Introduction
The IN3212™ and IN3214™ are high performance composite video
or (for IN3214 only) S-video distribution amplifiers with gain and
peaking controls. The IN3212 features 300 MHz (-3dB)
bandwidth and the IN3214 features 280 MHz (-3dB) bandwidth.
The compact design allows them to be installed in any convenient
location. They accept NTSC, PAL, and SECAM video signals, as
well as high resolution monochrome, and distribute the signal to
separately buffered outputs.
Both models are powered by an external 110V or 220V power
supply. The power supply included with each unit is appropriate
to the region where the DA is sold.

Features
• Two (IN3212) or four (IN3214) outputs — Distribute a video
signal from a single input to two or four outputs.
• Gain and Peaking controls — Compensate for long cable runs
and increase fine details and clarity.
• Quad-standard compatibility — Compatible with composite
NTSC 3.58, NTSC 4.43, PAL, and SECAM video as well as high
resolution monochrome video signals.
• Split mode operation (IN3214) — Can be functionally split
into two independent two-output distribution amplifiers.
• Local monitor loop-through — Provides a passive loopthrough signal for a local monitor, or to create a larger DA
system.
Normal and Split Mode (IN3214 Only)
The IN3214 can be configured to either normal mode or split mode.
• Normal mode (factory default) — A single 1-input by 4-output
composite video distribution amplifier (figure 1).
In this mode, the Loop Out/Input 2 connector can be jumpered
as a loop-through to provide a buffered local output signal.
• Split mode — Two, independent 1-input by 2-output DAs.
Composite video — The DA can accept two composite video
inputs and distribute eachinput to two separate outputs.
If a loop-through signal is required when the IN3214 is
configured for split mode and is buffering composite video, set
the inputs for High Z (see the jumper table on page 5) and use
a BNC “T” connector on the input to split the signal.
S-video — The DA can accept a single S-video input (with the
luminance [Y] input on one input connector and the
chrominance [C] input on the other) and distribute the Y/C
output to two separate S-video devices (figure 2).

Installation
1. Turn off and disconnect all equipment.
2. If necessary, reconfigure the internal jumpers for the desired
mode and Loop Out/Input 2 connector termination. See Normal
and Split Mode (IN3214 Only) and Jumper configuration.

3. Place the DA in the desired location or mount it in a convenient
location using the optional mounting brackets.
4. Connect the input device(s) to the input connector(s).
5. Connect the output devices to the output connectors.
CAUTION
6. Apply power to all devices and turn on the input and
output devices.
7. Adjust the gain and peaking as needed. See Connections and
Controls.
Jumper configuration
The DA is factory configured in normal mode (IN3214 only) with
the Loop Out/Input 2 connector terminated (no loop-through).
For any other type of video, reconfigure the jumpers as follows:
1. Remove the screw on each side of the cover (figure 3).
Remove the four
hex nuts.
Figure 3 — Opening the DA
2. Using an Extron BNC extraction tool (part #100-096-01) or a
14mm, deep well socket, remove the four hex nuts securing
the output BNC connectors to the rear panel. Slide the
cover forward until the cover clears the BNC connectors.
Lift the cover off.
3. Locate J2 through J5 on the printed circuit board (figure 4).
4. Set the jumpers as shown in the table on the following page.
4
5. Replace the cover and reinstall the screws.
Ensure you are using the correct power supply, 110V
or 220V, for your region. Using the wrong power
supply will damage the DA.

2. Hold the unit with the attached brackets against the
underside of the table or other furniture. Mark the location
of the screw holes of the bracket on the mounting surface.
3. Drill 3/32” (2 mm) diameter pilot holes, 1/4” (6.3 mm) deep
in the mounting surface at the marked screw locations.
4. Insert #8 wood screws into the four pilot holes. Tighten
each screw into the mounting surface until just less than
1/4” of the screw head protrudes.
5. Align the mounting screws with the slots in the brackets
and place the unit against the surface, with the screws
through the bracket slots.
6. Slide the DA slightly forward or back, then tighten all four
screws to secure the unit in place.

Split mode (IN3214 only) — When the IN3214 is
configured for split mode, this female BNC connector
provides an input connection for a second signal source,
either composite video or an S-video C or Y input. See
Normal and Split Mode (IN3214 Only) for more details.
Gain control — Use a tweeker to adjust the amount of

amplification that is added to the video signal. The
adjustment range, assuming a 1.0V input, is from 0.7V (30%
