LD Systems U300 In-Ear Monitoring System with Earphones

Easy to use, with reliably clear audio, LD Systems U300 in-ear monitoring system runs 10 hours on two AA batteries, and includes rackmount kit and earphones.

LD Systems developed the U300 wireless in-ear monitoring system for unlimited freedom of movement on the stage with perfect in-ear monitor sound at all times. Developed in Germany, their clear, modern design and straightforward operation make them the perfect choice -- not just for beginners. Their reliable range of up to 100 m and low-reaching frequency band of 50 Hz to 16 kHz ensure professional performance.

The in-ear transmitters offer a choice of 12 transmission channels and an RF transmission power of 10 mW. They can also be operated in mono or stereo mode. Combo sockets serve as symmetrical XLR and asymmetrical 6.35 mm jack inputs. Left and right input levels can be controlled separately, while two LED chains indicate audio signal strength.

The bodypack receiver has a mini jack socket to connect the earphones as well as displays for channel, stereo mode and low battery status. Running on two AA batteries, it has an operating time of 10 hours. A practical controller allows individual adjustment of the monitoring volume during performance. 19" rack assembly kit included.
