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.

Compatibility

INPUT

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:

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.

Manual Emulation Sense Pin Selection

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:

JP6: Jumper Connects 2 Lower Pins
