are a few typical set ups for your reference:

      Reference Connection 1  Use the AVR's Phones Output

       

      AV Receiver Headphone port <- 6.35mm-3.5mm adapter + 3.5mm/AUX cable -> [Avantree Transmitter] AUX in from TV port ...... Headphones 

      Pros: 

      1. Easy to set up

      2. No need to adjust the TV's audio format

      3. Listen to all audio through the AV receiver / Sound bar, not just the TV program

      Cons: 

      Mutes the AVR speakers

       

      Reference Connection 2 Use Optical Cable to connect the TV and AVR (Passthrough Function of Avantree Transmitter)

       

      TV optical / digital out <- optical cable -> [Avantree Transmitter] Optical in from TV (Black) | Optical out to speaker port (Gray) <- optical cable -> Soundbar / AV receiver optical in 

       

       

       

      Pros: 

      1. Both the speakers and wireless headphones will have sound

      2. Supports audio from all TV programs

      Cons: 

      1. Not all Avantree transmitters can do this; the ones that have this feature so far: Oasis Plus , HT5009, HT5006, Orbit , Opera , Medley Clear, Duet, & Quartet

      2. Need to set the Audio format on the TV to PCM except when using with the Orbit. As a result, you can't get surround sound through the AVR speaker.

      Reference Connection 3 Find an audio output on the AVR which can work with your soundbar at the same time such as the Zone 2 RCA output port (analog audio out) or the Zone 2 HDMI output (digital audio out).
      In order to ensure that the Zone 2 port works, please check the manual of the AVR for how to set up Zone 2 first.




      For RCA output port(Analog audio out port), please make sure its output power fits our transmitters' AUX input requirements:

      1. Max input level: 2000 Vrms 

       

      2. Input impedance < 64Ω

      If you're not sure, please check with your AVR's manufacturer, or you can try to plug a pair of wired headphones into the RCA port. If you can get sound through the wired headphones as normal, then the RCA port will work with our transmitter. 

       

      For Zone 2 HDMI output (digital audio out), you will need an additional HDMI converter to connect with the Zone 2 HDMI port.  https://avantree.com/hdmi-audio-extractor-converter-hax04

       

      Pros: 

      Keep Surround Sound 7.1 / 5.1 to your speakers with the Avantree Transmitter and TV headphones working at the same time 

      Cons: 

      May need to get an extra HDMI Audio Extractor 

      Not every AVR has these ports in the back

      If none of the above reference designs work for you, or you have other suggestions, we love to hear from you. Please email to support@avantree.com

    • How to Connect to a TV / AV Receiver, etc.

      Television, AV Receiver, Non-Bluetooth Laptop/Computer

      • Connecting to a TV

        Step 1: Power ON both dongles by flipping their respective power switches to "ON" position.

        Please make sure that they are charged. You may refer to THIS ARTICLE if you're not sure how.



        Step 2: Allow the two dongles to reconnect with each other.

        Just keep them close to each other and give them a few seconds. Once connected, the LED indicator on the TX dongle will DOUBLE-FLASH WHITE while the indicator on the RX dongle DOUBLE-FLASHES BLUE.


        Step 3: Connect a Wired Headphone / Speaker to the RX dongle.

        Plug the Headphone / Speaker into the 3.5mm (AUX) port on the RX dongle.


        Step 4: Connect the TX dongle to your TV.

        The Lock supports Auxiliary (3.5mm,) and RCA (RED/WHITE.) Please check and see which one your TV supports; any ONE of the two will work.

        • Option A - Auxiliary (3.5mm)
          • Take the 3.5mm Auxiliary Cable that we provided in the box, and plug one end of it into the "HEADSET" or "3.5mm AUDIO OUT" port on the back of your TV.
          • Oasis Plus tv aux
          • Plug the other end of the cable into the AUX port on your TX dongle.
          • Go to your TV's SOUND settings, make sure that the AUDIO OUTPUT has been set to "HEADSET." Some TVs automatically complete this step for you, some don't.
          • Oasis Plus headset
        • Option B - RCA (RED / WHITE)
          • Please note that ONLY the ones that are labeled "AUDIO OUT" can be used; the other ones won't work.
          • Plug the RED/WHITE end of the RCA-AUX Converter Cable into the RCA AUDIO OUT port on the back of your TV.
          • Oasis Plus rca
          • Take the 3.5mm Auxiliary Cable, and plug it into the BLACK end of the RCA-AUX Converter Cable.
          • Plug the other end of the 3.5mm Auxiliary Cable into the AUX port on the back of your TX dongle.
          • Go to your TV's SOUND settings, make sure that the AUDIO OUTPUT has been set to "EXTERNAL SPEAKER." Some TVs automatically complete this step for you, some don't.

    • How to Use Both Dongles Together as a Tandem

      The two dongles can be used in a tandem as a Bluetooth range "extender" for 2 other already-paired devices.

      Step 1: Power on the RX dongle

      Please ONLY power on the RX dongle for now; leave the TX dongle OFF.

      Step 2: Get the RX dongle into Bluetooth Pairing Mode, and pair it with the device that's "transmitting" the audio.

      This can be a Mobile Device or a Bluetooth TV... or simply another Bluetooth Transmitter.


      Step 3: Get the TX dongle in to Bluetooth Pairing Mode, and pair it with the device that's "receiving" the audio.

      This is likely a Bluetooth headphone/speaker, or another Bluetooth Receiver. Please make sure you only get to this step AFTER step 2 has been completed.


      Step 4: Connect the two dongles to each other.

      Take the 3.5mm AUX connector that we provided, plug one end into the 3.5mm AUX port on the TX dongle, and the other end into the 3.5mm AUX port on the RX dongle.

  • Troubleshooting
    • Audio Cuts Out Intermittently, Choppy, Unstable Connections,Short Range , How to fix?

      If you're experiencing intermittent Audio Cuts, please try to resolve the issues with the methods below:

      Method 1: Made Sure your Bluetooth headphone / speaker is NOT Multi-Linked

      Very often, the intermittent audio cuts out issue is due to the Bluetooth headphone / Speakers are also connected with other devices, e.g. your Cellphone, PC. Please make sure you turn the Bluetooth off on those devices. 

      Method 2: Clear Pairing History of BOTH devices and pair them again.( Clear Pairing History is NOT turn on/off.)

      • Clear Pairing History / Factory Reset the Headphones / Speakers. (Find the instruction under 'Basic & Advanced Features' under each Avantree product Guide. For Non-Avantree items, please google "Product brand model Clear Pairing History")
      • Clear Pairing History / Factory Reset the Adapter. (same as above)
      • Pair them up again. 

      Method 3: Clear away any potential Wireless Interference Devices.

      Other wireless devices in the vicinity of the transmitter may negatively affect the range. This "source of interference" can be a WiFi router, a TV box, or even just another Bluetooth device.

      To solve this issue, simply move either the transmitter or the source of interference away; that ought to clear the problem.

      Method 4: Check the Operation range of the other Bluetooth device.

      Certain Bluetooth devices have much shorter range; this "feature" is especially obvious on smaller Bluetooth devices like True Wireless Earbuds.

      If this is the case, the only real solution is to simply go with another Bluetooth device - one that has a better range.

      Method 5: Avoid Physical Objects.

      Walls, solid materials, or even human bodies can all become "obstacles" that negatively affect the Bluetooth device's range.

      Try clearing the space between your Bluetooth devices, and see if that helps.

      If the above is not helpful, please fill the form - Disconnects intermittently/Unstable Connections so we can get in touch and help you to solve the problem.

    • Accidentally Connected to my Neighbor's Speaker, What to Do?

      Step 1: Factory Reset & Turn OFF.

      You want to Factory Reset the Transmitter Adapter AND turn it off right after it's been reset. Do NOT give it a chance to reconnect to your neighbor's device again.


      Step 2: Get your Headphone/Speaker/Receiver.

      Turn it on and get it into Bluetooth Pairing Mode.

      For Avantree Headphones/Speakers/Receivers: The LED indicator on the headphone/speaker/receiver flashing RED & BLUE.
      For Non-Avantree Products: Look it up by Brand.


      Step 3: Turn on the Avantree Transmitter.

      Now you may turn it on. Since your Headphone/Speaker/Receiver is closer in proximity, it should pick yours over your neighbors.
      If it still somehow manages to connect to your neighbor's device... Try step 4.


      Step 4: Do the Pairing Elsewhere.

      Go somewhere that's not in the range of your neighbor's device and try again.
      Of course, there's also the option of knocking on your neighbor's door and ask him/her to turn the device off...

       

      Hope this helps!

    • Issue with Sennheiser aptX Low Latency Headphones

      We have found that Sennheiser's HD-350BT, HD450BT, and CX350BT seem to have connectivity issues with our Trasmitter Adapters.
      Common complaints include:

      • Hard to reconnect
      • Connects but takes a while for sound to come through
      • Transmitter shows it's connected via LL but there's still significant audio lag
      • Cracking noise

      Our testing results have shown that the connectivity issues and the audio lag issue often disappear after a few reconnections.

      Nonetheless, other customers have contacted Sennheiser about this, and Sennheiser have admitted that they have some firmware issues (further confirmed on the three headphones' Amazon reviews).

      If you encounter issues mentioned above, please also contact Sennheiser's customer support and let them know.

    • Netflix / Amazon Prime No Sound in the Headphones

      This is particularly an issue when you're using the Digital Optical Audio output port for the Transmitter Adapter.

      Nowadays, most movies & TV shows have Dolby Digital Sound - Generally speaking, Bluetooth technology can only handle stereo sound and not Dolby, DTS, etc (except for our Orbit/TC580).

      Here's the fix: 

      1. Open Netflix/Prime on the TV first (VERY IMPORTANT)

      Netflix

      Prime

      2. Get your TV remote and press Settings to go to Settings (while in Netflix/Prime)

      Netflix

      Prime

      3. Set your Audio Output to PCM. Here's how to do it with Samsung TV as an example. Go to Sound >> Expert Settings >> Digital Out Audio Format >> PCM

      Netflix

      Prime

      4. Close the Settings and check if you can hear sound on Netflix or Prime Video.

      If the problem persists after all the troubleshooting above, please fill the Toubleshooting Form for No sound/Not working for us to identify the issue faster and solve the problem as soon as we can-

    • Lock Dongles No Sound / Not Working

      If you have something plugged into the HDMI port on your TV, please check and see if the port you're using is a HDMI ARC port. For most TVs, when something is plugged into the ARC port, its other audio output ports will automatically be muted. Please switch to another HDMI port.

      IF you have a sound bar or AVR that's using ARC, please consider switching to Digital Optical instead.

      All set up but can't hear anything through your headphones?

      Please follow the troubleshooting steps below:

      Step 1: Check the LED indicators on each dongle, the TX dongle should be DOUBLE-FLASHING WHITE and the RX dongle should be DOUBLE-FLASHING BLUE. Are they doing that?

      • If YES - Awesome! Proceed to Step 2!
      • If NO - The two dongles have not connected to each other, please connect them. Refer to THIS ARTICLE if you're not sure how.

      Step 2: Turn off one of the dongles. Did the dongle that's still on start to SINGLE-FLASH instead of DOUBLE-FLASH?

      • If YES - Nice! That means the two dongles have properly connected to each other and not something else. Please proceed to Step 3!
      • If NO - Looks like one of your dongles has paired with something else... Please factory reset both of them. Refer to THIS ARTICLE if you're not sure how to reset.

      Step 3: Has the transmitter been properly connected to your Device? Double check with the articles below.


      Step 4: IF your answers have all been YES so far yet there's no sound, it's time to send us an email.

      Please email us at support@avantree.com with a detailed description to your issue, we'll have someone assist you right away.

    • The Receiver Dongle Can't Connect to the Transmitter Dongle

      The two dongles in the LOCK set are "factory locked." This means that they should automatically connect with each other right out of the box (with both devices turned on, of course.)

      If they don't, please follow the steps below to troubleshoot.


      Step 1: Manually Reconnecting them.

      With both dongles turned on, gently tap the "RX" button on the RX dongle. This should reconnect the devices; if not, turn to the TX dongle, and give the "TX" button a gentle tap as well.

      When the devices have successfully reconnected, the LED indicator on the TX dongle should start DOUBLE-FLASHING WHITE and the indicator on the RX dongle should start DOUBLE-FLASHING BLUE.

      If this still doesn't work, proceed to Step 2.


      Step 2: Get both Dongles into Pairing Mode.

      With the dongles turned on, press & hold the RX and the TX buttons for about 5 seconds. You'll see the LED indicators on both dongles start flashing RED & BLUE, indicating that they're in pairing mode.


      Step 3: Keep the Two Dongles close to each other, and give them a few seconds.

      Sometimes it may take up to 30 seconds for the two devices to successfully connect, so please be patient.

      Once successfully paired, you'll see the LED indicator on the TX dongle start DOUBLE-FLASHING WHITE and the LED indicator on RX dongle start DOUBLE-FLASHING BLUE.

      And voila, you're ready to go!

      If you're still confused, you may either refer to one of the Video Tutorials below, or email us at support@avantree.com, we'll have someone assist you immediately.

  • User FAQs
    • Is Avantree Device suppose to come with AC Adapter?

      No, there is no AC adapter in the box. The reasons are:

      1. It is recommended to power the Avantree TV Transmitter from your TV USB, so it will be on / off with TV easily;

      2. Most people have many AC adapters from cellphone and others. For environmentally friendly consideration, we will not include an un-necessary accessory.

      3. FREE AC adapters can be provided upon request within first 30 days of purchase for product over 50 dollars.

       

      The compatible power adapter needs to be with output of 5V 500mA - 2A.

  • Technical Knowledge
    • Different Bluetooth Codecs (Latency.)

      Many Avantree products have incorporated the latest "aptx low latency" codec technology, for superior stereo quality sound without any noticeable delay (known as latency).

      * Important note*

      To take advantage of the better performance of aptX Low Latency codec, the other side Bluetooth device must support the same codec. If the other side device only supports the normal aptX codec, or the SBC one, these codecs will be used instead.       

      How about the audio delay when use different wireless audio codec?

      Wireless audio codec Audio delay
      aptX™ HD ≥ 250ms
      aptX™ Low Latency ~ 40ms
      aptX™ ~ 70ms
      FastStream ~ 40ms
      SBC (most standard Bluetooth audio codec) ~ 220ms


      Note: The latency for FastStream is almost the same as aptX Low Latency, but the audio quality of aptX Low Latency is better.

    • General Bluetooth Information

      Here are a few things you'd want to know about Bluetooth...

      1. Bluetooth by nature is a short-range wireless technology.

      Bluetooth was initially made specifically for wireless headsets hence its “range” was never meant to be anything more than the length of a typical backyard.

      2. Bluetooth Signals are easily interfered with.

      Much like almost any other modern wireless technology, Bluetooth signals can be negatively affected by things like walls, floors, other wireless devices, or even a human body.

      If you want a better range & less interference, try to stay clear of the things mentioned above.

      3. There are two types of Bluetooth.

      In short, they are “Class 1” and “Class 2.”  Class 1 has better range (100m/300ft) but drains your battery faster, whereas Class 2 has a shorter range (10m/30ft) but is more efficient when it comes to battery usage.  

      4. The “Actual Range” depends on a lot of things.

      Things that can affect the range: Bluetooth version, Bluetooth type, Bluetooth profile, Brand & make, where you’re using it, what’s around you… etc and many more. Getting a bad range doesn’t necessarily mean your device is bad; try it elsewhere before you give it a conclusion.

      5. The “Transmitter” and the “Receiver.”

      Every Bluetooth connection consists of a “transmitter” and a “receiver.” The “transmitter” sends the signals to the “receiver.” In a typical Bluetooth headphone connection, your phone is the transmitter and the headphone is the receiver.

      There are cases where one device can do both, but it is unlikely that they’ll be able to do both at the same time.

      Here are some examples:

      • Transmitters: Phone, Computer (can sometimes use as receiver), TV.
      • Receiver: Headphones, Speaker

    • Where to find Batch Number/LOT Number?

      Batch No. or Lot No. is a 4-5 Digit/Alphabet combination (e.g. T22F1, 22B1, or T22J1) printed somewhere on the product. The "somewhere" is usually as follows:

      1. on the bottom of the product;

      2. on the inside of the Headband, just above the Earcups;

      3. on the in-line controls or on a Tag near the 3.5mm AUX Plug;

      Avantree HF027 Silkscreen

      4. on metal head of the adapter;

      Above are some examples that'll give you an idea of what the Batch/Lot Number looks like and where to find them. The print for Batch No. or Lot No. is usually quite small; please consider using a magnifying glass if it's hard to read.
