Wireless speakers just like any other consumer products are destined to fail at some point. In this post, I will show some methods for troubleshooting a pair of wireless speakers and also offer some simple strategies for inspecting and repairing a speaker.
Next I will show you what to check when your speaker quits. It is best to follow this guide step by step http://itsnews.co.uk/. First, double check that there is no problem with the speaker power supply. Some wireless speakers can be powered by batteries. If you have such a speaker then check that the batteries are fresh. Replace the batteries if necessary. Some speakers also can be powered by using an external power supply. Try using this type of power supply if available instead of batteries. There may be some indicator on the speaker showing if power is available. The transmitter base is another possible cause for the speaker not having any sound. Make sure the transmitter has power. Also, double check the audio connections between your source and the transmitter. To check that the transmitter receives audio, you’ll need another audio gadget. An audio amplifier would be perfect for doing this test. Simply connect the input of the audio amp to your source using the same connecting cable.
If you have double checked both that the speaker has power and that there is no issue with the transmitter then your speaker very likely is defective. You should check if there is still warranty on your speaker. If so then you can just return it to your HiFi vendor for repair. Instead of returning the speaker to your dealer, you can also return it to a repair center. Be sure to contact your vendor to get shipping instructions. If the warranty has expired then you won’t be able to get the speaker repaired under warranty. If you don’t want to spend money on getting the speaker repaired you can consider getting a replacement. Some vendors offer inexpensive refurbished products. Alternatively, you can try to fix the speaker yourself if you have some technical knowledge.
The first step in repairing your speaker is opening the speaker enclosure. Locate and remove all of the screws holding the enclosure together. Make sure to remember the location of each screw. If you have a speaker that is powered by the mains voltage, locate the speaker power supply. To verify that the power supply is OK, measure each of the voltages that are generated. You can use a multimeter or oscilloscope to measure the voltages. Compare the measurements to the voltage ratings which are usually printed on the power supply circuit board. Most likely there is a power fuse on the board. Use the multimeter to check that the fuse is still OK. If the fuse has blown, replace it with another fuse that has a similar current rating as the original fuse.
The next step is to check the wireless RF module. This module receives the wireless signal and generates analog audio which is fed to the integrated power amplifier. Simply check the audio signal coming from this module to verify that this module works OK. If you are having trouble spotting the wireless receive module, look for a structure that looks like an antenna. The antenna is connected directly to the receive module. After you have verified that this module is OK, it is time to inspect the amplifier board of the speaker. The amplifier module converts the low-level signal from the receive module to a large enough signal to drive the internal woofer and tweeter. Testing the amplifier board is fairly simple. Just measure the amplified audio signal that is generated by the amp. If there is no sound coming from the amplifier then the amplifier is defective. Often you can get a replacement amplifier from the manufacturer or an authorized service center for replacing the old module.
For decades, speakers have carried an ominous association with wires, much like phones were in days gone by. Stereo owners were always well acquainted with wires. The speakers could only go as far as the wires went and where the wires went, they could be seen. As with other wired devices, hiding speaker wires usually meant drilling holes in the wall or floor. This made moving the speakers difficult because you’d have to move the wires too.
The advent of home theater introduced even more wires into the home environment. Rather than just two speakers (as with a stereo), home theaters call for six or more speakers, all with wires! This not only made setting up a home theater difficult, but it made the room look messy with all those wires. Traditional methods were used to hide the wires and we all got used to them, until they came out with wireless speakers, of course. Now you can place speakers where you want them. If you want to rearrange them, you can right because as long as you can find a place to plug them into power, you’re good.
This leads us to one of the obvious advantages of wireless speakers: convenience. No longer must holes be drilled in the floor and wires run every time you want to set up something new. If you want to change rooms, it’s a piece of cake. Wireless speakers are convenient.
The other reason that leads people to wireless speakers is visual appeal. No longer do you have to love with unsightly wires that destroy the aesthetics of you house. You can place your speakers anywhere you want them without having to worry what to do with the wires.
