The LD Systems U506 HHD is a true diversity UHF wireless microphone system which includes the U506R receiver and U506MD hand held wireless microphone transmitter with shock-mounted dynamic mic capsule.

The system operates on UHF frequency range 655 - 679 MHz (Interleaved Spectrum, licence required) with up to 12 systems running simultaneously.

The LD Systems U500 Series wireless microphone sets were developed in Germany and offer affordable professional technology, impressive performance, reliability and sound quality.

An operating range of up to 100 metres is possible, but a 3 step transmission power switch on the transmitter facilitates the best balance between optimum battery life and required range of operation.

The U506HHD system is easy to use with an automatic scan facility which finds the best free frequency, and convenient one-touch infrared synchronisation of transmitter and receiver for easy set up.

The U506MD handheld transmitter comes complete with a dynamic microphone capsule which is great for on-stage live vocals to keep feedback to a minimum. The transmitter body has a high contrast OLED display with convenient battery status indication. Low power consumption enables the transmitter to run for up to 10 hours with 2 x AA batteries whilst an adjustable gain function (from 0 to -27 dB in 3 dB steps) prevents clipping of the input with very loud and strong voices, for a clean and crisp sound.

The U506R receiver also has a high-contrast OLED display which shows all the relevant information such as user name, transmitter battery status, radio signal, active antenna, audio signal strength and radio frequency.

Individual usernames can be entered on the display to keep track of active microphones.

To deliver superior audio quality and prevent interference and broadband noise, the U500 wireless systems feature a squelch function and pilot tone which is sent from the transmitter along with the audio signal. It is outside the frequency range that humans can hear, but if this tone is not present at the receiver, for example, when the mic is switched off, the receiver is muted automatically.

Other microphone configurations are available in the U506 wireless systems – see related products for the tie clip microphone option.
