Installation

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 loop-

through 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.

Installation

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

Ensure you are using the correct power supply, 110V

or 220V, for your region. Using the wrong power

supply will damage the DA.

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).

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.

5. Replace the cover and reinstall the screws.

Furniture mounting

If desired, furniture mount the unit using the optional IN9127

mounting brackets, as follows:

1. Attach the mounting brackets to the distribution amplifier

with the provided machine screws (figure 5).

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.

Power connector — Plug the 9VDC power supply into this

connector.

CAUTION

Ensure you are using the correct power supply, 110V

or 220V, for your region. Using the wrong power

supply will damage the DA.

Video Output connectors — Connect up to two (IN3212) or

four (IN3214) composite video output devices, such as

projectors, VCRs, or monitors, to these female BNC connectors.

For an IN3214 configured in split mode and distributing

S-video, Outputs 1 and 2 output one video plane (Y or C)

and Outputs 3 and 4 output the other plane (C or Y).

Input 1 connector — Connect a composite video input or

(for the IN3214 only) an S-video Y or C input, such as from

a DVD player or a VCR, to this female BNC connector.

Loop-out/Input 2 connector —

Default configuration — In the factory default

configuration, this female BNC connector is not used.

Buffered loop-through — To provide a buffered loop-

through signal, the internal jumper settings must be

changed (see the jumper table on page 5).

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%

decrease) to 1.4V (40% increase).

Peak/Sharpness control — Use a tweeker to adjust for the

best sharpness.
