General

Endlessly easy to use for anyone from beginner to industry professional, the LD Systems U300 Series U304.7 in-ear monitor system operates on the 470 - 490 MHz frequency band. Offering users virtually unrestricted freedom of movement, the U304.7 IEM scores great when it comes to frequencies and wireless connectivity, as the system boasts a 100-metre range and a 50Hz to 16kHz frequency response and can be used in combination with a maximum of five other IEM systems without the risk of any signal interference issues.

The LD Systems U304.7 IEM

Inside the box, you'll find a transmitter equipped with 12 channels, 10 mW of RF transmission power, and two jack/XLR combo inputs round the back. The U304.7 system can be used in mono or stereo mode with the ability to independently adjust the left and right channel, and the receiver can be connected using a universal mini-jack cable. A display has even been thoughtfully integrated into the bodypack so you have immediate access to channel information, battery status and stereo mode. Please note that the system comes complete with 19" rack mount kit.
