With Iris beyerdynamic introduces a new, digital infrared interpretation system for wireless multi-channel transmission. It is easy to install and can be operated intuitively. The easy-to-read display, the indicated signal strength and battery status allow comfortable handling and therefore a smooth event. The system makes use of the latest DQPSK digital modulation technology and ensures smooth operation – even outside in direct sunlight.
