Features Compliant to IEC 61603-7 and IEC 60914Compatible with
any other IR simultaneous interpretation system compliant to IEC
61603-7 Digital infrared processor with DQPSK digital
modulation/demodulation technology Transmitting in 2~8 MHz
frequency band eliminates disturbance from high frequency lighting
systems Channel selection via up/down button, at most 4,8,16
or 32 channels available LCD display with channel number,
language name, battery and signal status indication Number of
available channels is always the same as the number of channels in
use by the system, eliminating the need to scroll through unused
channelsAdjustable volume Unique 270º super wide reception
angle, ensuring perfect sound quality even when casually
placed Audio signal automatically muted when signal is too
low, ensuring that the user receives only high quality
audio.Ergonomically compact and elegant design Lightweight and
