Product Overview
Description
The IN1404 is a full-featured video and RGB scaler that combines digital video decoding, advanced
video scaling and a 4-input A/V switcher into a single product. The IN1404 uses sophisticated digital
video decoding and scaling technology to convert a composite video, S-video, interlaced or
progressive component video signal and RGB signals (at various scan rates and resolutions) to
standard VGA and HDTV resolutions and refresh rates.
Features
Superb Video Scaling Technology — Employing sophisticated video de-interlacing, scaling and
filtering techniques, the IN1404 offers an output signal with outstanding image detail and enhanced
brightness that is entirely free of visible scan lines. The scaler automatically senses the origin of the
video source material and selects the optimum motion compensation formula to eliminate unwanted
artifacts in the output image. The IN1404 employs high bandwidth digital signal processing, high
speed digital to analog conversion, and sophisticated filtering and sharpness circuitry to maintain and
enhance image detail, even at the highest output resolutions.
Advanced Quad Standard Video Decoding — A high quality video decoder in the IN1404 provides
accurate video decoding of composite video and S-video signals in the NTSC, PAL, SECAM and NTSC
4.43 video standards. The video decoder employs an advanced 3-line adaptive comb filter for
composite video signals and greatly reduces cross-color interference and hanging dots, while
maintaining maximum image bandwidth and detail.
Advanced RGB Scaling — The IN1404 also provides superb upscaling and refresh rate changing for
640 x 480, 800 x 600 and 1024 x 768 resolution RGB video signals, making it an excellent companion for
LCD and DLP display devices that have marginal, on-board video scaling capability. The unit can
accept standard and non-standard RGBHV, RGBS and RGsB signals at horizontal scan rates from
15 KHz - 60 KHz and scale them up to the desired resolution and refresh rate.
Selectable Output Resolution — The IN1404 offers a wide range of output resolutions to match the
optimum or native resolution of virtually any display device. The IN1404 provides a progressive scan
output signal at standard resolutions and refresh rates, ensuring optimal compatibility and
exceptional image quality with a wide range of CRT, LCD, DMD, ILA, D-ILA, and plasma display
devices.
Selectable Refresh Rate — The IN1404 output vertical refresh rate is adjustable from 60 Hz to 120 Hz.
By converting PAL (50 Hz) and NTSC (60 Hz) input signals to higher, more ergonomic refresh rates,
the scaler makes it possible to display a remarkably solid, flicker-free image when using CRT monitors
and projectors. The chart on page 22 indicates the available output resolutions and refresh rates.
4-input Video / Audio Switcher — The IN1404 provides multiple inputs and flexible switching
capability to accommodate a variety of applications. Inputs 1 and 2 can each accept a composite video
or S-video signal. Inputs 3 and 4 accept composite video, S-video, component video, progressive
component video, RGB, RGBS, or RGBHV signals. Inputs 3 and 4 can also be set for passive mode in
which they provide no decoding, scaling or refresh rate changing. Stereo audio-follow-video
switching is provided for all four inputs.
Digital Freeze Frame — Provides a high quality still image for applications that require close
examination of a specific video frame. Freeze frame operates for video signals and RGB signals that
are being routed through the RGB scaling circuitry. Freeze is not available when the input is
configured for RGB passive.
Video Blank button — Located adjacent to the Input Select buttons, the BLANK button allows the
video image to be suppressed. When blank is engaged, the output signals go to black; but the sync
signals continue, ensuring that the data display device retains sync lock. When the BLANK button is
pressed a second time, the previously selected input is once again displayed. The blank feature can
also be engaged or disengaged using an RS-232 serial command. Video blanking is not available when
the input is configured for RGB passive.

IN1404 User’s Manual
On-screen Menus — Provide easy control of video adjustments, including hue, color, contrast,
brightness, gamma, sharpness, image size, image position and edge blanking. Individual image
settings can be optimized and stored for each input. Each time an input is selected, all image settings
stored for that input are automatically recalled. The on-screen menus also make it easy to verify and
adjust advanced settings such as output signal resolution/refresh rate/sync format, RS-232 control
options and reset to factory default. System Info is a handy menu option that uses the on-screen
display to show comprehensive information about the input and output signals and scaler settings.
Image Size, Position and Edge Blanking Controls — Individual horizontal and vertical image
adjustments make it easy to precisely fit the active video image to the display area and provide for
multiple aspect ratios. The digital Freeze Frame feature can be activated using a front panel button or
via RS-232 serial commands.
Comprehensive Input Adjustment Controls — Include signal format, aspect ratio and horizontal
tracking. Once adjustments are made to optimize input signals, these settings are stored and
automatically recalled when the same input source is selected again.
Advanced Input Adjustment Controls — Provided to optimize the unit when it is used with
proprietary and non-standard input signals. These input signal adjustments include: Total Pixels,
Active Pixels, Active Lines, horizontal and vertical blanking, Phase and Scan Type. Once adjustments
are made to optimize non-standard input signals, these settings are stored and automatically recalled
when the same input signal is encountered again.
Blue Screen Feature — Provides a full screen blue image for setup and testing purposes. The blue
screen output signal (activated via the on-screen menu) is always available, even when the input
signal is missing or the input settings are incorrectly adjusted. Blue screen acts as a test signal and is
ideal for setting up the output resolution, refresh rate and position settings, and to verify connection to
the output display device.
128 User Memories — The IN1404 includes 128 user memories that store all video, audio and input
parameters. User memories allow the unit to be optimized for a large number of sources and gives the
capability to recall those settings quickly. The user memories make it easy to expand the number of
inputs by using a switcher or matrix switcher before the IN1404.
RS-232 Serial Control — Provided for all scaler functions, including input selections, image
adjustments and output settings. The IN1404’s comprehensive RS-232 control capacity facilitates
complete system integration and effortless control when combined with a third party control system.
Data Display Friendly Output — The IN1404 provides a progressive scan RGBHV output at standard
VGA resolutions and refresh rates, ensuring optimal compatibility with a wide range of CRT, LCD,
DMD, ILA, D-ILA, and plasma display devices.
Dual Outputs — The IN1404 features a 5-BNC output and a 15-Pin HD (VGA) output. Since both are
active simultaneously, the IN1404 can directly drive two separate display devices.
Rack Mountable — The IN1404 can be mounted in a 1U rack space using the provided mounting
brackets (Extron part # 70-391-01).
Compatibility
Input
The IN1404 Video Scaler accepts composite and S-video signals in the NTSC, PAL, SECAM and
NTSC 4.43 video standards on all four inputs. Inputs 3 and 4 also accept interlaced and progressive
scan component video, interlaced and progressive scan RGBHV, RGBS or RGsB analog video signals
at horizontal scan rates from 15 kHz to 60 kHz. When inputs 3 and 4 are set for passive mode, they are
compatible with virtually any signal format at any resolution and refresh rate within the range of
15-60 kHz.
The IN1404 has stereo audio-follow-video capability. All four stereo audio inputs are compatible with
unbalanced line level signals from a VCR, DVD player, computer audio card, or any other audio

Increasing the sharpness setting produces the visual effect that the noise filter setting is decreasing.
Although the sharpness and noise filter settings seem to offset each other, they are actually two
different adjustments that affect two different sets of circuitry. Operators should adjust both
settings until optimal picture quality is achieved.

If the following settings seem confusing, we recommend that you experiment with the MENU,
, , ,
control operations. It’s a good idea to get comfortable using these buttons to navigate through the
on-screen menu system before moving on to other sections of this manual. If you get lost, enter
unfamiliar territory or are afraid of making an improper selection, pressing the MENU button
allows you to leave the menu system safely without making any changes. We also recommend,
unless you’re a qualified audiovisual technician, avoiding the Advanced menu.
Gamma: The 30 active gamma correction curves programmed into the IN1404 are used to compensate
for the non-linear response of many display devices. Before you adjust Gamma, the brightness and
contrast controls should be set at factory default positions. Once the proper gamma setting has been
achieved, the brightness and contrast settings should then be optimized to fine tune the image.
Range: 1 to 30
Factory default setting: 10*
Operation:
Press
button to step to higher numbered gamma curves.
Press
button to step to lower numbered gamma curves.
* The factory default setting of 10 refers to a gamma correction curve of 1.0.
Noise Filter changes the input signal noise filter. This applies to composite, S-video and component A
signal formats only.
and ENTER buttons until you familiarize yourself with the IN1402 front panel
Range: 0 to 47
Factory default setting: 9
Operation:
Press
button to increase noise filter.
Press
button to decrease noise filter.
Increasing the noise filter setting produces the effect that the picture sharpness setting is
decreasing. See the Sharpness section on the previous page.
Comb/Trap Filter selects either the comb or trap filter (only available with composite video). The
comb filter electronically provides excellent Luma/Chroma separation (separates the color from the
picture signal). This greatly reduces cross-color interference and hanging dots while maintaining
image bandwidth and detail. This applies to composite, S-video and component A signal formats
only.
The trap filter extracts luminance from the picture. Generally speaking, the trap filter is usually the
preferred setting when running signals from a VCR (as composite video). You may wish to compare
both settings to determine which is best for your application.
Reset Video resets all video settings to factory default (for current input only).
Audio menu
The IN1404 allows you to manually adjust the bass, treble, and balance settings. To access the audio
