Transmitter »PRO IR-202«
Infrared emitter and modulator unit for medium sized rooms
The »PRO IR-202« two-channel infrared emitter combines infrared modulator and emitter technology into a single mountable enclosure - which reduces operating costs, eliminates the need for rack space and eases set-up.
The »PRO IR-202« is ideal for high-quality audio programs such as music, theater and audio description. The »PRO IR-202« will accept any line level, balanced or unbalanced audio inputs.
Infrared receivers detect the transmission and convert the light signals back into audio signals. The 2.3/2.8 MHz operating frequencies minimize interference caused by high-efficiency lighting equipment.
A further »PRO IR-202« emitter can be connected for additional coverage area. Power and audio signal are shared between the emitters via the according connection cables. All necessary cables are included.
The transmission energy of PRO IR-202 Transmission/ Modulator unit (Master) is spread in a club-shape in the room with a broad aperture angle (see illustration bottom right). The audio transmission is interference-free due to the infrared signal modulation in 2.3 and/or 2.8 MHz.
If two transmitters are aligned one above the other and »facing the same direction«, the throw distance increases. The horizontal coverage corresponds to that of a single transmitter.
If two transmitters are aligned on top of each other and twisted in the horizontal axis, the horizontal coverage increases. The throw distance corresponds to that of a single transmitter.
A set for ceiling and wall mounting is included in the package.
Combined operation
Combining two PRO IR-202 is achieved with the included installation kit. The units mounted on top of each other can be freely turned to the required angles to achieve optimal signal supply in the room. The range of the Master with 2 Slave units is up to 560 m² at one-channel transmission – ideal for large rooms.
With the selection of the suitable receiver type (RCI-102, PR-22+ or IP112) the range can be further influenced, depending on the sensitivity of the receiver diodes.
