The KOMISON KMS-IEM420 UHF MONO Wireless In Ear Monitor System is designed for stage performance, speech, studio, and other large-scale live events. With 80 adjustable frequencies, it provides a clear and high-fidelity audio experience without any latency.

In the event of static, distorted, or cutting-off sounds, several troubleshooting steps can be taken: 1. Frequency interference may be the cause. Adjust the bodypack and transmitter to a new frequency. 2. Ensure all cables are properly connected. 3. Confirm the user is within the operating range. 4. Replace the bodypack battery with a new one and test again.

If there is no sound from the transmitter or receiver (bodypack/beltpack): 1. Check if the earphone is functioning and properly connected. Try a different earphone. 2. Adjust the volume on both the transmitter and the bodypack. 3. Ensure the transmitter and bodypack are set to the same frequency (channel), as they will not work otherwise.

For static or unsatisfactory sound quality: 1. The IEM system must be connected to other audio equipment, such as a music player, audio mixer, amplifier, or microphone. Check the settings and cables of the connected components and test again. 2. Try a different professional IEM earphone.

The KOMISON IEM Series includes several models: - IEM420-4 bodypacks - IEM430 - IEM420-2 bodypacks - IEM420-1 bodypack

These models are compatible with KOMISON IEM-420 and IEM-430 transmitters and offer the following features: - Metal construction for the transmitter to ensure durability - Relatively small and refined bodypack with independent volume control, pause, and frequency adjustment functions - A metal clip on the back of the bodypack for convenient carrying

The wireless system operates on 80 channels, divided into 8 groups of 10 channels each, allowing for faster and easier frequency adjustments between non-adjacent channels. This feature helps to mitigate interference and ensure clear, pure sound.

The advanced circuit design and upgraded chips in this IEM system improve the signal-to-noise ratio, providing clear and high-fidelity audio without latency, as well as stable signals. However, if there are any issues with noise or static during use, it may be caused by interference, and changing the frequency may resolve the problem.

The package includes: 1 x UHF wireless transmitter, 4 x bodypack receivers, 4 x in-ear earbuds, 1 x power adapter, 1 x antenna, 2 x 6.5mm to 6.35mm cables, and 1 x user manual.
