The IR-100 is the centerpiece of the infrared remote control system. A system wiring connection block where the power supply, IR repeaters, and IR flashers all tie together. The IR-100's advanced circuitry adjusts the incoming repeater signal levels and the outgoing flasher output levels for optimum remote control system performance. The IR-100's computer designed signal amplification circuitry allows long cable runs to work as well as short cable runs. A repeater 1000' away from the IR-100 will flash the controlled A/V equipment exactly the same as a repeater 10' away will. The IR-100's flasher outputs are regulated to an optimum output level. Flashers will never flood the device under control causing missed commands and they will never reach out far enough to effect another device even if it uses the same IR codes. An advantage of regulated short range flasher output levels is that you can use multiples of the exact same component in multi-zone system designs, in the same equipment rack and experience no IR remote control problems.
