DESCRIPTION

The IN3212, IN3214 and IN3218 are high performance video distribution amplifiers with gain and
peaking controls.

• The IN3212 is a 1 in 2 out composite video distribution amplifier / line driver.

• The IN3214 is a 1 in 4 out video distribution amplifier / line driver.

• The IN3218 is a 1 in 8 out video distribution amplifier / line driver.

All three models are very similar in function, features, and operation with only a few differences as
detailed in the chart below:

1

Feature

Number of Outputs­Regular Mode
Number of Outputs­Split Mode
Gain Controls 1 2 4
Sharpness Controls 1 2 4

These units feature a compact design, which allows them to be installed in a very small space, and offer
300 MHz bandwidth performance. The gain and peaking controls can be adjusted to compensate for
signal loss due to long cable runs, and may be used to drive a signal as far as 1000 feet, depending on the
signal resolution and cable. Multiple units can also be looped together to provide additional outputs.

PRODUCT FEATURES

• 2, 4 or 8 Outputs – Feed the signal from one video source to two, four or eight monitors, projectors,

VCRs, or other output devices.

• Gain Controls – Boost the signal voltage to drive long cable runs.

• Peaking Controls – Enhance image by increasing clarity and visibility of fine details.

• 300 MHz Video Bandwidth

• BNC input and output connectors

• Wide Compatibility – Compatible with composite video signals (NTSC / PAL / SECAM) and high

resolution monochrome video signals.

• Split Mode Operation – By changing an internal jumper, the IN3214 or IN3218 can be set for split

mode where they function as two independent Distribution Amplifiers:

- IN3214: (2) 1x2 Distribution Amplifiers

- IN3218: (2) 1x4 Distribution Amplifiers

• Loop Output – The loop output connector provides a passive loop-through signal. This can be

looped through to additional amplifiers to create a larger DA system or to drive a local monitor.

• Metal case enclosure and optional mounting brackets

COMPATIBILITY

The IN3212 / IN3214 / IN3218 offer extremely wide bandpass characteristics and are compatible with
hi-resolution monochrome signals at virtually any resolution and refresh rate, as well as with low
resolution color composite video signals such as NTSC, PAL, or SECAM.

INSTALLATION

1. If operating the IN3214 / IN3218 in unified mode without loop output (factory default,) begin
with step 2. If operating the IN3214 / IN3218 in split mode or with the loop output

connector, please refer to INTERNAL CONTROLS section on page 3 and set jumper as
appropriate.

2. Connect the video signal from the source to the IN3212 / IN3214 / IN3218 input.

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

4. Apply power to the unit (9VDC, 500 mA external adapter.)

5. Adjust gain and peaking controls as needed (see GAIN AND PEAKING CONTROLS
section for details.)

OPERATION

The IN3212 / IN3214 / IN3218 are designed to distribute/extend video signals. These units have gain
and peaking controls which can compensate for cable losses, extending a video signal as far as 1000 feet
without any degradation of the signal. 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 high resolution signals (30 KHz and above) can be sent 200-400 feet.

Regular Mode / Split Mode Operation

The IN3214 / IN3218 can function in two different amplification modes, regular mode or split mode as
described below:
Regular Mode (factory default): The unit operates as a single amplifier. The input signal drives all
four or eight outputs. The second connector adjacent to the input may be used as a loop output if the
internal jumpers are set properly.

Split Mode: The unit operates as two independent amplifiers. Each input drives two outputs (IN3214)
or four outputs (IN3218). In split mode operation, the IN3214 / IN3218 can be used to amplify two
separate composite video signals or to amplify a single S-Video signal, with the Y (luminance) signal
connected to one input connector and the C (chrominance) signal connected to the second input
connector.

Please note that in split mode there is no loop output connector since the second connector is used as an
input. However, if a loop output is required, the inputs can be set to High Z termination using the
internal jumpers and a BNC "T" can be used to split the signal at the input.

IN3212 / IN3214 / IN3218 OPERATION MANUAL - REV. 1 10/25/97 ©1997 - INLINE, INC.

LOOP OUTPUT CONNECTOR

The loop output connector provides a passive loop-through signal. This can be looped through to
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). The location of the
input termination jumper is indicated on pages 4-6.

GAIN AND PEAKING CONTROLS

The gain controls can be used to compensate for video signal voltage losses. Peaking may be used to
reboost high frequency components that have been attenuated by long cable runs. The peaking control
employs an equalization circuit, introducing an adjustable high frequency peak.

Gain Control

The gain control is used to increase/decrease the contrast of an image by adjusting the amplitude of the
video signal. The control has a range of 0.7 to 1.4. Using the IN9333 adjustment tool, gently turn the
control clockwise to increase the video gain, and counter-clockwise to decrease the gain.

Peaking Control

The peaking control enhances image detail and sharpness by boosting high frequencies. Using the
IN9333 adjustment tool, gently turn the control clockwise to increase peaking, and counter-clockwise to
decrease the peaking.

INTERNAL CONTROLS

CAUTION: Adjustment of the IN3212 / IN3214 / IN3218 internal controls must only be carried out
by qualified technicians. Care must be taken to avoid static shock to the internal components.

The IN3212 / IN3214 / IN3218 have internal jumpers which can be accessed using the following
procedure:

1. Remove the screws from the sides of the unit.

2. (For IN3212 / IN3214 only) Remove hex-nuts from the output BNC connectors.

3. Slide the top cover off.

4. Identify location of jumpers using the diagrams on pages 4-6 and adjust as needed.

5. Replace top cover and tighten the BNC hex-nuts (if applicable) and the side screws.

TROUBLESHOOTING

Problem: There is no image on the output of the IN3212 / IN3214 / IN3218.
Suggestions:

q Make sure the power supply is plugged in and that the input and output cables are

connected properly.

q Bypass the IN3212 / IN3214 / IN3218 by connecting the input and output cables

with a BNC barrel connector to ensure there is a video signal present.

Problem: The output image is too dark.
Suggestion:

q First make sure the display device contrast and brightness controls are set properly.

Then increase the appropriate IN3212 / IN3214 / IN3218 gain control until the
desired image is achieved.

Problem: The output image is too bright or the picture blooms.
Suggestions:

q First make sure the display device contrast and brightness controls are set properly.

Then decrease the appropriate IN3212 / IN3214 / IN3218 output gain control until
the desired image is achieved.

q The input termination may be set to High Z. Check the termination jumper settings

(see pages 4-6.)

Problem: The output image is not sharp enough. Vertical lines are very thin.
Suggestions:

q Make sure you are using the appropriate video cable for your signal type. When

dealing with high resolution video signals, a high quality coaxial cable must be used
for long distance cable runs (50 ft. or more). IN7100 or IN7200 series cables are
recommended for very long cable runs.

q Increase the peaking control of the IN3212 / IN3214 / IN3218 to compensate for

high frequency losses.

Problem: The loop output is not working.
Suggestion:

q The input termination for input 1 must be set to High Z. Set the internal jumpers as

shown on pages 4-6.
