Product Overview
DESCRIPTION
The IN3260 is a distribution amplifier for high-resolution computer video and stereo audio signals.
This unit is specifically designed to mount in a wall, conference table or podium in a standard 3-gang
junction box (included). The IN3260 accepts the high-resolution video signals from a computer
graphics card and the stereo audio signals from a computer sound card, then splits and amplifies the
signals so they can simultaneously drive two data grade displays and two audio devices. The most
common application for the IN3260 is to provide signals for a local monitor and a second display
device such as a data / presentation monitor or projector.
FEATURES
Easy Operation - The user simply brings in a computer and connects video and audio cables to the
nearest IN3260 distribution amplifier. This design eliminates the need to have a power supply,
distribution amplifier and thick output cable dangling from the computer, and promotes easy operation,
enhanced reliability, and a clean, high-tech look.
Modular Wall Plate - Available with a variety of popular connectors, the IN3260 faceplate can be
interfaced with up to three A/V modules. The unit can hold double size plates to accommodate large
connectors such as XLR. The IN3260 simplifies the design and installation process since a single unit
fills the function of both video / audio distribution amplifier and A/V wall plate.
15-Pin HD VGA Standard Connectors - The IN3260 connects directly to VGA graphics cards and
local monitors by using high-resolution coaxial VGA extension cables such as the IN8000 series. Input
/ output adapter cable sets are also available in a variety of lengths for MAC (15-Pin D), SUN (13W3),
SGI (13W3) and workstations (4 or 5 BNC).
Ultra High-Resolution Amplification - The IN3260 provides superb performance and maximum
image clarity at any resolution. Several design elements combine to provide this level of performance:
video bandwidth in excess of 400 MHz, a buffered local monitor output, and input / local monitor
output cables constructed of high-resolution coaxial materials.
Adjustable Video Output Gain - is a feature that boosts the output signal voltage to compensate for
signal loss occurring in long cable runs. Two separate sets of jumpers allow the installer to set unique
output gain levels as required for the Local Monitor Output (15-Pin HD on front) and the Main Output
(6-BNCs on back).
Sync Format / Polarity Preservation - The IN3260 output signals have the same sync format and
polarity as the input signal, ensuring excellent operation with a wide range of CRT, LCD, DMD, ILA
and plasma data display devices.
Stereo Audio Signal Balancing - The IN3260 provides stereo buffering and balancing to support
multimedia applications. The 3.5mm audio input jack accepts unbalanced stereo audio from the
computer sound card and splits / amplifies the signal. One output connector can feed a local audio
device such as powered speakers or an audio / video recorder, while the other can supply the line level
audio signal to a presentation monitor or house sound system. The local audio output is a 3.5mm stereo
mini jack that provides an unbalanced output signal. The main audio output (located on the back side
of the unit) is provided on a 5-pin creative screw terminal and can be set for either a balanced or
unbalanced output signal.
The IN3260 Installation Distribution Amplifier operates with analog video input from a wide
variety of IBM and compatible computer video signal formats including VGA, SVGA and XGA.
OUTPUT GAIN
To set the output gain for the main or local monitor outputs, close the appropriate jumpers
according to the table below. Be sure that the Red, Green and Blue output jumpers for each output
are all set to the same setting. The factory default setting for both outputs is unity gain.

MONITOR EMULATION
Setting the jumpers according to the table below will configure the unit for automatic or manual
emulation:
Emulation for 15-pin HD
Male Input Connector
Pin 11 JP1 Open JP1 Closed
Automatic Factory Emulation (Factory Default)
When the unit is operating in automatic emulation mode, emulation sense pins are treated in the
following manner:
• Monitor Connected to Local Monitor Output - All sense pins are passed from the input
connector to the local monitor output connector, allowing the monitor to set the emulation
automatically.
• No Monitor Connection to the Local Monitor Output - The distribution amplifier
emulates a VGA Color / MAC 13” RGB monitor automatically.
The IN3260 cannot automatically emulate some MAC monitors. Some newer MAC G3 / G4
models require jumper pin 11 to be grounded in order for the PC to boot-up. Manually adjusting,
or grounding jumper pin 11, allows the user to force the video card into the proper configuration. If
so desired, grounding pin 11 on the video output connector [15-pin HD male] will achieve the same
results.
Note: JP2 must
be closed.
STEREO AUDIO BUFFER OPERATION
The IN3260 accepts unbalanced stereo audio signals applied to the 3.5mm stereo mini audio input
connector. This signal is amplified and split into the Local Audio and Main Audio Outputs as
indicated in the chart below:
Connector Type /
Location
Signal Format
Local Audio Output
The IN3260 outputs unbalanced stereo audio at the local audio connector, permitting a local audio
device such as powered speakers, an audio / video recorder or teleconferencing codec input to be
connected.
Main Audio Output
The main audio output is a 5-pin captive screw terminal located on the back of the video
distribution amplifier. The factory default signal for the main output is unbalanced audio. By
setting the jumpers (JP#) to the appropriate positions, the main output can be set for balanced
audio (see illustration on page 4). This is desirable for systems where the audio signal will be
connected to equipment with balanced audio inputs, and is helpful in preserving signal integrity
and minimizing outside signal interference when sending the audio signal over lengthy cable runs.
The main audio output can be set for balanced or unbalanced output by setting the four jumpers as
indicated below:
Unbalanced Output Signal (Factory Default)Balanced Output Signal
CAUTION: Installation of the IN3260 must only be carried out by qualified technicians. Care
must be taken to avoid static shock to the internal components.
This section offers step-by-step instructions for installing the IN3260. The front panel connector
diagram on page 8 shows the location and function of the IN3260 connectors. An application
diagram is included on page 7.
1. Install the junction box in accordance with standards set forth in the National Electrical
Code. Secure the junction box with nails (2 places minimum) if mounting to a wooden
stud or self-tapping screws when attaching to a metal stud. You may also install the
interface in an
existing 3-gang junction box. Run the video coax cable, power cable and stereo audio cables
(if used) to the junction box.
2. Connect the IN3260 output (6 BNC connectors) to the data display device’s RGB input, using
four, five or six high-resolution BNC cables or a multi-conductor RGBHV, RGBS, or RGsB
"snake" (most installations will require five or six connector cables). The IN7000 Series, IN7200 Series, IN7300 Series and IN7400 Series high-resolution cables are well suited for
this purpose (see RGB INSTALLATION CABLE table on page 12). Take care while making
connections to ensure that the red output is connected to the red input, sync output to the sync
input, etc.
3. Connect the left, right and ground conductors on the audio cable to the IN3260 3-pin mini
Phoenix connector (J4). This connector will accept stranded or solid cables from 20 - 26
AWG.
4. Connect the power cable to the unit. The power connector has a sticker showing the correct
polarity. Be extra careful to connect positive to the (+) connector and negative to the (-)
connector. Connecting the power with reversed polarity may permanently damage the
unit! If in doubt, measure the power cable with a voltmeter to verify positive and
negative. The IN9204 9 VDC 500 mA power supply (included) will power one IN3260. You
may also use the optional IN9210 rack mounted power supply which will power up to 10
amplifiers. The power cable used to connect the power supply to the unit should be 18 gauge
to 22 gauge, depending on the length of the cable. INLINE offers the IN8500P-2 power cable,
an 18 gauge, 2-conductor, plenum rated cable.
5. The factory default setting is auto power disabled (P3 jumper placed on left pin and center pin)
meaning that the amplifier is powered up as long as 9VDC power is applied. If you want to
use the auto power (unit automatically powers up when the input cable is attached), move the
P3 jumper to cover the center pin and right pin (see illustration on previous page).
6. Carefully attach the IN3260 to the outlet box making sure that no cables are pinched or
damaged.
7. Turn the computer and computer monitor off. Disconnect the computer monitor (if present)
from the video output port on the computer.
8. Connect the local computer monitor (if present) to the local monitor output of the IN3260.
VGA monitors will attach directly to the local monitor output. For other types of monitors,
use the appropriate local monitor output adapter cable (see list on page 13). No termination is
required if the IN3260 is use without a local monitor.
9. Connect the computer graphics card video output to the IN3260 Input using the appropriate
input cable (see list on page 13).
10. Connect the computer sound card output (if present) to the audio input connector using an
IN9106 audio patch cable. For computers with RCA connectors, use the IN9107 audio
adapter cable.
11. Complete the installation by turning the computer and computer monitor on.

Problem: The display device connected to the IN3260 output has a bad/scrambled
image.
Solution 1: Verify that the correct input cable is being used (see the table on the previous
page).
Solution 2: The display device connected to the output of the interface may not be compatible
with the computer output. Standard 640 x 480 VGA runs at 31.5 KHz, but SVGA
can be as high as 48 - 58 KHz depending on the vertical refresh rate. PC, MAC,
Sun and other high resolution workstations have new ultra high resolution modes
such as 1600 x 1200 and 1800 x 1440 and can output a video signal with a
horizontal scan rate of over 100 KHz! Many data monitors and data projectors are
not compatible with these resolutions and frequencies.
Solution 3: The RGBS or RGBHV cable may have a bad sync line. Try running the sync
through another cable (i.e. temporarily use the red coax to connect the sync).
Problem: The local monitor looks fine but the image on the LCD projector is wavy or
has vertical bars in the picture.
Solution 1: LCD / DMD displays often have an adjustment called Phase Adjust or Fine Phase
Control. This control should be adjusted to provide the best image.
Problem: The output image is doubled, with two images displayed side-by-side.
Solution: The display device may not be compatible with the horizontal scan rate of the
computer. This problem often occurs when a 31.5 KHz VGA signal is sent into an
RGB monitor that is only compatible with signals at 15.75 KHz.
