»PRO IR-400« – high-performance infrared transmitter: Two-channel transmitter for the supply of large rooms and halls
The two-channel infrared emitter PRO IR-400 combines the modulator and emitter in one single unit. This design saves costs and can be mounted in limited spaces.
The infrared light exists in a wide angle, which spreads efficiently throughout the supplied areas in the club-shape typical for this transmission method.
The steady transmission of the PRO IR-400 is realised at a working frequency of 2.3 and 2.8 MHz without the interference of ambient light. In 1-channel mode, the emitter supplies areas of up to 900 sqm. Adding further PRO IR-400 emitters into the setup allows the receiving range to be expanded easily. The package includes an attachment set for wall and ceiling.
Expanding the system
If the coverage of a larger room is required (for example a conference hall), it is possible to connect further »PRO IR-400« emitters (Slaves), linked to the primary emitter (Master). The devices are linked by connecting the according Sync-Out-ports of the first emitter to the Sync-In-ports of the next emitter.
Receiving and listening components
For the reception of the infrared transmitted audio signals and for the conversion of the infrared signal into audible sound appropriate receivers are necessary – for example the underchin receiver RCI-102, the pocket receiver PR-22+ for the connection of all commercially available headphones or the IR receiver headphones IP-112.
