Features:

• Offering 4 channels of independent programming, the IR System 400 is the professional choice of reliable, easy-to-use and affordable multi-language and simultaneous translation applications.
• 4 channel emitter/transmitter; IR-405: Control panel for IR-400; IR-410: 4 channel selectable (A/B/C/D) headphone receiver
• Utilizes advanced state-of-the-art PPM (Pulse Position Modulation) IR technology (@300-900KHz). The 4-channel signal modulates a sequence pulse code as a sub-carrier which then modulates the infrared carrier directly. This innovative technique offers clearer audio and superior interference-free transmission than earlier narrow-band FM modulated IR systems.
• IR-400 can transmit 4 independent channels of speech or music to any number of IR-410 receivers which can all select any of the 4 channels as needed
• Can be wall mounted or on optional tripod for table or floor setups.High gain IR-LED (light-emitting diode) emitter panel with built-in amplifier; modulation input: sync output for daisy chaining with up to ten more IR-400 transmitters for extended coverage; and a DC input for powering by an external AC/DC adapter (28V DC @ 1.6A)
• IR-405 features: 4 selectable Audio In or MIC In inputs with volume control; separate Mix Input; built-in ALC; 3 headphone out jacks to allow 3 listeners to monitor the channel 1 signal (e.g., such as interpreters for channels 2, 3 and 4); peak audio level LED indicators for each of the 4 Audio In and MIC In signals; a signal out for modulating the IR-400 transmitter; and a DC input for powering by an external AC/DC adapter (12V DC @ 200mA)
• IR-410 headphone receiver features: ultra IR light-sensitive diodes for optimum reception and maximum range; 4-channel select switch; individual volume controls for each ear; 2 X AAA battery operation; adjustable headband for comfortable universal fit
