The Kam Quartet Eco is a premium UHF wireless microphone system that has a UHF Multi-channel receiver and four handheld dynamic cardioid microphones.

The receiver's metal housing makes it ideal for use on the road, and it has a good signal-to-noise ratio and almost no noise emission while it's not being used. Separate volume knobs and RF/AF signal indicators are located on the front, while the device's back has a balanced audio output and an unbalanced audio output in addition to two antennas.

There are four long-lasting, colour-coded wireless handheld professional microphones with On/Off switches that may be used up to 60 metres away from the receiver without interference.
