Operate four microphones at once.

This system includes two dynamic cardioid Handheld Microphone Transmitters, two Bodypack Transmitters with Lavalier Microphone and one UHF-4288 4-Channel Receiver. Handheld transmitters feature quiet On/Off switching and LED indicators for battery and power. Lavalier microphone features omnidirectional pattern with a condenser element for clear, sensitive pickup. Bodypack and handheld microphone transmitter use 9V battery (extra).

The dual antenna receiver offers true diversity reception for each of the four channels, allowing the best possible signal. With four independent receivers on each channel, you can plug in and operate up to four microphones without interference. Delivers excellent dynamic range for warm, natural-sounding speech and vocals. Saves valuable input space on your sound system by connecting up to four microphones from one mixed balanced XLR or unbalanced 1/4" output. A squelch adjuster on each channel helps fight RF interference and unwanted background noise for a clean, interference-free signal. Dimensions: 19"W x 1-1/2"H x 12"D.
