standards:
EN50081-1 (1991), EN55022 (1987)
EN50082-1 (1992 and 1994), EN60950-92

Shielded interconnect cables must be employed with this equipment to ensure compliance with
the pertinent Electromagnetic Interference (EMI) and Electromagnetic Compatibility (EMC)
standards governing this device.

FCC COMPLIANCE

This device has been tested and found to comply with the limits for a Class A digital device,
pursuant to Part 15 of the FCC rules. These limits are designed to provide against harmful
interference when equipment is operated in a commercial environment. This equipment generates,
uses and can radiate radio frequency energy and, if not installed and used in accordance with th e
instruction manual, may cause harmful interference to radio communications. Operation of
equipment in a residential area is likely to cause harmful interference, in which case the user will be
required to correct the interference at their own expense.

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. By changing the input jumper, the unit can also be
set for Split Mode where it operates as two independent 1 x 4 distribution amplifiers. The IN3218HR has (4)
gain controls and (2) sharpness controls.

Composite Video Signal Compatibility - While the IN3218HR is most often used with NTSC, PAL or
SECAM composite video signals, it offers extremely wide bandpass characteristics and is also compatible with
high-resolution monochrome signals at virtually any resolution and refresh rate.

Loop Output - The IN3218HR loop output connector provides a passive loop-through signal, allowing the
user to utilize additional amplifiers to create a larger DA system or to drive a local monitor. In order to use the
loop output, the input termination jumper (internal) must be set to High Z (unterminated).

Line Driving - The IN3218HR is designed to extend video signals down long cable runs. The Gain Controls
have an adjustment range of 0.7 (30% decrease) to 1.4 (40% increase). These controls can be used to boost
video signals to compensate for voltage losses caused by lengthy cable runs.

Peaking Controls - have been optimized for maximum effect with NTSC / PAL / SECAM composite video
signals. These controls can be adjusted to compensate for high frequency loss in long cable runs. The peak
controls also enhance video image quality by increasing clarity and boosting visibility of fine details.

The IN3218HR offers high performance, rugged metal construction and flexible video distribution / line drive
capabilities, making it suitable for a wide variety of applications including audiovisual installations, medical
imaging, military simulation, industrial video and tradeshow video systems. The unit features an internal
power supply that is pre-set at the factory for 120 VAC or 230 VAC operation. Two units can be rack
mounted side-by-side in a 1U rack space using the optional IN9080 Rack Shelf. A single unit can be rack
mounted using the IN9080 Rack Shelf and an IN9088 Blank Panel.

Installation

If operating the IN3218HR in Normal Mode without loop output (factory default,) begin with step 2. If
operating the IN3218HR in split mode or with the loop output connector, please refer to INTERNAL
CONTROLS section on page 3 and set the appropriate jumpers.

1. Place / install the IN3218HR at the desired location. Make sure that the unit is seated on a flat surface

or is securely installed in a standard 19” equipment rack using an IN9080 rack shelf (optional).

2. Connect the video signal from the source to the IN3218HR input.

3. Connect the output(s) to the display device(s) or other equipment.

4. Apply power to the unit using the IN9230 IEC Power Cord (U.S. only).

5. Adjust gain and peaking controls as needed (see the GAIN AND PEAKING CONTROLS section on

the following page).
