The LD-Systems U308 BPW is a radio system with bodypack and wind instrument microphone at a radio frequency range of 823 MHz - 832 MHz + 863 MHz - 865 MHz.
Developed in Germany, the UHF diversity radio systems of the U300® series offer 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.
The LD-Systems U300® transmitters have an output power of 10 mW and 10 hours running time with two AA batteries. The frequency response of the handheld microphone ranges from 55 Hz - 16 KHz, and with a lower cutoff frequency of 25 Hz, the Bodypack is also suitable for transmitting 5-string bass guitars with a low B string. The bodypack's input level can be adjusted in three levels to suit active and passive guitars and basses, and the convenient standby position of the power switch allows temporary muting.
The U300® receiver is equipped with a bright LCD channel display, an LED chain to indicate the audio signal strength and a balanced XLR and unbalanced 6.35 mm jack output. The jack output can be switched to instrument level for direct connection to guitar and bass amplifiers.
