Install the WX-US Wireless Receiver


When your sound system is on, speakers often have what is called “white noise” particularly when the treble control is turned to the high position. This is not a defect but is a function of the electronic design that allows our sound systems to produce satisfactory audio levels with high battery efficiency.
Flip the systems power switch on and check the battery indicator light. If the LED light does not turn on or is flashing, then your battery needs to be recharged. Simply plug the system into a nearby outlet using the systems power cord. Leave the system charging overnight for a fully charged battery the next day. You can still operate the sound system while it is charging. To learn more on how to take care of your systems battery, from maintenance to replacing the battery yourself, we recommend checking out the “How To” section on our youtube channel.


First check that the AA batteries in your handheld microphone or belt pack are good. You can quickly do this by turning on your mic or belt pack and noting whether the red LED light flashes once and stays on, indicating good batteries. If the light does not flash at all or continuously flashes then the batteries need to be replaced.

If your microphone is still not working, double check that you have matched the frequency number on the mic or belt pack with the same frequency number on your sound system.

We are committed to our customers and our products, and we feel strongly that Anchor Audio portable sound systems should have a long life. Click here to learn more about our 600 MHz product upgrade program. It will take effect January 1st, 2018. You can enter your information in the form and we will let you know if your product is eligible for the upgrade.
The best way to get rid of interference is to try a different frequency channel on your sound system and dial in the same frequency on your microphone or belt pack. With up to 16 channels to choose from you’re sure to find a clear channel.
Move further away from the sound system when using your microphone. You can roam up to 200 feet away with a wireless mic, just be sure to turn the mic off when you approach the unit to change out CDs or adjust the volume. Please also remember not to stand directly in front of your system, as this can also cause feedback.
Place your sound system approximately 10 feet from the first row of the audience and in the center of the room or field, see below illustration. The speaker should be at the head-height when facing the audience. If you are using a companion speaker to cover a large crowd, place the speakers on either side of the stage or presentation area for the best distribution.

Yes! By using the line output feature on the back of the AN-Mini, simply plug in any 3.5mm stereo cable to the AN-Mini’s line output connection and the other end of the cable into the second AN-Mini’s line input. Repeat this step for adding more AN-Mini systems. IMPORTANT: When connecting multiple AN-30 units (daisy chaining) a stereo cable MUST be used to avoid interference.
As of August 1st, 2014, in the USA, Anchor Audio wireless products operate in the 540-570 Mhz range. All 8000 and F1 series products with wireless capabilities will have this frequency. Prior to August 1st, 2014, Anchor Audio wireless products were manufactured and operate in the 682-698 MHz range. This corresponds with products in the 7500 and U1 series. In Europe our products operate in the 863-865MHz range.
The gain knob controls the sensitivity of the mic. Because various mics with different sensitivities can be used with the wireless beltpack, the gain knob allows all of them to be calibrated for the right situation. In addition, people speak at different volume levels and the gain knob can be used to adjust for that as well. If the system volume is all the way up and you are still not loud enough, simply use the key to turn the gain knob clockwise. If you are too loud or you are hearing distortion, turn the gain knob counter-clockwise. Wireless beltpacks are shipped with the gain set at halfway.
Please refer to your system manual (can be found on the product page for each product) for general battery maintenance and use instruction. If your battery has retired and needs to be replaced, please review our videos on at-home battery replacement, or call our technical support at (800) 262-4671 Ext. 782. We find that simply purchasing replacement batteries and following the instruction in our specialized videos is often the easiest choice for our customers.

Yes, the Lithium Iron Phosphate batteries used in Anchor Audio products are safe. Lithium Iron Phosphate batteries are different and much safer than the Lithium batteries that have been in the news recently relating to hover boards and phones. Lithium Iron Phosphate energy density is much lower than conventional Lithium batteries which makes them inherently safe. In fact, there are just as safe as the Sealed Lead Acid batteries that we have used for many years. In addition, we have been able to successfully navigate all regulatory hurdles so that there are no shipping restrictions or additional charges. We have assured that our batteries have passed all safety requirements, including UN 38.3, CE, IEC 62133, and UL 1642.As an extra measure of safety and quality, each Lithium battery pack has its own battery management system (BMS). This prevents the battery from undercharging, overcharging, over-discharging, and overheating. The BMS also keeps all the cells balanced which prevents the cells from drifting and harming its long-term performance.
Simple! An 8000X, 8000XU1, and 8000XU2 (Liberty & MegaVox) include a built-in transmitter – as designated by the X. This transmitter operates on the 902 – 928 MHz frequency, with 100 user-selectable channels. The AIR wireless companion speakers have a built-in receiver which, when set to the same channel as the transmitter, picks up the audio signal.
Yes, absolutely. Any 8000X, 8000XU1, or 8000XU2 can transmit to an unlimited number of AIR wireless companion speakers. All units should be set to the same frequency to receive signal. When setting up your arrangement, be sure to point the systems facing the same direction – pointing the systems directly at one another may cause distortion. AIR units can be placed 300+ feet (or more in ideal conditions) from the transmitting main unit.
Yes! All AIR units have what we call ‘Wired Mode,’ which allows the AIR wireless companion speaker to be used just like an unpowered wired companion speaker. Power and audio signal are sent from the main unit to the AIR companion speaker with a cable. Simply power off the companion speaker, flip the switch into ‘Wired Mode,’ plug in your speaker cable (SC-50NL for Liberty, SC-50 for MegaVox), and the main unit will power the companion.
Each AIR can be placed up to 300+ feet from the main unit transmitter. In ideal conditions, you can place the systems further, however, be aware of physical latency and/or interference. If you are using multiple AIR systems, be sure to center the main unit between all AIR companions.
Oh no! You have a few options. First, try to change the channel. There are 100 channels to choose from, so be sure to try various frequencies to find a clear channel. You should also double check that your speakers are close enough together to have a strong signal. Be sure all your batteries are fully charged. Additionally, verify your inputs all have a clear signal (such as a wireless microphone, cables, and Bluetooth). Lastly, you can try adjusting the external antennas for a better connection. These fixes may not work for everyone, as there are occasional signals which cannot be avoided (for example being close to a high-power cell tower). In this situation, you can use your AIR companion in ‘Wired Mode’. If none of these fixes work, please call us. We are happy to help!

Yes! For the Beacon, Liberty, Go Getter, and MegaVox, you can connect your two main units (one unit must have a built-in wireless receiver) using the following directions

  1. Using a 6000-14P cable, connect a WB-8000 beltpack to the line out port of your unit
  2. Match the wireless channel (1-16) on your WB-8000 to the wireless channel on the other main unit’s wireless receiver
  3. Ensure that both frequencies are the same on the beltpack and your other unit. Enjoy!

The Bigfoot is a little different, but you can still wireless connect the main units using the following directions.

  1. Plug WB-9000 into main unit using 6000-14P into line out port
  2. Plug ALB-9000 into secondary unit using Mini-15 (AUX cable) into line in port (set to line level)
  3. Make sure both beltpacks are set to the same frequency
Actually, yes! An 8000X, 8000XU1, and 8000XU2 (Liberty & MegaVox) will transmit to the AIR companion speakers as well as the ALB-9000 Assistive Listening beltpack(s). Since all systems are shipped out by default on the 902.000 channel, simply power on your transmitter and receivers (beltpacks and AIR wireless companion), and you instantly have an ADA compliant sound system. Did you know that ADA requirements mandate compliant assistive listening systems for any theater using audio amplification or with a capacity of at least 50 audience members? Try this set up for the easiest solution.
