Installation and Safety Instructions For Models without a Power Switch: The socket outlet shall be installed near the equipment and shall be accessible. For all Models: No serviceable parts inside the unit. Refer service to a qualified technician. For Models with Internal or External Fuses: For continued protection against fire hazard, replace only with same type and rating of fuse.
1 Product Overview DESCRIPTION The IN3218HR is a high performance video distribution amplifier / line driver offering 300 MHz bandwidth performance. The unit is commonly used to amplify and split the signal from one video source out to several monitors, projectors, VCRs and / or other output devices. Eight Buffered Outputs - In Normal Mode the IN3218HR is a one-in eight-out video distribution amplifier that can simultaneously drive up to eight output devices.
2 Operation The IN3218HR is designed to distribute / extend video signals. The unit features gain and peaking controls which can compensate for signal loss (associated with long cable runs), extending a video signal as far as 800 feet with minimum degradation. Actual drive distance depends on the resolution of the signal and the quality of the cable used. Typically, low-resolution video signals (15KHz) can be sent 600-800 feet, and highresolution signals (30 KHz and above) can be sent 200-400 feet.
3 INTERNAL CONTROLS CAUTION: Adjustment of the IN3218HR internal controls must only be carried out by qualified technicians. Care must be taken to avoid static shock to the internal components. 1. Remove the screws from the sides of the unit. 2. Slide the top cover off. 3. Identify the location of the jumpers using the diagram below and adjust as needed. 4. Replace the top cover and tighten the side screws.
