The RM-20 has been designed to provide IR remote control signal distribution for up to 20 VTRs without modification or conversion of any kind. Since its 20 outputs are buffered, each VTR receives its own IR signal via a cable with an IR LED attached. This LED is placed directly in front of the VTR's IR sensor. It must be used in conjunction with our MRM-100/5 INFRARED MASTER REMOTE CONTROL (below). RM-20 units can be looped to control up to 500 VTRs from a single MRM-100/5. The RM-20 can also be controlled from a modified hand held remote control. The RM-20 is perfect where consumer or prosumer type VHS VTRs are used in real-time duplication facilities. The RM-20 will only operate with the MRM-100/5 or a specially modified handheld IR transmitter..
