What to do if my Karaoke USA Microphone has sound interference?
If your Karaoke USA Microphone is experiencing sound interference, it might be due to other wireless devices such as other wireless microphones, TVs, microwave ovens, or radios. To resolve this, change the microphone's frequency.
Why is there no sound from my Karaoke USA WM906 Microphone?
If you're experiencing a lack of sound with your Karaoke USA Microphone, there are several potential causes: * Ensure both the microphone and receiver are powered ON. * Check the amplifier volume and increase it if it's too low. * The microphone and receiver may need to be re-paired (refer to index No. 9). * Low battery can cause this issue; charge both the microphone and receiver.

The Karaoke USA WM906 is a dual UHF handheld dynamic wireless microphone system designed for various audio applications, including orchestra, band, and stage theatrical performances. This system utilizes a PLL (Phase Locked Loop) synthesized wireless microphone set with a 16-bit Digital Pilot ID, ensuring quick frequency pairing and preventing interference or drifting between multiple transmitters and receivers. This advanced technology allows for the use of multiple dual microphone sets in the same location without experiencing cross-talk or interference, making it a versatile choice for professional and recreational use.
The WM906 system comprises two wireless microphones (transmitters) and one receiver. Each microphone is a handheld unit featuring a dynamic capsule, designed to capture clear and robust audio. The receiver is a compact unit that plugs directly into a microphone jack on a karaoke machine, amplifier, or other electrical components.
The core function of the system is to provide wireless audio transmission, freeing users from the constraints of cables. The UHF (Ultra High Frequency) band, specifically 900 MHz, is utilized for reliable and stable signal transmission. The PLL synthesis ensures frequency stability, while the 16-bit Digital Pilot ID facilitates automatic pairing and prevents unwanted interference from other wireless devices.
The microphones are equipped with several controls to enhance the user experience. These include a power on/off button, volume up and down controls, and echo effect adjustments (echo up and echo down). The echo feature allows users to add a reverberation effect to their voice, which is particularly popular in karaoke and vocal performances. Additionally, each microphone has a channel selector, offering 10 preset channels. This feature is crucial for addressing potential interference from external sources such as TV stations or other devices operating on similar frequencies. If interference is encountered, users can easily switch to a different channel to maintain clear audio.
A dedicated pairing button on the microphone is used to establish or re-establish a connection with the receiver. This ensures that if the connection is lost, or if the receiver's light does not illuminate, the user can quickly re-pair the devices.
The receiver's primary function is to receive the wireless audio signal from the microphones and output it through its 6.3mm (1/4 inch) male plug to an audio system. It also features a power on/off switch and indicators for power, battery status, and receiving signal.
The WM906 system is designed for ease of use, starting with its quick setup. Both the microphones and the receiver are equipped with built-in rechargeable Lithium-ion batteries, eliminating the need for constant battery replacement.
To begin using the system, users must first ensure that both the microphones and the receiver are fully charged. Charging is straightforward, using the provided USB charging cables. A full charge for both components typically takes about 1 hour, providing up to 6 hours of normal use.
Once charged, the receiver's 6.3mm (1/4 inch) male end is inserted into the microphone jack of the desired audio equipment, such as a karaoke machine or amplifier. The receiver's power switch is then slid to the "on" position, and its power indicators will light up.
Next, the microphones are turned on by pressing and holding their power on/off buttons. If the microphones and receiver are not automatically paired (indicated by the receiving light on the receiver not illuminating), a simple re-pairing process can be initiated. This involves turning off the receiver, turning on the microphone, pressing and holding the microphone's PAIRING button until its light flashes, and then turning on the receiver. The devices will then automatically pair.
During a performance, users can adjust their microphone's volume using the VOL+ and VOL- buttons on the microphone itself. The ECHO+ and ECHO- buttons allow for real-time adjustment of the echo effect, enabling singers to customize their vocal sound. If feedback occurs, users are advised to lower the microphone volume or move the microphone away from the speakers.
The channel selection feature is a key operational advantage. If interference is detected, pressing the CHANNEL button on the microphone cycles through the 10 available preset channels, allowing the user to find a clear frequency.
The system's design allows for multiple dual microphone sets to be used in the same location without interference, making it ideal for events requiring several performers or multiple microphone setups.
Proper care and maintenance are essential to ensure the longevity and optimal performance of the WM906 wireless microphone system.
Charging: Regular charging of both microphones and the receiver is crucial. The built-in Lithium-ion batteries provide convenience, but consistent charging after use will ensure they are ready for the next session. The USB charging cables provided are specifically for this purpose.
Physical Protection: The microphones feature a grill that protects the inner microphone cartridge. Users should handle the microphones with care to prevent physical damage, such as dropping them on the floor or bumping them against hard objects, as sudden shocks can damage delicate internal components. Similarly, the receiver should be protected from physical impact.
Battery Management: For extended periods of non-use, it is recommended to remove batteries from the microphone bodies to prevent potential battery leakage, which can damage the internal components. When the batteries reach the end of their life or need to be disposed of, they should not be thrown into fire, garbage bins, or domestic rubbish. Instead, they must be disposed of properly according to local ordinances and regulations for battery recycling.
By following these usage and maintenance guidelines, users can ensure that their Karaoke USA WM906 dual UHF handheld dynamic wireless microphone system provides reliable and high-quality audio performance for many years.
