LD Systems U304.7 BPH

The LD-Systems U304.7 BPH is a radio system with bodypack and headset for a frequency range of 470 - 490 MHz.

Developed in Germany, the U300® series of UHF diversity radio systems offer LD-Systems convincing audio performance. They achieve a range of 100 m under ideal conditions and are available for operation in 5 frequency bands:

  • 584 MHz - 608 MHz
  • 655 MHz - 679 MHz
  • 823 MHZ - 832 MHz + 863 MHz - 865 MHz
  • 470 MHz - 490 MHz
  • 514 MHz - 542 MHz

Six U300® systems can be used simultaneously. A convenient one-touch synchronisation of transmitter and receiver via infrared provides a fast, trouble-free radio connection, and the squelch function with pilot tone ensures interference-free operation.

The U300® Series wireless systems have a fresh, modern look and are available as vocal sets with a receiver and a dynamic hand-held microphone with cardioid characteristic, bodypack and headset or bodypack and lavalier microphone. The U500® series replacement capsules can be used to change the handheld microphone characteristics. U300® Instrument Sets are available with a bodypack and clip-on microphone for wind instruments or a double-shielded low-capacity cable for guitars and basses.
